I don't want to lower my T levels, nor impact my male performance. I'm very much in the camp of wanting boobs without the feminized body.
My stack includes:
Clomid 50mg, three times a week. (Clomid is an Estrogen receptor agonist when Estrogen levels are low.)
Dydrogesterone 10mg, once a week, usually after work on Friday. (DYD works almost exclusively on Progesterone receptors.)
Ketoconazole shampoo applied to the breasts during showers. (Ketoconazole is an androgen receptor antagonist, and seems to slow hair growth on areas where it is applied.)
MSM 3000mg, twice daily, with 500mg Vitamin C along with it for absorption. (It doesn't work for everyone, but some women have significant growth with it.)
MSM Cream with Peppermint Oil, Tea Tree Oil, Lavender, etc; applied to the nipples and areolas occasionally.
Fish Oil, 8 pills per day.
If I've been off Clomid for a few days I sometimes use a topical estrogen cream with boron pills.
Everyone's journey is different. My regime works for me.
