^^^ I read all of that but where does it prove that you need to run test with deca?
your post actually proved the opposite
in paragraph 5 you said that deca metabolizes into DHN, I was actually THE FIRST person to write about that about 8 years ago and my articles are published which have been copy/pasted since then by others with zero credit given (but that is besides the point). dan duchaine and none of those gurus EVER mentioned it before, I was the one who brought that to light and I have the evidence on my hard drive on my computer lol.
and how do we solve that issue? not by running test with it, but by actually running a DHT derivative. hence why deca should be ran with proviron the whole way. using test with deca does not solve the DHN issues, it may mask the side effects but there is zero evidence that it does nothing for DHN. of course adding test will give the cycle more of an androgenic kick, there is no denying that. but not everyone wants that. Rick and I are actually gonna talk about this on our next podcast in depth which should be published next week
that is why I said earlier that guys in the 70's knew what they were doing, they had no idea WHY IT WORKED, but it worked. nobody ran test with deca in the 70's or 80's.. that didn't start until the very late 80's when SERM's were discovered in the bodybuilding world. would i recommend guys run deca without test? absolutely i would! it is a very mild and safe cycle and nothing wrong with it
here is an article done which dives into it more written on EF by george spellwin
