would replace ALCAR and purcee, if you like altyr might want to still take a cap, since the amount in RED BLAST is lower. you can still take a cap of purecee post workout (if your one of those people- ie people that take 1-2 caps over reccomended dosing)
it can replace stims, though for "stim whores" reccomend bodyweight dosing + 1 thermorexin or CB. Its not reccomended that you stack ephedrine with it.
btw- that seems like a round about answer, but replace really depends on individual response. for one person it can be a replacement for others.. they want more or different.... but generally yes it would replace them...
