okay my friend is looking for a new cycle hes been shooting test cyp at 400-500mgs in his previous cycles.. which he has done a bunch before mainly of test cyp... hes thinking of either doing a 15 week cycle of test cyp at 800mgs or sust at 500 mgs what do you think would be better for him... im guessin it would be the test cyp at 800mgs.... hes 22yr, 220, 9%bf and has cycled a bunch before not sure of the exact amount
