Well I have to say that say as of right now it lives up to its claims. I took it Friday afternoon 2 hours before a heavy bicep workout, by the end of my fourth exercise my arms actually hurt they were so pumped, no exaggeration. Still being skeptical of a 18-24 hour pump, i woke up the next morning with my arms still pretty hard, me and my training partner hit chest and triceps wide open the that morning, my chest hasn't felt that tight and full in months. I'll continue to let you know how the other doses go.
