This is what I do for my training days using Yok3d and have gotten some really good pumps...but not with Yok3d alone...
4 caps Yok3d 2 hours prior to training (this is just to try it out, since I got it for good $)
2 1/2 scoops of LG Science Anadraulic State GT 1 hour before training
2 scoops of LG Science Anadraulic Pump (additional Arginine) 20 min prior to training
2 scoops Modern BCAA's w/1-2 scoops Jack3d mixed and sipped during training
Have had some pretty intense workouts with this supplement combo...may be overkill to some, but it is what works for me...especially since I mostly train at 5 a.m. That is the time when our testosterone is at its peak, and fat burning will be more dominant.
Hope this helps a bit! Good luck and hit it hard!!!
