Product: Tirzepatide 15mg x 5 vials (Tianjin Direct)
TFC tirzepatide tested at 99.1% via Janoshik, matching the COA exactly. Tianjin direct shipping reached the US in 10 days, fully tracked. Excellent documentation.

Product: Semaglutide 10mg x 5 vials (Tianjin Direct)
Semaglutide at 98.4% on my PeptideMeter test — solid. TFC is a real manufacturer, not a reseller, and their COAs are thorough. Shipping was a touch slow from China but everything arrived intact.

Product: Bulk BPC-157 raw powder + TB-500 raw powder (Tianjin Direct)
Bulk raw-material order from TFC came with full HPLC and MS data. Tianjin Finder Chemical has been consistent across three orders — Janoshik and PeptideMeter results both line up with what they publish.

Product: Retatrutide 10mg x 5 vials (US Warehouse)
First TFC order through their US warehouse and it shipped fast — 3 days to California. Retatrutide came back at 98.9% on Janoshik, matching the COA in the box. The fact that TFC is a real Tianjin manufacturer with their own HPLC and MS documentation is what sold me. PeptideMeter has them registered as a verified vendor and the batch number lined up with the published grade. Discreet packaging, full tracking. Adding them to my rotation.

Product: BPC-157 5mg x 10 vials + Ipamorelin 5mg x 10 vials (UK Warehouse)
UK warehouse delivery in 2 days via Royal Mail. BPC-157 tested at 99.2% and Ipamorelin at 99.0% via Janoshik — excellent results on both. TFC's healing peptide line is consistently high purity and the COAs match what PeptideMeter publishes. As a full-range manufacturer they had everything I needed in one order, including a couple of oral compounds. Documentation included HPLC chromatograms and MS data per vial batch. Reliable vendor for UK-based research.

★★★★☆
Product: Semax 10mg x 10 vials + GHK-Cu 50mg x 5 vials (Tianjin Direct)
Ordered some of TFC's nootropic and cosmetic peptides direct from Tianjin. Semax tested at 97.7% (PeptideMeter B+) and GHK-Cu at 97.6%. Acceptable but not the very top tier for these specific peptides, which is why I'm giving four stars. That said, TFC's documentation was complete with full COA, HPLC, and MS, and the batch numbers matched their published results exactly. Shipping took about 12 days from China but was fully tracked. For the price and the manufacturer-direct sourcing, still a good value.

Product: Semaglutide 5mg x 10 vials (EU Warehouse)
Healthcare professional review: TFC's documentation meets professional standards. HPLC chromatograms, mass spec identity confirmation, and endotoxin results all included. Semaglutide tested at 98.6% purity, independently confirmed against my own PeptideMeter submission. EU warehouse delivery was 3 days from what looks like a Netherlands hub. Tianjin Finder Chemical being a genuine manufacturer rather than a reseller is clear from the consistency of their batch records. Second order, both excellent.
Canada warehouse delivery in 3 days via Canada Post, no customs issues. MK-677 powder tested at 99.3% on Janoshik — outstanding. TFC's full-range catalog is genuinely useful: I was able to get an oral compound and an injectable oil prep in the same order alongside peptides. Everything came with proper COA and HPLC/MS data. Tianjin Finder Chemical has earned my repeat business through consistent quality and complete documentation. Recommended for Canadian researchers wanting a one-stop manufacturer.

Product: Tirzepatide 10mg x 10 vials + Semaglutide 10mg x 10 vials (Australia Warehouse)
Australian warehouse delivery in 3 days via StarTrack — invaluable given our strict import rules. Tirzepatide at 99.0% and semaglutide at 98.5% on Janoshik, both cross-checked on PeptideMeter. TFC joins the short list of vendors with Australian warehousing. The COAs, HPLC chromatograms, and MS data were all there and the batch numbers matched the published grades. As a genuine Tianjin manufacturer their GLP-1 line is consistently well-made. Will keep ordering.
