Summary
Eloralintide is a long-acting amylin analog under development by OPKO Health. Amylin is co-secreted with insulin and regulates post-meal glucose by slowing gastric emptying, suppressing glucagon, and promoting satiety. Eloralintide is designed for once-weekly dosing, differentiating it from the short-acting pramlintide (Symlin). It is being studied for obesity and type 2 diabetes as a complement to GLP-1 based therapies.
Syn-Coll is a palmitoylated tripeptide (Palmitoyl Tripeptide-5) that mimics thrombospondin-1 to activate TGF-beta, the primary growth factor driving collagen synthesis in the dermis. It is one of the most mechanistically direct collagen-stimulating peptides in cosmetic formulations.

Key Benefits
  • Once-weekly dosing (vs multiple daily injections for pramlintide)
  • Appetite suppression via central amylin receptor activation
  • Reduction in post-meal glucagon secretion
  • Complementary mechanism to GLP-1 agonists for combination therapy
  • Slows gastric emptying for prolonged satiety
  • Potential additive weight loss when combined with GLP-1 agents
  • Directly activates TGF-beta for potent collagen synthesis stimulation
  • Increases dermal thickness and firmness
  • Reduces depth of wrinkles and fine lines
  • Improves skin elasticity
  • Clinically validated in collagen induction studies
  • Complementary to retinoids or vitamin C
