What you are procuring

TB-500 on this site is a lyophilized research peptide (the synthetic fragment Ac-LKKTETQ). It is sold for in vitro laboratory research. It is not a drug product, not a dietary supplement, and not for human or veterinary use. Investigational literature about this fragment or about full-length thymosin β4 does not change the intended use of this reagent.

If the intended use is anything other than laboratory research, do not order it here.

Lot status: certificate not posted yet

The TB-500 product page currently reads LOT PENDING. Chromatographic purity, content versus label, and identity are listed as certificate pending. There is no public lot number and no assay figures to publish. We do not invent them.

Absence of a lot page on the lot library means the certificate is not posted yet. That is not a pass, a fail, or a hidden result. Treat this SKU as not lot-documented until a record is public.

How to read a certificate when one exists

A Certificate of Analysis is lot-specific. Match the lot on the vial, the lot on the PDF, and the lot on the product page. Read chromatographic purity and content versus label as two different numbers. Guide: How to read a GLP-1 peptide COA.

For a worked example of a published lot on this catalog, see BPC-157 lot 8sprqvs on where to buy BPC-157 for laboratory research and the lot page /coa/bpc-157-8sprqvs/. That assay does not apply to TB-500.
