Where to buy SS-31 (Elamipretide) in the UK, and how to check it's real
To buy SS-31 in the UK from a seller whose testing you can actually verify, choose one of the 28 UK sellers that publish their own verifiable Janoshik certificate of analysis (of 320 active UK sellers, only 9% do). SS-31 is a synthetic mitochondria-targeting tetrapeptide studied in cellular-energy research. A newer compound where independent testing is scarcer, so a verifiable certificate carries more weight. 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 SS-31
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.

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 SS-31, 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 SS-31 and links to no shop; this is research-use-only information, not medical or dosing advice.
