Any workout junkies out there? - Supplement ???

Hey y'all. Do I have any fellow exercise junkies out there?

I have congenital heart disease, bicuspid aortic valve disease with an aortic aneurysm. My aortic valve was replaced 5 years ago (bio-prosthetic) but the aneurysm was not repaired at that time due to endocarditis (it's only 3.9).

So my question... anyone using pre and post workout supplementation? I go pretty hard 6 days a week, strength and metabolic conditioning. To maximize my workouts and to aid recovery, I've started adding supplements. Nitric Oxide and BCAA powders pre-workout and Amino replete post-workout. There is NO caffeine in my nitric oxide powder.

Anyone have experience taking these with a heart condition? i'm going to ask my cardiologist of course, but was interested in patient experience as well. Thanks!
