Yes, I know it is a doctor visit sort of thing, I wanted to cover this possibility first. Maybe it is inconsistent in its overall effects on people. One thing I will note is that I had palpitations on Sunday, when last I had taken a preworkout on Friday, but was still using Beta alanine every day. I started having this issue in correlation to upping my beta alanine intake.
I will wait for more responses before I decide what to do.
