30 mg is a very high dose. When I take this much I have boners galore at the expense of a pounding headache, pronounced nasal congestion, and puffy face. I would reduce intake to 5-10 mg daily (you'll have to play with dosing of the liquid to find your sweet spot). You be plenty hard when needed (probably even more so) and this will give you the pump you want. Wear loose fitting shorts in the gym because you are likely to be hard much of the time whether you want to be or not.
