I've been using Alphamine for around a month or so, only once in the morning, and have been very pleased with the results. I'd like to add a GDA to the mix as well. I've tried Glycobol, and wasn't thrilled with it. I've heard Recompadrol and SlinSane are pretty good, but would like opinions. Since I'm going to be using it with Alphamine, I don't want there to be too much overlap with the ingredients. Thoughts?
