I have a hard time believing the tren isn't making things even worse, even at 100mg. It's going to ramp up your autonomics far more than anything else you're taking (AAS-wise, can't speak for the mechanism of action for Reta).
A tiny dose of Nebivolol knocks me on my ass and pulls my HR down like 10 BPM or more...I know there are varying drug responses, but if your HR is still that high, holy shit.
Did your HR climb this high only recently, as you dipped into the really hard part of the diet? Usually it would decrease while dropping bodyfat, even with some of the chems in play, but when stress really rises during the last legs, it can creep back up.
But 95 isn't exactly a "creep."
10mg Reta holy shit

Maybe I'm naive, but that sounds like one of those doses only recommended or attempted by people on the internet. I've yet to hear a known bodybuilder say they were taking more than like 1-2mg.
