jackd is cool,,, start out with one scoop for wk then 2 nxt wk then most 3.... know a few people that were giving positive feedback but they started 3 scoops of the bat and by 3rd week they said they didnt notice it anymore and stopped taking it.
i havent hit 3 yet because i noticed some effects,energy focus etc., at one scoop for couple weeks to start,,, so now im getting into 2.
superpump was ok, diff but decent. noticed more effects from jck3d
