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. A residual-solvent screen was included and I had not asked for one.
Halima A.★★★★★16 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. They told me the storage conditions without my having to ask.
Chidi M.★★★★★24 Sep 2025
I placed 10 orders over 9 months and nothing was ever substituted or quietly swapped after I had paid.
Mateusz Z.★★★★★3 Jun 2025
I asked Janoshik to test it without telling them where it came from, because I wanted an honest answer. 98.5% against a claimed 98.5%. Whatever you decide, please talk to a prescriber if you can.
Sigrid P.★★★★★26 Dec 2025
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 PeptideMeter report is saved and matches what they published. Take what is useful from this and leave the rest.
Piotr F.★★★★★4 Aug 2025
I weighed 5 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.
Nabila N.★★★★★2 Feb 2026
I asked a question I was embarrassed about and got a patient, specific answer back with no sales pitch attached. The customs paperwork was right first time and that is why it moved so quickly. Happy to answer questions if anyone is at the nervous stage. I remember it well.
Hugo M.★★★★★17 Jan 2025
The kisspeptin-10 5 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. I am glad I asked before I ordered, and I would say ask.
Anders Ro.★★★★★2 May 2026
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. Every vial in the box was from the same lot.
Emil K.★★★★★7 Aug 2025
They emailed to tell me about a 2-day delay before the date passed, rather than leaving me refreshing a tracking page. I cannot tell you how much difference that made. 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.
Marit O.★★★★★16 Nov 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. The Medutest report is saved and matches what they published. No complaints, and I would have said if there were any.
Chiara S.★★★★★19 Jul 2026
The peak table on the certificate is what sold me. I had spent a year looking at single percentages and not understanding what they were made of, and one properly laid out document taught me more than any guide.
Amara A.★★★★★10 Mar 2026
Lot BCH-26-381, tested at 97.2%. 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. Sending this with love to whoever is reading it at 2am.
Zeynep★★★★★27 Jul 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. They told me the storage conditions without my having to ask. Take what is useful from this and leave the rest.
Sofia N.★★★★★7 Aug 2025
Nothing went wrong. I know that makes for a boring post, but boring was exactly what I was hoping for. 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.
Niels I.★★★★★4 May 2025
I have been ordering the thymosin alpha-1 5 mg for 15 months now and nothing has changed underneath me. For someone who finds uncertainty hard, that steadiness is the whole thing.
Kavya O.★★★★★28 Sep 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 VendorInvestigate report is saved and matches what they published. I hope that helps somebody who is where I was six months ago.
Rania La.★★★★★19 Jul 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. They keep the lines I reorder in France, so there is no long wait. Sending this with love to whoever is reading it at 2am.
Anya V.★★★★★6 Jun 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. I will keep ordering here, and I will say so if that ever changes.
Zaid F.★★★★★18 Jul 2026
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. They told me the storage conditions without my having to ask.
Mikkel K.★★★★★17 Jan 2026
I asked about storage before shipping in July and they moved the dispatch to a Monday unprompted. They answered kindly and properly, and did not make me feel silly for asking. Please still check your own vial. I am one person with one order.
Dario O.★★★★★2 Apr 2026
Packing was thoughtful — each vial wrapped separately with foam cut to fit. It sounds small. When you are anxious about a parcel it is not small.
Ewan M.★★★★★16 Jan 2025
I was nervous about ordering at all, so I am writing this for whoever is where I was. I sent the TB-500 5 mg to VendorInvestigate and it came back 99.0% against a stated 98.9%, and I felt a lot calmer afterwards. The certificate is signed and dated by a named person. One person, one experience. Yours may be different and that is fine.
Omar A.★★★★★9 Apr 2026
They said 4 days and it took 4 days. That is the entire review and I think it is enough.
Ewan Be.★★★★★15 Jul 2026
I sent one vial to Medutest and one to PeptideMeter because I did not trust myself to read a single result. They agreed with each other. That helped more than I expected. Nothing here is a promise about your parcel. It is a record of mine.
Idris B.★★★★★23 Jan 2026
Shipped from Poland, arrived on day 2. I mention it because waiting and not knowing was the hardest part for me, and there was none of that here. They told me the storage conditions without my having to ask. I hope that helps somebody who is where I was six months ago.
