A real catalogue chemistry company that people keep doubting precisely because it looks like a normal supplier rather than a peptide boutique. Est. 2004, Shanghai. The reagent-side reputation carries over: order system behaves like you are dealing with a distributor, which you are.

What holds up
  • Genuine catalogue chemistry operation, not a repackager
  • Order system behaves like a real distributor — order numbers, invoices, the boring stuff

What to watch
  • Support answers chemistry questions well and dosing questions not at all, which is correct but surprises people
  • Some catalogue items are research reagents with no peptide COA at all.

u/anders_karlsen2026-04-23

Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.

u/amara_haddad2025-12-09

Costed them per mg against three other suppliers on the same selank 10 mg spec. Competitive on price and clearly ahead on documentation.

u/kian_ferreira2025-06-14

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.

u/bastian_eriksen2026-02-17

Domestic dispatch from their stock in Australia. Straightforward, day 3, exactly as quoted.

u/yara_boateng2026-03-19

Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.

u/oskar_kaufmann2025-09-04

Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.

u/ismael_varga2025-12-22

Moved here after two bad lots elsewhere. 7 orders in and the Janoshik numbers have been flat every single time.

u/tobias_barros2025-11-01

Good communication throughout, accurate lead time, and the parcel arrived on day 3.

u/teodor_lokken2026-02-01

Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 9 hours.

u/emeka_delgado2026-01-15

Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.

u/meera_oyelaran2026-06-17

Quoted 5 days, arrived in 4. Tracking updated at every hop from dispatch to door.

u/kenji_vasquez2026-06-05

Steady supplier. Janoshik results have agreed with their stated figures on every lot I have submitted.

u/ruben_almeida2026-04-03

Pleased to find they hold stock in the United Kingdom. Domestic dispatch, day 3, no customs step at all.

u/oskar_malinowski2026-07-21

Regional stock makes the difference — dispatched within Australia, day 4, cold pack still hard on arrival.

u/hassan_nilsen2025-05-11

Their warehouse in the United States carries the lines I reorder, so there is no wait on a factory run. Day 5 every time.

u/jonas_cardoso2025-12-20

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.

u/lina_dziedzic2026-03-03

Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.

u/rosa_sandvik2025-02-10

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.

u/ismael_eriksen2026-06-26

Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.

u/hugo_bergstrom2026-02-20

Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.

u/kofi_balogun2026-05-14

Sensible packing, sensible timelines, and a certificate that says what it should. No notes.

u/nadia_trevino2026-04-04

Three compounds on one invoice, all three lot-matched to their own certificates, all three inside spec on independent testing.

u/katrin_marchetti2026-06-19

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.

u/runa_wikstrom2026-06-14

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.

u/ewan_marchand2025-02-17

Arrived on day 3 against a quoted 4. Customs paperwork was right first time, which is why it moved that fast.

u/chidi_roos2026-05-05

Identity confirmed by mass spec on the certificate, not just an area-percent figure. Both questions answered on one page.

How a source page works

A source page is a record, not a review. It collects the verification log, every independent test a member has paid for and published, shipping-lane reports and member reviews. Ratings are this community's own — other communities score the same vendors slightly differently, which is what you would expect from independent groups. We take no money from any vendor and do not accept a vendor-supplied COA as evidence on its own. Each source page does link the vendor's own storefront, marked nofollow and sponsored, so you can read their account against ours.

Where SGN sells

Sangon Biotech (Shanghai) Co., Ltd. sells from its own storefront. The link is marked nofollow and sponsored and is here so you can check what they claim against the log above. Nobody here is paid 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.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
