I would seriously put a lot of thought before taking a 19 Nor. The suppression from those is far greater from any of the others.
However, one big thing to know is all the varied stories on here.
Joe12 said epi+1andro gave him lethargy and no sex drive where as I was the complete opposite. He says that the Epi plus 19 Nor gave him great sex drive and libido, and once again I was the exact opposite.
Just driving home the fact that we can sit here and tell you all day about the possibilities, but no one will really know how it will affect you until you run it. So many variables including what your current test is at, free test, estrogen, prolactin, are you on any medications that are affecting dopamine, serotonin, norepinephrine, Etc
I ran trest which is a methylated 19nor and it shut me down hard. I literally felt it destroy my libido within 30 minutes of taking the first dose LOL
EDIT: Also, I should clarify, if you're going to run longer than 4 weeks and start getting into 8 or more....then you will really want to invest in a SERM. ESPECIALLY if you are going to do a 19-nor. You will need the SERM to restart your balls.
OTC PCT is not a popular opinion. In my experience, you can get away with it 1. if you do a short cycle and 2. it's not super strong methylated compounds and whatnot.
However, I'd always rather have it on hand than not, just in case.
