As far as what is currently on the market, I've used Pump Juice Extreme almost exclusively since it was first released. I add some citrulline malate and it's perfect.

Controlled Labs released a new one, White Rapids, not too long ago and they sent me a tub. At 2 scoops, it's fantastic. Only thing I added to it was beta alanine. But everything else in there at 2 scoops is exactly what I want and the perfect doses. Flavor is solid, too.
