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
US Peptide Labs lists in USD. We compared 29 of its 30 listings with the median price per mg across the other stores that list the same peptide in USD and serve the US (77 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: 5 products priced below most stores, 1 within 5% of the median, and 23 products 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 (5)
| Product | Price | vs market median |
|---|---|---|
| 5-Amino-1MQ 50mg | US$62.00 | 57% below |
| Epitalon 100mg | US$180.00 | 40% below |
| Wolverine blend 10/10mg | US$85.00 | 34% 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.

In their own words: US Peptide Labs exists for one reason: to give laboratories a source they never have to second-guess. The research peptide market is full of unknowns — vague sourcing, inconsistent documentation, and shipping delays that stall real work. We built US Peptide Labs to be the opposite of all of that: an American supplier organized around transparency, consistency, and speed. Our standard Every compound we list is tied to a specific lot, and the corresponding laboratory documentation is made available for that lot as it is received. We publish what we can verify — identity, purity, and concentration as reported for the batch on hand — and we do not advertise figures a document cannot support. If a lot does not meet the threshold we set for it, it does not go out. Made & shipped in the USA We source and ship entirely from within the United States. Orders are packed discreetly and dispatched with full tracking, so there are no overseas customs holds and no mystery timelines. Why laboratories choose us Lot traceability — every product is tied to an identifiable lot, with documentation provided for that lot. Full format range — vials, nasal sprays, and oral sprays. Hard-to-find compounds — including advanced multi-peptide blends most suppliers do not carry. Responsive support — real people, fast answers, and volume pricing for institutional buyers.

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.
