I've done test e cycles many times before. I just started a test/deca cycle last Saturday. I have noticed that within the first few days after my first shot, my sex drive has dropped down to nothing. I have never payed any attention to this in previous cycles. I know that that when this does kick in, my sex drive goes through the roof.
So why is it that test e seems to stop your natural test production right away, but it take s like 3/4 weeks to kick in and feel/see the benefits?
