Fluoxymesterone is an extremely powerful anabolic androgenic steroid that was first released in the late 1950s by Upjohn under the trade name Halotestin. Shortly after, Ciba Pharmaceuticals would release the hormone under the Ultandren name, but Halotestin has remained the most recognizable brand name. Pharmacia, formerly Upjohn, now manufactures the Halotestin brand name.
When Halotestin first hit the market, it was touted as holding numerous therapeutic benefits. This extremely potent anabolic steroid was prescribed for the treatment of muscle wasting, androgen deficiency in men, lean tissue repair, malnutrition, and for healing bone fractures. It would also be regularly used to treat prolonged exposure to cortisone, paraplegia, breast cancer and often given to burn victims. Unlike many anabolic steroids, Halotestin was regularly prescribed to men and women, and while its modern-day use is somewhat limited it is still used to treat breast cancer in some women. The hormone is still used to treat androgen deficiencies in some men, but it’s rare and is approved for osteoporosis treatment in some postmenopausal women.
In the world of performance enhancement, Halotestin holds a reputation for being one of the most powerful and fast-acting steroids on the market. However, it’s not one a lot of steroid users will use. This steroid will not build a lot of mass despite a massive anabolic rating; in fact, it really won’t do much at all for mass promotion. This is a steroid that is generally known as a raw strength steroid, but Halotestin is also found in some cutting cycles. It’s not too uncommon for some bodybuilders to supplement with Halotestin the last few weeks before a competition. It can produce some nice conditioning effects, as well as really aid in pushing through the end of a brutal diet. However, the side effects of this steroid are no joking matter, they can be pretty harsh, and that will keep most people away.
Halotestin Function & Traits:
Fluoxymesterone is a testosterone-derived anabolic androgenic steroid or more specifically a structurally altered form of Methyltestosterone. Halotestin is the testosterone hormone with an added methyl group at the 17th carbon position to allow oral ingestion. It also possesses an added fluoro group at carbon 9 and 3 and a hydroxyl group at carbon 11. These modifications inhibit the steroid’s aromatization and greatly increase its androgenic nature. The androgenic nature and activity of Halotestin will be far beyond Methyltestosterone.
By its structural design, Halotestin carries an anabolic rating of 1,900 and an androgenic rating of 850. All ratings are measured against pure testosterone, which carries a rating of 100 in both categories. This means Halo as it’s often known carries ratings that are almost beyond reason, but its anabolic rating is tremendously deceiving. While it carries a massive anabolic rating, its anabolic translation in human beings appears to be near zero. This steroid simply doesn’t translate into any notable anabolic effect and will primarily function by androgenic activity.
Halotestin carries with it some tremendously powerful effects, some of the most powerful revolving around red blood cells. Halo has the ability to greatly increase hematocrit and hemoglobin levels as well as red blood cell mass. It also appears to act through cells that are already committed to erythropoietin response. These effects are largely responsible for the strength effects promoted, as well as the increased level of energy the steroid can provide.
Halotestin also carries with it strong fat loss effects. Halo has the ability to promote the regulation of fatty acid oxidation in the liver, as well as fast-twitch muscle mitochondria. Through these traits as well as the red blood cell interaction, we have a steroid that can have a pronounced effect on visual conditioning aspects in an individual who is already fairly lean.
Effects of Halotestin:
The effects of Halotestin, while tremendously powerful do not represent what we’d label a truly versatile anabolic steroid. This steroid carries very specific points of use, and while it can be beneficial the potential side effects will make it unnecessary for most men. The primary effects of Halotestin revolve around strength and aggression. The issue of aggression and anabolic steroids is often blown out of proportion, but in the case of Halo, it truly can enhance an aggressive nature. This in turn can cause the athlete to push harder and be even stronger. While it can enhance aggression there are some important things to keep in mind. Halotestin cannot alter your personality, take away your ability to distinguish between right and wrong, or alter your decision-making process. It can give the individual a stronger, aggressive nature, but what one does with aggression determines if it’s right or wrong. Aggression in itself is not a bad thing, it can be a very positive tool; what we do with aggression determines if it’s right or wrong. For the individual who is naturally violent and angry, the use of Halotestin will make him a more aggressive jerk. For the same individual, he’ll have more aggression to put in the gym or in a competition.
Due to the strength and aggression promotion, this makes Halotestin a popular steroid among powerlifters, strength athletes, and fighters shortly before competition. A few weeks of use leading up to competition is very common, and the boost in strength can potentially be greater than any other anabolic steroid could provide. This same strength and aggression can also be useful to the competitive bodybuilder a few weeks out from his show. Competitive bodybuilding dieting is brutal and perhaps the hardest way to diet on earth. Towards the end, most become extremely drained and have a very difficult time pushing through their training. Adding in Halotestin those last few weeks can help push them through this extremely difficult time. It will also provide the individual with a much harder and more defined look; however, there’s an important note. While Halo can greatly improve visually related conditioning, you must be extremely lean, contest bodybuilding lean to really get anything out of it. Most steroid users will never see this level of leanness and there will be no beneficial purpose of use to them.
This largely sums up the effects of Halotestin regarding beneficial effects. The steroid is not a mass-building steroid, and it’s not one that’s used as a foundational steroid in any cycle. This is a short-term use steroid that carries specific benefits for specific purposes. In a therapeutic setting, while it is approved for some points of treatment, it has become exceedingly rare.
