Thanks for the information OP! I’ve been dealing with random heart-palpitations for almost a year now. I never had any pain, or shortness of breath, they just concerned me because it’s obviously irregular. I saw a doctor and he told me to monitor the supplements I’ve been taking, and to see him again if it gets worse. I’ve barely worked out, or taken any supps for the past four weeks. My palpitations almost stopped completely during this time.
My usual pre-workout was a caffeine pill, BCAAs, beta alanine, creatine and citrulline malate. However, yesterday I only took beta alanine and BCAAs before doing 5/3/1 deadlift day with BBB, and my heart was going crazy while I was resting a couple hours later. These were the first supps I’d taken in almost two weeks. I think it’s got to be the beta alanine, which I always assumed was pretty innocuous.
Long story short, I’m going to cut the beta alanine too and see how it goes!
