TB-500 10mg
Every TB-500 10mg lot ANKR Lab has released, with the independent lab report for each one. Match the lot number on the vial label to the table below. Laboratory research use only.
Each released lot for this compound and the third-party certificate issued for it. Lots that did not pass are never released and never appear here.

A TB-500 10mg certificate of analysis from ANKR Lab reports two things about one specific lot. Purity is measured by RP-HPLC: the sample is separated by chromatography and the share attributed to the target compound is reported as a percentage. Identity is confirmed by RP-HPLC, which compares the measured mass of the sample against the expected mass for TB-500 10mg. The certificate also carries the lot number, the date the lot was received, and a lab accession code.
Testing is performed by Optiq Health Labs, independent of ANKR Lab. The accession code printed on each certificate can be checked with the lab directly, so the document is verifiable outside this website.
TB-500 as certified here is synthetic thymosin beta-4, a 43-residue peptide with a molecular weight around 4,963 g/mol. That puts it in a different analytical bracket from the short peptides in the catalogue. At this length the impurities that matter are usually deletion sequences: chains missing one or more residues from a failed coupling step during synthesis.
Deletion sequences can sit very close to the target on an HPLC trace, because a single missing residue barely shifts retention time. Mass spectrometry is what separates them, since a deletion sequence differs from the target by the exact mass of the missing residue. This is a compound where the LC-MS line on the certificate is doing more work than the HPLC line.
A longer walkthrough, with a sample certificate marked up line by line, is in How to read a peptide certificate of analysis.
Yes. Each TB-500 10mg lot ANKR Lab releases is sent to an independent laboratory for purity (RP-HPLC) and identity (RP-HPLC) testing, and only lots with a passing certificate are released. This page lists every released lot with its certificate. Laboratory research use only.
Testing is performed by Optiq Health Labs, a third-party laboratory independent of ANKR Lab. Each certificate carries an accession code that can be checked with the lab directly.
Every ANKR vial label carries a lot number. Find that lot number in the table on this page, open the lot page or the PDF, and confirm the batch ID on the certificate matches the label.
Purity is the percentage of the sample that the RP-HPLC analysis attributes to the target compound. Identity is confirmed separately by RP-HPLC, which checks the measured mass against the expected mass for TB-500 10mg. These are analytical results for laboratory research use only, not statements about use.
