Test cured my heart palpitations

I'm 26 and I've had heart palpitations ever since I was a teenager. I used to think I had heart problems but had all the test done and they all came back good. I used to have heart palpitations alot sometimes for a week straight, but I started 500 test cycle in May and ran it for 16 weeks and my heart palpitations have almost completely stopped. I've back down to 250 test a week from 500 but still I think since whole time I've been on test I may have had 3 heart palpitations. I cant find anything about test stopping palpitations online but it worked for me for some reason
