A lot of pro BBs have ruinind their natural Thyroid function. I do 40mcgs a day with strict dieting and cardio. It works.

Problem with a lot of women (not all), they want to take some miracle drug that will do it for them. They want the short cut to the benefit. I don't know why it's this way but it seems that way in America. T3 is a DRUG you use along with a clean diet and regular cardio. The results can be amazing. Also doing T3 with no AAS is asking for trouble. T3 will burn everything in it's way including precious muscle tissue. Muscle tissue is what controls our metabolism. Once she discontinues and she has less lbm, she'll get fatter than she was before T3. Your body will acclimate to anything you've done to it after the drug leaves the body.

I think taking 200mcgs once isn't going to hurt her. She should only do 40-60mcgs max. I read some BBs only do 25mcgs/day. Does she work out and eat a proper diet?
