Substance: Fluoxymesterone

Pack: 10mg/30tablets


Innovagen Ultadren aka Halotestin (Fluoxymesterone) is a tableted androgen, which exerts an intense anabolic effect. As for its structure, fluoxymesterone is a derivative of testosterone. It has a difference in structure from the original androgen as it contains some additional groups: 17-alpha-methyl, 11-beta-hydroxy and 9-fluorene group. That is why, this oral steroid has significant androgenic activity, its chemical formula is 9a-fluorene-11b,17b-dihydroxy-17a-methyl-4-androstene 3-on.

Innovagen Ultadren – is a testosterone derivative, so it has some similar qualities. Much more important is that fluoxymesterone is a good basis for 5-alpha reductase enzymes. This fact is confirmed by a large number of disintegration products of the drug.

They are androgens but without 5-alpha group in the structure of their molecules and they are also associated with its outer androgenic nature. This explains the fact that fluoxymesterone turns in more powerful steroid in the body tissues which are sensitive to the action of androgens, to be more precise, in the skin of the head and the whole body, including the prostate. 11-beta hydroxyl group in the molecular structure of fluoxymesterone affects slowing of the aromatization process and it becomes a reason why the production of estrogen becomes impossible.

Historical reference

Fluoxymesterone was described for the first time in 1956. During the tests that were carried out the same year had proven that anabolic activity of the drug was 20 times higher than that of methyltestosterone. It was available on the U.S. market under the names of Halotestin (by Upjohn company).

From the very beginning, the drug was described as halogenated derivative of testosterone, which potential was 5 times greater than of methyltestosterone. Before that the drug was administered as a treatment for burns, fractures, dystrophy, as well as for the effects of corticoid treatment. In the mid-1970s, the control over the drugs increased and fluoxymesterone was used only for the treatment of androgen deficiency and inoperable breast cancer. Nowadays doctors dispute about fluoxymesterone since today they want to prescribe only those medication that do not have risk to harm health. Regardless of all these facts, Innovagen Ultadren is available on the market.

Pharmacological effect

Fluoxymesterone exerts significant androgenic action (exerts a stimulating effect on the development and function of the external genitalia, prostate, seminal vesicles, and the secondary sexual characteristics in males), due to this fact it is often taken for treatment of delayed puberty.

Sometimes it is used to treat specific forms of breast cancer (exerts antitumor activity in tumors of breast cancer in women), as well as for the treatment of severe lack of androgens. It exerts an anabolic effect, which is manifested in the stimulation of protein synthesis, reduce of fat deposition, retention in the body of necessary for protein synthesis potassium, phosphorus, sulfur, for enhancing of calcium fixation in bones, and increasing muscle mass (increased DNA and RNA synthesis, as well as structural proteins, activation of tissue respiration enzymes, ATP synthesis and accumulation of makroergs in the cell).

Use of Innovagen Ultadren

Administration (for men)

Athletes administer Fluoxymesterone at a dose of 5 mg to 40 mg daily during 2-4-6 weeks. Due to its specific features it is well known drug in many sports: martial arts, athletics, hockey, power sports, etc. If you need to increase mass, you may combine Innovagen Ultadren with testosterone, including nandrolone.

Innovagen Ultadren Side Effects

Fluoxymesterone is referred to androgens and thus it may cause androgenic side effects (e.g., increased greasiness of the skin, acne, hair growth on the body and face, sodium and water retention, edema, symptoms of hypercalcemia, thrombophlebitis).

Moreover, the risk of headache, depression, aggression, anxiety, insomnia, paresthesia is high.  These side effects may be caused by high doses. Anabolic steroids can lead to hair loss of male type. Women should remember about the possible virilizing effects of AAS (they are: deepening of the voice, irregular periods, change in skin texture, facial hair growth, and clitoral enlargement, bleeding from the birth canal).

Innovagen Ultadren is fermented by 5-alpha reductase. Most of its metabolites are reduced by 5-alpha. It means that this steroid turns into more active substances in the skin, the head skin and the prostate (prostatic growth). Its relative androgenity can be reduced by taking of finasteride or dutasteride.
