I starting taking this stuff about 1 1/2 weeks ago,and i am getting cramps in my feet and hands alot.I know that low cortisol levels will cause this but i read that PS won't lower cortisol any lower than natural levels.I haven't been training for a few months now,i was just taking it because i'm not sleeping much.I thought it might be helpful.I won't name the company these tabs are from,but they claim to have 550mg in each tab,of pure PS.I've been taking 2 tabs before bed and 2 when i wake up in the morning.I know it's usually 100mg per tab,of PS,and the rest a PS complex,but they say that all 500mg is 100% PS.Does anyone have an answer for me? THANKS
