You're better off served if you take some Nolvadex instead of Clomid if you think your puffiness is from gyno.
Also, in all my years of experience, I have found that most causes of puffy nipples in teenagers COULD be from bodyfat %. Like I said, COULD. We don't exactly know since we don't know your bodyfat percentage. Gyno and bodyfat go hand in hand after the puberty years.
