I. Fluoxymesterone (Halotestin) powder basic characters:

Product name: Fluoxymesterone / Halotestin powder CAS number: 76-43-7 Molecular formula: C20H29FO3 Molecular weight: 336.4 Fusion point: 265 ℃ Color: White powder Storage Temp.: RT

What is Fluoxymesterone / Halotestin powder?

Fluoxymesterone is a man-made form of testosterone, a natural sex hormone that is produced in a man's testicles. Small amounts of testosterone are also produced in a woman's ovaries and adrenal system.

The Fluoxymesterone brand name is Halotestin. Halotestin is a synthetic androgen, or male hormone, similar to testosterone. Fluoxymesterone works by binding to androgen receptors, this causes it to interact with the parts of the cell involved in the production of proteins. It can cause an increase in the synthesis of some proteins or a decrease in the synthesis of others. These proteins have a variety of effects, including stopping the growth of certain types of breast cancer cells, stimulating the cells that cause male sex characteristics, and stimulating the production of red blood cells.

Fluoxymesterone is a white or almost white, odorless crystalline powder that dissolves at about 240 ℃, with some decomposition. It is practically insoluble in water, slightly soluble in alcohol and slightly soluble in chloroform.

The chemical name of fluoxymesterone is androst-4-en-3-one, 9-fluoro-11,17-dihydroxy-17-methyl-, (11β, 17β) -. The molecular formula is C20H29FO3 and the molecular weight 336.45.

How does Fluoxymesterone / Halotestin powder work?

Hormones are chemicals produced by the body's glands, which enter the bloodstream and cause effects in other tissues. For example, the hormone testosterone, produced in the testicles, is responsible for male characteristics such as deepening of the voice and increased body hair. The use of hormone therapy to treat cancer is based on the observation that receptors for specific hormones necessary for cell growth are found on the surface of some cancer cells. Hormone therapy can work by stopping the production of a certain hormone, blocking hormone receptors, or substituting chemically similar agents for the active hormone, which cannot be used by the cancer cell. The different types of hormone therapies are classified according to their function and / or the type of hormone involved.

Fluoxymesterone is classified as an androgen. Androgens are hormones such as testosterone and androsterone that produce or stimulate the development of male characteristics. In women, these hormones can be converted into estrogen. Androgens as a cancer therapy are used to counteract the activity of estrogen, thus slowing the growth of the cancer.

Is Anabolic Steroid Fluoxymesterone / Halotestin?

Also commonly known as Fluoxymesterone, Halotestin is an androgenic anabolic steroid that can be taken orally by bodybuilders to encourage lean muscle gains. In the bodybuilding market, it comes in three sizes – 2mg, 5mg and 10mg – and contains a range of inactive ingredients including calcium stearate, corn starch, lactose, sorbic acid and tragacanth.

Halo is an extremely strong and powerful analogue anabolic steroid, possessing an anabolic strength 19 times the strength of testosterone and an androgenic strength 8.5 times the strength of testosterone. However, it was also made clear that it was determined to possess slightly less anabolic strength in humans in practical terms. Athletes and bodybuilders should enjoy a great increase in strength, lean muscle growth, and an increase in definition. The increase in size was purported to be modest but not extreme.

What does the Fluoxymesterone / Halotestin steroid do?

In the use of medical treatment

Halotestin is the trade name of fluoxymesterone, synthesized in the 1950s by Upjohn, and later also produced by Ciba Pharmaceuticals under the name of Ultandren.

Initially marketed for the treatment of clinical problems, such as muscle loss, malnutrition, androgen deficiency problems, fracture healing and general tissue repair, it was also used in conjunction with other drugs that may have some side effect of this nature, such as corticosteroids.

In women and, of course, in very controlled doses, it has been used as an adjunct in the treatment of breast cancer, menopause and outros problems.

In the use of bodybuilding

In the world of bodybuilding Halotestin is considered a very popular choice for power lifters and strength athletes, however, it is also a great hardener and cutting edge steroid for bodybuilders, although the side effects can make the benefits counterproductive. The possible benefits and effects of Halotestin in the use of buildings are:

1) Strength and Energy

Significantly improved strength is the most important and desired effect of Halotestin and often the only reason a bodybuilder will choose to use it.The huge increase in strength and energy comes mainly from Halotestin's effect on red blood cell function. This increased strength will help any athlete push performance to new heights, but with it it increases overall aggression and this often makes it useful for powerlifters, fighters and others where aggressive strength might be a desirable trait.

2) Fat Loss

While not a specific fat loss steroid or one with very potent effects in this area, it can still contribute to fat loss, but these effects will only really be noticed if you are already very thin. Those who haven't already lost a significant amount of body fat during the previous cutting phases are unlikely to notice Halotestin's fat loss effects.

3) Aggression and driving

While this is often considered a negative side effect, increased aggression is also seen as a benefit by specific Halotestin users, particularly those who require the extra push and energy for certain activities such as fighting and powerlifting. As long as this increased aggression is used in a positive way, it is not seen as a problem by Halotestin users.

However, those who are particularly prone to existing mood or anger problems should pay attention to the fact that this trait can worsen those tendencies that exist in other aspects of life outside the competitive arena in which it is valued. Starting Halotestin at a low dose for new users will allow you to monitor its effects on aggression levels and how well you cope with it. The doses can then be changed from there as needed.

4) Pre-race

One of the few uses of Halotestin is during the pre-contest phase where the diet is extremely restricted and strict and where many people will struggle or fall before the last hurdle.Halotestin can provide the extra kick and energy needed to get through the toughest moments just before a match.

Competitors will also benefit from improved physical conditioning prior to a competition with definition and toughness that will receive a boost. This is only of great benefit to those who are already very thin with some of the lowest body fat levels if you want to see the true power of Halotestin in this area. For the average bodybuilder this will not be possible, but those who take physical conditioning to the highest level will appreciate what Halotestin can contribute to this stage of race preparation.

Fluoxymesterone / Halotestin powder dosage

For an increase in performance, doses between 10 mg and 40 mg per day are sufficient. With 10mg you can already get really different effects. However, for aesthetic purposes, especially extreme ones, this use must be slightly higher, reaching around 40 mg per day.

This is an oral steroid and it is recommended to take it on an empty stomach to improve its bioavailability.

Having a half-life of 6-8 hours, 3-4 daily doses of the total dose are needed, i.e. if you choose to use 40 mg per day, you can take 10 mg every 6 hours.

If this is your first time using alotestin, you can start with doses ranging from 5mg to 20mg per day to realize the effects of the anabolic on your body and your individual tolerance levels as well.

If you are preparing to undergo some kind of doping test, it is worth considering that fluoxymesterone can be detected up to 2 months after its use has ended, that is, be careful!

Halotestin vs Nandrolone Deconate

Although both are androgenic anabolic steroids with a similar chemical structure and a common goal of increasing testosterone levels, research suggests that nandrolone is potentially used to heal joints. It is used as a potential treatment for rotator cuff injuries.

It has also been shown that nandrolone's main target of action is skeletal muscle. Activates growth, which in turn minimizes the risk of developing metabolic syndrome.

Halotestin versus Trenbolone

Perhaps Trenbolone is one of the most potent steroids available on the market.

Trenbolone is used to increase appetite and muscle growth. Trenbolone works by increasing the uptake of glucose by the muscles. This results in optimal muscle growth leading to more lean muscle mass.

Liver toxicity is one of the common side effects of both androgenic anabolic steroids.

Halotestin versus Dianabol

Both steroids work in a similar way as they enhance muscle growth, improve testosterone levels and burn fat.

Although Halotestin and Dianabol work by improving nitrogen balance, Dianabol aromatizes to estrogen, causing many unwanted side effects.

What are the side effects of Fluoxymesterone / Halotestin powder?

As with all anabolic steroids, fluoxymesterone is extremely hepatotoxic (toxic to the liver) when taken in too high a dosage. Misuse / abuse of this hormone can trigger: heart disease, stroke, liver disease, mental / mood swings, and increased addiction / substance abuse. Hell, misuse can cause withdrawal symptoms – depression, irritability, and fatigue – for weeks / months after quitting.

But that is not all…

It can also cause all of the following, even if you are careful and behave yourself!

Nausea and vomit


Oily skin / acne

Baldness / hair loss

Increase / decrease in libido (loss / increase in sexual desire)

Skin discolouration (cholestatic jaundice)

Changes in liver function



Increased aggression / roid anger

Menstrual problems (in women)

Virilization (women) – deepening of the voice, excess body hair and clitoral enlargement (this is not always reversible once you stop – thanks but no thanks).


Erectile dysfunction

Painful / prolonged erections – 4 hours or more (rare)

Water retention – excess body water can increase the risk of heart failure (NOTE: look for signs of fatigue, swollen hands / ankles / feet and shortness of breath while lying down)

Hypersensitivity (skin)

Decrease in blood glucose levels (in diabetic patients due to its metabolic effects)

Decreased serum T4 levels and increased resin absorption of T3 and T4 (thyroid hormones), although there is no evidence of thyroid dysfunction.

Breast swelling

Problems urinating

Difficulty sleeping / snoring

Decreased sperm production / decreased male fertility

If you are experiencing persistent stomach pain / nausea, unusual tiredness, yellowing of the eyes and dark urine, then you should speak to your doctor immediately. Likewise, although it's rare to have a severe allergic reaction, if you see a rash, swelling (of the face, tongue, and throat), feel dizzy, or have difficulty breathing, then see a doctor right away.
