I've done 50mg ED and 100mg ED. Both ended up with sore joints towards the end. MSM helped a great deal, so would deca if you like that stuff. I think MOST importantly is to focus on warmups and stretching, and to use a properly periodized training cycle while on your AAS cycle, so your body will have time to get used to the new strength. Start by focusing on hypertrophy and gravitate towards maximal strength over the course of your AAS cycle
