ZC Labs is a U.S. research peptide supplier that launched in 2026. We track 52 of its listings across 22 compounds, and 46 were in stock at our last check. Most compounds come as a single vial or a 10-vial kit. ZC Labs says it processes orders within 12 to 24 hours and ships by USPS Priority, with delivery in 1 to 3 business days. It ships within the United States only. ZC Labs also says its products are tested by Freedom Diagnostics, an independent lab, but we don't have any of its COAs linked yet, so ask ZC Labs for the report for your batch before you order. PepLookup doesn't sell its products; orders are placed on ZC Labs' own site, for laboratory research use only.
Price is the main reason. At our last check, ZC Labs was below the market median on every one of the 19 compounds we could compare, and it had the single lowest price per mg on 8 of them, including BPC-157, NAD+, retatrutide and 5-Amino-1MQ. It also accepts a long list of payment methods: Visa, Mastercard, American Express, Discover, Zelle, Cash App and crypto. The trade-off is paperwork. Until its COAs are linked here, you'll need to request lab reports directly. Code PEPLOOKUP takes 10% off at checkout.
At our last check, ZC Labs was one of the cheapest of the 84 other suppliers we track. On its lowest-priced compounds, such as retatrutide, 5-Amino-1MQ and NAD+, it costs roughly a quarter to a third of the market median per mg. Where it isn't the cheapest, it is still below the median. Prices change often, so open any compound's comparison page to see today's prices side by side.
