What was your cycle and for how long have you had the puffy nipples?
I am going to assume that you didn't use an aromatase inhibitor during the cycle so estrogen is high hence the puffy nips and low libido.
Generally to resolve this you would take an AI to reduce estrogen levels and a SERM to treat/stop the gyno.
You are currently taking aromasin and nolvadex so this will hopefully resolve it.
I would stop using the HCG, as it is suppressive we don't want it during PCT it should be used during the cycle. Also at the doses you are using it can cause a lot of aromatisation.
Continue taking nolvadex at 20mg per day for another 5 weeks along with the aromasin. I am not sure how much aromasin you should use as I'm not familiar with its dosing.
