Documentation
Every TB-500 lot ships with a batch document pack for the production lot.
COA, HPLC chromatogram, MS identity confirmation, water content and storage notes. Buyer track and destination confirmed before invoicing.
MS identity
Mass spectrometry identity confirmation against the TB-500 reference profile.
Lot traceability
Lot code printed on vial label and reflected in the document pack. Reorders cite the prior lot for continuity.
FAQ
Common TB-500 questions from B2B buyers.
What is TB-500 and how is it used?
TB-500 is the active fragment of Thymosin Beta-4, studied for cytoskeletal remodeling, cell migration and tissue recovery. Qualified B2B buyers and research organizations source TB-500 alongside BPC-157 in recovery protocols.
Why is TB-500 commonly paired with BPC-157?
The combined repair / regeneration coverage is broader: BPC-157 focuses on angiogenesis and inflammation pathways, TB-500 on actin/cytoskeletal remodeling. Research organizations frequently quote both together.
What is the MOQ?
Sample lots from 1 kit (10 vials); production lots from 200 vials with tier pricing.
Do you ship COA + HPLC + MS with each lot?
Yes. For the applicable lot, Pepti confirms the available document set during RFQ review. Depending on the product and lot, the set can include a Certificate of Analysis showing HPLC purity, MS identity, water content and lot traceability.
Can TB-500 be private-labeled?
Yes. Neutral or branded vial labels, carton design, document packs and lot-code handling are available — see the OEM service path.
