... in the mountains where I was having too much fun and forgot to refuel
This stuff has really saved me on a few occasions out in the mountains where I was having too much fun and forgot to refuel.  It pushed me away from the wall faster than anything else I've tried.<br /><br />Pros:<br />1. It works fast, faster than the GU Roctane that I will also use from time to time.  In fact, after taking this stuff in, I can literally feel the surge of relief and boosted endurance in my muscles within ~10-15 minutes.  Nothing else I've tried gives me such a noticeable boost.<br />2.  The unflavored version doesn't have any flavor (or rather it has a neutral bland flavor).  It is what it is.. that's a big pro for me.<br />3.  Using a blender, I can make a calorie dense liquid that will last for hours and hours.  I like to do (3) scoops in 20 ounces with 80 calories of electrolytes for 500 calories.<br />4.  It's relatively cheap.  As of this posting, this stuff is 111 calories per dollar.  But you'll need to mix in your own BCAA'a and electrolytes to make it a more complete intra fuel. That could get expensive.  By comparison, GU Roctane is 50 calories per dollar so it's more than twice as expensive (for the variety pack), but it has electrolytes, BCAA's and OKG to make it a more complete fuel.  Maybe blend (2) scoops Vitargo and (2) GU Roctane together to make a 500 calorie super fuel?<br /><br />Cons:<br />1. It doesn't mix that well on the go.  Drinking a clumpy energy drink is distracting and I don't like it.<br /><br />2. The high absorption rate causes brief stomach distress directly after ingesting. I've almost upchucked this stuff a few times, I had to slow down and walk a few minutes until the nausea passed.  I think I can experiment with taking smaller sips more often to fix this, but for now I am calling it a con.
