I'm curious as to how long it takes for Primo to kick in, I started it w/ Dbol about a week ago and have had severe heart burn ever since. I'm considering laying off the Dbol and running just Primo, but I really like the almost immediate increase in strength from the Dbol and don't want to have to cut back on my workouts. By the way, yes I'm one of those new guys and kind of testing the water here which is why this is the gear I chose.
