View COALaunched in 2026, Simms Research offers research peptides from the U.S. Its catalogue on PepLookup comes to 34 listings covering 24 compounds; every one of them was in stock during our October price check. On shipping, Simms Research lists same-day dispatch before 5 PM EST; UPS Standard or FedEx 2-Day Express; free FedEx 2-Day on orders over $200. Its listings link to the COA page on Simms Research's own site rather than to a report for each product, so look for your batch there. Retatrutide comes in four sizes, from 10 mg up to 60 mg. Most of its listings are for Retatrutide, Tirzepatide, BPC-157, GHK-Cu and Tesamorelin. It accepts Visa, Mastercard, American Express, Discover, Apple Pay and Google Pay. PepLookup doesn't sell its products; orders go through Simms Research's own site, for laboratory research use only.
Simms Research charges more than most. Only 4 of its 24 comparable compounds beat the median. Wolverine is the one to watch, at about 25% under the median. Payment is flexible: Visa, Mastercard, American Express, Discover and Apple Pay. On speed, it promises same-day dispatch before 5 PM EST. At checkout, PEPLOOKUP knocks 10% off.
Simms Research is at the expensive end of what we track. Where it wins is Wolverine and Retatrutide; Wolverine, for one, was 25% below the typical price. Bacteriostatic Water is where it falls behind, at roughly twice the typical price, with MOTS-c not far off at 84% over the typical price. Compare each compound with 84 other suppliers before you order.
