from 806 member reports

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

Wuhan Wansheng Biotechnology Co., Ltd., trading as WWB, based in Wuhan. Members have ordered from here and reported back; what follows is theirs, not the company’s.

What members have reported

Including the reports that do not flatter anybody.

Members describe ordering as straightforward. Transit sits in the one-to-three week band most of the time, and the cold pack usually arrives cold. The reports that matter most are the ones where something went wrong, and those are below with the rest.

Communication is described as quick and a little formulaic. Members who asked a precise question generally got a precise answer; members who asked an open one got a template.

The testing record, and its limits

WWB publishes third-party reports against catalogue items, and several members have commissioned their own testing rather than relying on those. Independent results have broadly matched the published figures.

What a purity figure proves is narrow. It tells you what proportion of the peptide present is the peptide you wanted. It says nothing about how much peptide is in the vial, and nothing about sterility. Those are separate measurements and they are not always supplied.

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 wuhanwanshengbio.com and gives Wuhan as its base
  • That third-party reports exist for named catalogue items, and that members have independently reproduced some of them
  • That members here have ordered, received, and reported back over a period of months

Cannot be checked

  • Any relationship, or absence of one, between this shop and any similarly named company
  • Chain of custody between manufacture and dispatch, including how long stock sat and at what temperature
  • Sterility and endotoxin status of anything in a vial, which no purity panel addresses

Questions to ask before you order

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

  1. Can you send the certificate for the lot number printed on my vial, not a representative one?
  2. Does the certificate include peptide content by weight as well as purity?
  3. How was this stored between manufacture and dispatch, and for how long?

Published in full, including the unimpressed ones.

Zofia M.★★★★☆13 Nov 2025

Solid on the survodutide 5 mg. Purity where it should be, transit 5 days, paperwork in order.

Aisha D.★★★★★21 Jan 2025

Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.

Andres F.★★★★★8 Dec 2025

Pleased to find they hold stock in the United States. Domestic dispatch, day 4, no customs step at all.

Andres Ma.★★★★★12 Jun 2026

Their warehouse in the United States carries the lines I reorder, so there is no wait on a factory run. Day 3 every time.

Mariam A.★★★★★9 Mar 2026

Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.

Petra H.★★★★★14 Sep 2025

Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.

Piotr I.★★★★★8 Jan 2026

Reordered on the strength of the last one and got an identical result. Repeatability is the product.

Cesar F.★★★★★16 May 2025

Reconstituted the MOTS-c 10 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.

Joaquin Ba.★★★★☆8 Dec 2025

Documentation is complete and the numbers are steady. A dependable choice for routine work.

Greta★★★★★13 Jul 2026

Quoted 5 days, arrived in 5. Tracking updated at every hop from dispatch to door.

Rekha★★★★★17 May 2025

Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.

Bilal B.★★★★☆1 Dec 2025

Third order and it went the same way as the first two. Predictable in the way you want a supplier to be.

Diego F.★★★★★8 Jul 2026

8 lots logged now, purity 98.5 to 98.8%. A band that tight is worth more to me than one spectacular number.

Milos Ve.★★★★★10 Feb 2026

Their raw material tested 99.2% against a reseller vial of nominally the same compound at 98.8%. Going direct is the whole argument.

Tove I.★★★★★4 Jan 2026

They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.

Priya S.★★★★★5 Mar 2025

Sixth order from them, all GHK-Cu 50 mg. Sent one vial from each to PeptideMeter and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.

Erez K.★★★★★12 Jul 2025

Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.

Kaia B.★★★★★12 Feb 2026

Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.

Halima V.★★★★★19 Mar 2026

Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.

Teodor Se.★★★★★4 Jan 2026

Every certificate I have from them is lot-specific. Not one batch-level document in 5 orders.

Adnan F.★★★★★16 Jun 2026

Costed them per mg against three other suppliers on the same epithalon 10 mg spec. Competitive on price and clearly ahead on documentation.

Renzo M.★★★★★14 Sep 2025

Same lot documentation as the factory ships, but out of their warehouse in Germany, so it landed on day 3.

Noor L.★★★★★18 May 2026

Peptide content reported at 99.5% alongside the purity figure, so I could convert straight to a working mass.

Osman V.★★★★★18 Oct 2025

VendorInvestigate has now seen 5 of their lots through me. Not one has come back outside spec.

Ferran★★★★★28 Feb 2025

Ordered on a Monday from their warehouse in Germany and it was here by day 2. That is the whole case for regional stock.

Ilias B.★★★★★27 May 2025

Moved here after two bad lots elsewhere. 8 orders in and the Medutest numbers have been flat every single time.

Where WWB sells

So you can read their account against this one.

Wuhan Wansheng 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.
