i ran the ams mass stack and it shut me down bad and killed my sex drive. i would try something like havoc or h-drol for your first cycle or run just 1ad or decavol solo. i did run the ams super mastervol and saw good results with that but it will also shut your body down. all the ams products seem to work well but stacking them the first time out is pretty serious business. if you run them get your pct in check. you'll need it.
