Pal-GHK effects

  • Stimulates fibroblast collagen synthesis (via GHK portion)
  • Increases glycosaminoglycan and proteoglycan production
  • Improves dermal thickness and elasticity
  • Reduces appearance of fine lines with topical use
  • Anti-inflammatory effects in skin

PTD-DBM effects

  • Blocks CXXC5-Dvl interaction in hair follicles
  • Restores Wnt/β-catenin signaling
  • Promotes anagen (growth) phase reactivation
  • Synergistic with valproic acid in preclinical models
  • Investigational topical hair-regrowth agent

Pal-GHK side effects

  • Topical: very low rate of irritation or sensitization
  • Occasional contact dermatitis
  • Not formulated or tested for injection

PTD-DBM side effects

  • Limited human safety data
  • Theoretical: off-target Wnt activation in non-follicle tissues
  • Possible scalp irritation with topical use
  • Long-term safety in chronic use unstudied

Pal-GHK dosing ranges

Topical anti-aging (cosmetic)

Pal-GHK vs PTD-DBM — common questions

What is the difference between Pal-GHK and PTD-DBM?

Pal-GHK: Lipophilic GHK derivative — collagen-stimulating tripeptide for topical anti-aging. Typical dose 2-5% topical concentration mcg. PTD-DBM: Wnt-activating peptide that blocks CXXC5 — investigational topical hair-regrowth agent. Typical dose Topical formulation-dependent mcg. Both fall under the Cosmetic category.

Can you stack Pal-GHK and PTD-DBM?

Stacking Pal-GHK with PTD-DBM is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.
