What would happen if a woman took testosterone hormone shots regularly?

Depends!: Typically, i don't recommend testosterone shots for women. Standard testosterone shots for men are much to concentrated for women. The much small amounts that women would require are very difficult to measure. I think that creams & gels (but not those branded for men) are better options. Regardless, if you take too much, you could have facial hair, acne, permanent lowering of voice & enlarged clit.
