PEPTIDE VENDORS

 Below is a list of vendors that Peptide Source has evaluated to date. This list grows over time. Any time we evaluate a vendor, we do so objectively with no affiliation unless a vendor is otherwise labeled as a sponsor on our website and/or forum. We select popular items from each vendor’s catalog and purchase them anonymously to experience the process. We send some of these items out for third party lab testing. Any tests we’ve done are located on our forum.
