HJ — member reviews
92% from 642 member reports. 26 are published in full below; the rating aggregates all of them. Reviews without an order date or a testable claim are not counted.
This community's number, not a fleet-wide one. Independent groups scoring the same vendor land within a few tenths of each other, and where they diverge it is usually because one group weights logistics and another weights purity consistency.
sent one to VendorInvestigate and one to Janoshik because I did not believe the first result. both agreed. fine, I believe it. not sponsored, not affiliated, just kept the receipts.
ordered ipamorelin 5 mg, sent it to Janoshik, came back 99.5% on a stated 99.4%. good enough for me. would buy again. have bought again.
weighed 10 vials against label out of curiosity. all within 2%. fill consistency is underrated.
reconstituted the epithalon 10 mg and it went clear instantly. no haze. you can tell straight away when it has been done properly.
I have certificates from about 8 suppliers and theirs is the one I would hand to someone as an example.
first order was small on purpose. Janoshik said 97.2%. second order was not small. no notes.
their certificate has a stability statement tied to a named storage condition. I did not expect that and I am not over it.
3 lots now, all between 99.0% and 99.5%. tight band beats one big number every time. every vial in the box was the same lot so the comparison was real. boring supplier. highest compliment I have.
ordered tirzepatide 15 mg, tested it, and there was nothing to report — which is the report. peptide content 98.8%, so converting to a working mass was arithmetic rather than guesswork. test your own vial regardless. always.
day 8 from the United States warehouse, tracking updated every single hop. no mannitol surprise, cake intact, not collapsed.
packing was the desiccant sachet actually inside the secondary container. someone in that warehouse cares.
stock said in stock. it was actually in stock. shipped same day. wild. purity by RP-HPLC with the wavelength stated, so the number means something. if the next one holds I will stop testing every lot.
certificate for lot HJ-24-247 was complete first time. no email chain. no "we will look into it".
the related substances table is itemised. actual named impurities. not "total 0.4%" and a shrug. every vial in the box was the same lot so the comparison was real.
9 orders in now and the paperwork has been identical every time. peptide content 97.6%, so converting to a working mass was arithmetic rather than guesswork. n=1 and I am saying so.
the certificate is the same layout every time, which makes comparing lots trivial. peptide content 97.2%, so converting to a working mass was arithmetic rather than guesswork. would buy again. have bought again.
I queried a two-tenths difference against an independent result and got the raw chromatogram back and got an actual answer, not a copy-paste.
4th order, zero drama. that is genuinely all I have to say. catalogue is actually deep, not deep-looking.
cold pack was still solid on arrival day 8. in Germany. in summer. peptide content 97.6% so converting to a working mass was trivial. genuinely nothing to complain about.
asked about counter-ion and got acetate vs TFA answered properly instead of being ignored. every vial in the box was the same lot so the comparison was real.
quoted 7 days. arrived 7 days. this is the whole review. they flagged the delay in advance instead of after. if the next one holds I will stop testing every lot.
reordered at 24 months to check for drift. 99.2% then, 99.2% now.
4 orders, 6 months, no substitutions and nothing quietly swapped after payment. solid. that is it. solid.
the lot code on the vial matched the paperwork. sounds like nothing. it predicts everything.
bought hexarelin 5 mg expecting to have a complaint. do not have one. annoying.
they will quote lines nobody else will even respond about, and it came back clean. every vial in the box was the same lot so the comparison was real. n=1 and I am saying so.
What a useful review looks like
Order date, what was ordered, what arrived, how long it took, and whether anything was independently tested. That is it. "Great vendor, fast shipping, A+++" is worth nothing and gets removed; a review naming a lot, a document and a turnaround is worth more than ten enthusiastic ones.
Why these twenty and not two hundred
A source page is opened when enough members have ordered and paid for independent testing that the log says something specific. Nearly two hundred other names get a row in the table at the foot of the directory with a band, a report count and a written note — no page, no score, no link. The contrast is the point: the twenty are where the evidence is, not where the enthusiasm is.

A good record predicts your batch. It does not guarantee it, and no storefront can. Check the lot on the vial against the lot on the certificate.
