I did my first stanol injection yesterday into my quad, and i pushed and pushed but couldn't get anything to come out! Even after I took it out and put back in it wouldn't come out, and then I realized it must be clogged somehow when i couldn't even draw in air when the needle was outside my body. I switched needles, spilled about a third of the winny, and hit the delt, smooth as can be. Did I do something wrong here? This is second cycle and I thought I knew how to inject by now! Also, do I need to shake the TT stanol v? It looks a little milky on the bottom.
