Simms Research is a research peptide supplier listed in the PepLookup directory, operating from United States and established in 2026. We currently track 34 listings from Simms Research across 24 compounds, and 34 of them were in stock when their prices were last checked. Every price is read from Simms Research'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 supplier. 34 listings link to a certificate of analysis, which you can open from the listing itself. PepLookup does not sell Simms Research's products: every order is placed on the supplier's own site, and everything listed is sold for laboratory research use only.
Highlights
Researchers who shortlist Simms Research tend to weigh a few concrete, checkable points, and this page gathers them in one place. The catalogue covers 24 compounds, each priced per milligram. An active 10% code, PEPLOOKUP, is shown alongside the prices. COAs are linked on 34 listings. Payment options include Visa, Mastercard and American Express. Prices carry the time they were last seen, and out-of-stock listings never win a comparison. None of this is an endorsement: compare cost per mg, read the COA for the exact batch, and confirm terms on Simms Research's site before ordering.
Comparison
Of the 24 compounds Simms Research has in stock that other tracked suppliers also carry, Simms Research had the lowest listed cost per mg on 0. PepLookup tracks 91 other suppliers with listed prices, and every ranking uses cost per milligram rather than headline price, because pack sizes differ. Out-of-stock listings are excluded before ranking. Prices move often, so open any compound's comparison page to see where Simms Research sits against every other supplier today.
