Drop it. Unnecessary! You'll get plenty good pumps with Phera. I really don't think a pump helps out a workout much and fail to see the appeal of the Pre-WO supps beyond them tasting good.
I'll say it again: if you get pumped beyond what you get from steroids, it's TOO pumped and counter productive. I like a healthy pump but too much just destroys my range of motion. My last bicep exercises slow down because my arms can barely close past 90 degrees...
