Batch facts for the TB-500 10mg vial
Lot TB5-260415-A, tested June 2026 by Titreon Analytical: 98.86% purity by HPLC; identity confirmed by LC-MS; net content 10.22 mg in a 10mg vial; certificate COA-2026-2087.
What the published research describes
What it is: A synthetic peptide based on thymosin beta-4, an actin-binding protein involved in cell migration. TB-500 is a fragment of that protein, not the full protein.
Wound models: In a rodent model, thymosin beta-4 accelerated dermal wound healing and increased cell migration into the wound (Malinda et al., J Invest Dermatol 1999, PMID 10469335 https://pubmed.ncbi.nlm.nih.gov/10469335/ ).
Blood vessel growth: Its actin-binding site was shown to promote angiogenesis, the growth of new blood vessels (Philp et al., FASEB J 2003, PMID 14500546 https://pubmed.ncbi.nlm.nih.gov/14500546/ ).
Review: A review frames thymosin beta-4 as a multi-functional regenerative peptide studied across several tissues (Goldstein et al., Expert Opin Biol Ther 2012, PMID 22074294 https://pubmed.ncbi.nlm.nih.gov/22074294/ ).
What is missing: The evidence is dominated by animal models. No controlled human trial establishes a healing outcome or a timeline, and there is no approved TB-500 medicine.
These describe what published studies measured, not a TB-500 protocol or a dose for any person.

How to check a TB-500 vial
Identity by LC-MS says the peptide is TB-500; a purity figure alone only says the sample is mostly one peptide.
Purity is 98.86% by HPLC for lot TB5-260415-A, against a not-less-than 95.0% release criterion.
Net content is 10.22 mg in a 10mg vial, tested by Titreon Analytical in June 2026.
The TB-500 panel also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen.
