Halotestin TN Pharma (Halotestin) increases strength and endurance indicators. And in fact, this drug is the number one choice for weightlifters who want to increase their strength. When training before competitions, this drug can also be very useful for relieving the condition and burning fat. This is one of the strongest anabolic androgenic steroids, which is obtained from methyltestosterone with a modified structure in the chemical formula. This steroid has the highest anabolic and androgenic rating – 1900/850. Despite the fact that it has such high anabolic properties, its anabolic properties are considered to be practically zero! It acts more like an androgenic agent.

With long-term use of halotestin, like all 17-alkyd androgens, very serious problems may arise. There is a rather large "bouquet" of possible side effects. Halotestin should not be taken simultaneously with antidiabetic drugs. In combination with nandrolone, primobolan depot, etc. leads to an increase in quality muscle mass.

Steroid profile

  • Anabolic activity – 1900% of testosterone
  • Androgenic activity – 850% of testosterone (very high)
  • Aromatization (conversion to estrogens) – absent
  • Suppression of the hypothalamus-pituitary-testis axis is pronounced
  • Toxicity to the liver is very high
  • Method of administration – inside (tablets)
  • Duration of action – 6-9 hours
  • Detection time – 2 months

Pharmacological properties and effects of Halotestin

Initially, fluoxymesterone was used as a means with pronounced androgenic properties, used in the treatment of male hypogonadism and delayed puberty in men, for the treatment of breast cancer in women. Currently, medicine has refused to use it. Halotestin is about five times more powerful than methyltestosterone.

Halotestin (Fluoxymesterone) is similar in structure to methyltestosterone. It was developed by modifying testosterone in three positions: 17-alpha-methyl group, 11-beta-hydroxy group, and also 9-fluoro group.

The first chemical modification makes it possible to extend the half-life of the drug when taken orally and to level the destructive effect of the first passage through the liver, while keeping the concentration of the active substance in the blood as much as possible.

The second modification is aimed at preventing the enzymatic conversion of the molecule by attaching aromatic rings to it, in other words, the drug does not turn into estrogen. The ability to block estrogen and prolactin receptors is assumed, which excludes the risk of developing gynecomastia, edema and female-type fat deposits.

The last group determines the name of the drug (fluoxymesterone) and is aimed at increasing the androgenic activity of the drug (facilitates the reduction in the 5a position, which leads to the formation of dihydrotestosterone).This is an active form of the drug that circulates in the blood, usually in small quantities, significantly surpasses the activity of testosterone and is capable of firmly binding to androgen receptors in the cells of organs and muscle tissue.

It was also noted that the drug improves aerobic performance athletes in athletics. This is connected with the ability to stimulate erythropoiesis, hemoglobin synthesis. At the same time, a larger number of erythrocytes is able to more efficiently transport oxygen to the cells.

Fluoxymesteron can be used to burn fat, because it was shown that the drug increases the oxidation of fatty acids in fast muscle fibers. Although for these purposes there are also safer and more effective anabolic agents, in particular winstrol, testosterone, oxandrolone.

Admission course

The optimal dose of halotestin is 10 mg/day, it is not recommended to exceed the dose of 20 mg/day. In addition, long-term use of halotestin (more than 6 weeks) may be unsafe for sexual function. Based on the ratio of benefit and harm, conducting a course of halotestin is most expedient only before competitions in order to obtain the two main effects of increasing physical strength and aggression.

Fluoxymesterone practically does not cause the growth of muscle tissue. Combinations of the drug with other anabolic agents also do not have special advantages.

Side effects

Hypertrophy and hyperplasia of the prostate, the development of prostate adenoma and, possibly, an increase in the probability of cancer development are associated with the increased rate of formation of dihydrotestosterone from testosterone.The relatively easy ability of the drug to convert into dihydrotestosterone may in the future have adverse health consequences under long-term use. Fluoxymesteron is estimated to be a drug that is 19 times superior to the anabolic properties of testosterone, and 8.5 times its androgenic properties. Information about the activity of the drug was obtained experimentally.

Halotestin is toxic to the liver. Athletes who have used the drug often report organ enlargement and pain. Studies show that the drug definitely leads to an increase in the levels of liver enzymes, which indicates a steady process of increasing the degradation of liver cells under the influence of fluoxymesterone. This fact is confirmed by literary sources.
