SS-31

Mitochondria-targeted tetrapeptide for cellular energy repair.

01 · Overview

What it actually is

SS-31 (elamipretide) is a rationally designed tetrapeptide built to do one thing: get into mitochondria and fix the membrane. It selectively binds cardiolipin — a fat unique to the inner mitochondrial membrane that degrades with age and disease — and stabilizes the machinery that produces ATP.

That makes it different from most 'energy' compounds. Caffeine borrows energy; NAD+ supplies raw material; SS-31 repairs the generator itself. It's been through human clinical trials for mitochondrial myopathy, heart failure, and age-related kidney decline, and it remains one of the more mechanistically credible longevity peptides in active research.

02 · Fit

Who this is for

People chasing the energy floor — those who feel their cellular battery draining faster than it should, especially alongside NAD+ protocols.

03 · Mechanism

How it works

SS-31 (elamipretide) is a mitochondria-targeted peptide that binds cardiolipin in the inner mitochondrial membrane, stabilizing the electron transport chain, improving ATP output, and reducing reactive oxygen species at the source.

Documented effects

  • Improved mitochondrial efficiency and ATP production
  • Reduced oxidative stress at the mitochondrial membrane
  • Support for muscle endurance and recovery
  • Investigated for age-related decline in heart, muscle, and kidney function

04 · Use cases

Common uses

  • ·Rebuilding baseline energy and exercise tolerance
  • ·Recovery support during heavy training or high-stress seasons
  • ·Pairing with NAD+ for a two-sided mitochondrial protocol
  • ·Longevity-focused protocols targeting cellular aging

05 · Protocols

Cycle guidance clinicians commonly outline

Reference protocols paraphrased from published research and common clinical practice. Individual response varies. Work with a qualified provider before running anything below.

General mitochondrial support

Protocol

1–2mg subcutaneous once daily

Duration

4–6 weeks on, 4 weeks off

Notes

Energy and endurance changes are usually reported in weeks 2–4.

Intensive block

Protocol

2mg subcutaneous twice daily

Duration

2–4 weeks

Notes

Reserved for shorter pushes; monitor for injection-site irritation with twice-daily dosing.

Baseline reconstitution

Reconstitute 10mg with 2ml BAC water for 5mg/ml.

06 · Combinations

Stacking notes

The natural partner is NAD+ — SS-31 repairs the mitochondrial membrane while NAD+ feeds the reactions inside it. MOTS-c is the other common addition for a full mitochondrial stack.

07 · Safety

Side effects & contraindications

Commonly reported effects

  • ·Injection-site redness or itching
  • ·Mild headache in the first days
  • ·Occasional lightheadedness

Talk to a doctor first

  • ·Pregnancy and breastfeeding
  • ·Active cancer treatment without oncologist oversight

08 · Trivia

Fun facts

  • 01One of the only peptides designed from scratch to target a single organelle.
  • 02It targets cardiolipin — a fat found almost nowhere in the body except mitochondria.
  • 03Has been through actual human clinical trials, which is rare for compounds in this library.
  • 04Originally developed under the name Bendavia.

09 · FAQ

Common questions

How is SS-31 different from NAD+?+

NAD+ is fuel — a raw material your cells burn. SS-31 is maintenance — it stabilizes the mitochondrial membrane so the engine runs efficiently. They address different failure points and pair well.

How soon do people feel it?+

It's not a stimulant — no instant lift. Most reported changes in energy and endurance show up in weeks 2–4 of daily use.

Is it the same as MOTS-c?+

No. MOTS-c is encoded by your own mitochondrial DNA and works on metabolic signaling. SS-31 is synthetic and works on membrane structure. Different mechanisms, complementary effects.
