Growth Hormone Peptides
CJC-1295
Summary
Syn-Ake is a synthetic tripeptide that mimics waglerin-1, a peptide found in the venom of the Temple viper (Tropidolaemus wagleri). It acts as a reversible antagonist of muscular nicotinic acetylcholine receptors, temporarily reducing facial muscle contraction and smoothing dynamic wrinkles. Often called a 'synthetic Botox' in cosmetic marketing.
CJC-1295 is a synthetic GHRH analog that stimulates the pituitary gland to produce and release growth hormone. The DAC (Drug Affinity Complex) version has a markedly extended half-life. The No DAC version (Modified GRF 1-29) preserves natural pulsatile GH release and is preferred in most protocols.

Key Benefits
  • Reduces depth of dynamic wrinkles and expression lines
  • Reversible muscle-relaxing effect on facial muscles
  • Smooths forehead lines, crow's feet, and frown lines
  • Non-invasive alternative to injectable neurotoxins
  • Rapid onset relative to collagen-stimulating peptides
  • Well-studied in in vitro and clinical cosmetic trials
  • Sustained increase in growth hormone levels
  • Enhanced muscle growth and strength
  • Improved fat metabolism and body composition
  • Better recovery and tissue repair
  • Increased bone density
  • Enhanced immune function
  • Improved skin quality and collagen production
  • Synergistic GH release when combined with GHRPs like Ipamorelin
Side Effects
  • Generally very well-tolerated topically
  • Rare skin sensitivity or contact dermatitis
  • Theoretical neuromuscular effects at systemic doses (not relevant topically)
  • Water retention / puffiness
  • Carpal tunnel syndrome (with prolonged use)
