Evidence boundary	Methyl-1-testosterone / M1T is classified here as Synthetic oral anabolic steroid without an approved human indication. No adequate therapeutic evidence base was identified; marketed bodybuilding claims are not clinical evidence. No FDA-approved human drug 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.	Methylstenbolone is classified here as Synthetic oral anabolic steroid without an approved human indication. No adequate therapeutic trial programme was identified; available context is toxicology, case reports and enforcement. No FDA-approved human drug was identified; FDA warns about steroid-like bodybuilding products and WADA prohibits anabolic agents. 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.

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.
