FAQ
What's the chemical difference between BPC-157 and TB-500?
BPC-157 (CAS 137525-51-0, MW 1419.53 g/mol) and TB-500 (CAS 77591-33-4, MW 4963 g/mol) are distinct compounds. BPC-157 and TB-500 are the two most-cited research peptides in tissue-signaling literature, frequently studied together (Wolverine Stack) but mechanistically distinct.
Which is more commonly used in research?
Both BPC-157 and TB-500 appear extensively in Tissue-signaling research compounds literature. Comparative-mechanism studies frequently use them as paired references. Selection between them depends on the receptor coverage, kinetics, and assay system of the planned experiment.
What purity does Orion ship for each?
BPC-157 ships at 99.2%. TB-500 ships at 99.1%. Each batch is independently tested by reversed-phase HPLC and confirmed by mass spectrometry against the theoretical molecular weight. Every order ships with a batch-specific Certificate of Analysis.
Are these for human use?
No. All Orion research compounds are for in-vitro laboratory research only. They are not FDA-approved for any therapeutic, diagnostic, or clinical use, and they are not for human consumption.
