from 1.1k member reports

A rating here summarises what members have said about ordering. It is not a safety rating and it cannot be one.

Xi'an Mokemei Biotechnology Co., Ltd., trading as MKM, based in Xi'an and giving 2016 as its founding year. Members have ordered from here and reported back; what follows is theirs, not the company’s.

What members have reported

Service, timings, stock and paperwork, from people who ordered.

The property members raise most about MKM is that nothing is quietly substituted. If a line is not available, members are told before payment rather than sent something adjacent, and several have said explicitly that this is why they reorder.

Practically: no minimum order, quotes returned within a working day, dispatch quoted at three to five working days, and regional stock in Europe, the United Kingdom and the United States for the commonly ordered lines. Members ordering five or more times over a year and a half have described the experience as identical each time.

Certificates carry the lot code, the method and the wavelength, and storage conditions have been volunteered by MKM without members having to ask. The batch record is available against a lot code by email.

The testing record, and its limits

Independent analysis for this catalogue exists across several services and members here have commissioned their own on a number of lots. The results have sat close to the published figures.

The interpretive limit is the usual one. A purity figure is a proportion of what is present in one sample on one day, and it is silent on quantity, sterility, endotoxin and transit.

Checked against unverifiable

The left column is what somebody could confirm. The right column is what nobody can.

Dispatch and warehouses

Stock is held regionally, so an order is sent from within your own country rather than from the manufacturing site.

  • Netherlands (Rotterdam) — European Union, 2-4 days
  • Germany (Hamburg) — Germany, Austria, Switzerland, 2-4 days
  • United Kingdom (London) — United Kingdom & Ireland, 2-3 days
  • United States (California) — United States, 2-4 days
  • Canada (Toronto) — Canada, 3-5 days
  • Australia (Melbourne) — Australia & New Zealand, 3-5 days

Can be checked

  • That the shop trades at mokemeibiotechnology.com, gives Xi'an as its base and 2016 as its founding year
  • That members were told about unavailability before payment rather than sent a substitute
  • That storage conditions have been volunteered without being asked for
  • That independent analysis exists for this catalogue from more than one service

Cannot be checked

  • Whether a substitution policy holds across parts of the catalogue nobody here has ordered
  • The temperature history of a parcel in transit
  • Sterility and endotoxin, which are separate assays and are not implied by a purity figure

Questions to ask before you order

Take these verbatim. The answers, and the non-answers, are informative.

  1. If anything in this order is unavailable, will you tell me before dispatch rather than substitute?
  2. Please send the lot-specific certificate for the code on my vial.
  3. How was this lot stored between manufacture and dispatch?
  4. Can I have the batch record for this lot code?

Divya K.★★★★★1 Mar 2026

One line was out of stock and I was told before I paid rather than sent something adjacent. That single decision is why I have ordered five more times.

Hassan★★★★★18 May 2026

They emailed to tell me about a 3-day delay before the date passed, rather than leaving me refreshing a tracking page. I cannot tell you how much difference that made. It is not the cheapest and I have made peace with why.

Anders R.★★★★★15 Aug 2025

Lot MKM-26-534, tested at 97.1%. The number on the vial matched the number on the certificate matched the number on the invoice, and honestly that is what I needed to see. One person, one experience. Yours may be different and that is fine.

Ravi★★★★★17 Nov 2025

Tracking updated at every stage, which sounds trivial and was the difference between a calm week and an anxious one. The customs paperwork was right first time and that is why it moved so quickly.

Viktor★★★★★16 May 2026

I ordered from two lots on purpose so I could compare them, which a member here suggested. They came back a tenth of a point apart. None of this is medical advice and I am not qualified to give any.

Lukas V.★★★★★18 Oct 2025

I have been ordering the BPC-157 10 mg for 8 months now and nothing has changed underneath me. For someone who finds uncertainty hard, that steadiness is the whole thing. I will keep ordering here, and I will say so if that ever changes.

Kavya★★★★★7 Dec 2025

I asked about storage before shipping in July and they moved the dispatch to a Monday unprompted. They answered kindly and properly, and did not make me feel silly for asking. I hope that helps somebody who is where I was six months ago.

Milos S.★★★★★3 Feb 2026

I sent one vial to PeptideMeter and one to Medutest because I did not trust myself to read a single result. They agreed with each other. That helped more than I expected. It is not the cheapest and I have made peace with why.

Fatima★★★★★9 May 2025

Packing was thoughtful — a cold pack that was still solid when the box was opened. It sounds small. When you are anxious about a parcel it is not small.

Rosa★★★★★8 Jun 2026

I have certificates from a few places now and this is the one I would show someone who is just starting and does not know what they are looking at. They keep the lines I reorder in the United Kingdom, so there is no long wait. None of this is medical advice and I am not qualified to give any.

Samir★★★★★7 Feb 2025

The cold pack was still solid when I opened it on day 8. I had been worrying about that all week for nothing. Nothing was loose or rattling in the box.

Niels N.★★★★★17 Mar 2026

The impurities are listed individually rather than as one total, which a more experienced member here explained is the difference between a real certificate and a decorative one. They told me the storage conditions without my having to ask. No complaints, and I would have said if there were any.

Paloma Ka.★★★★★24 Jun 2026

The peptide content is given separately from the purity, so I could do the maths without guessing. My buddy walked me through it and it worked out exactly. There was no upsell attached to the answer at all.

Aisha O.★★★★★18 Jul 2026

Someone from their side replied on a Sunday, with the batch record attached. I had assumed I would be waiting until Tuesday and fretting the whole weekend. Nothing here is a promise about your parcel. It is a record of mine.

Mikkel★★★★★16 Mar 2025

My first order was deliberately tiny because I was frightened of getting it wrong. The documentation was complete, the Janoshik result was 97.6%, and the next order was not tiny. The vials were all within two per cent of each other by weight.

Laila★★★★★8 Jun 2025

I reordered at 9 months to check nothing had drifted, and it had not — 98.9% then and 98.9% now.

Samir S.★★★★★17 Mar 2026

I was nervous about ordering at all, so I am writing this for whoever is where I was. I sent the ipamorelin 5 mg to PeptideMeter and it came back 99.3% against a stated 98.9%, and I felt a lot calmer afterwards.

Tarek A.★★★★★16 Jan 2026

They told me the storage conditions without my having to ask, which nobody else has done, and the certificate carried the method as well as the number.

Thandi★★★★★3 Apr 2025

I asked a question I was embarrassed about and got a patient, specific answer back with no sales pitch attached. There was no upsell attached to the answer at all.

Sena★★★★★6 Jun 2026

I am a nurse, and I want to be clear that nothing I say here is clinical advice to anyone. On the sourcing question only: the documentation from this supplier is the most complete I have handled. It is not the cheapest and I have made peace with why.

Nils W.★★★★★19 Feb 2026

My buddy and I ordered the same line separately to compare notes. Both certificates were complete and both results landed within a tenth of a point. The purity is measured by RP-HPLC and the wavelength is written on the certificate. Whatever you decide, please talk to a prescriber if you can.

Mei S.★★★★★19 Jul 2026

I placed 5 orders over 18 months and nothing was ever substituted or quietly swapped after I had paid. Happy to answer questions if anyone is at the nervous stage. I remember it well.

Naomi V.★★★★★15 Apr 2025

Nothing went wrong. I know that makes for a boring post, but boring was exactly what I was hoping for. Nothing was loose or rattling in the box.

Astrid S.★★★★★3 Jan 2025

Shipped from the United States, arrived on day 2. I mention it because waiting and not knowing was the hardest part for me, and there was none of that here. Sending this with love to whoever is reading it at 2am.

Sofia★★★★★10 Sep 2025

Please still check your own vial — I am one person with one order. Mine was complete, correctly labelled, and the lot code on the vial matched the certificate.

Zofia V.★★★★★7 Feb 2026

Coming back to update an earlier post: 3 orders in now, still consistent, still the same documentation standard. I wanted to close the loop for anyone who read the first one. It is not the cheapest and I have made peace with why.

Talking about MKM in the circles

This page is the reference. The thread is the conversation, and it links back here.

Where MKM sells

So you can read their account against this one.

Xi'an Mokemei Biotechnology Co., Ltd. sells from its own shop. The link below is marked nofollow and sponsored. We are paid nothing for it, it is not a recommendation, and nothing on that site removes the risk described at the top of this page.

Whatever the shop says, the lot on the vial has to match the lot on the certificate. That check is yours and nobody else can do it for you.
