Side-by-side comparison of key properties, dosing, and research.

SS-31 (Elamipretide)
GLP-1 / Weight Loss Agonists
Enclomiphene
Summary
SS-31 (Elamipretide) is a synthetic mitochondria-targeting tetrapeptide that concentrates in the inner mitochondrial membrane and protects cardiolipin from oxidative damage. It is one of the most promising mitochondrial longevity compounds, studied in clinical trials for heart failure, renal disease, and age-associated mitochondrial dysfunction.
Enclomiphene is the trans-isomer of clomiphene citrate, a selective estrogen receptor modulator (SERM) that stimulates endogenous testosterone production by blocking estrogen negative feedback on the hypothalamus and pituitary. Unlike TRT, it restores testosterone while preserving or increasing sperm production and testicular volume.

Key Benefits
  • Restores mitochondrial function and ATP production
  • Protects inner mitochondrial membrane cardiolipin
  • Reduces mitochondrial reactive oxygen species (ROS)
  • Improves exercise capacity and reduces fatigue
  • Cardioprotective — studied in heart failure trials
  • Renoprotective — reduces ischemic kidney injury
  • Anti-aging via mitochondrial preservation
  • Potential in neurodegenerative disease prevention
  • Restores testosterone to normal range without exogenous androgen administration
  • Preserves or increases sperm production and fertility
  • Maintains testicular volume (unlike TRT which causes testicular atrophy)
  • LH and FSH levels rise, indicating intact HPG axis function
  • Option for hypogonadal men desiring fertility
  • Oral administration (no injection required)
Side Effects
  • Injection site irritation
  • Nausea (rare)
  • Generally well-tolerated in clinical trials
  • Visual disturbances (rare but class-related SERM effect)
  • Mood changes or irritability
  • Hot flashes
  • Elevated estradiol in some users
