I haven’t tried Plazma, but I’ve been doing a mix of MAG-10 and a cyclic dextrin supplement (the main carb source in Plazma) and I have to say training has improved noticeably. The pump is definitely better, but I’ve also been doing a lot more volume and feeling less fatigued. I’m sure Plazma has more goodies, but the cyclic dextrin and MAG-10 I’ve been using is cheaper.
I’ve been using Surge Workout Fuel mixed with PeptoPro. Works awesome. No GI issue’s what so ever and I recover a lot quicker.
