After finding out that years of pre-workout usage has rekt my resting HR, i'm looking for stim-free options as training completely without pre-workout just isn't the same.
I've been looking at Primeval Labs Mega Pre and Scivation Quake 10.0 Caffeine Free and they both look solid, but what is YOUR experience with stim-free pre-workouts and which one is your favourite?
