Xi’an, established 2016. The material has been in band on every independent test anybody has run, across four tests and four compounds, and the pricing sits below the Shanghai cluster for comparable work. Nothing has ever been substituted without being asked first, which is a smaller thing than it sounds until it happens to you somewhere else.

ordered tirzepatide 15 mg, sent it to PeptideMeter, came back 98.9% on a stated 98.7%. good enough for me.
they will quote lines nobody else will even respond about, and it came back clean. catalogue is actually deep, not deep-looking. defaulting to them until something changes.
split the order across two lots to compare. came back within 0.1 of each other. reply on the technical question came back same day.
sent one to Janoshik and one to VendorInvestigate because I did not believe the first result. both agreed. fine, I believe it. customs paperwork right first time which is why it was fast. happy. moving on.
bought GHRP-2 5 mg expecting to have a complaint. do not have one. annoying. lines I actually reorder are the ones they keep in the Netherlands. no notes.
reordered at 15 months to check for drift. 98.3% then, 98.3% now. they gave the storage condition the stability statement was written against without being asked.
cold pack was still solid on arrival day 8. in Germany. in summer.
they told me about a 2 day delay before it happened. before. that is the bar and almost nobody clears it.
asked for the batch record before paying and had the full document the same day. batch, date, method and impurity table all present on one page. defaulting to them until something changes.
first order was small on purpose. Medutest said 99.5%. second order was not small. boring supplier. highest compliment I have.
6th order, zero drama. that is genuinely all I have to say. purity by RP-HPLC with the wavelength stated, so the number means something. defaulting to them until something changes.
the thing that sold me is peptide content being listed separately from purity. nobody does that and everybody should. no upsell attached to the answer, which I noticed because it is unusual. would buy again. have bought again.
I asked about storage before shipping in July and they moved the dispatch to a Monday unprompted and got an actual answer, not a copy-paste. happy. moving on.
asked about counter-ion and got acetate vs TFA answered properly instead of being ignored. no notes.
reconstituted the PT-141 10 mg and it went clear instantly. no haze. you can tell straight away when it has been done properly.
11 orders, 10 months, no substitutions and nothing quietly swapped after payment. paperwork is half of what you are paying for.
I have certificates from about 10 suppliers and theirs is the one I would hand to someone as an example. purity by RP-HPLC with the wavelength stated, so the number means something.
their certificate has a stability statement tied to a named storage condition. I did not expect that and I am not over it. no upsell attached to the answer, which I noticed because it is unusual. happy. moving on.
day 3 from the Netherlands warehouse, tracking updated every single hop.
weighed 3 vials against label out of curiosity. all within 2%. fill consistency is underrated. mass variation across the box was under 2%.
been buying ipamorelin 5 mg from them for 10 months. nothing has changed, which is the point.
sent a vial to Medutest out of habit. 99.8% against a claimed 99.0%. nothing in the box rattled and nothing had shifted. paperwork is half of what you are paying for.
their raw tested 99.0% against a reseller vial of the same thing at 98.9%. going direct is not a vibe, it is a number.
shipped out of Australia, landed day 5. no customs, no waiting, no chasing. boring supplier. highest compliment I have.
lot MKM-25-773 tested 97.6%. certificate said what the vial said which said what the invoice said. invoice and vial and cert all agree on the lot.
shipped from the regional warehouse and arrived in 9 days, domestic the whole way. lot MKM-24-672 was fine on test and the trace was clean at the baseline. paperwork is half of what you are paying for.

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.
