Gnc creatine mono works well for me, but for some reason it gives me insomnia which no other product has ever done. I have taken torrent and anabolic od and slept fine on both. So sow I am in search of a well priced creaine that I could use for the next few years. I am going to try kre alkalyn sci fit. I also may try green magnitude if that doesn't work. Once I find the creatine for me I can just stick to protein, a multi, and creatine for several years. Any opinions? I don't mind bloating but I don't want to deal with sleeplessness. Plus gnc products are terrible in my experience.
