How to Spot Peptide Source Red Flags

The clearest red flags of a questionable peptide source are the absence of batch-specific certificates of analysis, vague or unverifiable claims about testing, results that sound too good to be true, no clear way to reach a real person for support, high-pressure discounting that rushes your decision, and product labels that do not match what was advertised. Any one of these is a reason to slow down; several together is a reason to walk away. The reliable pattern is to look for testing you can independently verify, tied to the specific batch you would receive, from a lab you can confirm actually exists. Pepdex does not publicly name or rank vendors, because community sentiment shifts and we will not stand behind a claim we cannot verify. What is public and durable is the vetting method itself, so you can apply these same checks to any source and judge it for yourself.
