Whats the best to stack with sustagen 300. I was gonna stack winny but im gonna hold on to it until i start deiting down. I was told to either stack with tren or add some more propionate to it. If so how much of a dosage and how often should I take the propionate or tren. Im either gonna take 300 mg of sust. a week or should I go with 450mg a week broken into like a sun/wed or mon/thurs. doses. I'm 5'7 with about 180 with under 10%bf. Im on a clean diet written out by my nutritionist. Im in the gym 6 days a week( breaking back and legs into two days a piece). Looking to gain about 10-15 pounds before first amateur show in april 2009. Just wanting some opinions and advice. Thanks
