Yeah the sides can get bad if u don't know what ur doing. That's why I got on this forum cause I didn't know much about aas and wanted to know more from ppl using instead of a dr sitting behind a desk exsperimenting. I have shoulder problems with my right side. And to be honest it still has the pain, but its 10x stronger. My next cycle I'm gunna b using decca because its well known for lubing up ur joints. I figure if anything will help that will, I hope! If not I just b a big mo fo with an aching shoulder. Lol! Also I did get acne a little but not bad, a few spots here and ther. Don't do something ur not comfortable doing. You might post ur own thread and see if u get feedback on something to help build ur shoulder up weather it b from diff excercises, prohormones, or aas. Good luck and thanks for stopping by. I will b posting here soon cause I will b doing my pct. Grrr! Hope I don't loose any strength
