Well since your profile says student, I'm guessing you're young. (younger than 23, or so) anyway.
I would keep the Spike, Power Drive, get a few tubs of Surge to last you, and since you want to add mass, alot of Grow!. Metabolic Drive for before bed shakes.
Drop the Carbolin 19, Cy Wilson has said it shouldnt be used concurrently with Spike. And in your situation, I think Spike would be more effective.
I've never tried Power Drive, but my guess is that Spike will be enough for you to help with your workouts. I would drop that and use the money towards Grow!.
The main thing is that suppliments are just that: suppliments. Nothing will help you add mass more than real food. And lots of it.
