Syn-Coll
Summary
SLU-PP-332 is a small molecule exercise mimetic that activates estrogen-related receptors ERRalpha and ERRdelta (ERRa/d), transcription factors that drive oxidative metabolism programs. In animal studies it significantly enhanced endurance capacity and metabolic fitness without exercise, mimicking many of the cardiovascular and metabolic adaptations of aerobic training.
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
  • Significant enhancement of aerobic endurance capacity
  • Increases mitochondrial density and oxidative metabolism in muscle
  • Promotes beneficial shift toward oxidative muscle fiber phenotype
  • Improves cardiac efficiency and cardiovascular fitness markers
  • Potential for obesity, metabolic syndrome, and heart failure treatment
  • Exercise mimetic for populations unable to exercise (disability, frailty, disease)
  • 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
Side Effects
  • Limited human data; all studies are preclinical (rodent)
  • Unknown cardiovascular effects with long-term or high-dose use in humans
  • Potential hormonal interactions via ERR pathway (ERRs modulate estrogen-related signaling)
  • Off-target effects not fully characterized
  • Generally well-tolerated
  • Rare mild irritation at high concentrations
  • Possible sensitivity in individuals with inflammatory skin conditions
