I'm referring to the dosage instructions on both products (BN packet says 10g, which equals 3 scoops) - going by their directions there are twice as many doses in the same sized tub of Jack3d, but Jack3d is twice the price (hence, same value). But you do make a good point about most people upping their dosage of Jack3d as their tolerance levels increase. I'm fairly sensitive to stimulants and 1 - 1.5 scoops of the Jack3d were sufficient for me.
But don't take my post as negative criticism of your product - the stuff works great for me and I will definitely be getting it again after a few sessions in the gym with it now. In fact last night I only used 2 scoops and hit a PB on squats that I am attributing to your product. I actually find that instead of a big whack of energy and focus that only lasts for around 20 minutes as I found with Jack3d, I get a much more linear-feeling energy and focus hit. And there is no big crash afterwards either with the BN product like there is with Jack3d.
