Mechanism of ActionSS-31 concentrates 1000-fold in mitochondria, binding to cardiolipin on the inner membrane. It optimizes electron transport chain function, reduces reactive oxygen species, and prevents cardiolipin peroxidation during cellular stress.Humanin acts through multiple pathways including STAT3 signaling, binding to IGFBP-3, and activating the FPRL1 receptor. It protects neurons from apoptosis, improves insulin sensitivity, and has anti-inflammatory effects.

Research SummaryPhase 2/3 trials for Barth syndrome and heart failure. Studies show improved cardiac function, exercise capacity, and mitochondrial efficiency. Demonstrates benefits in ischemia-reperfusion injury models.Research shows protection against amyloid-beta toxicity in Alzheimer's models. Studies demonstrate improved insulin sensitivity, reduced atherosclerosis in animal models, and potential anti-aging effects. Human studies are limited.

Frequently Asked Questions: SS-31 vs Humanin

What is the difference between SS-31 and Humanin?

SS-31 is a anti-aging peptide that a mitochondria-targeted peptide that improves cellular energy production. being developed for heart failure and mitochondrial diseases. Humanin is a anti-aging peptide that a mitochondria-derived peptide discovered for its neuroprotective effects against alzheimer's-related toxicity. being studied for aging and metabolic benefits.
