I have been taking Morphogens nootropic for several years in its various incarnations and I’ve always been pleased with it. As time has gone on, the formulas have been adjusted, for better or worse, but this current one is a bitter. Since I take Thermogen in the morning for my caffeine source, I add a bit of extra oomph to it with a half serving (2 caps) of Brain. It really does the trick and I’m dialed in for several hours in the morning after I take it. Personally, the half serve does the trick and helps it last a bit longer but the full dose does very well on its own (not stacked with anything else). The caps are pink so you don’t get them mixed up with anything else (a nice touch). Highly recommend this and several other morphogen products!
