Compare evidence.
Keep the context.
Select 2–3 profiles from the English Library. Class and grade describe evidence and regulatory context, not comparative effectiveness or suitability for an individual.

| Evidence boundary | Nandrolone phenylpropionate is classified here as Shorter-ester anabolic-androgenic steroid. Historical medical reports do not establish safe performance use or equivalence with nandrolone decanoate. No current FDA-approved product was identified in this review; prohibited by WADA at all times. A catalogue name does not establish identity, formulation, quality or authorisation, and this page provides no dosage, mixing, injection or purchasing instructions. | Nandrolone decanoate is classified here as Long-acting anabolic-androgenic steroid with historical medical uses. Bounded medical history does not validate performance use or unverified depot products. A U.S. controlled anabolic steroid; exact current approved-product status must be checked and WADA prohibits it at all times. A catalogue name does not establish identity, formulation, quality or authorisation, and this page provides no dosage, mixing, injection or purchasing instructions. | Testosterone is an endogenous androgen and an active ingredient in authorised prescription medicines, but 'Test' does not identify an ester, formulation, strength, manufacturer or authorisation. Cypionate, enanthate, undecanoate, propionate, no-ester formulations and blends are not automatically interchangeable. TRAVERSE found MACE noninferiority for a specific gel in a defined population while other safety signals remained. This evidence does not authenticate catalogue products or support performance use. WADA 2026 prohibits testosterone and its esters at all times. |

Missing fields mean information is unavailable in the current structured dataset, not that a molecule has no risks or uncertainties. English translations retain the original evidence boundaries. Where translation is not yet verified, the original Thai excerpts remain available under an explicit label. Sources retain their original language.
