What is the difference between TB-500 and BPC-157 from a wholesale buyer perspective?

TB-500 refers to the active fragment of Thymosin Beta-4 (residues 17–23), a 43-amino-acid peptide associated with systemic tissue repair and angiogenesis. BPC-157 is a 15-amino-acid stable gastric pentadecapeptide with distinct GI and tissue-healing signaling. Both require lot-specific CoA documentation but use different analytical protocols.

What documentation should accompany each TB-500 API lot?

Each TB-500 lot should include: HPLC CoA with purity ≥99%, mass spectrometry sequence confirmation, endotoxin result (<1 EU/mg), residual solvent analysis per ICH Q3C, SDS, and a supplier chain-of-custody letter identifying the manufacturing facility.

What purity standard does TB-500 API need to meet?

TB-500 API must meet HPLC purity ≥99% for compounding use. Given the peptide's larger size relative to BPC-157, mass spectrometry sequence confirmation is critical to verify correct structure and detect any synthesis byproducts or truncation variants.

How is TB-500 API stored?

Lyophilized TB-500 API should be stored at -20°C, protected from light and moisture. Reconstituted solutions should be refrigerated at 2–8°C and used within 28 days. Follow lot-specific storage instructions on the CoA.

What minimum order quantities are available for TB-500?

TB-500 is available in individual vial configurations (typically 5mg or 10mg) and bulk API formats for high-volume 503A programs. Contact our wholesale team for current vial sizes, pricing tiers, and lead times.

About Wholesale TB-500

Wholesale TB-500 API for Licensed Facilities

TB-500 is a synthetic fragment of the naturally occurring peptide Thymosin Beta-4 — specifically the amino acid sequence Ac-SDKPDMAEIEKFDKSKLKKTETQ — that has gained significant traction in regenerative medicine and sports rehabilitation. Its tissue repair, anti-inflammatory, and angiogenic properties have made it a high-demand compound for licensed clinics, integrative medicine practices, and sports medicine facilities. Wholesale Peptide Distributors supplies TB-500 bulk API manufactured in ISO 5, cGMP-aligned US cleanroom facilities with raw API from FDA green list qualified manufacturers.

For 503A compounding pharmacies preparing TB-500 injectable formulations, Wholesale Peptide Distributors provides bulk API with the full documentation package required by USP Chapter <797> quality programs: HPLC purity report (≥99%), mass spectrometry identity confirmation, endotoxin testing (LAL, <10 EU/mg), residual solvent testing, and chain-of-custody records. TB-500 is available in acetate salt form appropriate for injectable compounding at bulk quantities starting at 1g.

Clinics offering regenerative medicine protocols, musculoskeletal rehabilitation programs, or post-surgical recovery programs frequently source wholesale TB-500 alongside BPC-157 for combination recovery protocols. Finished-dose TB-500 is available for clinic dispensing programs, shipped cold-chain with full CoA documentation. Wholesale Peptide Distributors supports both standalone TB-500 orders and combination wholesale orders with other healing peptides.

Wholesale TB-500 pricing is available by quantity tier. Wholesale Peptide Distributors maintains strong inventory positions in high-demand healing peptides to support consistent clinic and pharmacy reorder cycles. Contact our wholesale team for current availability, SKU specifications, and pricing based on your monthly program volume.
