i have a question because i am subject to being drug tested....if the half life of deca is 6 days, how is it that it can still show up on a drug test a year later.....it seems like all of it would be out of your system by then....and on a side note, i have seen a few different pages that have different half lives of deca, they range from 6-15....does anybody know for sure what it is....thanks bros
