Quality & Testing
TFC is a Janoshik-tested manufacturer, with additional verification from PeptideMeter Analytics, Medutest, VendorInvestigate, and the GLP1Forum community verification program. As a direct manufacturer, TFC publishes batch-level HPLC purity and mass spectrometry identity data, and the community routinely confirms these results through independent Janoshik and PeptideMeter testing.
Janoshik-Tested Manufacturer: TFC submits production batches to Janoshik Analytical for independent HPLC and mass spectrometry analysis, and community members have repeatedly reproduced those purity figures via their own Janoshik and PeptideMeter tests. Combined with PeptideMeter, Medutest, VendorInvestigate, and GLP1Forum verification, this gives TFC one of the more thoroughly documented testing profiles among vendors tracked by The GLP Lounge.

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 raw materials (Semaglutide + BPC-157 powder)
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 order from TFC and I'm impressed. Retatrutide tested at 98.7% via Janoshik, right in line with the COA. Used the US warehouse this time and it arrived in 4 days, fully tracked. Paid with crypto for the 10% discount, which made the pricing very competitive. TFC being a direct manufacturer with full HPLC and MS documentation gives me confidence. Will be ordering again.

Product: BPC-157 5mg x 20 vials + TB-500 10mg x 10 vials (UK Warehouse)
Large healing peptide order from TFC's UK warehouse. BPC-157 at 99.2% and TB-500 at 98.2% on Janoshik. Royal Mail delivered in 2 days. As a direct manufacturer, TFC's batch consistency on their flagship peptides is excellent — all 20 BPC vials were uniform with clean lyophilization. The COAs matched the PeptideMeter published grades. Strong choice for UK-based researchers wanting domestic shipping with full documentation.

Product: Semaglutide 10mg x 5 vials (EU Warehouse)
Healthcare professional review: TFC's documentation meets professional standards. HPLC chromatograms, mass spec identity, and endotoxin results all included with the COA. Semaglutide tested at 98.6%, independently confirmed via Janoshik. EU warehouse delivery in 3 days from what looked like a Netherlands hub. As a direct manufacturer, TFC clearly controls their own quality chain. Third order, all consistent.

Product: Semax 10mg x 10 vials + Selank 5mg x 10 vials (Tianjin Direct)
Solid nootropic peptide order from TFC. Selank tested at 98.9% but Semax came in at 97.8%, which earned a PeptideMeter B+ rather than an A. Both still usable and matched within analytical variation of the COA. Tianjin direct shipping took 11 days to reach me, fully tracked the whole way. Four stars only because the Semax purity could be a notch higher — everything else, including documentation and packaging, was excellent.

Product: Tirzepatide 15mg x 5 vials + Ipamorelin 5mg x 10 vials (Canada Warehouse)
Canada warehouse delivery in 3 days via Canada Post, no customs issues. Tirzepatide at 99.1% and Ipamorelin at 99.0% on Janoshik — both excellent. TFC's status as a direct manufacturer really shows in the consistency. The Medutest and VendorInvestigate verifications, on top of Janoshik and PeptideMeter, made me comfortable trying a larger order. Crypto discount applied cleanly. Recommended for Canadian researchers.

Product: Semaglutide 10mg x 5 vials (Australia Warehouse)
Australian warehouse delivery in 3 days via StarTrack. Semaglutide at 98.6% purity on Janoshik. For Australian researchers, a local warehouse option is invaluable given strict import rules. TFC joins the short list of vendors with Australian warehousing, and as a direct manufacturer their GLP-1 product was excellent with thorough documentation. The COA batch number matched the PeptideMeter listing exactly. Will order again.
