I don't know what you are taking, but to be 100% honest, the picture of me with 22inch were accomplished with 10iu ed of HGH, it really seamed that large dosages of HGH did help with arm size tremendously.
When that pic was taken 750 test 200 deca (for joints) and 200 mast.
I wouldnt bother with more than igf as a non competitor. If anything i should cut it to 500 test again but i fucking love mast and off deca my joints went even shittier. My sister (doesnt lift bro) has arthritis in knees, only 37, and was told she cannot play tennis again and is too young for a hip replacement (we both have shallow hip sockets on one side).
I have had to curtail squats and other lifts and activities that i felt were hurting me, much as i enjoyed them. I am learning (we all have that impulse to push it beyond healthy/failure) to curb my training etc. Last 2 times i was on physio table was for extensive damage caused by concentric movements ie leg pressing too hard.
