Alpha GPC

Have any of you tried Alpha GPC or Alpha-glycerophosphocholine? I've heard that it's a cognitive enhancer that helps with focus, learning, memory and that it also increases power in the gym. I ordered my first batch off Amazon and am going to start with a 600mg dose each morning. I've read reviews online where people have had great experiences, but also some others where people seem to have had headaches and depression. Anyway, I thought I would give it a try and was wondering if anyone in the Steem community had ever experimented with it. I will be documenting my reactions here too. I would love to hear about your experiences and/or advice. Thanks!
