YK-11 vs Oxandrolone
updated
YK-11 (tier F) vs Oxandrolone (tier S): what each is, half-life and source counts side by side.
YK-11 · tier F
YK-11 is a steroidal androgen-receptor research chemical, not a peptide. It is commonly marketed as an oral capsule for muscle and strength, but its human record covers metabolite detection and one doping-control sample, not efficacy or safety.
tier rationale
F tier reflects cell and animal findings without controlled human evidence for muscle gain, strength or safety. The human publications identified concern exposure detection and metabolism.
Oxandrolone · tier S
Anavar is oral oxandrolone, an anabolic-androgenic steroid used in bodybuilding for muscle, strength, and a leaner or harder look.
tier rationale
S grades the certainty of the identity, human PK, and randomized outcome record; it is not a safety or current-approval grade.
