I've got these Sylvester Stallone branded pills, one is pre-workout intensity, the other is post-workout reloaded. The pre-workout says it's a "scientifically formulated blend of workout amplifiers and muscle growth stimulators." The post-workout says "scientifically formulated blend of creatine compounds, nitric oxcide enhancers and insulin potentiators." I can list all the ingredients if it helps. Currently all I've been using for supplements are protein shakes, no explode and a multi. Can I just add these pills to what I take on workout days? Are these pills good or shit?
