Survodutide
Summary
AHK-Cu is a copper tripeptide composed of alanine, histidine, and lysine chelated to copper. Distinct from GHK-Cu, AHK-Cu exhibits strong affinity for hair follicle receptors and demonstrates potent hair growth stimulation alongside wound healing and skin regeneration properties.
Survodutide is a once-weekly GLP-1/glucagon dual receptor agonist developed by Boehringer Ingelheim and Zealand Pharma. Phase 2 trials demonstrated up to 18.7% body weight reduction at 46 weeks, among the highest reported for a dual agonist. It is being studied for obesity and MASH (metabolic dysfunction-associated steatohepatitis), where the glucagon component drives hepatic fat clearance.

Key Benefits
  • Stimulates hair follicle growth and reduces shedding
  • Increases dermal papilla cell proliferation
  • Promotes wound healing and skin regeneration
  • Antioxidant protection via superoxide dismutase activation
  • Improves skin elasticity and firmness
  • Supports collagen and elastin production
  • Up to 18.7% body weight reduction at 46 weeks (Phase 2)
  • Strong MASH activity — Phase 3 SYNCHRONIZE-NASH trials ongoing
  • Reduces hepatic fat content via glucagon receptor-driven liver oxidation
  • Once-weekly subcutaneous injection
  • Greater weight loss potential than GLP-1 monotherapy
  • Improvements in liver fibrosis markers in early data
Side Effects
