So I picked up these three at my local grocery store since they we're crazy cheap compared to what I see on Amazon.

I tried the C4 instead of my normal pre and didn't really feel shit, but it was like $10 and is clearly geared more as a more casual preworkout.

The other two I haven't used yet. Buddy of mine said I should use the pro BCAA inter-workout and use the other one with dinner like 5-6+ hours after I used the preworkout.

Only thing is, between all three they don't really list how much exactly of everything they each have, I found a little bit about the caffeine content of the two ON jars but not the C4.

Since these all three are pretty weak on their own it seems, is there any problem with stacking all three in a day like my boy told me? I don't go too crazy in the gym so I feel like I really shouldn't need it, but he said go for it would really be an ideal stack for me.
