you may want to run hcgenerate with letro to help prevent shutdown... there is absolutely no need for nolva whatsoever... just run letro and hcgenerate and get everything fixed!
I know a secret that means u will never get gyno....sssssshhhh keep it to urself.....DONT TAKE STEROIDS stick to eggs milk an cheese hahahaha i should be a doctor
To say how long is impossible because everyone reacts different... running hcgenerate alongside will definitely help keep shutdown to a minimum and so I would definitely recommend that... you could run the unleashed/post cycle combo after to speed up recovery
I ran Letrozole for over 8 weeks....joints were very dry, but I was still able to get the boy going. But there was a few occasions I remember the wife saying he wasn't up to pair.
