I ran RUI liquid clen. I hardly felt the sides that everyone says are so extreme even at 140mg per day. The things that let me know its g2g though are I have trouble sleeping on it, Im always hot, and I sweat like a stuffed pig in the gym.
I have 1 female client and 1 male using AG clenbuterol right now with good success. I would recommend it, but don't run cycles with more than 60mcg/clen/day. Make sure to use clen cycle-aids like taurine/potassium and N2Guard.
Definitely ag-guys. There albuterol is good too; prob the best around. I used 15 mgs of GWP albuterol and felt nothing. 4 mgs of www.ag-guys.com is awesome though! Albuterol is way better... Trustme.
