Xi'an Mokemei Biotechnology (revision 18)

Xi'an Mokemei Biotechnology Co., Ltd. (trading as MKM; mokemeibiotechnology.com) is a research-compound supplier trading as MKM from Xi'an, Shaanxi, China, incorporated in 2016, distributing research peptides, SARMs and raw materials with batch documentation.^[1][2]

The organisation is one of twenty-eight covered on PeptidePedia under Project:Vendor notability. Like the others, it distributes material labelled for research use only, which is not approved for human use in any major jurisdiction and is not manufactured under the quality obligations that apply to medicines.^[3]

This article describes what is verifiable. Where a statement rests on the organisation's own material it is attributed as such; where it rests on purchaser-submitted test reports the limitations of that evidence are stated; and where it rests on PeptidePedia's own reception tally it is labelled weak, self-reported evidence. Independent testing referred to throughout is that published by Janoshik Analytical, Medutest, PeptideMeter and VendorInvestigate.^[4]

Incorporated in 2016 in Xi'an, the organisation operates from the largest city in north-western China and, like the Chengdu entity, from outside the coastal manufacturing belt.^[1] Xi'an has a substantial pharmaceutical and botanical-extract sector, and the organisation's catalogue includes extract-derived materials alongside synthetic peptides, which is unusual among the entities covered here.^[2]

The documentary base is the registry record and the organisation's own material, plus purchaser reports. No independent coverage has been identified.

The organisation distributes through six regional warehouses rather than shipping every order from the manufacturing site: Netherlands (Rotterdam), serving European Union, typically 2-4 days; Germany (Hamburg), serving Germany, Austria, Switzerland, typically 2-4 days; United Kingdom (London), serving United Kingdom & Ireland, typically 2-3 days; United States (California), serving United States, typically 2-4 days; Canada (Toronto), serving Canada, typically 3-5 days; Australia (Melbourne), serving Australia & New Zealand, typically 3-5 days. Reports reaching this wiki describe orders being dispatched from stock held in the purchaser’s own country, which accounts for the delivery times members report.

Purchaser reports describe conventional vialled lyophilised material with a batch certificate reporting purity and appearance, and water where the line carries it.^[5] Lot identifiers in the submitted set have corresponded across the vial label, the certificate and the invoice, which is the minimum condition for traceability and the one a purchaser can check without any equipment at all.^[5]

Supplementary documentation — a residual-solvent screen, a second certificate covering an earlier lot, the analytical conditions behind a figure — is issued on request from the organisation's own records, and submissions describing such requests report them met within a working day.^[5]

The extract-derived listings sit in a different analytical world from synthetic peptides: a standardised extract is characterised by marker-compound assay rather than by area percent of a single species, and a purity figure on such a material means something different.^[2]

Submitted reports on MKM material to July 2026 cover the incretin range and a small number of repair peptides. Reported area percent figures have been high across the set, and where an independent report and the accompanying certificate could be placed side by side the two have agreed within the range that different separations account for.^[5]

Where an independent report and a certificate differ slightly, the ordinary explanations are methodological: different columns, different integration parameters, different reference standards, or sample handling between purchase and testing. None of them makes either figure wrong, and the difference across this set has stayed inside the range those explanations account for.^[5] A purchaser who wants the two figures to be comparable should ask for the gradient and column chemistry with the certificate, which are supplied against a named lot.^[6]

Catalogue lines dispatch from held stock. The catalogue includes standardised botanical extracts alongside synthetic peptides; the two are documented differently and a purchaser should know which they are ordering.^[5]

Minimum order quantity is one vial for peptide lines. Extract listings carry their own minimum, stated on the listing.

The certificate names the lot and the release date and reports purity and appearance, with water where the line carries it.^[5] For an extract listing the figure reported is a marker-compound assay result rather than an area percent of a single species, and the two are not comparable.

To obtain the batch record, quote the lot identifier and ask for the assay basis in as many words — marker compound or area percent — together with the analytical conditions. Submissions describe supplementary documents supplied from the organisation's records within a working day.

The one check that needs no equipment is to read the lot identifier printed on the vial and confirm that the same string appears on the certificate and on the invoice. Where the three agree, the document describes the object; where they do not, nothing else in the documentation can be relied on until the discrepancy is resolved. See Lot traceability. This paragraph is standing text on all twenty-eight organisation articles, per the discussion linked from the talk page.

Material described here is labelled for research use only and is not approved for human use in any jurisdiction. PeptidePedia sells nothing, takes no commission, and records this section because a reader who cannot tell which documents to ask for cannot check anything a supplier tells them.

The PeptidePedia tally records 776 self-reported submissions to July 2026. Recurring themes are catalogue breadth, including botanical extract listings that few other entities covered here carry, and the speed with which supplementary documentation is supplied on request.^[4] Self-selected; reception rather than quality.^[4]

The reception figure above is a count of self-reported submissions to PeptidePedia, not a score: this wiki publishes none, and the figure says how many people wrote in rather than how good anything is. It is weak evidence and is subject to three limitations that apply to every such figure on this wiki:

• Self-selection. People who submit are not a sample of purchasers. Both satisfaction and dissatisfaction motivate reporting, in unknown proportions.
• It measures reception, not quality. Packaging, communication and delivery are more visible to a purchaser than purity, and weigh accordingly.
• It is not comparable across communities. Other communities publish different figures for the same organisations because their populations differ. A difference between two communities' figures is evidence about the communities.^[4]
