Why does PepFinder say this?
We can show a source for 10 of the 15 facts that matter about a store (who runs it, contact details, shipping, payments, testing, prices). Not yet confirmed: shipping destinations, customer support channels, refund or returns policy, testing laboratory, public batch numbers. “Not confirmed” means we have not found it, not that the answer is no. See sources.

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
Peptide Sciences lists in USD. We compared 35 of its 66 listings with the median price per mg across the other stores that list the same peptide in USD and serve the US (7 to 186 stores per product). Prices are never converted between currencies, so this is a like-for-like comparison for a buyer in the US.
Taken together, its typical listing sits 18% above that market median. Behind that: 0 products priced below most stores, 2 within 5% of the median, and 33 products priced above most stores.
Priced above most stores (33)
| Product | Price | vs market median |
|---|---|---|
| Semaglutide 10mg | US$255.00 | 374% above |
| GLOW blend 30mg | US$165.00 | 285% above |
| IGF-1 LR3 100mcg x 10 | US$300.00 | 253% above |
| KLOW blend 80mg | US$395.00 | 243% above |
| NAD+ 750mg | US$300.00 | 208% above |
| IGF-1 LR3 1mg | US$250.00 | 194% above |
And 27 more in the full catalogue below.
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.

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.
