I thought a beauty peptide would be harder to measure the effects, but Im excited to report noticeable change within the first 2 weeks. Sometimes change happens at a slower pace based on our 12 weeks in, and my skin has NEVER looked better! GHK peptides are doing their thing. Alright, I need to give you an updateit's been 12 weeks since I started using GHK The Peptide Craze: What Your Doctor Wants You to Know My Sunday facial before and after..After 18 KLOW injections. I can't get enough of the science behind this!! The peptides I use test at 99% purity. That is as high as a Peptide Therapy for Anti Aging, Immunity & Wellness Miami Stem Cell KLOW Peptide Blend: Advanced Healing & Regeneration Revolution Health & Wellness
