Domestic dispatch from their stock in Australia. Straightforward, day 4, exactly as quoted.

One of the few places that will quote IGF-1 LR3 1 mg at all, and the synthesis came back clean on an independent check.

u/sten_rautio2025-06-02

Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.

Janoshik has now seen 7 of their lots through me. Not one has come back outside spec.

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

u/hamza_weiss2025-09-18

Consistent rather than flashy. Everything lands in the high nineties, and it lands there every time.

u/anya_moreau2026-05-20

First order, deliberately small, selank 10 mg only. Documentation, transit and a Medutest result at 97.6% all checked out, so the next one will not be small.

u/zeynep_mbeki2025-04-28

Weighed 4 vials from the tesamorelin 2 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.

u/kaia_kuusela2025-05-16

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

u/niels_yilmaz2025-11-14

8 lots logged now, purity 98.3 to 98.7%. A band that tight is worth more to me than one spectacular number.

Their warehouse in Germany carries the lines I reorder, so there is no wait on a factory run. Day 4 every time.

u/kaia_wojcik2025-11-06

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

u/fabio_ibarra2025-08-15

Second order from them, all cagrilintide 5 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.

u/aksel_jansen2025-06-07

Same lot documentation as the factory ships, but out of their warehouse in the United States, so it landed on day 3.

u/neha_falk2026-02-04

Documentation is complete and the numbers are steady. A dependable choice for routine work.

u/anjali_tamm2025-07-06

Ordered IGF-1 LR3 1 mg twice. Both vials reconstituted cleanly and both matched their certificates.

Shipped from their warehouse in Germany, arrived day 2, documentation complete.

u/hugo_norgaard2026-03-04

Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.

u/jonas_eriksen2026-06-23

The certificate for lot TFC-24-154 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.

Their raw material tested 97.9% against a reseller vial of nominally the same compound at 97.9%. Going direct is the whole argument.

u/enzo_petrescu2026-02-22

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/cesar_ivaturi2026-07-14

Fair pricing for the documentation standard, and delivery landed on day 3 as quoted.

u/milos_trevino2026-03-01

Submitted the tirzepatide 15 mg to Medutest blind, without telling them the source. 99.6% against a stated 99.4%. The number holds up when nobody knows whose vial it is.

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

u/nora_oyelaran2025-04-07

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

u/hamza_serrano2025-06-20

Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.

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 TFC sells

Tianjin Finder Chemical 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.
