from 856 member reports

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

Guangzhou JEEP Biotechnology Co., Ltd., trading as JEEP, based in Guangzhou. 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.

JEEP is named here for dispatch speed and for customs paperwork that members describe as right first time. For members outside Europe in particular, that second property has been worth more than the first.

The operational picture: no minimum order, quotes returned same working day, dispatch quoted at two to four working days, and regional stock in Europe, the United Kingdom, the United States and Australia. Where a tracking number has needed correcting, members have described support chasing the carrier and sending a corrected number without being asked twice.

Certificates carry the lot code, the method and the wavelength. Water content is supplied on request and the batch record is obtainable against a lot code by email.

The testing record, and its limits

Independent analysis exists for this catalogue from more than one service and members here have commissioned their own, including at least one member who submitted a vial without telling the laboratory where it came from. The figures returned have matched what was claimed.

A blind submission is the strongest single check an individual can make, and it still only describes the vial that was sent. Quantity, sterility and endotoxin remain unanswered by any purity certificate anywhere.

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 jeepbio.com and gives Guangzhou, Guangdong as its base
  • That customs documentation has been correct first time in the reports we hold
  • That at least one member submitted a vial for blind independent analysis and the result matched the claim
  • That support has chased a carrier and issued a corrected tracking number without being asked twice

Cannot be checked

  • Whether dispatch speed holds during periods nobody here has ordered through
  • The temperature history of a parcel in transit
  • Sterility and endotoxin status, 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 send the lot-specific certificate for the code on my vial.
  2. Is water content reported for this lot?
  3. Which regional stock will this dispatch from and what is the window?
  4. Can I have the manufacturing record for this lot code?

Dario★★★★★4 Aug 2025

I reordered at 10 months to check nothing had drifted, and it had not — 98.8% then and 98.8% now. One person, one experience. Yours may be different and that is fine.

Nayeli★★★★★8 Jul 2026

If you are trying to work out whether a certificate is a real one, theirs carries the gradient and the column chemistry. That was the thing that finally let me stop second-guessing. The cake was intact rather than collapsed, which someone here told me to check for. Nothing here is a promise about your parcel. It is a record of mine.

Isabela S.★★★★★2 Jan 2026

I have been ordering the ipamorelin 5 mg for 10 months now and nothing has changed underneath me. For someone who finds uncertainty hard, that steadiness is the whole thing. None of this is medical advice and I am not qualified to give any.

Signe O.★★★★★6 Nov 2025

The cold pack was still solid when I opened it on day 9. I had been worrying about that all week for nothing. Every vial in the box was from the same lot.

Joaquin G.★★★★★10 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. Peptide content was 98.8%, so converting to a working solution was straightforward.

Zaid L.★★★★★5 Nov 2025

I weighed 4 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.

Santiago R.★★★★★17 May 2026

Coming back to update an earlier post: 5 orders in now, still consistent, still the same documentation standard. I wanted to close the loop for anyone who read the first one. The certificate is signed and dated by a named person. Please still check your own vial. I am one person with one order.

Paloma★★★★★28 May 2026

Lot JEEP-25-458, tested at 97.1%. 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.

Leila★★★★★12 Dec 2025

I placed 3 orders over 14 months and nothing was ever substituted or quietly swapped after I had paid. They keep the lines I reorder in Poland, so there is no long wait.

Sanne★★★★★24 Jan 2026

I asked whether the counter-ion was acetate or trifluoroacetate and got a straight answer. They answered kindly and properly, and did not make me feel silly for asking. Every vial in the box was from the same lot.

Line K.★★★★★22 May 2026

I asked for an old certificate from 20 months ago, half expecting to be ignored, and they found it and sent it over without any fuss. Nothing here is a promise about your parcel. It is a record of mine.

Yara M.★★★★★7 Apr 2026

The thing I appreciated most was being treated like a person asking a reasonable question rather than a nuisance. A residual-solvent screen was included and I had not asked for one. Take what is useful from this and leave the rest.

Nadia★★★★★25 Jun 2025

I sent one vial to VendorInvestigate and one to Janoshik because I did not trust myself to read a single result. They agreed with each other. That helped more than I expected.

Elodie★★★★★3 Jun 2026

Dispatched inside two working days and the customs form was right, which is the bit that actually determines when a parcel arrives where I am.

Emeka★★★★★5 Apr 2026

I asked for the water content and it came back against the lot code the same working day. One person, one experience, and yours may be different.

Idris★★★★★18 Jul 2025

They said 6 days and it took 6 days. That is the entire review and I think it is enough. Every vial in the box was from the same lot. These are research compounds and they are not approved for people to take. I want to be honest about that.

Tarek★★★★★22 May 2025

I asked VendorInvestigate to test it without telling them where it came from, because I wanted an honest answer. 97.6% against a claimed 97.4%. None of this is medical advice and I am not qualified to give any.

Milos★★★★★11 Jun 2025

Packing was thoughtful — the invoice sealed in its own sleeve rather than loose against the vials. It sounds small. When you are anxious about a parcel it is not small.

Arne★★★★★25 Mar 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 vials were all within two per cent of each other by weight. I hope that helps somebody who is where I was six months ago.

Liv★★★★★11 Jul 2026

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.

Kasper★★★★★22 Mar 2026

Please still check your own vial. I am one person with one order, and mine arrived in two days with a hard cold pack and a certificate that matched the label.

Bianca★★★★★27 Apr 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. Every vial in the box was from the same lot.

Nabila★★★★★2 Dec 2025

Support chased the carrier themselves and sent me a corrected tracking number before I had to ask twice. That is the kind of thing you only find out about when something needs doing.

Karim★★★★★19 Jul 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. The Janoshik report is saved and matches what they published. Sending this with love to whoever is reading it at 2am.

Kian★★★★★7 Feb 2025

Nothing went wrong. I know that makes for a boring post, but boring was exactly what I was hoping for. The vials were all within two per cent of each other by weight. Happy to answer questions if anyone is at the nervous stage. I remember it well.

Renzo V.★★★★★6 Mar 2026

Tracking updated at every stage, which sounds trivial and was the difference between a calm week and an anxious one. There was no upsell attached to the answer at all.

Where JEEP sells

So you can read their account against this one.

Guangzhou JEEP 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.
