The BPC-157 TB-500 reference list

The BPC-157 TB-500 reference list below carries every study and source cited across this site, numbered to match the inline markers. The peptide-research citations are peer-reviewed primary studies and reviews; the regulatory entries (marked R1–R4) are FDA pages verified against the live source. Where a finding belongs to a single constituent, that is noted in the study itself — there is no combination study to cite, because none has been published [9]. The full citations appear in the Wolverine blend references register on this page.

  8. Editorial synthesis: no peer-reviewed controlled study has administered BPC-157 and TB-500 in combination or defined a synergy ratio, dose, or endpoint. Basis: the absence of any combination study across the cited BPC-157 and thymosin beta-4 literature, including the 2025 BPC-157 systematic review (ref. 10), which makes no mention of TB-500 or combination use. ↗

  10. Compositional and identity basis for the BPC-157 + TB-500 blend: BPC-157 is a 15-amino-acid pentadecapeptide (GEPPPGKPADDAGLV, ~1419.5 Da); TB-500 is the synthetic Ac-LKKTETQ heptapeptide (~889 Da), residues 17-23 of thymosin beta-4, and most efficacy data attributed to 'TB-500' were generated with full-length thymosin beta-4. The blend has no single CAS/MW and no standardized ratio. Identity of the TB-500 fragment established in Esposito S, et al., Drug Test Anal. 2012 (ref. 7); the actin-binding fragment relationship in Irobi E, et al., EMBO J. 2004 (ref. 3). ↗

  13. Pharmacokinetic and dose-context basis: BPC-157 elimination half-life reported under 30 minutes in a rat/dog PK study, and rodent doses commonly expressed per body weight (frequently ~10 microg/kg; gastric-ulcer cytoprotection at 400-800 ng/kg). Thymosin beta-4 dose-response in a rat embolic-stroke model spanned 2-18 mg/kg intraperitoneal, with 18 mg/kg giving no benefit (non-monotonic). Compiled in the audited Wolverine research corpus (dosage_research_context); thymosin beta-4 stroke dose-response per Morris DC, et al., Neuroscience. ↗
