Hi Teddy,
BO works on everyone at a different pace and works best when the body temperature is 98.7 F or higher, iodine can help maintain a higher temp.
I have been taking BO for 2 years now and breast growth was noticeable by tape measuring after 6 months, maybe 1/2 inch. Feminine curves are taking even longer, butt growth took about a year and curves are still progressing. I wish I had taken baseline hip measurements. Bust growth went from 48 to 52, band has been a steady 41 but since I have lost 30 lbs band is 40, bust unchanged.
Another thing that started after a year and persisted for about 9 months was hip and lower back discomfort, which I thought was me getting old but later learned it was more than likely pelvic tilt, that discomfort has pretty much subsided but still gets me some nights as my body continues to feminize.
The thing to remember, breast growth is a marathon and not a sprint. BO takes time for most of us, it takes girls years to go through puberty while their body starts to take shape so it will not be much different.
Personally I like BO and I am continuing on with it, letting it work at its own pace, besides, friends and family don't really notice a slow and gradual transformation.
You should start to notice, softer skin, better nails that grow faster and your body hair should be growing back slower and finer if you shave or epilate. I do both.
You can learn more about a BO program from some of Lotus's writings. Hope hearing about my experience helps you with what you might expect long term.
