The serving size is easy to handle and I've noticed my recovery after lifting feels noticeably quicker. It's been about three weeks and the blood flow boost during workouts is real, so I'm sticking with it.

I was skeptical about any pill claiming to boost blood flow, but after a few weeks the pump in my arms during lifts is undeniably fuller. It also seems to help with that post-workout soreness, which is a nice bonus.

My gym sessions have noticeably improved since I started taking these—there's a definite pump during workouts that I didn't get before. They're unflavored capsules, so no weird aftertaste to deal with, just straightforward results.
