Here's why GHK-CU it useless for you, please stop wasting your money on this 
What is GHK-CU?
GHK-Cu is a naturally occurring copper-binding tripeptide, you already have it in your body, its in your plasma, saliva, and urine. Recently people have been exogenously administering this tripeptide for its "anti-ageing properties". It achieves this by stimulating collagen production through modulating gene expression in fibroblasts. It balances the enzymes that break down old collagen and their inhibitors, which results in a significant gain in collagen.

Why It's Useless For You
All of this sounds great right? Shouldn't everyone take this? Well, no. For almost everyone reading this thread, the visible benefits are negligible because teenagers already have optimal collagen production and tissue repair. Your GHK-CU only starts diminishing around the age of 25, which means that up until then, the effect of exogenous GHK-CU is literally all placebo and cope. Adding more doesn't boost collagen beyond a healthy baseline, if you're a teenager or a young adult, your fibroblasts are already producing collagen rapidly for growth and development. This will mean that it will have virtually no visible benefits for you.
What to use Instead
The following things are stuff that have been shown to fix acne and lead to better skin unlike GHK-Cu.
-Tretinoin
-Isotretinoin (Accutane)
-Salicylic Acid
-Benzoyl Peroxide
if you have any questions leave them below and I'll try to answer you.
