Nandrolone vs Boldenone

Nandrolone (A-tier) vs Boldenone (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

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

at a glance

• Nandrolone: tier A · 7 to 12 days human decanoate apparent terminal half-life
• Boldenone: tier F · 123 h median horse terminal half-life, animal-only
