Nolva/OTC Cycle questions. Possible Gyno

[mcq]

I have a question and was wondering if you could help. I have recurring issues with gyno. I took a couple of cycles of OTC Ph in the past and probably did it incorrectly. I am taking Halotest 25 right now (4weeks) then I am going to do 4 weeks of Epitest all by Powerlab Nutrition. I ordered the stack that comes with PCT, NOESTROGEN, and Liver support. The first 2 weeks on Halotest 25 were going good. I started the NOESTRGEN and planned to ride it out until the end of the 4 weeks of Epitest. During certain pars of the day my chest looks fine and nips are fine and then other parts of the day my nips are puffy and it appears that I have gyno. I need help. Don't know if I should just keep doing what I am doing or go with nolva, letro or both. And if I do, How do I dose and shoild i wait till after cycle or do it on cycle and should I keep taking the NOESTROGEN.
