sustanon is supposed to be injected just once a week believe it or not. it has 4 esters. 2 short and 2 long.. it was designed for ONCE A WEEK. each ester picks up after the other. hard to understand if you do not get how half lives work which many guys don't grasp. most of sustanon are long esters. very little of it contains prop. would you inject something with a 3 week half life EOD? didn't think so. so why inject sustanon EOD? if you want EOD then go with prop
because it can be a painful injection though I will split it up and do twice a week.. either way will work.
also it should be run a minimum of 14 weeks. for this reason its great to stack with deca, EQ or primo since those should be run 14+ weeks as well.. if you want to run a short cycle stick with prop or you will be wasting the long ester of sustanon.. if you want a moderate length cycle say 10 weeks or 12 weeks then stick with cyp
