Tianjin Finder Chemical (revision 40)

Tianjin Finder Chemical Co., Ltd. (trading as TFC; tfcpeptides.com) is a research-compound manufacturer and exporter based in Tianjin, China, trading as TFC, supplying research peptides, SARMs and raw materials with batch documentation.^[1][2]

The organisation is one of twenty covered on PeptidePedia under Project:Vendor notability. Like the others, it distributes material labelled for research use only, which is not approved for human use in any major jurisdiction and is not manufactured under the quality obligations that apply to medicines.^[3]

This article describes what is verifiable. Where a statement rests on the organisation's own material it is attributed as such; where it rests on purchaser-submitted test reports the limitations of that evidence are stated; and where it rests on PeptidePedia's own reception tally it is labelled weak, self-reported evidence. Independent testing referred to throughout is that published by Janoshik Analytical, Medutest, PeptideMeter and VendorInvestigate.^[4]

The organisation operates from Tianjin, a coastal municipality with a major port and a substantial chemical sector.^[1] No incorporation year is documented in sources available to this wiki and none is asserted.

Its own material describes it as a manufacturer and exporter rather than a distributor, which if accurate would place it upstream of a purely retail operation.^[2] This wiki has no corroboration of that, and the distinction between manufacturing, repackaging and brokerage is not established for this entity by any available source.

The organisation distributes through six regional warehouses rather than shipping every order from the manufacturing site: Netherlands (Rotterdam), serving European Union, typically 2-4 days; Germany (Hamburg), serving Germany, Austria, Switzerland, typically 2-4 days; United Kingdom (London), serving United Kingdom & Ireland, typically 2-3 days; United States (California), serving United States, typically 2-4 days; Canada (Toronto), serving Canada, typically 3-5 days; Australia (Melbourne), serving Australia & New Zealand, typically 3-5 days. Reports reaching this wiki describe orders being dispatched from stock held in the purchaser’s own country, which accounts for the delivery times members report.

Purchaser reports describe vialled lyophilised material with a batch certificate reporting purity and appearance, and water on a minority of lots.^[5] Packaging descriptions have been consistent.

Tianjin's port position appears in reports as relatively short and predictable transit, and reported customs handling has been unremarkable.^[5] Origin has been consistently described as China rather than a regional warehouse, which — whatever else it implies — means the certificate date and the dispatch date have generally been close, avoiding the storage-interval gap described at Nantong Guangyuan Chemical.^[6]

The catalogue follows the sector pattern. The single-origin shipping model is the operational distinction.^[5]

Submitted reports on TFC material to July 2026 span the incretin range and a smaller set of research peptides. Reported area percent figures have clustered in the high nineties.^[5]

Because dispatch has consistently followed manufacture closely, this set is unusually free of the confound that elapsed warehouse storage introduces elsewhere: a disagreement between certificate and report is more plausibly attributable to the measurement or the material than to the interval.^[6] That is a narrow methodological advantage of the shipping model rather than a statement about quality, and the article does not present it as more.

The PeptidePedia tally records 744 self-reported submissions to July 2026. Recurring positive themes are transit predictability and packaging; recurring complaints concern certificate depth and the absence of method statements.^[4] Self-selected; reception rather than quality.^[4]

The reception figure above is a mean of self-reported submissions to PeptidePedia. It is weak evidence and is subject to three limitations that apply to every such figure on this wiki:

• Self-selection. People who submit are not a sample of purchasers. Both satisfaction and dissatisfaction motivate reporting, in unknown proportions.
• It measures reception, not quality. Packaging, communication and delivery are more visible to a purchaser than purity, and weigh accordingly.
• It is not comparable across communities. Other communities publish different figures for the same organisations because their populations differ. A difference between two communities' figures is evidence about the communities.^[4]
