the truth of the matter is guys in the old days 80's and early 90's would run deca alone with proviron for the simple reason is AI's did not exist in those times so they knew better than to stack testosterone. you can listen to our podcast with Nelson Montana where he talks about that. nobody in those days was dumb enough to use testosterone like people do today because they didn't want bitch tits, they would laugh at people who did that.
talk to any guy in their 50's in your gym and ask him about deca and he will have a 100% different opinion of the compound then if you ask a 20 something.
having said all that with the availability of AI's today stacking an androgen with deca is a smart idea
I recommend a low dose of either tren or testosterone with deca to give it an androgenic kick
you also need to use proviron when you use deca because nandrolones BIND to DHT receptors. THAT is why you get deca dick.
again it is interesting that guys in the 80's actually knew how to stack steroids better than guys today. they knew in that time to use proviron with deca. JP who is in his 60's always uses proviron in his cycles because he knows this info and it is nothing new.
today it is a joke the way guys stack steroids, they just stack 8 compounds with zero understanding of what they are doing
that is why i wrote a stacking steroids article that actually teaches you that you don't need to stack a million things, you can stack smartly and get the most out of your cycle
