Trenbolone vs Boldenone
updated
Trenbolone (tier F): Trenbolone is an anabolic-androgenic steroid. Boldenone (tier F): Boldenone is an anabolic-androgenic steroid.
Trenbolone · tier F
Trenbolone is a 19-nor anabolic-androgenic steroid used underground, usually as an injectable product labeled acetate or enanthate, for muscle, strength, recomposition, and a harder or drier look. Current US approval is only for cattle ear implants.
tier rationale
F grade reflects no controlled human efficacy trial, no measured human plasma half-life, and no current human product. It does not mean trenbolone is biologically weak. The human observational safety signals add concern without establishing a safe or causal exposure-response curve.
Boldenone · tier F
a veterinary boldenone undecylenate horse drug with measured equine oil-depot PK, a small human oral metabolism study of the free parent, and no controlled human therapeutic program.
tier rationale
F tier reflects veterinary-only current authorization, no controlled human therapeutic outcome or safety program, and major product-quality uncertainty. A rigorous animal PK study does not lift the human evidence grade.
