Anyone use this and have good results?
I've tried superpump250, no xplode, shotgun, and some others and never had a pump. I may try this because my friend said it work realyl well and it has been around a long while. Any input on this?

Fast twitch and any of the other Nitric Oxide products are all doing the same thing. Increasing vaso-dialation via L-arginine... What seperates them apart is all the additional ingredients/stimulants they are adding.

That being said I have used fast twitch, vaso-charge, and NO-expode. I always felt a bit better using the fast twitch.

FYI it is great to increase blood flow for a pump but you may want to give some thought to shuttling in some BCAA's as well while your training. Include ~5grms of BCCA's along with your fast-twitch.
