I have my doubts that his planned cycle could have any negative effect on his libido...matter of fact, I'd put money on that it wouldn't.
It's really on a personal basis.Deca supresses me hard and thus I'll always err on the side of caution when giving advice to others.500/200750/3001G/400DIV
True, as with all AAS the way in which it can affect you can vary greatly from one guy to the next. IMO, most guys will not have suppression issues with deca as long as test is in the cycle at a decent amount in comparison to the deca....but it can happen, that is true.
