Hana O.★★★★★
Reconstituted the thymosin alpha-1 5 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.

★★★★⯨A rating here summarises what members have said about ordering. It is not a safety rating and it cannot be one.
Zhuhai Kerui Biotechnology Co., Ltd., trading as KP, based in Zhuhai and giving 2016 as its founding year. 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
KP 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 keruipeptides.com and gives Zhuhai 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.
- Can you send the certificate for the lot number printed on my vial, not a representative one?
- Does the certificate include peptide content by weight as well as purity?
- How was this stored between manufacture and dispatch, and for how long?
Member reports
Published in full, including the unimpressed ones.
Laila T.★★★★★
Moved here after two bad lots elsewhere. 5 orders in and the VendorInvestigate numbers have been flat every single time.
Ferran V.★★★★★
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
Sofia Ma.★★★★★
PeptideMeter has now seen 7 of their lots through me. Not one has come back outside spec.
Diego B.★★★★★
One of the few places that will quote semax 10 mg at all, and the synthesis came back clean on an independent check.
Ruben B.★★★★★
Pleased to find they hold stock in the United Kingdom. Domestic dispatch, day 5, no customs step at all.
Bastian So.★★★★★
Weighed 8 vials from the semax 10 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
Diego A.★★★★★
First order, deliberately small, BPC-157 5 mg only. Documentation, transit and a Medutest result at 98.6% all checked out, so the next one will not be small.
Halima S.★★★★☆
Good communication throughout, accurate lead time, and the parcel arrived on day 5.
Enzo★★★★★
Cold pack was still hard on arrival in Austin on day 3. My logger never went above 6°C across the whole run.
Jarno F.★★★★★
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
Line C.★★★★★
Ordered on a Monday from their warehouse in the United Kingdom and it was here by day 2. That is the whole case for regional stock.
Gustav L.★★★★★
Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.
Marit N.★★★★★
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
Nayeli F.★★★★★
Every certificate I have from them is lot-specific. Not one batch-level document in 9 orders.
Sena E.★★★★★
No customs paperwork, no import wait — it came from their stock in the United States and arrived day 5.
Leila I.★★★★☆
Solid on the AOD-9604 5 mg. Purity where it should be, transit 2 days, paperwork in order.
Rina A.★★★★★
Dispatched from their warehouse in Germany rather than from the factory, so the tesamorelin 2 mg was with me on day 2.
Teodor T.★★★★★
Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.
Amira★★★★★
7 orders in eighteen months, no substitutions, no reformulations, everything in stock when the site said it was. Boring is the highest compliment I have.
Greta L.★★★★★
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
Noor P.★★★★☆
Everything about the order was routine in the best sense — quoted 3 days, arrived in 2.
Chiara G.★★★★★
Arrived on day 2 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.
Marisol O.★★★★★
Regional stock makes the difference — dispatched within the United States, day 4, cold pack still hard on arrival.
Priya A.★★★★★
Peptide content reported at 99.8% alongside the purity figure, so I could convert straight to a working mass.
Nabila B.★★★★★
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
