SS-31 (Elamipretide) is a mitochondria-targeting tetrapeptide developed to support mitochondrial membrane stability and bioenergetic function in research settings. It belongs to a class of cell-penetrating peptides designed to localize within the inner mitochondrial membrane. SS-31 has been studied primarily in domains such as mitochondrial dysfunction, aging biology, cardiometabolic research, and neuromuscular models. In experimental systems, it has been observed to influence ATP production and reactive oxygen species balance.
Our formulation is provided in a stabilized pre-mixed injection pen for SubQ administration. Subcutaneous delivery supports consistent systemic exposure and high mitochondrial bioavailability in research protocols. Each unit is freshly prepared to preserve peptide integrity and ensure standardized dosing. This format eliminates multi-step vial preparation and supports simplified laboratory handling. The product is formulated strictly for research use only.
In research models, SS-31 has been observed to bind cardiolipin, a phospholipid unique to the inner mitochondrial membrane. This interaction appears to stabilize electron transport chain function → ↑ ATP synthesis efficiency and ↓ oxidative stress markers. Preclinical data show improved mitochondrial respiration and reduced mitochondrial swelling under stress conditions. Early human studies have explored its effects in mitochondrial-related dysfunction models.

Mechanism of Action
SS-31 works by targeting and stabilizing mitochondria, the energy-producing structures inside cells. In research models, it selectively binds to cardiolipin in the inner mitochondrial membrane. This stabilizes electron transport chain complexes → ↑ ATP production efficiency. Studies indicate ↓ mitochondrial reactive oxygen species (ROS) generation under stress conditions. These effects support improved cellular energy dynamics in experimental systems.
