A buyer says two PeptiAtlas vials tested as pure filler, and a separate poster reports verifying that its certificate of analysis is fake.

A peptide seller with slick packaging, flagged on a wholesale-sourcing thread.

Where it trips our checks

• Substantiated reports: a buyer who tested two vials reports they were "just filler," despite "legit, nice packaging." A product that tests as filler is the core of a counterfeit-peptide scam.
• COA traceability: a separate poster says "the COA is fake, I verified it."
• Batch testing: the only test on record contradicts the label, showing no active peptide.
• Independent feedback: what public feedback exists is negative, with "no, just no" warnings and no first-hand positives.

Sources

• The reader who flagged PeptiAtlas quoted a buyer: tested two vials, just filler, nice packaging.
• A wholesale-sourcing thread where a commenter reports verifying the COA as fake.
• Cross-check: a logged-in Reddit sweep found no first-hand positive reports.

Bottom line: Documented risk on limited evidence, one filler test plus a verified-fake COA and no positive reports; a named lab result would harden it. Treat with caution.
