First question, for someone trying to gain mass is caffeine a good choice as a performance booster? I read a lot of conflicting info so I'm wondering what everyone's experience is. Supposedly it constricts blood vessels, which makes me think I'm not getting as good of a pump as I could.
I know it's popular to help with weight LOSS, so I'm not sure if it's working against me in terms of protein synthesis and messing with my metabolism.
And just for overall health, what's your experience with long term caffeine use if any. I'm only 27, I don't want to end up 40 with issues.
Next is about citrulline. At one point I took citrulline with juice before a workout and no caffeine. Im wondering if the effects I felt were in my head. I know you can't tell me that, but if others felt similar effects it might be enough proof. With a few scoops I felt an awesome energy boost, but it felt different than caffeine. It's hard to exain. But if I'm really not benefiting from it I don't want to waste my money. It's been a while so just wanted some reviews.
Thanks in advance
