Protecting groups as well as terminal functionalization could be removed through transition metal complex catalysis

Its one of the most extensively studied regenerative peptides, with research demonstrating its ability to: Stimulate collagen I, III, and V production the structural proteins responsible for skin firmness, elasticity, and vascular integrity Increase elastin synthesis restoring the bounce and resilience that menopausal skin loses Activate glycosaminoglycan production the molecules that hold moisture in your skin (think: natural hyaluronic acid production) Promote hair follicle health supporting thickness and growth in menopausal women experiencing hair thinning Reduce inflammation and oxidative damage protecting cells from the accelerated aging that menopause drives Enhance wound healing supporting tissue repair throughout the body, from skin to gut lining At Refine by Tulsi, we use GHK-Cu both systemically (subcutaneous injection) for whole-body collagen support and topically for targeted skin quality improvement
Detox & Liver Function: Promotes detoxification and supports liver repair
Tretinoin also plays a role in the drainage and expulsion of excess sebum and acne-contributing bacteria
If your syringe is not U100, ignore the units display and use mL
Together, these peptides work synergistically to promote increased muscle growth, fat loss, improved recovery, and overall vitality
