Big increase in RHR · Castore: Built to Adapt

Big increase in RHR

June - August 2024 I was living in Portugal, lovely sun in the morning. Morning steps, cold plunge and sauna everyday. Super cool room on a night. I was on TRT and GH and RHR got down to about 48bpm.

This year June 2025 I started reta, still on gh, trt......and I only went up to 3mg a week. My RHR has gone up to almost 70. Even when I stopped in for 4 weeks it didn't really move lower.

Now I'm not sure why it's staying spiked, I was considering adding in a low dose Nebivolol but I know I shouldn't need to take something just to counteract that.

We all know RETA increases RHR in a lot. But what else can I look at to see if anything else is causing this?

Thanks
