RPM? and stack advice

[Jaredmus]

I got a sample of rpm and loved it, but my question is, is this i supplement that is good to bulk with? The reason i ask is because it has lots of caffeine, and i was just wondering if that would burn to much fat.
Im trying to put together a stack based off some gnc gift cards i have.
Thinking of going with
Cell mass-loved in the past
Nitro core 24-ITs only 28 for 56 servings with my gold card
And then maybe something else just not sure what, already have multi, i was thinking either rpm m-stak or intra aid
not sure any advice would be very helpful

any advice?
