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
MKM Biolabs lists in GBP. We compared 21 of its 26 listings with the median price per mg across the other stores that list the same peptide in GBP and serve the UK (43 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 26% below that market median. Behind that: 16 products priced below most stores, 5 within 5% of the median, and 0 products priced above most stores.
Priced below most stores (16)
| Product | Price | vs market median |
|---|---|---|
| Retatrutide 40 mg | £85.99 | 49% below |
| MOTS-c 40 mg | £46.99 | 49% below |
| Tirzepatide 60 mg | £92.99 | 47% below |
| Retatrutide 30 mg | £69.99 | 45% below |
| Retatrutide 20 mg | £49.99 | 41% below |
| DSIP 10 mg | £19.99 | 37% below |
And 10 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.
