I used kynoselen for a little while. Since you have to site inject I did it in my delt, quad, bi, and calf. Well I was thinking about doing site injects with prop/fina. The only thing is that I had a problem with the delts with kyno. The prop is a bigger pin. I play baseball and my shoulder hurt so much in my throwing arm when I threw. Would it be wise to do the prop there or just stick in the glutes and quads. Any reason why my delt hurt so much, scar tissue?
