Honestly I doubt you will loose that much on 600mg. That is still an on cycle number.

As for dealing with the loss of mass I went from over 200# and really big on my frame to 165#, thin and fit. I just changed my priorities. I can tell you I stayed here because at over 50 years old my heart is WAY healthier as is the rest of my body. I weigh how I feel everyday over how others see me.

Lets face it being Body building big is a personal thing but being BB big is really about how other people see you. It is like body modification or tattoos. it becomes part of your identity. We dress, act, and are certain ways to express this. Being a BB is the same.

example: My wife wanted a boob job. I asked her why as she was lovely the way she was. She said it is deeply personal. I said OK but why? Basically after we talked she admitted that deep down it was all about how she saw others ladies and wanted to be able to wear clothes like them and fill them out. So, how others perceived her. Not the same as someone fixing a deformity or such.
