for real, at that age use fucking gh or peptides. its a tiny inject and will be the most cosmetic thing she can do.
nothing oral will come close. there is no magic pill.
a big bowl of stfu and gh is the smartest choice here.
i have a topical that will help, but seriously i think gh is your best bet, hair skin and nails will get better and she will loose weight. a very small amount like 2-3iu of decent gh is all you need, less if its pharma.
get some 1/3cc slin pins with 31g 3/8inch needle, its like not even pinning.
my mom uses these np.
various x's of mine have all squaked about injects and all been fine with these.
