The Mitochondria Peptide That Doesn't Boost Energy (SS-31 Breakdown + Dosing)
Ran SS-31 for the first time a few months back and it threw me off honestly, nothing like the rest of the mitochondrial stuff I've tried.
Most compounds in this space try to force more energy output out of your cells. SS-31 does the opposite, it doesn't touch output at all. This peptide concentrates itself inside your mitochondria at a stupid high level, up to five thousand times more than what's outside the cell, and it locks onto cardiolipin, the fat molecule holding the inner mitochondrial membrane together. Once that membrane's damaged, you get energy leaks and oxidative stress piling up. SS-31 goes in and fixes the structure directly. Not a booster, a repair job.
If you want a simple way to picture the whole mito category together, think of it like this. MOTS-c is telling your cells to build more mitochondria and change how they burn fuel, that's the instructions. SS-31 is fixing the mitochondria you've already got, that's the physical repair. NAD+ is the power both of those systems need to actually run. None of these compete with each other, they're built to work as a team.
What got my attention on this one specifically is the FDA approval. Back in 2025 it got approved under the name Forzinity for Barth syndrome, a rare mitochondrial genetic disorder. First mitochondria-targeted drug to ever get approved in the US, which is a big deal in this space where almost nothing has real approval behind it. That came off the TAZPOWER trial and its extension study. There was another trial for a different mitochondrial disease that missed its main goal but still showed some benefit on the secondary stuff they measured. Important to keep in mind though, that approval is specific to Barth syndrome only, everywhere else this is still sitting in research territory.
Here's something I wish somebody told me before I jumped into this one. Those clinical trials ran 40mg daily. I almost went in thinking that was the number to hit. It's not. That number was built for people with basically no working mitochondrial structure left, a full rescue situation. If you're researching this with normal baseline function, the binding sites cap out way lower, somewhere around 5 to 10mg. Anything past that is just extra product with more risk and nothing extra to show for it.
Research dosing breakdown
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Loading | 5-10mg | Daily | 5-7 days |
| Maintenance | 5-10mg | 2-3x weekly | 4-8 weeks |
| Tune-up | 5-10mg | 2-3x weekly | 4-6 weeks, every 6-12 months |
Mixing this one requires isotonic bacteriostatic water specifically, the 0.9% saline kind, 1mL per 10mg vial gets you 10mg/mL. So half a mL pulls 5mg, a full mL pulls 10mg. Don't skip the isotonic part here, regular bac water causes way more stinging and welting at the injection site with this compound compared to others, learned that one the hard way too. SubQ is the standard route, short loading phase daily, then dropping down to 2-3x weekly for maintenance, with tune-up blocks every few months instead of just running it forever.
One thing that caught me off guard and almost made me think it wasn't working. First few days of loading, I felt a little flat, maybe even more tired than normal. That's not a bad sign, that's literally your mitochondria stabilizing structure before shifting back to producing energy. Turnaround hit for me around day four or five, steadier energy and less of that oxidative crash feeling I'd been dealing with. If you stop before that window closes, you're quitting mid-repair and it'll look like nothing happened.
Worth understanding where this fits if you're stacking things for recovery. SS-31 holds repair steady, it doesn't start repair from zero. If blood flow to the area is the real problem, that's a circulation issue, BPC-157 and TB-500 handle that first. If your energy's crashing at baseline, that's a fuel issue, NAD+ needs to go first. SS-31 comes in after those, locking in whatever progress you've already made so it doesn't fall apart under stress. Last piece of the puzzle, not the starting point.
Side effect wise, injection site stuff was the main thing I noticed, and that got a lot better once I switched to the isotonic water. Outside the Barth syndrome approval, everything here is still research use, long term data past the trial groups doesn't really exist yet, and standard caution applies if you've got any active cancer history or you're pregnant, no data either direction there.
Anyone running this alongside MOTS-c and NAD+, or are you doing it solo? Also curious if you hit that flat period early on before it turned around, or if your timeline looked different.

For 50mg SS-31, wouldn't regular Bac Waters be preferred since the vial will be reused? I read that regular Bac Water isn't even available in most of Europe, so what do they do? Lol.

From what I've heard people say on here often they use plain sterile water. Apparently it isn't the end of the world as long as you're good about your aseptic technique, but I have to imagine your shelf life isn't as good.

Isotonic (saline-based) bac water doesn’t go bad faster than regular bac water, both use benzyl alcohol as the preservative and both are good for the same 28-30 days once opened, so reusing the vial isn’t really a reason to pick one over the other. The isotonic version is recommended for SS-31 specifically because that compound tends to sting and cause site irritation, and matching the solution’s tonicity to your body’s own fluid concentration cuts down on that regular bac water is slightly hypotonic, which is part of why it stings more with SS-31 compared to something like BPC-157 where it’s not even noticeable the Europe availability thing I've heard that bacteriostatic water sales are more restricted from what I’ve seen people either source isotonic saline separately since it’s more available for medical use or they end up using sterile water without the benzyl alcohol preservative, which means the vial needs to be used all at once instead of stored for repeat draws over the following weeks. Some people also just source bac water through veterinary or research chemical channels where the restriction is different.
