GLP-1 / Weight Loss Agonists
Orforglipron
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.
Orforglipron is an oral, once-daily small-molecule GLP-1 receptor agonist developed by Eli Lilly. Unlike injectable GLP-1 peptides, it is a non-peptide compound absorbed orally without food restrictions, representing a major convenience advancement. Phase 2 trials showed up to 9.4% weight loss at 36 weeks, and Phase 3 trials (ATTAIN program) are ongoing for obesity and type 2 diabetes.

Key Benefits
  • Enhanced skin penetration vs. unmodified AHK-Cu
  • Stimulates dermal collagen and elastin production
  • Promotes hair follicle anagen phase
  • Antioxidant and wound healing activity
  • Firming and plumping effect on aging skin
  • Improved bioavailability via lipid bilayer incorporation
  • Oral pill — no injections required
  • Once-daily dosing without food restrictions (unlike oral semaglutide)
  • Up to 9.4% body weight reduction in Phase 2 at 36 weeks
  • Significant HbA1c reduction in type 2 diabetes trials
  • Small-molecule stability — no cold chain requirements
  • Broadens access for injection-averse patients
  • Potential class-defining convenience advantage over injectable GLP-1s
Side Effects
  • Generally well-tolerated
  • Mild irritation at high concentrations in sensitive skin
  • Possible comedogenicity at very high palmitate concentrations (formulation-dependent)
  • Nausea (most common, dose-dependent)
  • Vomiting
  • Diarrhea
  • Decreased appetite
