from 535 member reports

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

Sangon Biotech (Shanghai) Co., Ltd., trading as SGN, based in Shanghai and giving 2004 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.

SGN has been supplying life-science laboratories since 2004 and reads that way in members' accounts: a broad catalogue, an ordering process built for institutional buyers, and correspondence that is businesslike rather than warm.

Practically: no minimum order for catalogue items, quotes returned within a working day, dispatch quoted at three to five working days, and regional stock in Europe and the United Kingdom for the lines this community reorders. Members have described cold packs still solid on day three.

The certificate carries the lot code, the assay method and the detection wavelength, and members who asked have had the water content and the batch record supplied against a lot code. Where a quote needed correcting, members describe it being corrected inside a single reply with the price held.

The testing record, and its limits

Independent analysis exists for this catalogue from more than one service and members here have commissioned their own on several lines. The figures have been consistent with the published ones.

The general caveat holds here as everywhere. A certificate describes a sample, a sample stands for a lot, and a lot is not the vial in your fridge until somebody tests that vial. Sterility and endotoxin are not addressed at all.

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 sangonbio.com, gives Shanghai as its base and 2004 as its founding year
  • That water content and the batch record are supplied on request against a lot code
  • That independent analysis exists for this catalogue from more than one service
  • That a corrected quote has held its price inside a single reply in the reports we hold

Cannot be checked

  • Which parts of a broad life-science catalogue are manufactured and which are distributed
  • The conditions your parcel travelled under after dispatch
  • 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.

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

Rina★★★★★8 Jun 2026

The cold pack was hard on day three and the ordering process felt like buying from a laboratory supplier, which is what they are. None of this is medical advice and I am not qualified to give any.

Salma★★★★★7 Feb 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. Their figure and the lab figure were a tenth of a point apart.

Lina★★★★★8 Jul 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. The vials were all within two per cent of each other by weight.

Helga★★★★★17 Sep 2025

I asked for the lot-specific document and it came back within the hour. That has now happened twice and I have stopped expecting to have to chase it.

Kaia★★★★★2 Jun 2026

A quote needed correcting and it was corrected inside a single reply with the price held. I am still ordering from them, which probably says it.

Kaia P.★★★★★18 Oct 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. Nothing was loose or rattling in the box.

Oskar★★★★★4 Apr 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. There was no upsell attached to the answer at all.

Hedda★★★★★22 Apr 2025

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.

Adaeze★★★★★23 Aug 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. Nothing here is a promise about your parcel. It is a record of mine.

Petra★★★★★22 Nov 2025

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. The purity is measured by RP-HPLC and the wavelength is written on the certificate.

Tobias★★★★★9 Aug 2025

Nothing went wrong. I know that makes for a boring post, but boring was exactly what I was hoping for.

Divya★★★★★25 Jul 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 paperwork is genuinely half of what you are paying for.

Katrin★★★★★23 Feb 2025

They said 5 days and it took 5 days. That is the entire review and I think it is enough. There was no upsell attached to the answer at all.

Yara★★★★★22 Jan 2025

I have been ordering the NAD+ 500 mg for 8 months now and nothing has changed underneath me. For someone who finds uncertainty hard, that steadiness is the whole thing.

Vikram★★★★★25 Jan 2025

None of this is medical advice and I am not qualified to give any. On the narrow question: the label was legible, the lot code matched the paperwork, and the independent figure matched the published one.

Hana★★★★★9 Jul 2026

The purity is measured by RP-HPLC and the wavelength is written on the certificate. I have started refusing to order anywhere that will not tell me that much.

Teodor★★★★★14 Jun 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.

Oskar S.★★★★★5 Apr 2026

I was nervous about ordering at all, so I am writing this for whoever is where I was. I sent the NAD+ 500 mg to PeptideMeter and it came back 97.0% against a stated 97.2%, and I felt a lot calmer afterwards.

Cormac★★★★★24 Sep 2025

The cold pack was still solid when I opened it on day 3. I had been worrying about that all week for nothing. There was no upsell attached to the answer at all.

Bence★★★★★2 Jan 2026

I asked for an old certificate from 8 months ago, half expecting to be ignored, and they found it and sent it over without any fuss. Their figure and the lab figure were a tenth of a point apart.

Ingrid★★★★★12 Mar 2026

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

Zaid★★★★★17 Jun 2026

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 purity is measured by RP-HPLC and the wavelength is written on the certificate. I will keep ordering here, and I will say so if that ever changes.

Zaid R.★★★★★6 Aug 2025

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. Nothing here is a promise about your parcel. It is a record of mine.

Naomi★★★★★28 May 2026

I asked Medutest to test it without telling them where it came from, because I wanted an honest answer. 97.4% against a claimed 97.6%. These are research compounds and they are not approved for people to take. I want to be honest about that.

Kenji★★★★★22 Apr 2026

I reordered at 14 months to check nothing had drifted, and it had not — 98.8% then and 98.8% now. There was no upsell attached to the answer at all.

Ewan★★★★★3 Mar 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. Their figure and the lab figure were a tenth of a point apart.

Where SGN sells

So you can read their account against this one.

Sangon Biotech (Shanghai) 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.
