Matrixyl vs Pal-GHK — common questions

What is the difference between Matrixyl and Pal-GHK?

Matrixyl: Palmitoyl pentapeptide that signals fibroblasts to rebuild collagen and elastin. Typical dose 3-5% topical concentration mcg. Pal-GHK: Lipophilic GHK derivative — collagen-stimulating tripeptide for topical anti-aging. Typical dose 2-5% topical concentration mcg. Both fall under the Cosmetic category.

Can you stack Matrixyl and Pal-GHK?

Stacking Matrixyl with Pal-GHK 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.

Which is dosed more frequently, Matrixyl or Pal-GHK?

Matrixyl is typically dosed: Once or twice daily for Topical anti-aging (cosmetic). Pal-GHK is typically dosed: Once or twice daily for Topical anti-aging (cosmetic).

Are Matrixyl and Pal-GHK FDA approved?

Matrixyl: Cosmetic ingredient (not regulated as a drug). Pal-GHK: Cosmetic ingredient (not regulated as a drug).
