I want to start using the GHK-CU, but not really sure how to proceed. I’ve read all the posts and I think the best way is to go injection. I have been healthy and active all my life up until 2018, my mother became ill and that was the start of my decline. I cared for her until her death in late 2019. I am stiff and can hardly get around. I have inflammation and water retention. I can not stand for very long where as before I could work outside from early morning to late at night, then start over the next day. I need to know the large bottle of the GHK-CU, how do I use it for injection. I believe from what I have read that it will help me get my life back.
