Sorry it took me a couple days to see this. Yes, I have experienced this. But only when I take Anastrozole or Cialis. ALL of my muscles are always less full, achy, and injury prone when I take any amount of anything that lowers E2.
I attribute my only two injuries, since I started taking gear, to Anastrozole and Cialis. I tore a hamstring while on .25mg Anastrozole EOD. And I tore a rear delt while on 10mg Cialis ED. “Why do you just attribute the tears to those drugs?” I’m glad you asked. Because my muscles felt sore and ached all the time on them. It’s a difficult feeling to describe. During every rep of every set, I felt like if I made one wrong move, or forgot one mental cue, I was headed to snap city. And twice, I did.
Never injured on gear, without those two substances in my body. And I train hard. Really, really fucking hard.
You are probably noticing it in calf’s and hamstrings because that is where the majority of your workload is, from bicycling.
