Hello Dylan. I want to use Lgd. I am a female age 31. Been doing profesional bodybuilding all my life. I recentley got a thyroid problem. I have been trying to fix it fot the past year now. I have been on steroids before I had a thyroid disorder. I am thinking of using only sarms and no longer steroids. Is it advisable to use sarms with a thyroid functioning at 80 percent. I want to pick up fast amounts of mass that I lost and lean out. Thank you.
