After using it for 2 weeks , I’d to stop because my face dried up , became dull and deeper wrinkles .

This is not a 4% solution

I’ve been using this topical GHK-Cu for about two months now and have been happy with it so far. The formula absorbs pretty quickly, although it can leave a slight residue if you don’t rub it in well enough. It doesn’t feel greasy and layers well with the rest of my skincare routine. My skin has been looking smoother and more hydrated, and this has become one of the only products I use now, along with my SPF and vitamin C serum. I think I need to keep using it a little longer before judging the full results, but so far I've been very happy with it.

Very pleasing aroma of the fragrance free, Ghk-cu copper peptides. I’ve noticed a significant difference in the texture of my skin, and I really look forward to putting this on my face.

Reviewing: Neurogan+Health CHK-CU Copper Peptide serum I read a couple books on the newer peptides, including skin topical peptides like Matrixyl and GHK-CU, so decided to give them a try. I'm giving 5-stars, but I haven't used GHK-CU or any of them by themselves. I followed advice and mixed them with a "carrier", in my case I had Cosmesis Advanced Triple Peptide serum, so I mixed all three together in roughly equal parts. I doubt the brand matters but be sure to know the ingredients sufficient enough to be effective (peptides are smaller part ingredients). In my case I bought at Amazon 'Skin Perfection' Matrixyl 3000 (matrikin), 'Neurogan+Health' GHK-CU (copper peptide), and 'Cosmesis' Advanced Triple Peptide Serum. From the first application overnight -- I saw a very clear improvement in my skin the next morning. You have to cycle peptides, so I only use it every other week. My skin has never, ever looked so good (I'm in my 50s with naturally good skin, but with aging, I needed a makeover. After a couple weeks, I started micro-needling it in while still half most. That's when my waitin' was over, rocking results. It's been about two months, skin looks fab. P.S. keep peptide products in refrigerator upon delivery, otherwise, they lose their effectiveness. I'm posting this same review for Matrixyl3000 product. disclosures: I have no financial interest in any of these skin products or any peptide products; this review is strictly my personal experience that I thought others would want to know about. Do your own homework, this review is not medical advice of any kind nor am I a medical doctor.

I started using this product and was happy with it. The serum was dark blue and felt silky and creamy, just as a real legit GHK-Copper Peptide should be and I saw results. Fast forward on my 3rd purchase, opened the bottle and serum was thick grayish green gloo and sticky. I read that other buyers experienced the same thing with this producy. Did the company change? Who knows? Due to the seller's inconsistently, I will not order again.
