Carnie, has your gf tried any of the non AS methods of fatloss? I mean, if it's mainly butt fat that's the prob, has she tried ECA, clen, Nolvadex or yohimbine first? Maybe a bit of heavier weight training instead of 'toning'? Is she off birth control pills? It sounds like she's determined to do the winny anyway, but since you're trying to do a full research on the topic, have you looked into alternatives that don't risk masculinization?
