Description
SS-31 (Elamipretide)
SS-31, also known as Elamipretide, is a mitochondria-targeting tetrapeptide designed to penetrate and accumulate in the inner mitochondrial membrane. It selectively binds to cardiolipin, helping to optimize electron transport chain efficiency, reduce oxidative stress, and protect mitochondria from damage. SS-31 is widely researched for its potential in aging, cardiovascular disease, neurodegenerative conditions, and mitochondrial disorders.
Key Benefits
- Mitochondrial Protection: Stabilizes mitochondrial structure and reduces oxidative damage.
- Enhanced Energy Production: Improves ATP synthesis and overall mitochondrial function.
- Cardioprotection: Reduces ischemia/reperfusion injury and supports cardiac function.
- Neuroprotection: Protects neurons from oxidative stress and may support cognitive health.
- Anti-inflammatory Effects: Lowers pro-inflammatory cytokines and systemic inflammation.
- Improved Exercise Tolerance: Enhances skeletal muscle energetics and physical endurance.
Administration Options
- Subcutaneous (SQ) Injection: Most common and preferred method for systemic use.
- Intranasal: Occasionally explored for potential direct neurological benefits (limited data).
- Intramuscular (IM): Used in some protocols for localized effects or higher bioavailability.
Potential Side Effects
- Generally Well-Tolerated: Most reported side effects are mild.
- Common (Mild): Injection site reactions such as redness, itching, or discomfort.
- Less Common: Headache or dizziness.
- Note: Long-term safety data beyond several weeks is still limited.
Note: SS-31 (Elamipretide) is not FDA-approved and is used exclusively for research purposes.
Peptide Combinations
Peptides it pairs well with:
- MOTS-C (synergistic enhancement of mitochondrial metabolism and metabolic resilience)
- BPC-157 (complementary tissue repair and anti-inflammatory support)
- GHK-Cu (enhanced anti-aging and regenerative effects)
Recommended Protocol Note: Some researchers suggest optimizing mitochondrial health with SS-31 prior to introducing MOTS-C for potentially better metabolic outcomes.
Peptides/Drugs to Avoid Combining:
- High doses of peptides or compounds that strongly stimulate reactive oxygen species (ROS) or excessive inflammation, as they may counteract SS-31’s protective antioxidant effects.
