What Is SS-31 (Elamipretide) Research Peptide?

SS-31 belongs to the Szeto-Schiller family of cell-permeable, mitochondria-targeting tetrapeptides developed in the early 2000s. Its alternating aromatic and basic residues allow it to concentrate at the inner mitochondrial membrane, where it interacts with the phospholipid cardiolipin. This property has made SS-31 one of the most widely referenced compounds in published mitochondrial bioenergetics research. Explore our SS-31 research overview and mechanism of action review.

What Is the Regulatory History of SS-31 (Elamipretide)?

A pharmaceutical formulation of elamipretide received FDA accelerated approval in 2025 under the brand name Forzinity for a rare mitochondrial disease. SpartaLabs SS-31 is not that drug product. It is a research-grade reference material sold strictly for laboratory, analytical and in vitro use. Read the full SS-31 discovery and regulatory history.
