Halotestin (Fluoxymesterone) is a legendary steroid among weightlifters and brute strength athletes. The simple word Halotestin evokes images of colored pills that instantly transform Dr. Jekyl into Mr. Hyde.
The first thing that you notice is that Halotestin has completely insane anabolic and androgenic effects. This compound is 19 times more anabolic than testosterone and 8.5 times more androgenic.
These numbers are a little deceptive, and Halotestin does not produce as much muscle as simple testosterone. Let’s look at Halo more closely to see what kind of effects you can expect from this product and what types of side effects you might experience.
First, its usage in sports and weightlifting is much more common than in bodybuilding, where it is essentially used as a magic boost in the last few weeks before a bodybuilding competition. It will harden a lean physique and give the user a certain aggression.
Halo has no estrogen-related activity and will not cause water retention or most other harmful estrogen-related side effects. Therefore it is hepatotoxic (toxic to the liver) and we recommend keeping doses around 40mg/day for up to 4-6 weeks.
If you use Halotestin for its pronounced effect on aggression, you can simply take 10mg before a workout session, ideally during the most intense weeks of a bulking or cutting cycle.
Halotestin Effects
Halotestin affects a body’s volume gains,and for people with low percentage of body fat, immediate effects will often be visible.
Halotestin also seems to act through cells that respond to erythropoietin, which is good news for athletes. As you can see, Halo has a profound effect on red blood cell production, which is one of the most obvious ways it increases endurance and energy.
It’s also possible to use it for pure athletics and for sports requiring an elevated VO2 max like rugby, mixed martial arts, combat sports, etc.
Halotestin is an excellent drug for strength gains and increased aggression.
Unfortunately fluoxymesterone is accompanied with a reduction of the globulin that binds to the thyroid, which causes lower T3. Meanwhile the T4 index is totally unchanged, which implies that thyroid function does not change. Remember, many anabolic steroids (notably Trenbolone) lower your T3 levels.
Additionally, while administering fluoxymesterone, PRL levels tend to remain the same.
You can safely take up to 20mg/day of Halotestin in terms of the suppression of endogenous hormones.
Is Halotestin really a steroid?
Either way, Halotestin is a steroid derived from testosterone and posses a 11-beta group that inhibits aromatization.
But it is particularly prone to be reduced to 5-alpha and can cause side effects associated with DHT, such as acne and hair loss. It is normally possible to detect Halo in an adult male’s urine at least 5 days after a single 10mg oral dose.
However the IOC developed a test for metabolites of fluoxymesterone that can detect Halo up to 2 months after it was last taken. Halotestin is not very sought after in bodybuilding, except for right before a competition. It’s more likely to be found in circulation in athletic sports circles, where it is more commonly used in cycles.
