I just received a sample of Growth XT. I think sleep is going to be the biggest benefit I get out of it. I often wake up groggy and not feeling rested at all. Takes me a long, hot shower and a cup of coffee to remove the fog.
Gonna try it this weekend and if all goes well, on my ArA, Epi, ABE cycle in a few weeks. Probably one of the stronger cycles I've ran so with the restful sleep I should see some nice gains.
