MKM — member reviews
96% from 717 member reports. 26 are published in full below; the rating aggregates all of them. Reviews without an order date or a testable claim are not counted.
This community's number, not a fleet-wide one. Independent groups scoring the same vendor land within a few tenths of each other, and where they diverge it is usually because one group weights logistics and another weights purity consistency.
Sixth order from them, all retatrutide 5 mg. Sent one vial from each to VendorInvestigate and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
Documentation is complete and the numbers are steady. A dependable choice for routine work.
Solid on the TB-500 5 mg. Purity where it should be, transit 3 days, paperwork in order.
Held locally in the United States, so the cagrilintide 5 mg arrived on day 3 without an import step.
One of the few places that will quote NAD+ 500 mg at all, and the synthesis came back clean on an independent check.
Moved here after two bad lots elsewhere. 8 orders in and the PeptideMeter numbers have been flat every single time.
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 7 hours.
Same lot documentation as the factory ships, but out of their warehouse in Canada, so it landed on day 2.
Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
First order, deliberately small, MOTS-c 10 mg only. Documentation, transit and a Janoshik result at 99.4% all checked out, so the next one will not be small.
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
Ordered on a Monday from their warehouse in the United Kingdom and it was here by day 4. That is the whole case for regional stock.
8 lots logged now, purity 97.6 to 97.8%. A band that tight is worth more to me than one spectacular number.
Weighed 6 vials from the semaglutide 5 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
Dispatched from their warehouse in Germany rather than from the factory, so the selank 10 mg was with me on day 3.
Queried the related-substances total on lot MKM-24-922; they came back with method, column and detection limit. That depth is rare.
Pleased to find they hold stock in the United Kingdom. Domestic dispatch, day 2, no customs step at all.
Cold pack was still hard on arrival in Cork on day 4. My logger never went above 4°C across the whole run.
Shipped from their warehouse in the United Kingdom, arrived day 4, documentation complete.
Arrived on day 4 against a quoted 4. Customs paperwork was right first time, which is why it moved that fast.
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.
Reconstituted the retatrutide 5 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
Reordered on the strength of the last one and got an identical result. Repeatability is the product.
What a useful review looks like
Order date, what was ordered, what arrived, how long it took, and whether anything was independently tested. That is it. "Great vendor, fast shipping, A+++" is worth nothing and gets removed; a three-star review explaining precisely what went wrong and how it was handled is worth more than ten five-star ones.
Why the negative ones stay up
A directory of nothing but praise is a marketing brochure. Every source page here carries the disappointing results as prominently as the good ones, and the vendors near the top of the ranking are there because their bad entries are few and old, not because there are none.

A good record predicts your batch. It does not guarantee it, and no storefront can. Check the lot on the vial against the lot on the certificate.
