SGN — member reviews
97% 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.
Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.
Costed them per mg against three other suppliers on the same selank 10 mg spec. Competitive on price and clearly ahead on documentation.
Reconstituted the tesamorelin 2 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
Domestic dispatch from their stock in Australia. Straightforward, day 3, exactly as quoted.
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
Moved here after two bad lots elsewhere. 7 orders in and the Janoshik numbers have been flat every single time.
Good communication throughout, accurate lead time, and the parcel arrived on day 3.
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 9 hours.
Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.
Quoted 5 days, arrived in 4. Tracking updated at every hop from dispatch to door.
Steady supplier. Janoshik results have agreed with their stated figures on every lot I have submitted.
Pleased to find they hold stock in the United Kingdom. Domestic dispatch, day 3, no customs step at all.
Regional stock makes the difference — dispatched within Australia, day 4, cold pack still hard on arrival.
Their warehouse in the United States carries the lines I reorder, so there is no wait on a factory run. Day 5 every time.
Certificate claimed 99.2% on lot SGN-25-891. PeptideMeter came back 99.3%. On an independent column that is as close to agreement as this gets.
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
Weighed 3 vials from the thymosin alpha-1 5 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
Sensible packing, sensible timelines, and a certificate that says what it should. No notes.
Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.
Ordered on a Monday from their warehouse in the United States and it was here by day 5. That is the whole case for regional stock.
Seventh order from them, all epithalon 10 mg. Sent one vial from each to Janoshik and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
Arrived on day 3 against a quoted 4. Customs paperwork was right first time, which is why it moved that fast.
Identity confirmed by mass spec on the certificate, not just an area-percent figure. Both questions answered on one page.
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 three-star review explaining precisely what went wrong and how it was handled is worth more than ten five-star ones.
Why the negative ones stay up
A directory of nothing but praise is a marketing brochure. Every source page here carries the disappointing results as prominently as the good ones, and the vendors near the top of the ranking are there because their bad entries are few and old, not because there are none.
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.
