I am currently taking 750mg a week of sust and I am on my second week of dbol at 40mg a day, I was training biceps today and towards the end my skin over the lower part of my bicep turned bright red and became itchy, it was red before it was itchy, I trained two other muscle groups after biceps and had no problems. Any ideas? Also should probably note, even though it might get me some crap, I took 25mg of Viagra last night, no problems in bed just makes for a hell of a night. Also, im 22.
