Methyltestosterone(17α-Methyltestosterone)For Bodybuilding CAS:58-18-4
Methyltestosterone, also referred to as 17α-Methyltestosterone, is a synthetic anabolic-androgenic steroid (AAS) derived from testosterone. Known for its powerful anabolic and androgenic effects, it has a rich history in both medical and performance-enhancing contexts. This article offers a detailed exploration of the product, focusing on its composition, features, applications, benefits, recommended dosage, usage cycles, half-life, and post-cycle therapy (PCT).
What Is Methyltestosterone?
Methyltestosterone is a chemically modified version of testosterone, characterized by the addition of a methyl group at the 17th carbon position. This structural alteration enhances its bioavailability, enabling oral administration without significant degradation in the liver. It was first introduced in the 1930s and has since been utilized in various therapeutic settings, including hormone replacement therapy (HRT) and the treatment of androgen deficiency.
In the bodybuilding and athletic communities, Methyltestosterone is valued for its rapid effects in enhancing strength, aggression, and overall performance.

1.Duration
4–6 weeks, starting immediately after the cycle ends.
2.Common PCT Drugs
●Clomid (Clomiphene Citrate): 50–100 mg/day for 4 weeks.
●Nolvadex (Tamoxifen Citrate): 20–40 mg/day for 4 weeks.
●HCG (Human Chorionic Gonadotropin): Used in some cases to stimulate natural testosterone production.
3.Goals of PCT
●Normalize hormone levels.
●Prevent muscle loss.
●Minimize estrogen rebound.
