Pain in muscles?

[testro]

I'm currently on 500mg/enanth a week and 300mg/primobolan week. I have noticed that my muscles are EXTERMELY tight, my chest and biceps in peticular. Whenever i extend my arm out or try to turn my torsoe in a manner that stretches my chest, i get a slight pain in my muscles as if i were overstretching them. I've never experienced this before but this is my frist time taking primo, anyone have any ideas?
