Overview & IntroductionTestosterone is the primary male sex hormone and the base of nearly all anabolic-androgenic steroids. In medical settings, it is prescribed for testosterone replacement therapy (TRT), while in performance enhancement it is often used to increase muscle mass, strength, and recovery.
History & OriginTestosterone was first isolated and synthesized in the 1930s. It quickly became a cornerstone hormone in endocrinology and later the foundation for anabolic steroid development in both medicine and athletics.
Chemical Profile- • Androgenic–anabolic steroid (AAS)
- • Naturally occurring hormone
- • Available in multiple esters (Enanthate, Cypionate, Propionate)
- • Injectable and topical medical forms
Mechanism of ActionTestosterone binds to androgen receptors in muscle tissue, increasing protein synthesis, nitrogen retention, and red blood cell production. It also converts to estrogen via aromatization, which contributes to both benefits and side effects.
Benefits- • Increased muscle mass
- • Improved strength and power
- • Enhanced recovery
- • Increased libido and energy
- • Improved bone density
Risks & Side Effects- • Suppression of natural testosterone production
- • Estrogen-related side effects
- • Acne and oily skin
- • Hair loss (genetic)
- • Cardiovascular strain
Dosage & Cycle InfoDosage varies widely depending on medical TRT use or non-medical performance enhancement. Cycles typically range from 8–16 weeks, with ester choice affecting injection frequency.
Post Cycle Therapy (PCT)PCT is used after a cycle to help restore natural testosterone production. This commonly involves SERMs and lifestyle recovery strategies.
Legal Status & AvailabilityTestosterone is a controlled substance in many countries. Medical use requires a prescription, while non-medical use may be illegal.
