Thymosin Beta-4
The Book of Peptides is not a clinic and not your doctor. We do not sell, prescribe, recommend, or personalize any compound, and no grade or ranking here is an endorsement. In the United States, most of these compounds are not FDA-approved and are sold for laboratory research only; a few are prescription drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful. Nothing here is a recommendation to buy, possess, or self-administer anything. Consult a licensed physician before any decision involving peptide use.
Full-length Thymosin Beta-4 has real trial history under other names and routes – RGN-259 eye drops and RGN-137 topical gel both came from registered RegeneRx human trials. "TB-500" as sold and injected is typically a shorter synthetic fragment with essentially no direct human trial data of its own.
