also why would I want to avoid anti-androgens in particular, if I may ask?

Anti-androgens hamper the production and utilization of testosterone in your body. Testosterone helps to build up your muscle mass and physical capabilities. When you have less testosterone in your body, it's becomes more difficult to improve or maintain your physical strength. As men age and have lower amounts of testosterone, their physical capabilities also tend to decline.

The most obvious change of an anti-androgen (spearmint) I've experienced is a severe reduction in my libidio, which oftentimes occurs due to a decrease in testosterone levels.

The good news is it's certainly possible to achieve breast development with pm and no anti-androgen. However, when developing breasts, your breast buds are likely to be sore and tender for a while, so you'll have to be careful when you do heavy lifting and such.
