Costed them per mg against three other suppliers on the same tirzepatide 15 mg spec. Competitive on price and clearly ahead on documentation.

What the room says
Inland operation, which shows up as slightly longer dispatch and slightly cheaper pricing. Results in the log are good and stable. The one recurring complaint is that a warm inland summer transit leg has ruined at least two members' cold packs.

Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
milos_a★★★★★2025-07-16
Queried the related-substances total on lot MKM-25-190; they came back with method, column and detection limit. That depth is rare.
joran_l★★★★☆2026-04-20
Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.
yusuf_a★★★★☆2026-02-14
Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.
georgi_b★★★★★2025-09-08
Arrived on day 3 against a quoted 4. Customs paperwork was right first time, which is why it moved that fast.
jarno_s★★★★★2026-03-07
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
liv_k★★★★★2026-03-21
Reordered on the strength of the last one and got an identical result. Repeatability is the product.
noor_d★★★★★2026-01-20
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
halima_f★★★★☆2026-06-11
Consistent rather than flashy. Everything lands in the high nineties, and it lands there every time.
piotr_n★★★★★2025-02-16
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
thandi_k★★★★☆2026-02-28
Documentation is complete and the numbers are steady. A dependable choice for routine work.
ravi_o★★★★★2025-09-27
Certificate claimed 99.6% on lot MKM-26-314. PeptideMeter came back 99.6%. On an independent column that is as close to agreement as this gets.
ismael_b★★★★★2025-08-14
First order, deliberately small, tirzepatide 15 mg only. Documentation, transit and a VendorInvestigate result at 98.6% all checked out, so the next one will not be small.
bence_v★★★★☆2026-01-07
Everything about the order was routine in the best sense — quoted 4 days, arrived in 3.
nils_d★★★★★2026-02-12
Cold pack was still hard on arrival in Hamburg on day 2. My logger never went above 8°C across the whole run.
dilara_r★★★★★2026-02-16
Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.
sofia_p★★★★★2026-04-02
Quoted 4 days, arrived in 3. Tracking updated at every hop from dispatch to door.
naomi_h★★★★★2026-05-08
The certificate for lot MKM-25-319 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
nabila_m★★★★★2025-09-06
Their warehouse in Australia carries the lines I reorder, so there is no wait on a factory run. Day 3 every time.
kian_b★★★★★2025-03-21
Tenth order from them, all semaglutide 10 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.
marta_m★★★★★2025-07-23
Ordered on a Monday from their warehouse in the Netherlands and it was here by day 3. That is the whole case for regional stock.
dario_p★★★★★2026-02-27
Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.
ilias_t★★★★★2026-03-17
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
fatima_m★★★★★2025-02-23
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
piotr_o★★★★★2026-05-17
Dispatched from their warehouse in Canada rather than from the factory, so the tirzepatide 10 mg was with me on day 4.

Where MKM sells
Xi'an Mokemei Biotechnology Co., Ltd. sells from its own storefront. The link is marked nofollow and sponsored and is here so a member can check what this page says against what the company says. The room is paid nothing for it and a link is not a recommendation.
Visit MKM at mokemeibiotechnology.com →
Whatever the storefront says, check the lot on the vial against the lot on the certificate before you use anything.
Fairness note
Criticism on this page is specific and evidenced. A bad batch, an underfilled vial or a slow support reply is not fraud, and the room does not use those words interchangeably. Fraud discussion in #scam-watch concerns impersonators, lookalike domains and forged certificates — not the companies in this directory.
