Is NorthPeptide legit? What we can check
No website can promise that a supplier is trustworthy. These are the checks we can make from public records, the supplier’s own website and our reviews. They are the same checks as in our guide to spotting an unreliable supplier.
Website history (Not known)
Domain first seen less than a year ago. Most peptide stores are new, so PepFinder does not count this against a store.

Independent testing (Not known)
NorthPeptide states that its products are independently tested, links a certificates-of-analysis or lab-results page, names Janoshik, Kovera, Freedom Diagnostics. PepFinder has not yet collected or reviewed any of its certificates, so this is the supplier's own claim.

None found in our records.

How PepFinder rates suppliers
What the rating and the customer rating each measure
The PepFinder rating (out of 10) is our own assessment of a supplier across reliability, product selection, pricing, delivery, customer service, website, payment options, packaging and how much information the supplier makes available. Each part is scored from what we can observe on its website, from public records and from customer reviews; parts we cannot observe are left unscored rather than marked down, and the rating is only shown once enough of them are known. It can move as more of the inputs become available.
The customer rating (out of 5 stars) is simply the average of approved customer reviews, shown from three reviews. Reviews are moderated before publication and suppliers can reply but not remove them.
The price comparison puts each listing's price per milligram against the median across every tracked supplier listing the same peptide in the same currency and serving the same region, so a UK store is measured against stores a UK buyer could order from. Prices are never converted between currencies. Suppliers cannot pay to change any of this; claiming or verifying a profile does not change the rating either.
