adding on more chemicals while you are still in potentially a bad state isnt a very good plan. Especially lgd. and you need gw to go along with that as well.
I would strongly advise you follow Dylans PCT protocol for 4 weeks, wait 3, get bloods, and then see where you are at.
Plus, shit can that DR, he's clueless. Personally from what you've said, I wouldnt trust him with my dog.
