In a controlled human trial, GHK-Cu applied to skin raised collagen in 70% of volunteers, beating vitamin C (50%) and retinoic acid (40%), and improved firmness and elasticity
Combined with the Precision Peptide Genetic Test, your clinician identifies your baseline GLP-1 receptor sensitivity and recommends a starting dose and titration schedule that reduces sulfur burps while maximizing weight loss efficacy
