I experienced severe elbow pain in both my elbows half way through my test cycle...I told my doctor he said I must have torn the tendons in my elbows while lifting heavy weights. Also when on cycle your muscles r growing hence putting stress on the tendons. He mentioned that collagen is greatly reduced when taking AAS which can cause an injury alot easier. I was out of the gym for over 2 months with really bad pain in both elbow and couldn’t even bend them with out extricating pain...I have learnt my lesson and will never run a cycle without a mild amount of deca! Wasted half a cycle and definitely not worth the pain and keeping me out of the gym for that long! I started taking fish oils (6000mg) a day and the pain hasn’t been back since so I guess its helping? Give glucosamine a try either Glucosamine Hydrochloride - 1500mg per day or Glucosamine Sulphate - 1500mg per day. These are clinical proven dosages which can help relieve pain.
