Only other one I would consider is Albuterol. But dude she has no desire to gain muscle? At all? Whats the point?....
Muscle is what burns the calories really. There is no magic pill to just melt fat. At least not one that wont fuck you up good.
I wouldn't give my girl t3 at all. Not even if she was wanting to compete. You fuck your thyroid up your in serious trouble.
Clen. Good way to burn out your adrenals and cause some nice heart issues.
You dont even want to consider the other shit out there either. Especially if this chick isnt even doing the basic shit to loose weight.
And really? Moderation? How do you know what you are even taking? Cause its been reliable as a source? There is still no guarantee and no way to tell what your actually about to give to her. You realize how the stuff is made and where it comes from and all that right? Anyone can pay a few grand for some t3 powder and cap it. Doesn't mean its done right or that the powder is even remotely legit. Shit comes in batches too so a lot can go wrong there.
Just have the wrong approach dude.
