Bones grow from the ends, they have "growth plates" where tissue is added, and the bone gradually gets longer. If taken during adolescence, growth hormone can boost
normal bone growth. In this way, children with dwarfism are sometimes able to approach normal height as adolescents growing into adults.
After adolescence the growth plates close off, and you're as big as you'll ever be.
Resistance training increases the density and thickness of bones, but this causes no effect you can see without an x-ray machine.
Excessive use of growth hormone can cause agromegaly, a disease (or syndrome) where the lips, eyebrows, hands and feet grow disproportionately large. This also happens with people with giantism, like Andre the Giant.
Testosterone will broaden the jaw in long-term users, as part of "masculinisation" - men tend to have broader jaws than women. That's why if you look at film of Olympic sprinters in the 1980s and 1990s, rather a lot of them wore braces on their teeth. Their jaws got bigger, making their teeth get all gappy.
So no, drugs won't help your pansy wrists
Just get in the gym and lift weights, then head to Sizzlers and eat until they throw you out. Once you have big chesticles, thighs like tree trunks and bum cheeks that could crack walnuts, nobody will notice your pansy wrists.
