Well, tried slin pre-workout again tonight, and I felt great. No issue's this time finishing my workout and damm, do I look "FULL" and still vascular. I go to a small "Snap Fitness" gym, not some major bodybuilding gym, and I caught a lot of people checking me out of the corners of their eyes. I'm sure they were thinking "gear". So I know I'm changing quickly. I've never been this lean, vascular, and full before. It's like my cells are just ready to "burst". It's crazy. Great feeling. I really believe it's the slin more so than anything else I'm doing.
