About PeptidesGrid

PeptidesGrid helps people who buy research peptides compare stores on the things that matter: what a milligram actually costs, what independent 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 public prices from 67 stores every day and convert every listing to dollars per milligram, so a single vial and a 10-vial kit compare directly. Next to each price we show the store's lab rating from Finnrick, an independent US lab that tests samples customers send in. We check every store domain against the websites Finnrick lists for each vendor and mark lookalikes, mirrors and known fraud sites. 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 or suitable for human use.

How we stay fair

No store pays to be listed, ranked, featured or removed, and there are no affiliate links: we earn nothing when you click through to a store. Tables sort by price and lab rating, nothing else. Community reports are moderated to the same standard for every store, and every store can respond. The full method is on the method page.

Where we are

PeptidesGrid is operated from Ontario, Canada. Corrections, store questions and removal requests go through the contact form; we read every message.
