Experimentation, it's hard to say what will work for you, but here are a few basics for you to consider:
5/2 or 6/1, as long as you attempt to limit or regain that sensitivity. Some BN members will take 1-2 months off, personal preference I guess, I wasn't sure genetic males benefited with the lack of ovaries, clearly that's not the case anymore. The amount of daily xenoestrogens (fake estrogens as its called) we are exposed too adds to estrogen dominance. There's two kinds of estrogen receptors ER-a (alpha) and ER-b (beta). Alpha proliferates cell growth, beta protects against cancers causing metabolites. We want normal growth, not malignant growth. Phytoestrogens have affinity for alpha or beta, you want a good ratio of herbs that target alpha while having a mix of beta type herbs for added protection.
Limiting or inhibiting DHT (and IMO) to 98% to 99% provides the best chance to gain breast (male and female). One Hrt med does that Dutasteride (targets type 1 & II 5 alpha reductse, finasteride is about 95%, but finasteride upregulates Total T, which is non active, and finasteride up regulates estradiol too. Reishi mushroom is a non-steroidal 5 ar inhibitor, its about 85% at inhibiting type I & II. Fatty acids like gamma linoleic acid also inhibits DHT, somewhere around 85%, saw palmetto is about 75%, but it also down regulates progesterone receptors , possbly from beta sisterol.
IMO, an oral (standard delivery) and sublingual delivery is a good approach for elimantiong DHT,.... DHT destroys breast growth gains, it is responsible for facial hair and hair (scalp) loss, DHT can't aromatize to estradiol, making it the strongest androgen.
Sorry it's late, signing off.

hopefully what I'm saying is making sense, I'm nodding off lol.
