My heart rate has been elevated for the last two days on ostarine 20mg only cycle and I’ve only been taking it for one week looks like I’m gonna have to stop taking it

I’ve been lifting 4 years with consistent diet and training and I like my physique but I’m severely lacking mass I want to start a cycle but I’m very concerned with hair loss as I’m very prone to it I started losing at 19 and stopped it in its tracks with dutasteride and I was planning on running ostarine with an Enclo base and ru58841 for hair protection can anyone help me out anyone with better ideas?
