Anabolic Steroid Chemistry: Molecular Profiles & Pharmacokinetics
A deep-science reference for understanding the chemistry behind anabolic-androgenic steroids — from molecular structure to receptor binding kinetics and pharmacokinetic properties.
Anabolic-to-Androgenic Ratio (AA Ratio) — The scale from 1:1 (Testosterone) to extremes like Trenbolone (500:500) and Anavar (322–630:24)
Esterification Chemistry — How attaching an ester chain changes lipophilicity, release rate, and half-life
Aromatization Pathways — Which compounds convert to estrogen via the aromatase enzyme and at what rates
5-Alpha Reduction — DHT conversion, androgenic potency in skin/prostate/hair follicles, and why finasteride doesn’t protect against all androgens
C17-Alpha Alkylation — The chemical modification that makes oral steroids hepatotoxic

Are SARMs just a ‘safer’ version of steroids, or is there more to the story? As performance-enhancing compounds continue to evolve, the debate between Selective Androgen Receptor Modulators (SARMs) and traditional anabolic steroids is more prevalent than ever in fitness, bodybuilding, and athletic communities. While both classes of compounds are frequently utilized to accelerate muscle … Read more
At first glance, the butter in your kitchen, the cholesterol in your bloodstream, and the waxy coating on an apple leaf seem to have nothing in common. Yet biochemists classify all three—fats (triglycerides), steroids, and waxes—under a single molecular family: lipids. The thread that binds them is not a shared backbone or functional group, but … Read more
