How RADIANCE Blend works, and what the research shows.
GHK-Cu stimulates collagen, elastin and skin remodeling and supports hair follicles.
Tesamorelin copies the brain's growth-hormone-releasing signal so the pituitary gland releases more growth hormone overnight, which is studied for skin thickness and belly fat.
No clinical trial has studied this exact combination.
The evidence is for each peptide on its own, and your physician weighs that when deciding whether the blend fits you.
