from 803 member reports

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

Shanghai Wibson Biotechnology Co., Ltd., trading as SWB, based in Shanghai and giving 2019 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.

SWB is described in reports here as tidy. Packing is the detail members raise first: each lot separately documented, the codes legible, and the paperwork set matching the contents of the box without anybody having to reconcile it.

Ordering is unremarkable in the way members want it to be. Quotes returned within a working day, dispatch quoted at three to five working days, no minimum order, and regional stock in Europe, the United Kingdom and the United States for the lines this community reorders most.

The certificate carries the lot code, the assay method, the wavelength and the water content. Members who have wanted the manufacturing record behind a lot have had it sent after a single request quoting the code.

The testing record, and its limits

Independent analysis for this catalogue exists across several lots and members here have added their own commissioned results. Read as a series, the record is consistent, which is a stronger claim than any single figure in it.

The limits are the ordinary ones and they are worth stating rather than assuming. A purity percentage is a proportion of what was in the injected sample. It is silent on quantity, on sterility, and on everything that happened 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 shanghaiwibsonbiotechnology.net, gives Shanghai as its base and 2019 as its founding year
  • That each lot in a multi-lot order arrives separately documented — members have photographed the paperwork set
  • That independent analysis exists for this catalogue from more than one testing service
  • That members here have reordered and described the documentation as unchanged between orders

Cannot be checked

  • Whether a catalogue line is manufactured in-house or bought in, which no supplier in this market discloses
  • The conditions your parcel travelled under between dispatch and delivery
  • Sterility and endotoxin, which are separate assays with separate costs

Questions to ask before you order

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

  1. Please confirm each lot in this order has its own certificate.
  2. Is the water content on the certificate, and what method was used?
  3. Which regional stock is this shipping from?
  4. Can you send the batch record for this lot code?

Katrin L.★★★★★20 Sep 2025

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. Nothing was loose or rattling in the box. Nothing here is a promise about your parcel. It is a record of mine.

Teodor R.★★★★★14 Feb 2025

I asked Medutest to test it without telling them where it came from, because I wanted an honest answer. 99.3% against a claimed 99.3%. The catalogue really does have what it says it has.

Rafael★★★★★21 Oct 2025

I placed 3 orders over 14 months and nothing was ever substituted or quietly swapped after I had paid. No complaints, and I would have said if there were any.

Tuva S.★★★★★27 Sep 2025

I asked for an old certificate from 6 months ago, half expecting to be ignored, and they found it and sent it over without any fuss. They told me the storage conditions without my having to ask.

Tove C.★★★★★4 Dec 2025

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 customs paperwork was right first time and that is why it moved so quickly. I hope that helps somebody who is where I was six months ago.

Hamza★★★★★21 Apr 2025

If you are trying to work out whether a certificate is a real one, theirs carries water content by Karl Fischer. That was the thing that finally let me stop second-guessing. None of this is medical advice and I am not qualified to give any.

Vikram V.★★★★★5 Aug 2025

The GHK-Cu 50 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. Take what is useful from this and leave the rest.

Liv P.★★★★★14 Jun 2026

They said 3 days and it took 3 days. That is the entire review and I think it is enough. The catalogue really does have what it says it has. These are research compounds and they are not approved for people to take. I want to be honest about that.

Liv Z.★★★★★18 Feb 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. Peptide content was 97.5%, so converting to a working solution was straightforward. Sending this with love to whoever is reading it at 2am.

Sanne Z.★★★★★16 Jan 2026

Four lots in one box and four separate certificates, each matching its own vials. I did not have to reconcile anything, which after my last supplier was a small joy.

Andres★★★★★26 Jul 2025

My first order was deliberately tiny because I was frightened of getting it wrong. The documentation was complete, the VendorInvestigate result was 96.9%, and the next order was not tiny. It is not the cheapest and I have made peace with why. I will keep ordering here, and I will say so if that ever changes.

Andres S.★★★★★11 Feb 2025

Shipped from France, 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. The Janoshik report is saved and matches what they published.

Runa A.★★★★★23 Apr 2026

I weighed 10 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. Please still check your own vial. I am one person with one order.

Laila V.★★★★★2 Apr 2025

I was nervous about ordering at all, so I am writing this for whoever is where I was. I sent the tesamorelin 2 mg to PeptideMeter and it came back 98.8% against a stated 98.7%, and I felt a lot calmer afterwards. The catalogue really does have what it says it has. I hope that helps somebody who is where I was six months ago.

Milos K.★★★★★19 Jul 2026

Lot SWB-24-736, tested at 98.5%. 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. There was no upsell attached to the answer at all. Nothing here is a promise about your parcel. It is a record of mine.

Bianca P.★★★★★5 Dec 2025

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. I am glad I asked before I ordered, and I would say ask.

Tobias A.★★★★★27 Jun 2025

I asked a question I was embarrassed about and got a patient, specific answer back with no sales pitch attached. No complaints, and I would have said if there were any.

Vikram S.★★★★★15 Mar 2026

I reordered at 10 months to check nothing had drifted, and it had not — 98.2% then and 98.2% now. The PeptideMeter report is saved and matches what they published.

Sanne C.★★★★★12 Mar 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. The desiccant was inside the sealed container where it should be. I hope that helps somebody who is where I was six months ago.

Renzo K.★★★★★3 Mar 2026

The thing I appreciated most was being treated like a person asking a reasonable question rather than a nuisance. The purity is measured by RP-HPLC and the wavelength is written on the certificate. Nothing here is a promise about your parcel. It is a record of mine.

Arto★★★★★24 Apr 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. There was no upsell attached to the answer at all.

Yannick★★★★★20 Mar 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. They told me the storage conditions without my having to ask. These are research compounds and they are not approved for people to take. I want to be honest about that.

Georgi P.★★★★★5 Sep 2025

Second order, identical paperwork to the first, down to the layout. Consistency between orders is the thing I have learned to look for and it is rarer than it should be.

Noor M.★★★★★14 Feb 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. Whatever you decide, please talk to a prescriber if you can.

Aleksi V.★★★★★13 Aug 2025

The cold pack was still solid when I opened it on day 4. I had been worrying about that all week for nothing.

Milos L.★★★★★19 Jul 2026

Nothing went wrong. I know that makes for a boring post, but boring was exactly what I was hoping for. The purity is measured by RP-HPLC and the wavelength is written on the certificate. Take what is useful from this and leave the rest.

Where SWB sells

So you can read their account against this one.

Shanghai Wibson 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.
