Their storefront, not ours. Marked nofollow and sponsored, and nobody here is paid for it.
Shanghai, filed 2006, and the entry turns on one habit the rest of this ledger is inconsistent about: when a lot is superseded its certificate is left published beside the replacement, so the same line can be read across two lots instead of one best sample. A single certificate tells you about a day; two adjacent ones tell you whether the process moved. Four laboratories are run against the same lot and all four documents resolve from the lot code, so a member can pull two independently and compare — several here have. The two things logged against it are the dispatch model, which runs out of six regional warehouses so the vial in the box is not automatically the lot on the newest certificate, and the non-peptide catalogue: the oral-tablet and oil lines carry visibly thinner documentation than the lyophilised peptides do.

Regional stock, so orders ship inside the buyer’s own country.
- 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
- The superseded lot's certificate stays published next to the current one, so lot-to-lot reproducibility on a given line is something a buyer can read rather than take on trust
- Four laboratories against one lot — Janoshik, Medutest, PeptideMeter and VendorInvestigate — each document retrievable from the issuing service rather than only from the seller
- Peptide content is reported on a line separate from area percent, and water by Karl Fischer and endotoxin by LAL appear as issued rather than on request
- Six regional warehouses: name the lot code in the first email and ask which stock the order ships from, or the vial you get may not be the lot on the certificate you read
- Oral tablets and injectable oils are documented more thinly than the lyophilised peptide lines — ask for the full certificate on those before ordering, not after
- The catalogue desk answers same-day; custom synthesis quotes have taken three to four working days, so do not plan a bespoke order on catalogue timings

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.

Check the lot on the vial against the lot on the certificate when it arrives. A good record predicts your batch; it cannot guarantee it, and no storefront can.
