from 586 member reports

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

Qingdao Saber Technology Pharmaceutical, trading as QST, based in Qingdao and giving 2017 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.

QST is described in reports here as easy to deal with. Ordering is simple, the confirmations are prompt, and members have not had to chase anything twice.

The operational picture: no minimum order, quotes returned same or next working day, dispatch quoted at two to four working days, and regional stock in Europe, the United Kingdom and the United States for the lines this community reorders. Members have described cold packs arriving hard on day three and four.

The certificate carries the lot code, the method and the wavelength. Water content is supplied on request and the batch record is obtainable against a lot code, in both cases usually inside the working day.

The testing record, and its limits

Independent analysis exists for this catalogue across more than one service, and members here have commissioned their own on several lines. Where the two have been compared, they have agreed.

What that comparison establishes is narrow. It says the sample that was tested was what it was said to be. It does not speak to fill quantity, to sterility, or to anything that happened to the vial after the sample was drawn.

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 qingdaosabertechnology.com, gives Qingdao as its base and 2017 as its founding year
  • That independent analysis exists for this catalogue from more than one service
  • That water content and the batch record are supplied on request against a lot code
  • That members here have reordered and described the process as unchanged

Cannot be checked

  • Whether the trading name here relates to any similarly named business elsewhere
  • What conditions your parcel travelled under after dispatch
  • Sterility and endotoxin status, which are separate assays nobody here has commissioned

Questions to ask before you order

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

  1. Please send the certificate specific to my lot code.
  2. Can you add water content to the certificate for this lot?
  3. Which regional stock is this shipping from?
  4. Can you send the manufacturing record for this lot?

Member reports

Dagny E.★★★★★13 Nov 2025

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 customs paperwork was right first time and that is why it moved so quickly.

Erez R.★★★★★16 Jan 2025

The lot code on the vial matched the paperwork. A member here told me that is the first thing to check, and they were right that it tells you a lot. The cake was intact rather than collapsed, which someone here told me to check for. None of this is medical advice and I am not qualified to give any.

Valeria S.★★★★★19 Feb 2025

Ordered on the Monday, dispatched on the Wednesday, in my hands on the Friday, cold pack hard. There is nothing else to say about it and that is the point.

Elin Y.★★★★★27 Jun 2025

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. Take what is useful from this and leave the rest.

Anjali★★★★★23 Dec 2025

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.

Farid B.★★★★★5 Jul 2026

Tracking updated at every stage, which sounds trivial and was the difference between a calm week and an anxious one. The catalogue really does have what it says it has.

Noor K.★★★★★18 Jan 2026

Shipped from Poland, 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. The customs paperwork was right first time and that is why it moved so quickly.

Bilal K.★★★★★8 Jan 2025

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. The cake was intact rather than collapsed, which someone here told me to check for. I will keep ordering here, and I will say so if that ever changes.

Rosa B.★★★★★7 Jul 2026

Nothing went wrong. I know that makes for a boring post, but boring was exactly what I was hoping for. They told me the storage conditions without my having to ask.

Rohan M.★★★★★27 Sep 2025

I asked for the lot-specific document and it came back within the hour. Whatever their process is for that, it is a good one.

Mei A.★★★★★16 Feb 2026

I have been ordering the retatrutide 10 mg for 9 months now and nothing has changed underneath me. For someone who finds uncertainty hard, that steadiness is the whole thing. They keep the lines I reorder in the United Kingdom, so there is no long wait.

Kasper H.★★★★★8 Aug 2025

My first order was deliberately tiny because I was frightened of getting it wrong. The documentation was complete, the PeptideMeter result was 98.6%, and the next order was not tiny. Happy to answer questions if anyone is at the nervous stage. I remember it well.

Rania L.★★★★★11 Apr 2025

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. Their figure and the lab figure were a tenth of a point apart. The paperwork is genuinely half of what you are paying for.

Thandi A.★★★★★25 Dec 2025

The cold pack was still solid when I opened it on day 4. I had been worrying about that all week for nothing. I am glad I asked before I ordered, and I would say ask.

Chidi★★★★★18 Mar 2026

I asked Medutest to test it without telling them where it came from, because I wanted an honest answer. 98.7% against a claimed 98.3%. They told me the storage conditions without my having to ask.

Joaquin S.★★★★★26 Jun 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 was loose or rattling in the box. None of this is medical advice and I am not qualified to give any.

Kavya K.★★★★★9 May 2026

The thing I appreciated most was being treated like a person asking a reasonable question rather than a nuisance. The desiccant was inside the sealed container where it should be. Happy to answer questions if anyone is at the nervous stage. I remember it well.

Lucia L.★★★★★25 May 2025

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. Take what is useful from this and leave the rest.

Milan★★★★★23 Nov 2025

These are research compounds and they are not approved for people to take, and I want to be honest about that. On the narrow question of the supplier: the paperwork was complete and the codes matched.

Santiago E.★★★★★5 Jan 2026

They said 6 days and it took 6 days. That is the entire review and I think it is enough. The certificate is signed and dated by a named person. One person, one experience. Yours may be different and that is fine.

Dario N.★★★★★19 Jan 2025

I placed 5 orders over 10 months and nothing was ever substituted or quietly swapped after I had paid. Please still check your own vial. I am one person with one order.

Amara R.★★★★★7 Jul 2026

Lot QST-25-710, tested at 99.5%. 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. Every vial in the box was from the same lot.

Jarno★★★★★19 Jan 2026

The kisspeptin-10 5 mg went completely clear when I reconstituted it — no cloudiness, nothing floating. Somebody on here told me that is what to look for, and now I am passing it on. They keep the lines I reorder in Germany, so there is no long wait.

Yusuf★★★★★12 May 2026

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. It is not the cheapest and I have made peace with why. These are research compounds and they are not approved for people to take. I want to be honest about that.

Solene★★★★★28 Jul 2025

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. 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.

Ines L.★★★★★7 Jun 2026

I weighed 8 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. The certificate is signed and dated by a named person.

Where QST sells

So you can read their account against this one.

Qingdao Saber Technology Pharmaceutical 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.
