Held locally in Australia, so the PT-141 10 mg arrived on day 2 without an import step.

What the room says
A life-sciences reagent house that also does peptides, which shows in the paperwork culture. #lab-requests has used them as a source of reference material for pooled submissions because the documentation is unambiguous about what is in the bottle.

2024-02-01slow.taper — i have never had a problem i could not resolve with SGN, which is a low bar and a lot of suppliers fail it#vendor-talk2024-11-25group_buy_gwen — Janoshik came back 98.1 on one lot and 99.4 on the next from the same SGN, both fine#retatrutide2025-02-07LC_MS_Lena — what a 97 tells you is that the synthesis or the purification ran looser than a 99. it is a process signal more than a product signal#vendor-verification2025-02-23knees_first — or two labs, or two years, or two compounds. an aggregate row flattens all of that#test-results2025-03-13retention_time — good place to leave it#other-peptides2025-04-21noct.titrate — unrelated but PeptideMeter came back 98.6 on a SGN lot, which tells you whats in the vial and nothing about whether it works#other-peptides2025-07-01vial_ledger — like this one, which is mine and still not great#test-results2025-08-07ferrous_ash — SGN has been consistent for me across 2 orders which is what i actually want, i think#vendor-talk2025-10-11ten_of_ten — anyone compared SGN and ERP on the same compound#vendor-talk2025-11-10turnaround_tam — my sheet has 2 lots from SGN with a spread under a point, which is tight, thats one data point#test-results2026-01-18thank_you_year_on — janoshik-J24-11407-sgn-sema.pdf#coa-reading2026-02-01sgp_subq — budget the test into the order. thats the single most repeated piece of good advice on this whole site#asia2026-03-04warsaw_vial — which is why the channel keeps saying content data is thin. it is not that nobody tests, it is that everybody buys the cheap test#test-results2026-04-04orfor_watch — my Janoshik report on the SGN vial came back 99.2 against a certificate saying 98.6#semaglutide2026-05-20deamidation — that is a lower bar than it should be and most people clear it, but they clear it well#vendor-talk2026-06-29typosquat_tay — anyone compared their Janoshik purity across two different SGN lots#retatrutide

Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.
chiara_a★★★★★2025-08-14
First order, deliberately small, cagrilintide 5 mg only. Documentation, transit and a Janoshik result at 99.0% all checked out, so the next one will not be small.
solene_p★★★★★2026-02-08
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 3 hours.
hugo_f★★★★★2026-01-14
Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.
marta_e★★★★★2025-10-26
Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.
salma_n★★★★★2026-07-26
Their warehouse in the United Kingdom had the thymosin alpha-1 5 mg in stock and it shipped the same afternoon. Tracking never left the country.
amira_ki★★★★★2026-04-10
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
kian_h★★★★★2026-03-08
One of the few places that will quote MOTS-c 10 mg at all, and the synthesis came back clean on an independent check.
petra_b★★★★★2026-03-02
Arrived on day 3 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.
emil_n★★★★★2026-03-17
Certificate claimed 99.5% on lot SGN-24-955. PeptideMeter came back 99.8%. On an independent column that is as close to agreement as this gets.
rosa_d★★★★☆2026-07-22
Ordered semaglutide 10 mg twice. Both vials reconstituted cleanly and both matched their certificates.
signe_s★★★★★2025-10-06
Peptide content reported at 99.8% alongside the purity figure, so I could convert straight to a working mass.
tuva_v★★★★★2026-04-04
Regional stock makes the difference — dispatched within Australia, day 2, cold pack still hard on arrival.
bianca_o★★★★★2026-07-06
The tirzepatide 10 mg arrived on day 5 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.
ignacio_o★★★★☆2025-02-07
Steady supplier. Medutest results have agreed with their stated figures on every lot I have submitted.
diego_r★★★★★2026-04-23
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
zaid_m★★★★★2025-09-04
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
ravi_a★★★★★2026-04-14
No customs paperwork, no import wait — it came from their stock in the United States and arrived day 2.
joaquin_kj★★★★★2026-05-06
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
saskia_m★★★★★2025-03-28
Reconstituted the tirzepatide 10 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
viktor_a★★★★★2025-11-28
Dispatched from their warehouse in Australia rather than from the factory, so the selank 10 mg was with me on day 4.
kasper_t★★★★★2026-05-17
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
nadia_sa★★★★★2026-01-05
Sixth order from them, all semaglutide 10 mg. Sent one vial from each to Medutest and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
amira_d★★★★★2025-12-02
Their warehouse in Germany carries the lines I reorder, so there is no wait on a factory run. Day 5 every time.
vito_b★★★★★2026-02-25
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.

Where SGN sells
Sangon Biotech (Shanghai) Co., Ltd. sells from its own storefront. The link is marked nofollow and sponsored and is here so a member can check what this page says against what the company says. The room is paid nothing for it and a link is not a recommendation.
Whatever the storefront says, check the lot on the vial against the lot on the certificate before you use anything.
Fairness note
Criticism on this page is specific and evidenced. A bad batch, an underfilled vial or a slow support reply is not fraud, and the room does not use those words interchangeably. Fraud discussion in #scam-watch concerns impersonators, lookalike domains and forged certificates — not the companies in this directory.
