TFS — member reviews
95% from 738 member reports. 12 are published in full below; the rating aggregates all of them. Reviews without an order date or a testable claim are not counted.
This community's number, not a fleet-wide one. Independent groups scoring the same vendor land within a few tenths of each other, and where they diverge it is usually because one group weights logistics and another weights purity consistency.
certificate for lot TFS-RT10-5306 sits next to the certificate for the lot it replaced, both still up. first supplier on this ledger where i could compare two lots of the same line without asking for anything.
four labs against one lot code and i pulled two of them from the services myself. both reconciled to the figure on the shop page.
peptide content on its own line, separate from area percent. that difference is several per cent on a tfa salt and almost nobody prints both.
no complaint about the material. a four because the order shipped out of a different warehouse than the certificate i had been reading, and i only learned that because i asked which lot was going in.
asked for water by karl fischer before ordering and it was already on the certificate as issued. so was endotoxin by lal.
shanghai to the uk in seven days, scanned at every hop, no dead intervals. dispatch note carried the lot string so the paperwork was filed before the box landed.
blind submission of bpc-157 10 mg to janoshik came back 99.1% against a stated 98%. i send blind and report what comes back.
oral tablet line came with a thinner certificate than the peptides did — purity and appearance, no dissolution. asked and got more, but it was not there by default.
reordered semaglutide at four months and read it against the older certificate still posted on the line. two tenths apart, same layout. no drift worth the name.
related substances itemised by retention time rather than totalled. you can see what the impurities are instead of being told there are 0.4% of them.
custom sequence quote took four working days while the catalogue desk answers the same afternoon. the build met its dates once quoted; plan around the gap.
lot code on the vial, on the certificate and on the invoice were the same string. sounds like the floor. across suppliers it is not.
What a useful review looks like
Order date, what was ordered, what arrived, how long it took, and whether anything was independently tested. That is it. "Great vendor, fast shipping, A+++" is worth nothing and gets removed; a review naming a lot, a document and a turnaround is worth more than ten enthusiastic ones.
Why these twenty and not two hundred
A source page is opened when enough members have ordered and paid for independent testing that the log says something specific. Nearly two hundred other names get a row in the table at the foot of the directory with a band, a report count and a written note — no page, no score, no link. The contrast is the point: the twenty are where the evidence is, not where the enthusiasm is.
Where TFS sells
Thermo Fisher Scientific (China) Co., Ltd. sells from its own storefront. The link below is marked nofollow and sponsored and is here so you can read what they say about themselves against what this page says about them. GLP Research Hub is paid nothing for it, and a link is not a recommendation.
