On test prop in my fith week and my back is killin me...lower back specifically. My buddy told me i should stop taking the prop cause maybe its has a filler that isnt working well. He said he never had any lower back pain with anything he took and if he did he would get off it. So i think im gonna stop the prop and take some novla and run it with some winni v. Have u guys ever heard of lower back pain with prop???? i mean it really doesnt fell good
