Kalyx Labs opened its store in 2026 and ships from the U.S. We track 40 of its listings across 23 compounds, and 34 were in stock when we last checked prices in September. Buyers who want more than one vial can pick from 1 kit listing. Not everything comes in a vial: it also lists sprays. Rather than a report per product, every listing points to one general COA page run by Kalyx Labs, where you can search for your batch. Kalyx Labs says testing is done by an independent lab. Retatrutide comes in four sizes, from 10 mg up to 60 mg. You'll find Retatrutide, 5-Amino-1MQ, BPC-157, GHK-Cu and Tesamorelin near the top of its range. You can pay with credit card and debit card. Kalyx Labs describes its shipping as 1–2 business days processing; 5–8 business days standard; 2–3 business days expedited; 1 business day overnight/express. PepLookup isn't the seller here: you order on Kalyx Labs' site, and its products are meant for laboratory research only.
Kalyx Labs' prices swing from one compound to the next. At our last check it was below the market median on 12 of the 22 compounds we could compare. Retatrutide is the one to watch, at about 60% under the median. Checkout is limited to credit card and debit card. Dispatch terms: 1–2 business days processing. Entering adamdan saves 25%.
Against other sellers, Kalyx Labs lands somewhere in the middle. Its strongest prices were on Retatrutide (about 60% under the median), NAD+ (about 23% under the median) and TB-500 (about 19% under the median). Shop elsewhere for 5-Amino-1MQ, Semax and Ipamorelin, where it ranked 29 of 48, 64 of 69 and 52 of 62. Prices change often, so check each compound against the 84 other suppliers we track before you buy.
