Where to buy MOTS-c in the UK, and how to check it's real
To buy MOTS-c in the UK from a seller whose testing you can actually verify, choose one of the 30 UK sellers that publish their own verifiable Janoshik certificate of analysis (of 326 active UK sellers, only 9% do). MOTS-c is a mitochondrial-derived peptide studied in metabolic research. It is a newer, less commoditised compound, so genuinely independent testing is scarcer and a verifiable certificate matters even more. Purity and identity cannot be judged by eye, so an independent certificate you can check is the only real proof of what is in the vial.
The one test that matters for MOTS-c
Ignore the marketing. The question is simple: does the seller publish a verifiable Janoshik certificate that names the seller itself as the client? If it does, you can confirm an independent lab tested that batch. If it shows an in-house document, a borrowed certificate, or "COA on request", you cannot. Learn the two-minute check in how to verify a Janoshik COA.

Each entry is confirmed directly from that vendor's own-name Janoshik report on the laboratory's own site. This list is not exhaustive: a verified vendor not shown may also test MOTS-c, and compounds are added as each certificate is confirmed.
An honest note: a verifiable certificate proves a sample of a batch was tested, not that the specific vial you receive matches it, see what this can and can't tell you. The Peptide Watch sells no MOTS-c and links to no shop; this is research-use-only information, not medical or dosing advice.
