Why does PepFinder say this?
We can show a source for 9 of the 15 facts that matter about a store (who runs it, contact details, shipping, payments, testing, prices). Not yet confirmed: shipping destinations, stated delivery time, payment methods, customer support channels, testing laboratory, public batch numbers. “Not confirmed” means we have not found it, not that the answer is no.

We may earn a commission. How this works
Prices as listed by the supplier when we last checked; the supplier confirms the final price. “vs market” compares price per mg with the median across tracked suppliers listing the same peptide in the same currency and serving this store's region, never converted.
How its prices compare
GB Peptides lists in GBP. We compared 4 of its 13 listings with the median price per mg across the other stores that list the same peptide in GBP and serve the UK (117 to 216 stores per product). Prices are never converted between currencies, so this is a like-for-like comparison for a buyer in the UK.
Taken together, its typical listing sits around 22% below that market median. Behind that: 3 products priced below most stores, 0 within 5% of the median, and 1 product priced above most stores. A store is rarely the cheapest or the dearest on everything, so the product you want matters more than the overall figure.
Priced below most stores (3)
| Product | Price | vs market median |
|---|---|---|
| MOTS-c 40mg | £60.00 | 35% below |
| Retatrutide 60mg Vial | £180.00 | 31% below |
| GHK-Cu 100mg | £40.00 | 13% below |
Priced above most stores (1)
| Product | Price | vs market median |
|---|---|---|
| MOTS-c 10mg | £25.00 | 9% above |
Price per mg lets vials of different sizes be compared. A higher price can reflect a smaller vial, included shipping, or testing the store pays for; the per-peptide price pages show every store side by side. Prices are as the store listed them when we last checked.

Is GB Peptides 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.

Written policies (In place)
Refund policy and terms published.
Independent testing (Not known)
GB Peptides states that its products are independently tested, links a certificates-of-analysis or lab-results page. PepFinder has not yet collected or reviewed any of its certificates, so this is the supplier's own claim.
PepFinder verification (Not known)
Not verified. Most suppliers are not; verification is voluntary.

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.
