I kinda think it's a myth also. Didn't get it...but I did get a hint of unresponsiveness down there. I could see how that could lead to some folks psyching themselves out.
Funny thing about "deca dick" being a myth... back in the '80s it was reversed. People used to say deca would give you a 24 hour erection and make you boink like the Energizer Bunny.
because deca is enough like testosterone to shut down your own test production so while you may be more "anabolic" certain other functions that govern our hormone system as males gets shut off and is not produced....with the absence of a distinct androgen
I don't know the spcificiities involved but I am somewhat sure thats what happens.
personal experience very limited....
so take that into consideration.
first cycle primo only at 300-200 a week for ten weeks..
12 pounds permament....but I did notice that motivation to go the gym did decline after week 5 or so
then second cycle
that was not completed but did give me enough of a taste to notice the difference was primo plus a little dbol thrown in.......
a totally different experince for the positive..all the way.
