About PeptidesGrid
PeptidesGrid helps people who buy research peptides compare stores on the things that matter: what a milligram actually costs, what published lab tests found, whether a website really belongs to the business it claims to be, and what other buyers experienced.
What we do
We read the product feeds of 41 stores and the product pages of 27 more twice a day, except where a store's site has stopped our reader (its page then says so), and convert every listing to dollars per milligram, so a single vial and a 10-vial kit compare directly. Each page shows when its prices were read. Next to each price we show the vendor's lab score from Finnrick Analytics, with a link to its source. Finnrick is a US testing service that has samples from public submissions and its own purchases tested by third-party labs. We tie each store domain to the vendor that runs it where we can, so a lab score only appears next to that vendor's own prices. Buyers can post experiences and scam reports with evidence, and stores can respond or dispute.
What we don't do
We don't sell peptides, take orders, or give medical advice. We don't test products ourselves. The products on this site are sold by third-party vendors as research chemicals, and nothing here suggests they are safe, legal where you live, or suitable for human use.
Who pays for it
PeptidesGrid is run from Ontario, Canada, and its operator pays for it. The site has no income: no ads, no affiliate links, no paid listings, rankings or removals. We earn nothing when you click through to a store.
How we stay fair
Tables sort by the numbers they show, such as price, lab score or number of listings. Vendors with a Finnrick profile come first on the home grid. No store can pay to change the order. Buyer reports are moderated to the same standard for every store, and every store can respond. Warnings about a store always name their source and the date we checked it. The full method, including how we correct mistakes, is on the method page.
