View COATested by Third-party laboratory
Based in the U.S., Crownwell Research sells peptides for laboratory research and started trading in 2026. In November, Crownwell Research had 38 items across 18 compounds on sale, with nothing out of stock. 8 of those listings are multi-vial kits rather than single vials. Not everything comes in a vial: it also lists sprays. It accepts debit and credit cards, PayPal, Plaid, Cash App, Square and Zelle. Retatrutide comes in four sizes, from 10 mg up to 40 mg. Its stated delivery terms: 1–2 business days processing; orders before 2:00 PM EST typically ship same day; 3–5 business days standard; 2 business days expedited; next-business-day overnight/priority. Rather than a report per product, every listing points to one general COA page run by Crownwell Research, where you can search for your batch. Crownwell Research says testing is done by a third-party lab. Its biggest lines are Retatrutide, Tirzepatide, Bacteriostatic Water, GHK-Cu and MOTS-c. PepLookup isn't the seller here: you order on Crownwell Research's site, and its products are meant for laboratory research only.
Crownwell Research's prices swing from one compound to the next. Roughly 7 in 10 of its comparable compounds beat the median (12 of 18). Nobody we track beat it on MOTS-c (76 sellers). On speed, it promises 1–2 business days processing. Payment is flexible: debit and credit cards, PayPal, Plaid, Cash App and Square. Entering peplookup saves 10%.
Against other sellers, Crownwell Research lands somewhere in the middle. Its strongest prices were on MOTS-c (70% below the typical price), Epitalon (45% below the typical price) and Bacteriostatic Water (40% below the typical price). Its weakest prices were on Semax (20% over the typical price), BPC-157 + TB-500 (16% over the typical price) and Ipamorelin (14% over the typical price). Prices change often, so check each compound against the 84 other suppliers we track before you buy.
