Teodor S.★★★★☆
Steady supplier. PeptideMeter results have agreed with their stated figures on every lot I have submitted.
4.7
★★★★⯨A rating here summarises what members have said about ordering. It is not a safety rating and it cannot be one.
Tianjin Finder Chemical Co., Ltd., trading as TFC, based in Tianjin. Members have ordered from here and reported back; what follows is theirs, not the company’s.
What members have reported
Including the reports that do not flatter anybody.
Members describe ordering as straightforward. Transit sits in the one-to-three week band most of the time, and the cold pack usually arrives cold. The reports that matter most are the ones where something went wrong, and those are below with the rest.
Communication is described as quick and a little formulaic. Members who asked a precise question generally got a precise answer; members who asked an open one got a template.
The testing record, and its limits
TFC publishes third-party reports against catalogue items, and several members have commissioned their own testing rather than relying on those. Independent results have broadly matched the published figures.
What a purity figure proves is narrow. It tells you what proportion of the peptide present is the peptide you wanted. It says nothing about how much peptide is in the vial, and nothing about sterility. Those are separate measurements and they are not always supplied.
Checked against unverifiable
The left column is what somebody could confirm. The right column is what nobody can.
Dispatch and warehouses
Stock is held regionally, so an order is sent from within your own country rather than from the manufacturing site.
- Netherlands (Rotterdam) — European Union, 2-4 days
- Germany (Hamburg) — Germany, Austria, Switzerland, 2-4 days
- United Kingdom (London) — United Kingdom & Ireland, 2-3 days
- United States (California) — United States, 2-4 days
- Canada (Toronto) — Canada, 3-5 days
- Australia (Melbourne) — Australia & New Zealand, 3-5 days
Can be checked
- That the shop trades at tfcpeptides.com and gives Tianjin as its base
- That third-party reports exist for named catalogue items, and that members have independently reproduced some of them
- That members here have ordered, received, and reported back over a period of months
Cannot be checked
- Any relationship, or absence of one, between this shop and any similarly named company
- Chain of custody between manufacture and dispatch, including how long stock sat and at what temperature
- Sterility and endotoxin status of anything in a vial, which no purity panel addresses
Questions to ask before you order
Take these verbatim. The answers, and the non-answers, are informative.
- Can you send the certificate for the lot number printed on my vial, not a representative one?
- Does the certificate include peptide content by weight as well as purity?
- How was this stored between manufacture and dispatch, and for how long?
Member reports
Published in full, including the unimpressed ones.
Bruno★★★★☆
Documentation is complete and the numbers are steady. A dependable choice for routine work.
Priya★★★★☆
Domestic dispatch from their stock in the United States. Straightforward, day 4, exactly as quoted.
Dario K.★★★★★
No customs paperwork, no import wait — it came from their stock in Germany and arrived day 4.
Paloma I.★★★★☆
Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.
Bastian★★★★☆
Held locally in the United Kingdom, so the GHK-Cu 50 mg arrived on day 4 without an import step.
Bence G.★★★★★
Their warehouse in Germany had the TB-500 5 mg in stock and it shipped the same afternoon. Tracking never left the country.
Jonas M.★★★★★
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
Wanjiru★★★★☆
Everything about the order was routine in the best sense — quoted 4 days, arrived in 3.
Lukas★★★★★
Quoted 5 days, arrived in 5. Tracking updated at every hop from dispatch to door.
Katrin T.★★★★★
Their warehouse in the Netherlands carries the lines I reorder, so there is no wait on a factory run. Day 5 every time.
Zaid K.★★★★★
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
Kofi★★★★☆
Sensible packing, sensible timelines, and a certificate that says what it should. No notes.
Signe M.★★★★★
Moved here after two bad lots elsewhere. 6 orders in and the Medutest numbers have been flat every single time.
Aisha★★★★★
Arrived on day 4 against a quoted 5. Customs paperwork was right first time, which is why it moved that fast.
Mateusz★★★★★
6 lots logged now, purity 97.4 to 97.5%. A band that tight is worth more to me than one spectacular number.
Kenji T.★★★★★
Queried the related-substances total on lot TFC-25-821; they came back with method, column and detection limit. That depth is rare.
Arne B.★★★★★
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
Elodie K.★★★★★
Dispatched from their warehouse in the United States rather than from the factory, so the ipamorelin 5 mg was with me on day 4.
Amara★★★★★
The certificate for lot TFC-24-779 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
Anders O.★★★★★
Fifth order from them, all NAD+ 500 mg. Sent one vial from each to PeptideMeter and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
Zaid N.★★★★★
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
Katrin D.★★★★★
Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.
Astrid B.★★★★☆
Third order and it went the same way as the first two. Predictable in the way you want a supplier to be.
Bianca R.★★★★★
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
Katrin K.★★★★★
Peptide content reported at 99.6% alongside the purity figure, so I could convert straight to a working mass.
