Nandrolone vs Trenbolone

Nandrolone (A-tier) vs Trenbolone (F-tier). mechanism, trials, claims vs data, dosing literature. side-by-side reference.

Nandrolone — tier A

a 19-nor androgen with formulation-specific human PK for decanoate and phenylpropionate, historical US approvals, and a currently authorized Australian decanoate product.

nandrolone has real human depot pharmacokinetics, but each number belongs to a named ester, oil vehicle, volume, site, and study design.

7 to 12 days human decanoate apparent terminal half-life · half-life decanoate apparent terminal half-life 7 to 12 days in humans; phenylpropionate has a different, shorter absorption profile · androgens

Trenbolone — tier F

a 19-nor trienic androgen used currently in cattle, with a French drug-archive record of historical human hexahydrobenzylcarbonate marketing but no modern controlled human therapeutic PK, outcome, or safety program.

trenbolone is pharmacologically active and historically reached a human product, but the current evidence file fails the human PK, outcome, safety, and product-identity gates.

0 modern controlled human therapeutic trials · half-life no measured human half-life; cattle free-parent disappearance about 1.5 hours after intravenous radiolabeled acetate · androgens
