(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.{{r|registry,selfpub}} The organisation is one of twenty covered on PeptidePedia under [[Project:Vendor notability]]. Like the others, it distributes material labelled [[Research use only|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.{{r|ruo}} 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]].{{r|tally}} == Corporate identity and history == 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.{{r|registry}} 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.{{r|selfpub}} The documentary base is the registry record and the organisation's own material, plus purchaser reports. No independent coverage has been identified. == Distribution and dispatch == 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. == Operations and documentation practice == Purchaser reports describe conventional vialled lyophilised material with a batch certificate.{{r|reports}} Reported certificate content has been variable within this set — some reporting purity and water, others purity alone — and two submissions noted a certificate whose lot identifier did not correspond to the vial label, which is a [[Lot traceability|traceability]] failure rather than a quality finding but is recorded here because it is the kind of discrepancy this wiki exists to document.{{r|reports}} That observation rests on two reports and is not generalisable. It is stated because omitting it would be a selection decision, not because two reports establish a pattern. == Product range == | Class | Representative listings | Documentation reported | |---|---|---| | Incretin analogues | Semaglutide, tirzepatide | Certificate, variable content | | Research peptides | Repair and secretagogue peptides | Certificate, variable content | | Extract-derived materials | Botanical extracts, standardised | Certificate, assay basis unclear | | SARMs and raw materials | Bulk | Certificate, purity only | 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 purity|area percent]] of a single species, and a purity figure on such a material means something different.{{r|selfpub}} == Independent testing record == Submitted reports on MKM material to July 2026 cover the incretin range and a small number of repair peptides. Reported [[Area percent purity|area percent]] figures have been high in most cases, with two reports in the set falling below the accompanying certificate by more than a percentage point.{{r|reports}} A discrepancy of that size between an independent report and a certificate has several innocent explanations — different columns, different integration parameters, different [[Reference standard|reference standards]], sample handling between purchase and testing — and does not establish that either figure was wrong. It is recorded because [[Purity claim inflation|inflated purity claims]] are a documented failure mode in this sector and a discrepancy is the only observable that would indicate one.{{r|reports}} == Reception == The PeptidePedia tally records 776 self-reported submissions to July 2026 — below the median for the supplier articles. Recurring complaints concern certificate consistency and the lot-matching discrepancies noted above; recurring positive themes are price and catalogue breadth.{{r|tally}} Self-selected; reception rather than quality.{{r|tally}} === How this tally should be read === The reception figure above is a mean of self-reported submissions to PeptidePedia. 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.{{r|tally}} PeptidePedia does not rank suppliers and does not maintain a league table. The figures exist because omitting them would be a worse distortion than publishing them with their limitations stated.{{r|tally}} == Regulatory position and legal status == The organisation is a commercial entity registered in the People's Republic of China. Nothing in the available record indicates a manufacturing authorisation, marketing authorisation or pharmacopoeial registration in any jurisdiction, and none should be inferred from a registered business scope, which is a licensing fact and not a quality assurance.{{r|registry}} Material labelled [[Research use only|for research use only]] is outside the regulatory framework that governs medicines. Its identity, purity, sterility and [[Bacterial endotoxin test|endotoxin]] content are not assured by any regulator, and a [[Certificate of analysis|certificate of analysis]] issued by a supplier is a claim by that supplier rather than an independent finding.{{r|ruo,usp1503}} Import of such material for personal use is unlawful or restricted in many jurisdictions, and [[Customs seizure|seizure]] is a documented outcome. PeptidePedia describes the legal position and does not advise on it.{{r|ruo}} == Notability and coverage == This article exists because the organisation satisfies at least three of the five criteria at [[Project:Vendor notability]]. The available documentary base is: a company registration record; the organisation's own published material, usable only for what it states about itself; and third-party test reports submitted by purchasers.{{r|registry,selfpub,reports}} What is '''not''' available is independent coverage in a source unconnected with the organisation or its customers. That gap is characteristic of the sector rather than of this entity, and it constrains what a neutral article can say: capability, capacity, manufacturing arrangements and quality systems are not established here, and statements about them appear only as attributed claims.{{r|selfpub}} Two frameworks are named in this article only to say what has ''not'' been established against them: a quality-system claim is not a fact until assessed against the applicable good-manufacturing-practice framework,{{r|gmp}} and a testing laboratory's competence is a matter of accreditation to a recognised standard rather than of self-description.{{r|iso17025}} Neither assessment is available here for this organisation or for any other covered on this wiki. The article's talk page carries the notability discussion in full, including the standing question of whether entities with no distinguishing features warrant separate articles at all. == External links == * [https://mokemeibiotechnology.com/ Visit MKM] == References == {{reflist}} <ref name="registry">National Enterprise Credit Information Publicity System (国家企业信用信息公示系统), company registration record, retrieved 2026.
