Our diet program utilizes a calorie deficit, further broken down into daily macronutrient goals
Ultrastructural analysis using high-resolution electron microscopy has identified approximately 20 nm as the biophysical optimum for efficient transfer (Csordas et al., 2006

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
Increased immunity and antioxidant defense
Melanotan 1 (afamelanotide) is MC1R-preferential : it is comparatively focused on the pigmentation receptor, which is precisely why its clinically observed effects center on skin darkening and photoprotection rather than on sexual function or appetite
CDER does not conduct its own testing
