The research I've done indicates the two major requirements for breast growth are estrogen (particularly estradiol) and growth hormone/igf-1. Increasing estrogen can (but not always) produce a short term (weeks to months) boost in growth hormone. This seems to be why younger trans-women get more dramatic results from HRT than older - they have higher levels of growth hormone. I've been looking at what body builders take for boosting their GH levels. In that regards, I've been taking 6g of L-arginine and 3g of MSM once daily. It's only been a week, so it's premature to say if that's having an effect. Otherwise, the only other thing I'm taking is finasteride. That's where this all started for me - trying to fill in the small bald spot on the top of my head. Growing small boobs was just a happy accident.
