Their storefront, not ours. Marked nofollow and sponsored, and nobody here is paid for it.
Shenzhen, established 2003, and an API and contract-manufacturing operation that sells research quantities alongside the commercial work rather than a peptide shop that grew into one. The documentation reads accordingly: method line, itemised related substances and a stability statement on the certificates members have posted here. Across five independent tests on four different services the claimed figure has never been the higher number, which is the only consistency this board has learned to trust.

- Five independent tests across four services and the claim has never come back the higher number
- Certificates carry the method line and an itemised related-substances table as standard, not on request
- Catalogue runs past 350 research compounds and the unusual lines get quoted rather than ignored
- Coastal origin, so the Shenzhen lanes are the quick ones — ask which of your lines is held regionally rather than dispatched from the factory
- The certificate carries batch, date of analysis, method line, related substances and a stability statement; water content comes back on request for any lot
- Minimum order on the research catalogue is a single vial and API quantities are quoted separately — ask for the batch record for the lot they would actually ship you

ordered retatrutide 10 mg and sent it to Janoshik. 98.4% on a stated 98.0%. third time their claim has come back low rather than high.
asked for the batch record before paying and had the full document the same afternoon. batch, date of analysis, method line and the impurity table all on one page. paperwork is half of what you are paying for.
they answer a technical question with the actual method. column, gradient, wavelength. no upsell attached to the answer, which I noticed because it is unusual.
day 8 to the UK, tracking updated every single hop. customs paperwork right first time which is why it was fast. no notes.
catalogue is actually deep, not deep-looking. asked about three lines nobody else would even respond about and got prices and lead times for all three.
split the order across two lots to compare. 98.3 and 98.2. that is method noise, not a difference.
peptide content is listed separately from purity on the certificate. nobody does that and everybody should.
reconstituted the ipamorelin 5 mg and it went clear instantly. no haze, nothing floating. you can tell straight away when it has been done properly.
4th order, zero drama. that is genuinely all I have to say. boring supplier. highest compliment I have.
they told me about a 3 day delay before it happened. before. that is the bar and almost nobody clears it. second order with them and the same again, so it is not a one off.
lot HYB-25-914 tested 98.1%. certificate said what the vial said which said what the invoice said. invoice and vial and cert all agree on the lot.
asked about storage before ordering and they moved the dispatch to a Monday unprompted so it would not sit in a depot over the weekend. got an actual answer, not a copy-paste.
weighed 4 vials against label out of curiosity. all within 2%. fill consistency is underrated.
their raw tested 98.6% against a reseller vial of the same thing at 98.2%. going direct is not a vibe, it is a number.
asked about counter-ion and got acetate vs TFA answered properly instead of being ignored. defaulting to them until something changes.
their certificate has a stability statement tied to a named storage condition. I have certificates from about 10 suppliers and theirs is the one I would hand to someone as an example.
sent one vial to Medutest and one to PeptideMeter because I did not believe the first result. both agreed inside 0.2. fine, I believe it.
reordered at 11 months to check for drift. 98.2% then, 98.3% now. nothing has changed, which is the point.
this is an actual manufacturing operation rather than three people and a courier account, and you can tell from the documentation before you can tell from the vial.
nothing in the box rattled and nothing had shifted. vials labelled with the lot, matching the certificate. happy. moving on.
shipped out of Shenzhen and landed day 9 in Australia, domestic the whole last leg. no customs, no chasing.
first order was small on purpose. VendorInvestigate said 97.9% on a claimed 97.5%. second order was not small.
asked for the water content on an older lot and it came back the same day with the analysis attached. no arguing about it.
6 orders, 8 months, no substitutions and nothing quietly swapped after payment. happy. moving on.
purity by RP-HPLC with the wavelength stated, so the number means something. would buy again. have bought again.
the lead time quoted at checkout was the one I actually got, to the day. that is rarer than it should be.

Check the lot on the vial against the lot on the certificate when it arrives. A good record predicts your batch; it cannot guarantee it, and no storefront can.
