Okay, I'm an avid lifter for almost two years now. After recent doctor visits I've found out it's possible I have a heart condition and it runs in my family. So, I was wondering what I can take that is safe for me with my problem. I assume pre-workout supps are out now, but I'll stick with protein. My problem is without a pre-workout supp I usually don't feel the pumps and have as good a lift. So what can I take to maybe help me pre workout or any help at all!!! Thanks guys.
