OK. This is a strange one. I've run several Osta cycles over the past year with absolutely no problems. On my last cycle, at the end of the last week, I started to get these weird chest pains. Heart was palpitating for about a day. BP was fine so I went to the doc and everything checked out fine. EKG, ultrasound, etc. was good. Since I was stacking some GW and some GHRP, I wasn't sure what caused it. So I ended the run and took a couple of weeks off.
Yesterday I took 15mg of Osta starting a new cycle and the exact thing happened again. I'm pretty sure it's nothing serious but it's pissing me off because I love Ostarine. After 2 or 3 days it goes away.
The only thing I can think of is that I had opened a new bottle at the end of the last cycle and was using that again so maybe it's a bad batch. It's hard to tell.
Anyway, just wanted to put that out there for anybody else who might have this now or in the future and to see if others had this same experience.
