Guys i take the ECA stack on the days that i work because i hit the gym before i work. I work 4 days on and 4 days off. The stack still wakes me up, and i do still sweat in the pits. Im wondering if the effects taper off like in Clen. Ive been doing this on/off thing for 2 years. And have used ECA regularly for like 5. No change in bodyweight/fat.
