Overview
GenPeptide holds full certificate-of-analysis coverage: all 33 tracked listings link to a third-party lab document, one of the more complete verification records among suppliers PepLookup tracks. GenPeptide is a research peptide supplier established in 2025, currently listing 22 compounds, with all 33 associated listings in stock at last check. This GenPeptide review is built from prices read directly from the supplier's own product pages and converted to cost per milligram, so a single vial and a multi-vial kit can be compared on the same scale as every other tracked supplier. A public review profile averaging 4.4 out of 5 adds a second, independent signal alongside the COA coverage. An active GenPeptide discount code is applied to the prices shown here. PepLookup does not sell GenPeptide's products: every order is placed directly on the supplier's own site, for laboratory research use only.
Highlights
GenPeptide's combination of full COA coverage and a 4.4-star public rating puts it among the more consistently verified suppliers PepLookup tracks 33 of 33 listings link to a third-party lab certificate, with no gaps. The catalogue covers 22 compounds, each priced per milligram for fair comparison. An active GenPeptide coupon code, peplookup, gives 10% off and is already reflected in prices shown. Payment options include Visa, Mastercard and Discover standard processing, no unusual restrictions. Prices carry the time they were last seen, and out-of-stock listings never win a comparison. Compare cost per mg and confirm current terms on GenPeptide's own site before ordering.
Comparison
Of the 22 compounds GenPeptide carries that overlap with other tracked suppliers, it did not hold the lowest cost per mg on any of them. PepLookup tracks 89 other suppliers, ranking every listing by cost per milligram rather than headline price, since pack sizes differ. GenPeptide's real edge is verification, not price full COA coverage and a strong rating, rather than the cheapest listing. Check the comparison table for where it sits on cost specifically.
