Never used Vitargo. If I recall, it was too expensive for me. I use Scivation EXTEND, NOW Foods CarboGain, and ON Creapure Monohydrate. Sometimes my energy drink ends up being an intra-workout. Either way it doesn't really matter. If I'm doin legs it winds up intra-workout but usually for other muscle groups I try to get it down in the first 5 minutes of my routine.
