Halotestin: A Complete Guide To Halo’s Results, Effects, and Other Information

The anabolic steroid known as Halotestin (Fluoxymesterone) is considered to be among the most potent on the market. Because of its narrow application, halotestin has not enjoyed the same level of popularity among bodybuilders as other anabolic steroids, despite the fact that it is quite powerful.

Because it is so effective at increasing strength, halotestin has a place in the hearts of athletes who compete in strength sports. However, as we will see, this great benefit does come with some significant drawbacks, which greatly reduces its desirability for most bodybuilders.

Should you be adding Halotestin to your cycle? Read on to find out.

What is Halotestin?

Halotestin, or Fluoxymesterone, is an androgenic steroid used in medical settings to treat testosterone deficiencies. Because of its status as an anabolic steroid, Halotestin has garnered the interest of both bodybuilders and sportsmen in recent years. The generic medication fluoxymesterone is sold under the brand name Halotestin. When bodybuilders use this substance, they see a surge in the growth of their lean muscle mass. Therefore, it is clear that many who are considered to be fitness gurus are abusing this substance.

The hormone halotestin is administered to males who have problems with delayed puberty as a result of the insufficient synthesis of testosterone in their bodies naturally. This hormone supplement helps the growth of muscle, enhances bone density, and strengthens the male reproductive system.

Professional bodybuilders don’t use it that often, and when they do, it’s usually just a few times in the days just before a contest. It is more likely to be encountered in combat sports or other types of activities where gaining weight might be problematic.

On paper, Halotestin boasts some of the highest androgenic and anabolic ratings of any steroid. It is reasonable to imagine that if you took them, you would experience unfathomable growth in size and strength in a very little amount of time.

In the actual world, check drops are handled quite differently. Even though the anabolic rating is more than twice as high as the androgenic rating, the anabolic effects are much more modest. This is because they are predominantly an androgenic steroid, and as a result, their effects are more androgen-based.

People who have a low body fat percentage can use halotestin to raise their aggressiveness before a powerlifting competition or a fight. These supplements are also excellent for enhancing strength and muscular density, and they give the muscle a hard, blocky appearance. They are not truly all that effective when it comes to putting on muscle.

Adverse effects may become more prevalent and frequent when used without proper precautions or run for extended periods of time at higher doses.

Complete History of Halotestin

In the late 1950s, Upjohn began selling fluoxymesterone as a powerful anabolic androgen steroid under the brand name Halotestin. Fluoxymesterone is known for its exceptionally high level of anabolic activity.

Shortly after that, Ciba Pharmaceuticals introduced the hormone to the market under the brand name Ultandren. Nonetheless, Halotestin remained the most well-known among consumers.

This powerful anabolic steroid is used to treat various conditions, including male pattern baldness, low testosterone levels, damage to muscle tissue, starvation, and broken bones. In addition, this highly effective anabolic steroid is used to treat and prevent androgen deficiency.

In contrast to most anabolic steroids, halotestin is commonly administered to both men and women. Its usage is slightly restricted in today’s world, but it is nevertheless employed in treating breast cancer in select female patients. 

Although it is uncommon, the hormone can now be used in the treatment of osteoporosis in certain postmenopausal women. However, it is still employed as therapy for androgen shortage problems in male patients.

In the realm of performance enhancement, halotestin is known for having the reputation of being one of the steroids that is both the most potent and acts the quickest.

It is a synthetic derivative of methyltestosterone. Testosterone is the parent hormone (methylated testosterone). It is thought of as a very potent oral anabolic steroid hormone that cannot be converted to estrogen and possesses a very potent androgen intensity. In addition, it cannot be aromatized. The level of halotestin’s androgenic strength is 850, whereas its level of assimilation strength is 1900. Compared to the hormone from which it was derived (testosterone) it is easy for everyone to understand how potent halotestin is in terms of its anabolic muscle-building capability and its ability to produce androgens.

In comparison, the anabolic and androgenic effects of testosterone are each equal to 100, however, the incredible strength of halotestin is 19 times that of testosterone, and its androgenic activity is 8.5 times that of testosterone. Because of this, Halo is a very potent anabolic and an extremely potent androgen. It is more potent than trenbolone, the most powerful traditionally available anabolic steroid that can be purchased over-the-counter.

Medical practitioners prescribe halotestin to both men and women. It has been demonstrated to treat insufficient androgen production in males, often known as hypogonadism or andropause. The FDA has given its approval for the use of Halo in the treatment of persistent dysfunctional uterine bleeding in women as well as breast cancer in women.

The list of approved therapies for halotestin was created in the mid-1970s and 1980s. The FDA has imposed several limitations and restrictions. In later years, the list of conditions for which halotestin was approved as a treatment was narrowed down to include only androgen shortage in males, breast cancer in women, and, to a lesser degree, osteoporosis in postmenopausal women. Today, only the treatment of androgen deficiency in males and breast cancer in women are now on the list of approved medical applications for halotestin. This is because the list of approved medical uses for halotestin has been further limited today.

The problem with Halo is that it possesses a high hepatotoxicity level, which is likely to modify a users cholesterol profile unfavorably. Because of these drawbacks, physicians and other medical experts have decided to avoid employing halotestin for treating conditions other than male androgen insufficiency. The use of halotestin in androgen replacement treatment or hypogonadism is similarly restricted in basic TRT (testosterone replacement therapy) because the administration of simple testosterone is less hepatotoxic than the administration of halotestin. Halotestin is still made by its original manufacturer, Upjohn, for the prescription market in the United States. However, the medication is currently marketed under the brand name Pharmacia.

How Does Halotestin Work?

Since halotestin is a derivative of testosterone, its ability to stimulate protein synthesis in the body can be expected to increase. Because it does not aromatize into estrogen-like testosterone, it is an excellent choice for use during bulking cycles. It is very similar to testosterone.

The muscles will become denser, drier, and more vascular due to this. Because it produces excellent results in a relatively short amount of time, halotestin is an excellent choice for athletes and powerlifters who need to boost their speed and aggressiveness while they are in the course of their training. It does this by increasing the amount of blood that flows to the muscles, leading to more intense workouts and better pumps.

Because of this, some users liken it to an injectable form of Anadrol, a strong anabolic steroid. Because it reduces the amount of lactic acid that is produced in the muscles, the steroid is also helpful for endurance athletes. This results in increased stamina, which is beneficial for training for longer periods.

You can use halotestin by itself during cutting cycles, or you can combine it with testosterone to use it during bulking cycles. Not only will this cause fat to be burned, but it will also prevent muscle tissue from being damaged and improve strength gains. Most people who use Halotestin claim that they see a significant improvement in their bench press, squat, and deadlift numbers after using this drug for only a short amount of time. This improvement is attributed to increased aggression and strength while working out. When performing endurance training, increasing the number of reps is very beneficial because it decreases fatigue, allowing you to make more reps. This increases the number of reps you can perform.

Some athletes claim that the steroid makes them feel as if they are almost high on drugs while also giving them increased aggression for maximum performance in anaerobic activities. This is because the steroid has a very fast-acting time. Because it reduces the production of lactic acid in the muscles, it is also effective for endurance training. This results in improved stamina as well as a faster recovery time overall. Because it has a 320 anabolic rating and a 300 androgenic rating, it is ideal for athletes who want to improve their work capacity, stamina, or strength.

Possible Side Effects of Halotestin

When it comes to the risk of side effects, halotestin is not a particularly dangerous steroid. There are a lot of other compounds out there that are much worse. On the other hand, is not a very user-friendly compound, especially when considering its hepatotoxicity and the potential adverse effects it could have on cardiovascular health.

Halotestin is an anabolic steroid hormone that is derived from testosterone; however, it does not aromatize and does not cause estrogen-related side effects. A few other compounds in the cycle might call for anti-estrogen, but this is not necessarily because halotestin is being used.

Since Halo is an extremely androgenic steroid, the potential negative effects of halotestin may be surrounded by a strong androgenicity.

These effects depend on the individual’s response and their genetic make-up; however, the androgenic effects of Halo significantly increase its potential.

The 5′-reductase enzyme, which is also involved in the process of reducing testosterone to dihydrotestosterone, has a significant impact on the formation of halo testosterone. Therefore, the use of 5-reductase inhibitors like finasteride, which may be able to reduce the androgenic side effects that are associated with halotestin, can be beneficial.

The androgen activity of this steroid is not entirely diminished by such use, but there is a possibility that it will reduce the activity.

Even with the use of this steroid, its androgenic effects may not be completely eliminated, leaving a potential for some residual activity. However, there’s a chance that its overall impact could be diminished with consistent use. It’s crucial to be mindful of potential effects and consult with a professional.

Misuse of halotestin may lead to increased blood pressure. It’s essential to use this steroid under professional guidance to minimize potential side effects. Monitoring blood pressure regularly and adopting a responsible approach to its use are crucial for overall health and well-being. Always consult with an experts.

Suppose the person’s health is good enough for use. In that case, it is absolutely necessary for him to do everything in his power to maintain healthy levels and carefully monitor how they change over time.

The management of this condition should involve maintaining a very healthy lifestyle, consuming a diet that is abundant in omega fatty acids, and eating in a way that is generally cholesterol-friendly.

One of the negative effects of halotestin is a significant reduction in the body’s naturally occurring testosterone levels. Those who supplement their routine with exogenous testosterone will not experience this low-level effect.

After stopping the use of Halotestin and waiting until all exogenous steroid hormones have been eliminated from the body, the body will restart its production of natural testosterone. The occurrence of prior low-level conditions is not necessary for natural recovery.

Halotestin is a C17 Alpha-alkylated (C17aa) anabolic steroid hormone. This refers to structural changes that take place at the 17th carbon position. Of all the C17aa oral anabolic steroids, halotestin has one of the most potent hepatotoxicity.

The utilization of this steroid results in an increase in liver enzyme levels, most likely to a significant degree. Before using halotestin, one must ensure that their liver is in good health.

Halotestin Dosage Recommendations

A significant number of anabolic steroids offer a wide range of dosing options, enabling even inexperienced athletes to achieve results comparable to those more seasoned athletes by simply increasing their dosage.

When it comes to Halotestin, our options are constrained due to this steroid’s potency, and doses should not be increased beyond a certain level. Engaging in such behavior exposes one to significant dangers to one’s health, particularly regarding one’s liver and cholesterol levels. This places a significant restriction on the dosing range available to you compared to other steroids.

In addition, regardless of the dosage you select, there is not much wiggle room regarding the length of time that using Halotestin is considered safe. Here are some common examples of how much Halotestin should be taken and how it is used.

Doses of Halotestin for Beginners, Intermediates, and Advanced Users

Because of its restricted benefits and its side effects, halotestin is not likely to be a steroid that beginner steroid users or even intermediately experienced steroid users will want to consider using. If, on the other hand, a beginner is set on beginning a Halotestin cycle, the safest dosage range to stay within is between 10 and 20 milligrams per day. Even at the low dose of 10mg, you can expect very noticeable results, and a beginner’s use period shouldn’t go beyond two weeks to minimize adverse effects on the liver.

Intermediate users will still see excellent results from as little as 10mg or 20mg per day; however, some may increase their dosage to 30mg per day for increased strength and boosts to drive to enhance their performance. When increasing the dosage to 30 milligrams, close attention should be paid to both the liver and cholesterol levels because there is a virtually guaranteed increased risk of toxicity.

It’s possible that advanced users will be tempted to take extremely high doses of Halotestin to boost its effects even further, but doing so is neither the correct nor the safest way to use this steroid. The highest dose of halotestin that is considered safe is 40 mg daily. Anything above this level puts you at an extremely high risk of experiencing damage to your liver.

Advanced steroid users will see significant effects with just 20 mg daily of Halotestin. However, once you have become accustomed to the steroid and are looking for more extreme effects by increasing the dose, there is only a small window of opportunity, and 40 mg is considered to be the maximum safe dose of Halotestin. Anyone who takes more than 40 milligrams of halotestin per day is putting an unnecessary strain on their liver, regardless of their level of expertise or experience.

Halotestin, which typically comes in doses of 2.5, 5, and 10 mg, has a half-life of approximately 9 hours.

Even though it has extremely high levels of both androgenic and anabolic properties, Halo is not a compound that is frequently used by bodybuilders. This is because Halo does not stimulate a significant amount of growth in the muscle tissue, and even though it has good “hardening” effects, there are simply better compounds available that carry a lower risk of adverse effects.

Because Halo does not aromatize to estrogen, there is no risk of developing estrogenic side effects like gynecomastia or water retention when using this product.

Halotestin: How to Cycle

Halotestin is a very potent steroid, particularly in the androgenic department; however, unlike many anabolic steroids, it does not come with the versatility many of these drugs possess. Because of this, how it can be used during a cycle to achieve the greatest possible benefit with the fewest possible adverse effects are quite restricted.

Halotestin is not used as the primary anabolic compound, and it should not be used by itself or even in conjunction with low doses of testosterone. This is because Halotestin does not have powerful anabolic effects. In conclusion, due to the potentially harmful effects that Halotestin has on the liver, the drug can only be used for a limited time period during a steroid cycle. This is yet another factor that places restrictions on the use of Halotestin. The following is a list of some sample cycles that illustrate the use of Halotestin by users of varying experience levels:

Beginner Cycle

Beginners to halotestin should limit their use of the compound to include testosterone as the only other steroid in the cycle at a dose that will both provide lean gains and a source of testosterone that will be essential while halotestin is suppressing normal function. This dose should be at a level that will give both of these benefits. The combination of Testosterone Enanthate at a dosage of between 300 mg and 500 mg per week and Halotestin, which provides the strength and drive necessary to push through your workouts, will result in some nice mass gains.

Although testosterone can be administered throughout the entire duration of the cycle (which is 12 weeks), halotestin should only be used for the first four weeks in order to deliver the desired results. This particular cycle can be thought of as a bulking cycle. Despite the fact that it is not common, users will discover that Halotestin offers a distinctive experience in comparison to that offered by some of the more conventional steroids that a novice might choose to use.

Intermediate Cycle

The well-known steroid deca-durabolin, which does not aromatize and is therefore not likely to cause the user to retain excess water, is included in this 12-week cycle of anabolic steroids. As a result, the user will be able to experience gains and improvements to their physique without the risk of developing a puffy appearance. In this cycle, testosterone is used solely as a supportive compound at a low enough level to be useful but not at a high enough dose to result in rising estrogen. The level of testosterone used is just low enough to be useful. Testosterone is administered at a dosage of 100 milligrams per week, Deca Durabolin is administered at a dosage of 400 milligrams per week throughout the entire cycle, and Halotestin is administered at a dosage of 30 milligrams per day for only the first four to six weeks, at most, of the cycle. The intermediate user can anticipate quality gains in mass during this cycle.

Advanced Cycle

Only the most experienced users will even consider using this cycle, which includes the use of Halotestin for a period of time that is significantly less than half the total duration of the cycle. This drug is used in the cycle’s final weeks with the primary objective being to achieve maximum hardness of the physique; however, with the addition of Trenbolone Acetate, some mass gains as well as fat loss can also be targeted.

This cycle is specifically designed for those who are competing in contests, as the cycle will prepare you for the competition in the lead up to the event. Tren is considered to be a steroid that is only appropriate for very experienced users—achieving maximum definition and hardness while retaining no water and having a minimal amount of body fat is required for this.

Again, Testosterone Propionate or any other testosterone ester acts as testosterone support at a dosage of 100 milligrams per week for the entire ten weeks, in conjunction with Trenbolone at a dosage of 400 milligrams per week. Only in the final four weeks of the cycle, at the maximum safe dose of forty milligrams per day, should halotestin be added.

Halotestin Stacking Recommendations

Because of the powerful suppressive effects that it has, the anabolic steroid halotestin needs to be combined with at least one type of testosterone before it can be used safely. This is the most fundamental stack possible, and it includes Halotestin. People who are using Halotestin for the purpose of pre-contest hardening will find that stacking this steroid with another very powerful androgen like Trenbolone will result in an extremely defined physique. However, the adverse effects can be expected to be just as extreme, which is why such a stack is only something that the most experienced and advanced users should even consider.

Halotestin: What To Expect

There is a low probability that Halotestin will be a steroid that is a high priority for inclusion in your cycle if you are a bodybuilder. Many regular bodybuilders choose not to use it at all, and the only people who can feel that the benefits of this steroid outweigh the severe drawbacks are those who have very specific goals, such as powerlifters.

On the other hand, the greatest benefits are most likely to be experienced by those who compete in contests and require exceptional definition in addition to the sheer drive and aggression necessary to get them through the final stages of a highly restrictive and strenuous contest.

Because it does not aromatize and is not associated with fluid retention, halotestin offers a unique and specific benefit in that it increases aggressiveness and strength while also making a direct contribution to the improvement of physical conditioning. Because of this, it is common practice for competitors to include halotestin at the very end stage of a pre-contest cycle, when it is most likely to have the greatest effect.

It is important to remember that halotestin has a detection time of about two months, which might not be good for competitive bodybuilders who want to avoid testing positive on random drug tests.

Halotestin: Post Cycle Therapy

The implementation of post cycle therapy is essential if you want to stimulate your natural testosterone production again after having it suppressed while on a Halotestin cycle. Even when compared with other powerful anabolic steroids, the suppression activity of halotestin is extremely potent. Because of this, it is vitally important to prevent damage to the Hypothalamic Pituitary Testicular Axis (HPTA) by limiting the amount of time the steroid is used and the dose. Such damage can make it extremely difficult or even impossible to restore normal testosterone function.

When to begin your post-cycle therapy (PCT) will also be determined by the other compounds in your cycle. A common practice involves co-administration of Nolvadex and HCG (human chorionic gonadotropin) for a duration of six weeks. Because of the extremely potent suppressive effects of halotestin and the fact that it is frequently used for the closing phase of a cycle, post-cycle therapy (PCT) should be extended to a total of 6 weeks rather than being terminated after only 4 weeks, as is possible with some other steroids.

This allows for a sufficient amount of time for the stimulation of testosterone function and helps you avoid falling into a state of low testosterone. If you fall into this state, not only will any gains made start to reduce, but you can also gain excess fat, your energy can be drained, and a variety of health problems can develop. When PCT is complete, your body should once again be producing an adequate amount of its own testosterone.


The primary purpose of taking Halotestin is to accomplish a marked improvement in one’s strength. The majority of people, including bodybuilders and athletes, are not likely to find much use for or benefit from this steroid because it does not have as wide a variety of benefits as other popular steroids.

The primary beneficiaries of its use are male athletes who take part in extreme athletic competitions, such as powerlifting, fighting, and other strength-based events. When compared to some of the more effective anabolic steroids that are currently available, halotestin is not particularly useful for the average bodybuilder.
