SGN — member reviews
95% from 636 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.
stock said in stock. it was actually in stock. shipped same day. wild. no mannitol surprise, cake intact, not collapsed. no notes.
weighed 11 vials against label out of curiosity. all within 2%. fill consistency is underrated. lines I actually reorder are the ones they keep in Poland.
the thing that sold me is peptide content being listed separately from purity. nobody does that and everybody should. peptide content 99.3% so converting to a working mass was trivial.
cold pack was still solid on arrival day 3. in the Netherlands. in summer. they gave the storage condition the stability statement was written against without being asked. paperwork is half of what you are paying for.
quoted 9 days. arrived 9 days. this is the whole review. invoice and vial and cert all agree on the lot.
ordered thymosin beta-4 5 mg, sent it to PeptideMeter, came back 97.8% on a stated 97.5%. good enough for me. happy. moving on.
sent one to Janoshik and one to VendorInvestigate because I did not believe the first result. both agreed. fine, I believe it. no mannitol surprise, cake intact, not collapsed. not sponsored, not affiliated, just kept the receipts.
reordered at 10 months to check for drift. 99.2% then, 99.2% now. lines I actually reorder are the ones they keep in Poland.
their raw tested 97.8% against a reseller vial of the same thing at 98.0%. going direct is not a vibe, it is a number. peptide content 99.5% so converting to a working mass was trivial.
3 lots now, all between 97.4% and 97.9%. tight band beats one big number every time. no upsell attached to the answer, which I noticed because it is unusual. no notes.
asked what storage condition the stability statement covered and got a straight answer. peptide content 99.0%, so converting to a working mass was arithmetic rather than guesswork. happy. moving on.
asked for an older lot certificate and it came back inside the hour. lot SGN-25-219 came back 98.3% on a stated 97.5%. n=1 and I am saying so.
their certificate has the gradient and the column chemistry. I did not expect that and I am not over it. paperwork is half of what you are paying for.
been buying survodutide 10 mg from them for 15 months. nothing has changed, which is the point. defaulting to them until something changes.
first order was small on purpose. PeptideMeter said 97.8%. second order was not small.
asked about counter-ion and got acetate vs TFA answered properly instead of being ignored. not sponsored, not affiliated, just kept the receipts.
asked for the batch record before paying and had the full document the same day. the reorder was identical to the first order in every respect I could check. would buy again. have bought again.
reconstituted the sermorelin 5 mg and it went clear instantly. no haze. you can tell straight away when it has been done properly. every vial in the box was the same lot so the comparison was real. paperwork is half of what you are paying for.
they told me about a 3 day delay before it happened. before. that is the bar and almost nobody clears it.
8th order, zero drama. that is genuinely all I have to say. happy. moving on.
day 5 from Australia warehouse, tracking updated every single hop. peptide content 97.9% so converting to a working mass was trivial.
the lot code on the vial matched the paperwork. sounds like nothing. it predicts everything. solid. that is it. solid.
split the order across two lots to compare. came back within 0.1 of each other. invoice and vial and cert all agree on the lot.
they will quote lines nobody else will even respond about, and it came back clean. no notes.
4 orders, 6 months, no substitutions and nothing quietly swapped after payment. research use only, obviously.
the related substances table is itemised. actual named impurities. not "total 0.4%" and a shrug. reply on the technical question came back same day. test your own vial regardless. always.
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.
Where SGN sells
Sangon Biotech (Shanghai) Co., Ltd. sells from its own storefront. The link below is marked nofollow and sponsored and is here so you can read what they say about themselves against what this page says about them. GLP Research Hub is paid nothing for it, and a link is not a recommendation.
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.
