I'm 3 weeks into my tren/test cycle.
Half way through the third week my tren injections started leaving my legs almost crippled.
Up until mid way through the third week the injection came with very little pain, just dull. Can barely bend my knees now. I do each quad every 4 days. (every other injection)
Why the sudden increase in pain? Should I start shooting elsewhere?
Edit: Just to add, I have to other tren sides. Maybe a little increase in sweating in the gym but thats about it. I have seen huge improvements on it.
