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 key ingredients in 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.
- Study conducted in laboratory conditions with ingredient testing
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.
- Clinical measurements taken over 12-week study period
Acetyl Tetrapeptide-3 vs Minoxidil (2020 Study in Journal of Cosmetic Dermatology)
- Increased anagen/telogen hair ratio, leading to thicker, healthier-appearing hair.
- Outperformed 3% Minoxidil in comparative trials for hair density metrics.
- Controlled study measuring hair growth parameters
These studies examine ingredient efficacy in clinical conditions. Individual results with cosmetic products may vary.
Why Our Formulas Are Different
No Fillers, No Gimmicks – Every drop of PLU Laboratories' formulas is backed by science - no unnecessary ingredients, just research-informed concentrations.
Clinically-Informed Dosing – Unlike many brands that use trace amounts of peptides, we formulate at concentrations aligned with those used in published research.
