Clinical studies & research

Our peptides are not just trendy ingredients—they are proven by science. Below are some of the most compelling peer-reviewed studies backing the effectiveness of our formulations:

GHK-Cu & Hair Growth (2023 Study in Bioactive Materials)

Showed a significant increase in hair regrowth via VEGF & Wnt/β-catenin pathways.
2% GHK-Cu resulted in faster, denser hair growth than control groups.

Matrixyl 3000 & Skin Rejuvenation (2019 Study in PMC)

Demonstrated a 15% increase in skin elasticity and reduction in wrinkle depth.
Found to be as effective as retinoic acid, but without irritation.

Acetyl Tetrapeptide-3 vs Minoxidil (2020 Study in Journal of Cosmetic Dermatology)

Increased anagen/telogen hair ratio, leading to thicker, healthier hair.
Outperformed 3% Minoxidil in comparative trials
