Direct answer

Is Peptide Pro legit?

Peptide Pro is a research supplier with a substantial vendor-named laboratory record: 83 of 99 supported-compound report sets match their issuers in full. It earns 9/10 overall. Price rows link reports only when the compound, nominal amount and formulation match; the review preserves underfilled batches, lower-purity results and report-specific discrepancies. Its strict exclusion of discounted and coupon orders from returns or replacements matters when deciding whether to order.

Evidence summary

Peptide Pro COAs and evidence

Peptide Pro earns 9/10, with a broad vendor-named testing record and positive customer-service history.

Read report-specific results and the strict discounted-order returns rule before ordering.

Testing and exact certificate coverage

The 99 supported-compound report sets contain 168 retained pages. Eighty-three complete sets match their issuing laboratory records; five more chemistry reports match but retain supplemental endotoxin pages with unresolved issuer lookups. Five other reports have unresolved issuer lookups, five are MZ Biolabs documents without a public verifier, and one BioViridian report has a source-versus-issuer formulation discrepancy. Numerical purity spans 94.73%–99.97% across 91 reports, with three below 98%. Thirty-nine report sets include endotoxin results; none establishes heavy-metal or culture-based sterility testing.

Results worth reading

Results vary by batch. A CJC-1295 with DAC report gives 94.73% purity, a Kisspeptin-10 report gives 97.39% and 3.5 mg against a 5 mg label, and a Hexarelin report gives 97.749%. Two MOTS-c 10 mg reports share printed lot MOTS-110125: November 2, 2025 reports 11.22 mg, while December 8 reports 7.71 mg. A GHK-Cu capsule report prints 50.37 mcg against a 50 mg label in both source and issuer copies; that unit discrepancy is preserved. The Follistatin source says capsule while the issuer copy says lyophilized powder. These last two records remain in the library with their specific findings and do not attach to price rows.
