I think the impact of reta on HR is downplayed. In my sleep normally I'm in the 50s somewhere. On 3 mg reta I was low to mid 60s and now at 5 mg (first time at this dose, been on 3 mg for a while) I was low 70s last few nights.My RHR is 80 right now, up 12 points since I started the blast in late August. Was 68 in August.
The GH + Reta impacts it quite significantly. Obviously the additional AAS load too.
I'm hoping the HR will drop down as my body gets used to the new dose but we'll see.
