All right, me and my buddy have been injecting fina for about 2 weeks now. We each gained around 8 lbs, and strength has been increasing at a nice pace. Lately when I have been sticking the pin in it hurts, Is this scar tissue or what? Also 2 days ago both shoulders were way sore, and seemed to be red and swollen. It feels like a knot, but im worried that something crazy might be going on. Any comments would help.Help... Fina Freakin me out!!! undefinedundefined
