im on my first cycle but i just switched to prop and i couldnt walk for 3 days after i did a quad shot with it. id say that is a side effect. i almost had to call off of work today.
felt like utter crap the entire cycle no energy horrible mood joints would pop and creak I had micro tears in both my elbow tendons lol but I gained 20 lbs on it so I don't regret it just won't run it again
