A Peptide That Targets Mitochondria

SS-31 is also called Elamipretide. It's a small peptide, just four amino acids long. Labs use it to study mitochondria. The amino acids switch between two types, aromatic and basic. That switch helps it stick to mitochondrial membranes during tests.

Papers usually say SS-31 binds to cardiolipin. That's a fat molecule inside the mitochondria's inner membrane. All of this happens under controlled lab settings, nothing more.

Research use only. For labs and research, not for people or pets.

What Labs Study It For

Researchers look at SS-31 for:

How it interacts with mitochondrial membranes
Cardiolipin binding
Electron transport chains
ATP production, in cell studies
How cells deal with reactive oxygen species

A lot of this comes down to how cells make and use energy. Some labs test SS-31 next to PEG-MGF too, especially when looking at energy pathways. None of this is medical advice. It's all for research.

Regulatory Status

The FDA hasn't approved SS-31 for treating anything. It's sold only for lab work.

Legal and Safety Info

This isn't a supplement. It's a raw compound for research. Keep it away from kids. Not much long term data exists yet, so only trained lab people should handle it.

If you buy this, you agree to use it legally, for research only.
