Evidence boundary	Boldenone undecylenate is classified here as Veterinary anabolic-androgenic steroid. Veterinary product history and doping detection do not establish human therapeutic benefit. No FDA-approved human medicine was identified; 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.	1-Testosterone cypionate / Dihydroboldenone is classified here as Synthetic anabolic-androgenic steroid; not testosterone cypionate. Human therapeutic evidence is sparse and catalogue formulations are not authenticated. No FDA-approved human product was identified; anabolic agents are 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.

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.
