I'm an advocate of newbies starting with a simple regimen of just PM. That's what I did for the first three months of NBE based on comments the Flamesabers posted early in her NBE journey.
PM not only provides the needed estrogen for stimulating breast tissue growth, but also will drive down your total T level. You won't need an anti-androgen (AA) starting out. It took me awhile to understand how that works. It involves one of several feedback loops that your endocrine system uses to control the amounts of different hormones, proteins and enzyme in the blood.
Still interested? Okay, then here goes....testosterone is produce by the testes in response to the presence of another hormone called lutenizing hormone (LH). LH is produced by the pituitary gland in response to how much T is present in the body. When your T level drops, the pituitary outputs more LH which triggers the production of T in the testes.
Here's the interesting part....the pituitary gland can't distinguish between T and E. As long as the combination of T+E is high enough, no call for more T (i.e., LH) is sent to the testes. The estrogen that PM provides (miroestrol) looks enough like the human estrogen (estradiol) to the pituitary gland to also disrupt the feedback loop for T production by the testes. In other words, PM indirectly inhibits the production of testosterone.
When I had my total T tested after 3 months on just PM, it came back below the normal range for a male and only slightly higher than the normal range for a female. Yes, girls have T, too, but only about 1/10 that of males. I was almost at GG level for T using just PM!
So, the point is, you don't need to put together a complex program of different estrogenic and anti-androgen herbs to get a good start growing breasts. A simple daily dose of PM at about 2000 mg is all you need. Once breast tissue has formed (breast buds appear) and you learn your body's sensitivity to PM (how quickly your breasts grow), you may want to add an anti-androgen to further reduce your T/E ratio, and specifically to target DHT another form of testosterone that is responsible for masculinizing the appearance of your body.
I hope this has not been too much to absorb. It took me months to begin understanding the basics of the endocrine system, so don't fret if it all seems too complex. It is.
