COA per batch4 mechanisms. Repairs the power plant.
SS-31 (Elamipretide) is a tetrapeptide that concentrates in the inner mitochondrial membrane and binds cardiolipin. It doesn't stimulate: it stabilizes and repairs.
Binds cardiolipin
Concentrates in the inner mitochondrial membrane and associates with cardiolipin, the phospholipid that organizes the cristae.
More ATP
By stabilizing the cristae it improves the efficiency of the respiratory chain, associated with greater ATP production.
Less oxidative stress
Reduces electron leak and reactive-species generation, protecting the mitochondria from damage.
Repairs, doesn't stimulate
Unlike agonists, it doesn't force signaling: it restores the structure of the cell's "power plant."
Combine with.
SS-31 is the structural piece of the "mito-stack": structure (SS-31) + signaling (MOTS-c) + cofactor (NAD+). For energy and recovery, not weight loss.
SS-31 repairs the mitochondria; it is not a weight-loss agent. Don't expect weight loss on its own.
Technical description.
SS-31 (also known as Elamipretide) is a mitochondrial tetrapeptide that concentrates in the inner mitochondrial membrane and binds cardiolipin, the phospholipid that organizes the cristae where energy is produced. By stabilizing that structure, it is associated with more ATP and less oxidative stress: it repairs the cell's "power plant" rather than stimulating it.
SuperBio Labs SS-31 is supplied as lyophilized powder with verified HPLC ≥99% purity. Each lot ships with an independent Certificate of Analysis confirming identity by LC-MS, peptide content (98–102%), and endotoxin levels (<1.0 EU/mg).
It is one of the mitochondrial peptides with the strongest clinical evidence among the new group: it received FDA accelerated approval (Sept 2025) for Barth syndrome under the brand Forzinity, and was studied in Phase 2 for dry macular degeneration (AMD). For energy and anti-aging in healthy people, its use is a reasonable extrapolation from that data — not yet proven in that context. Its documented primary objectives are energy and longevity; secondary, recovery and muscle strength in myopathy (it is not anabolic). It has no support for weight, gut, skin, sleep, or libido.

When to use SS-31.
Cellular energy
Declining mitochondrial function · fatigue · documented primary objective.
Longevity
Mitochondrial protection against oxidative damage · biohacker protocol.
Recovery
High training-load phases · recovery support alongside BPC-157.
Performance
Muscular oxidative capacity · secondary objective (not anabolic).
Mito-stack
Structural piece alongside MOTS-c (signal) and NAD+ (cofactor), alternating.
Cardiac function
Clinical study line · tissue with high mitochondrial demand.
Honest side effects.
Benign in trials. In the research literature the profile is favorable:
Local reaction at the injection site (most common) · better tolerated than NAD+ because it doesn't cause flushing · no significant systemic effects reported in the available studies. Much of the evidence comes from clinical populations (Barth syndrome, dry AMD); use in healthy people for energy/anti-aging is a reasonable extrapolation, not yet proven.
