Survodutide- Summary
- Pal-AHK is the palmitoylated form of the AHK-Cu copper tripeptide, created by attaching a palmitic acid chain to enhance skin penetration and lipid bilayer affinity. The palmitoyl modification significantly improves dermal bioavailability compared to unmodified AHK, making it particularly effective in anti-aging and hair growth formulations.
- 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.
