Green Flags Third-party COAs available: The vendor provides certificates of analysis from independent labs, not just in-house testing Named testing labs: COAs reference specific labs (Janoshik, Finnrick, MZ Biolabs) rather than generic "laboratory testing" Batch-specific testing: Each production batch is tested individually, not a single test applied to all inventory Transparent sourcing: The vendor discloses manufacturing origin and synthesis method Research-use certification: Requires buyers to certify research-only intent Red Flags No COAs or "proprietary" testing claims: Any vendor refusing to provide test documentation should be avoided "99% purity guaranteed" without evidence: Blanket purity claims without batch-specific testing are meaningless Health claims or dosing instructions: Vendors making therapeutic claims or providing human dosing guidance are operating outside legal boundaries Unusually low pricing: Peptide synthesis has real costs significantly below-market pricing suggests quality compromises No refund or verification policy: Reputable vendors stand behind their products with testing-based refund policies Our Approach to Quality Verification At PeptideStack, we don't make blanket "purity guaranteed" claims
