not sure if mine are weak but because of my bad back and having to take pain meds everyday, they are I am sure in not the best of shape, Just went to my pain doctor and had to pee for him! My urine is dark yellow and foamy! Told me " I do not know what you are taking but STOP!" Said the foamyness is from eating more protein than I need (only 1.25g per # of BW) and the dark yellow especially when it is 90+ degrees out is NOT GOOD! He said if I go on like that too much longer y kikdneys will be in full failue! I am thinking that the 3 weeks of Drol I did will be it! I used the 50 I had and was going to switch to D-bol for 2-3 weeks but I do not think I am going to rish it! What good are having 19 or 20 inch arms and a 500# bench if I have to get Dialisys 3 X a week!
