We were doing cardio pre workout and stopped for exaclty that. It took away from the work outs. Do it after now....... well sometime lol. Slacking lately.
I take 1000 mg's a day. I find I get sick less. Seems if there is a nasty cold going around in the winter if I do get it I recover in 1/4 of the time.
Until its rock solid its dangerous i'll keep using it.
I've done 10 days on 5 off then back on again. This was low dose, 250 a day. I dropped weight easily, just make sure you keep your diet in check. Only sides at that dose was sweating lots and felt hot all the time.
