However, if this effect exists at all, it must be very minor, due to the excellent gains that many have made, and from the fact that no one has noticed any such thing from Clomid, which has the same activity profile."
Its basically saying, yes, gains can be effected. How severe are they? Thats up to debate, though no one is gonna argue that you will gain reguardless if you are using Nolva on cycle or not.
IMO it is best to run an AI from the beginning of your cycle and keep estrogen under control from the beginning instead of trying to get it under control when sides already begin to show. Like the method people use when using Nolva on cycle.
On a side note, Nolva on cycle should NEVER be used when including a 19-Nor in your cycle. And Nolvadex will do nothing for any deca induced gyno so there would be no need for it.
Deca causes progesterone induced gyno, not estrogen gyno taking nolva will only worsen your chances of getting progesterone gyno because nolva is known to cause a greater uptake of progesterone at the receptor when u take it. So, if u want to have Deca dick and puffy, lactating nipples then go right ahead.
