Trenbolone vs Boldenone

Trenbolone (F-tier) vs Boldenone (F-tier). mechanism, trials, evidence boundaries, dosing literature. side-by-side reference.

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.

Trenbolone increased muscle and bone measures and reduced fat in rats. People report using it for muscle, strength, recomposition, and a harder look, but no controlled human study has measured those outcomes or dehydration. The human evidence supports concern, not a quantified physique benefit.

0 controlled human physique trials in the reviewed record · half-life no measured human half-life; cattle free-parent disappearance about 1.5 hours after intravenous radiolabeled acetate · androgens

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.

the horse depot curve is real and useful as animal evidence, but the human treatment file is absent and cannot be reconstructed from urinary metabolites or veterinary labeling.

123 h median horse terminal half-life, animal-only · half-life median 123 hours in horses after intramuscular undecylenate; no measured human depot half-life · androgens
