17-Methyltestosterone Description:

 

1. Methyltestosterone is an orally available form of the primary male androgen testosterone. Looking at the structure of this steroid, we see it is basically just testosterone with an added methyl group at the c-17 alpha position (a c-17 alpha alkylated substance), which allows for oral administration. The action of this steroid is moderately anabolic and androgenic, with high estrogenic activity due to its aromatization to 17-alpha methyl estradiol.

2. Methyltestosterone is a very crude synthetic derivative of testosterone.Methyltestosterone has a short half-life, about 2.5 hours, and because of this, the drug needs to be taken frequently to have any real effect on muscle anabolism.

3. Methyltestosterone is converted by aromatase to the long-lived estrogen, methylestradiol. However, methyltestosterone is a fairly potent inhibitor of the aromatase enzyme, so, with continued use, estrogenicity peaks and then decreases, however, when methyltestosterone is stopped, there can be a rebound estrogenic effect.

4. The binding affinity of methyltestosterone is about equal to that of testosterone, however, the longer plasma half-life and the conversion to methylDHT result in a drug that has an anabolic to androgenic ratio of about 1 to 13,Methyltestosterone has been shown in the scientific literature to be a direct antagonist of the glucocorticoid receptor.
