SS-31
Mitochondrial protection
Elamipretide — the mitochondrial bodyguard that binds cardiolipin.
Also sold as
Research chemical vendors can't legally label products with the real name, so SS-31 often appears under coded SKUs. If you're shopping and see any of these, it's the same compound:
- SS31
- Elamipretide
- MTP-131
Codes shown are for identification only.
Your draw
What it actually is
A four amino acid peptide that selectively binds cardiolipin in the inner mitochondrial membrane, stabilizing the electron transport chain and preventing the cytochrome c leak that drives apoptosis.
Why people use it
- Mitochondrial myopathies and primary mitochondrial disease
- Age related muscle weakness and 'sarcopenia'
- Heart failure with preserved ejection fraction (HFpEF)

Typical timeline
General pattern for the Mitochondrial category. Individual response varies.
- Week 1Energy floor lifts. Fewer afternoon crashes. Workouts feel less taxing.
- Weeks 2–4Endurance and recovery both improve. Some users report better glucose control.
- Weeks 4–8Peak effect. Consider a break so mitochondrial adaptation is preserved, not blunted.

The reconstitution math
- 1Reconstitute the 10 mg vial with 2 mL of bacteriostatic water. Tilt — don't shake.
- 2Concentration becomes 5,000 mcg/mL (5 mg/mL).
- 3For a 1 mg dose, draw 0.200 mL — that's 20 units on a 1 mL insulin syringe.
- 4One vial gives you approximately 10 doses.
Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
