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. None of the compounds covered are approved for the uses described here by the U.S. FDA, Australia's Therapeutic Goods Administration (TGA), New Zealand's Medsafe, or the equivalent regulator in most other countries.
Most are sold for laboratory research only, a few are prescription-only drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful wherever you live. Nothing here is a recommendation to buy, possess, or self-administer anything.

Thymulin is a zinc-dependent thymic nonapeptide (originally isolated as serum thymic factor) that requires equimolar zinc to be biologically active and helps regulate T-cell differentiation, with additional anti-inflammatory and analgesic effects reported in animal models. The evidence base is almost entirely preclinical: rodent studies support immunomodulation and pain modulation, but there are essentially no controlled human efficacy trials for the injectable research form. It is sold as an immune-support research compound and appears in some topical hair formulations, and is distinct from the better-characterized thymic peptides Thymalin and Thymosin Alpha-1.
