What SS-31 is
SS-31 is a Mitochondria-targeted tetrapeptide. A tetrapeptide that associates with cardiolipin on the inner mitochondrial membrane, studied for effects on electron transport efficiency and reactive oxygen species.

Where it sits
Incretin compounds are grouped by how many receptors they act at. A single agonist works at GLP-1 alone, a dual agonist adds GIP, and a triple agonist adds glucagon. The receptor count is the clearest way to tell one from another when the names are unfamiliar.
Other names
SS-31 is also written as Elamipretide and MTP-131. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
Others in the metabolic and GLP-1 range
SS-31 sits in the metabolic and GLP-1 group. The compounds below share that grouping, which is the useful starting point when comparing one against another: same group means the comparison is like for like, different group usually means it is not.
