I'm want to try out a different pre workout. I had been usingfor a while but have mixed opinions about it. It's not a knock against Iforce as I have their new product and have enjoyed the Acaia for focus + energy.. I just don't think I respond well to the GMS...I used Noxi-pro and from CTD labs in the past w/ some success. I know they removed the 1,3 from their old formula... I remember getting some pretty solid pumps from that..Off the top of my head, Citrulline, , and maybe are the main ingredients I'm lookin for. Not necessarily stim free. I'm looking for legit recommendations, not just reps plugging their own products..Thanks in advance.
