i'm currently taking 50mg of that shit 2 hours before weight training in addition to 50mg effedrine and let me tell you...
i've been lifting weights that i didn't even think were possible,
i lift at about 20% heavier and that shit makes you feel psycho!!
right when i'm burning and think the set is over, this aggression overwhelms me and i do an additional 2 or 3 reps that hurt so fuckin bad that i'm left sore (on the muscle that i worked) for 4 days after that!
now, i've been taking effedrine pre weight training for a long time now and never felt such a "boost".
i've been on for several weeks and so side effects at all!!!
but then again, i'm only taking 25-50mgs 2-3 times a week only on weight training days where i do either legs, or back.
one thing i'll warn though...
that shit makes you so so so fuckin aggresive it's disgusting.
on it, i'm always a second away from a fight.
if somebody accidently bumps you or looks at you funny you feel like really hurting them... no joke!!!
i'm still undecided about the long term use of it pre-workout in 25mg dosage, but i'll keep you posted.
