I tried Levitra 20 mg pharma grade pre workout, it does give u better pumps but since my insurance stopped covering it and they only give me 6 pills per month I'm not using it no more pre workout.
and for the best pump .. 50-100mg of Viagra plus a double dose of the strongest Vitamin B complex and a high Arginine preworkout supplement. Your hands should turn and nice shade of purple before you get to the gym...
I have heard of this and it seems to be the latest fad with pre workout. I'm not really interested in trying it though. Like states before not sure how safe it is. I'm an old school guy and don't really do much pre workout stuff besides TNE and coffee. If your carbs are right the pump is going to be there plus the AAS you may be taking to help as well. This is just me though. I think there is a pre workout you can snort. No thanks.
