The majority of compounds documented here are not approved by the FDA for human use. Approved drugs (e.g. semaglutide, tirzepatide) are noted explicitly and require a licensed prescriber.
Many peptides — including BPC-157 and GHK-Cu in injectable form — are sold strictly "for research use only — not for human consumption." Purity, identity, and dosing of such products are not regulated or guaranteed.
Several compounds are banned in competitive sport under the WADA Prohibited List. Athletes risk sanction regardless of intent or formulation.
Always consult a qualified, licensed healthcare professional before considering any compound. Individual risk depends on your full medical context.
