Research Peptide Purity Testing for Retatrutide, Tirzepatide, and Related Compounds

We need purity testing on a range of research peptides with a target purity of greater than 99%. Compounds include Retatrutide, Tirzepatide, BPC-157, Semax, TB-500, MOTS-C, NAD+, Tesamorelin, Selank, and a peptide blend containing TB, BPC, KPV, and GHK. Laboratories with capabilities in peptide characterization, purity analysis, and identity verification using methods such as HPLC, UPLC, or LC-MS are encouraged to respond.
