I'm getting back into lifting, and I need a boost. I lifted somewhat regularly last year, and I was taking 1-AD. I was happy with my gains, but I injured my neck and back, which prevented me from lifting. Now I am ready to get back into it, but 1-AD is no longer available. Any suggestions on a replacement. I will probably get some creatine w/ ethyl ester, but Im looking for something that is proven to work. Any advice would be greatly appreciated.
