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. None of this is medical advice and I am not qualified to give any.

★★★★⯨A rating here summarises what members have said about ordering. It is not a safety rating and it cannot be one.
ChinaPeptides Co., Ltd. (QYAOBIO), trading as QYB, based in Shanghai and giving 2008 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.
QYB is named here for the depth of its catalogue and for labelling that members describe as consistently legible and correctly matched to the paperwork. That sounds like a low bar and members who order widely say plainly that it is not universally cleared.
The operational picture: no minimum order, quotes returned same or next working day, dispatch quoted at three to five working days, and regional stock in Europe, the United Kingdom and the United States. Members have described multi-item orders arriving as one consignment with a document per lot rather than a single summary sheet.
Certificates carry the lot code, the method and the detection wavelength. Members who wanted content by weight or the batch record have had both supplied against a lot code, usually within the working day.
The testing record, and its limits
The independent record for this catalogue runs across several years and more than one service, and members here have commissioned their own analysis on a number of lines. The comparisons that have been posted have sat close together.
Nothing in that record extends to the vial you are holding. A purity figure describes one sample; a lot may contain thousands of vials; and neither the figure nor the lot tells you anything about sterility or endotoxin.
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 qyaobiopeptides.com, gives Shanghai as its base and 2008 as its founding year
- That multi-item orders arrive with a document per lot, because members have posted the sets
- That independent analysis for this catalogue exists across more than one service and several years
- That labelling matches the paperwork in the reports we hold
Cannot be checked
- Which of a large catalogue's lines share a production run, which is not published by anybody here
- The transit conditions of your specific parcel
- Sterility, endotoxin and residual solvents, none of which a purity certificate reports
Questions to ask before you order
Take these verbatim. The answers, and the non-answers, are informative.
- Is there a separate certificate for each lot in this order?
- Can you report peptide content by weight as well as purity?
- Which stock is this dispatching from and what is the window?
- Can I have the manufacturing record for this lot code?

Sofia A.★★★★★
Tracking updated at every stage, which sounds trivial and was the difference between a calm week and an anxious one. I will keep ordering here, and I will say so if that ever changes.
Arne E.★★★★★
Shipped from Ireland, arrived on day 8. I mention it because waiting and not knowing was the hardest part for me, and there was none of that here. Happy to answer questions if anyone is at the nervous stage. I remember it well.
Aurel E.★★★★★
The cold pack was still solid when I opened it on day 7. I had been worrying about that all week for nothing.
Mateusz S.★★★★★
I reordered at 24 months to check nothing had drifted, and it had not — 97.0% then and 97.0% now. The vials were all within two per cent of each other by weight.
Elin O.★★★★★
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. Take what is useful from this and leave the rest.
Bilal A.★★★★★
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. They told me the storage conditions without my having to ask.
Omar★★★★★
Coming back to update an earlier post: 10 orders in now, still consistent, still the same documentation standard. I wanted to close the loop for anyone who read the first one. The purity is measured by RP-HPLC and the wavelength is written on the certificate.
Sten★★★★★
I want to say clearly that I am not medically trained and this is not advice. What I can say is that the sourcing side of this went smoothly and the paperwork held up. The reply came back the same day and it actually answered what I asked. I hope that helps somebody who is where I was six months ago.
Freya I.★★★★★
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. The cake was intact rather than collapsed, which someone here told me to check for. No complaints, and I would have said if there were any.
Bilal P.★★★★★
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. There was no upsell attached to the answer at all. Take what is useful from this and leave the rest.
Petra R.★★★★★
I have been ordering the tesamorelin 2 mg for 24 months now and nothing has changed underneath me. For someone who finds uncertainty hard, that steadiness is the whole thing. The paperwork is genuinely half of what you are paying for.
Chiara I.★★★★★
I asked for the release date on the lot and had it the same day. They answered kindly and properly, and did not make me feel silly for asking. They told me the storage conditions without my having to ask.
Adnan B.★★★★★
Every vial legible, every code matching the document, on a nine-item order. I had budgeted an afternoon for checking it and it took eleven minutes.
Sten Z.★★★★★
If you are trying to work out whether a certificate is a real one, theirs carries peptide content stated separately from purity. That was the thing that finally let me stop second-guessing. Nothing was loose or rattling in the box.
Tobias D.★★★★★
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. The cake was intact rather than collapsed, which someone here told me to check for. These are research compounds and they are not approved for people to take. I want to be honest about that.
Tarek C.★★★★★
They were willing to quote something that other places would not even reply to me about, and it came back clean when I had it checked. Happy to answer questions if anyone is at the nervous stage. I remember it well.
Hedda O.★★★★★
I placed 9 orders over 24 months and nothing was ever substituted or quietly swapped after I had paid.
Karim B.★★★★★
I asked for content by weight as well as purity and it came back the same working day against the lot code. No fuss and no explanation required.
Milan B.★★★★★
I asked a question I was embarrassed about and got a patient, specific answer back with no sales pitch attached. Every vial in the box was from the same lot. None of this is medical advice and I am not qualified to give any.
Mariam★★★★★
I weighed 9 of the vials against the label, which I know is a slightly odd thing to do, and they were all within two per cent. It made me feel better about the whole batch. Nothing was loose or rattling in the box.
Farid L.★★★★★
The site said it was in stock and it genuinely was, and it went out the same day. After being let down elsewhere that mattered a lot. Their figure and the lab figure were a tenth of a point apart. One person, one experience. Yours may be different and that is fine.
Cato A.★★★★★
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. The vials were all within two per cent of each other by weight. I am glad I asked before I ordered, and I would say ask.
Ignacio A.★★★★★
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. Peptide content was 98.6%, so converting to a working solution was straightforward. No complaints, and I would have said if there were any.
Teodor H.★★★★★
My first order was deliberately tiny because I was frightened of getting it wrong. The documentation was complete, the Janoshik result was 96.8%, and the next order was not tiny. They told me the storage conditions without my having to ask.
Sanne I.★★★★★
The purity is measured by RP-HPLC and the wavelength is written on the certificate, which is the detail I now look for first anywhere I order.
Talking about QYB in the circles
This page is the reference. The thread is the conversation, and it links back here.
QYB, big orders and whether the labelling holds up
Nine items in one QYB order and I checked every label against every document, because I am the sort of person who does that. All nine legible, all nine codes matching, one certificate per lot rather…
Where QYB sells
So you can read their account against this one.
ChinaPeptides Co., Ltd. (QYAOBIO) 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.
