Their storefront, not ours. Marked nofollow and sponsored, and nobody here is paid for it.
Solid and unremarkable, which on this board is a compliment with evidence behind it. Shanghai, established 2019, results in the 98s, and the cold chain intact on every shipment members have reported. Current certificates name the method behind the purity figure, and they will produce it for an older lot if you ask.

the thing that sold me is peptide content being listed separately from purity. nobody does that and everybody should. test your own vial regardless. always.
support replied on a sunday with the batch record attached. on a sunday. they gave the storage condition the stability statement was written against without being asked. not sponsored, not affiliated, just kept the receipts.
split the order across two lots to compare. came back within 0.1 of each other. peptide content 97.2% so converting to a working mass was trivial. n=1 and I am saying so.
been buying sermorelin 5 mg from them for 14 months. nothing has changed, which is the point. the difference between their number and the lab number is smaller than method noise.
10 orders, 12 months, no substitutions and nothing quietly swapped after payment. if the next one holds I will stop testing every lot.
day 6 from France warehouse, tracking updated every single hop. customs paperwork right first time which is why it was fast. happy. moving on.
custom synth quote came back realistic and then they beat the date by 3 days. purity by RP-HPLC with the wavelength stated, so the number means something.
they will quote lines nobody else will even respond about, and it came back clean. gradient and column are both printed so you could reproduce it. defaulting to them until something changes.
asked about counter-ion and got acetate vs TFA answered properly instead of being ignored.
invoice, vial and certificate all agree on the lot number. support answered on the same working day with the document attached. test your own vial regardless. always.
shipped out of Ireland, landed day 6. no customs, no waiting, no chasing.
shipped from the regional warehouse and arrived in 8 days, domestic the whole way. the reorder was identical to the first order in every respect I could check. paperwork is half of what you are paying for.
asked for an older lot certificate and it came back inside the hour. the purity figure is stated by RP-HPLC with the wavelength named. happy. moving on.
blind submitted the TB-500 5 mg to VendorInvestigate, did not say whose it was. 99.5% vs 99.2% claimed. they gave the storage condition the stability statement was written against without being asked. solid. that is it. solid.
reconstituted the kisspeptin-10 5 mg and it went clear instantly. no haze. you can tell straight away when it has been done properly. reply on the technical question came back same day.
I have certificates from about 6 suppliers and theirs is the one I would hand to someone as an example. the difference between their number and the lab number is smaller than method noise.
the related substances table is itemised. actual named impurities. not "total 0.4%" and a shrug. catalogue is actually deep, not deep-looking. n=1 and I am saying so.
bought retatrutide 10 mg expecting to have a complaint. do not have one. annoying. customs paperwork right first time which is why it was fast.
their certificate has the residual-solvent screen. I did not expect that and I am not over it. purity by RP-HPLC with the wavelength stated, so the number means something.
3th order, zero drama. that is genuinely all I have to say. gradient and column are both printed so you could reproduce it. test your own vial regardless. always.
sent one to Medutest and one to PeptideMeter because I did not believe the first result. both agreed. fine, I believe it.
the lot code on the vial matched the paperwork. sounds like nothing. it predicts everything. the difference between their number and the lab number is smaller than method noise. research use only, obviously.
their raw tested 98.8% against a reseller vial of the same thing at 98.7%. going direct is not a vibe, it is a number. invoice and vial and cert all agree on the lot.
certificate for lot SWB-26-717 was complete first time. no email chain. no "we will look into it". customs paperwork right first time which is why it was fast.
reordered at 6 months to check for drift. 97.9% then, 97.9% now. genuinely nothing to complain about.
cold pack was still solid on arrival day 6. in Germany. in summer.

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.
