So your dog is almost 200 lbs. It must be very protective of you. I've thought about getting a dog like that just for protection in case someone breaks in. @brandypup
I think that's a good body weight for sure to start. A lot of people think you have to be single digits to look good and you don't. 10% looks really good on a big frame. @balancenomad
It's very possible that you are a super good responder. @balancenomad However, it's also possible that you had growth hormone issues prior. So by going on it you're seeing some big results.
