MOTS-c + SS-31

MOTS-c + SS-31 is a combination of two peptides, each with distinct roles in cellular function. It works by enhancing mitochondrial activity, with MOTS-c influencing metabolic pathways and SS-31 protecting mitochondrial membranes from oxidative stress. Early work on MOTS-c + SS-31 focused on their potential to improve cellular resilience under metabolic stress conditions. Research has also delved into their effects on muscle tissue and energy regulation. Today, it is primarily studied for its effects on:

• Mitochondrial function enhancement
• Cellular energy regulation
• Muscle tissue health
• Oxidative stress reduction

Beyond that, work continues on understanding their broader impacts on cellular health.
