# MOTS-c vs SS-31?

MOTS-c and SS-31 are different research compounds. MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA; SS-31 is elamipretide. They are not interchangeable and there is no published head-to-head comparison. Sable sells both for research use only, each with a lot-specific CoA.

## MOTS-c

a 16-amino-acid peptide encoded in mitochondrial DNA, studied in cellular metabolism models.

## SS-31

elamipretide, a mitochondria-targeted tetrapeptide studied in mitochondrial research.

## How prices are checked

we compare our price daily against genuine, established UK suppliers only (not marketplaces or unverifiable listings) and guarantee the lowest UK price. If you find a lower like-for-like price from such a supplier, we match it. In our 10 October 2026 snapshot of 16 UK-facing retailers, the median list price for 10 mg was £24.99 (range £14.97 to £35.00); Sable listed it at £14.97. Method and seller types are explained on the pricing methodology page.

## Documentation

Every lot has its own Certificate of Analysis and every vial carries a printed lot number, so the paperwork matches the vial. You can request the CoA for the lot you will receive before you order. A useful CoA names the lot, the test method (usually HPLC for purity and mass spectrometry for identity), the result and the date.

## Ordering

we have operated since 2019, ship next-day across the UK, and take payment by Pay by Bank via Wallid. Research materials can't be returned, but anything faulty or damaged in transit is refunded or replaced.

## Research use only

MOTS-c is sold for in-vitro laboratory research. It is not a medicine, is not for human or animal use, and nothing here is advice on use.
