Hey there, RBT and greetings from SoCal.
Just some "housekeeping" for our newer members.

Be careful not to post dosages, as this site has a strict policy against facilitating self-medication.
You list some strong medications here that need close medical supervision.
Tamoxifen was developed to treat breast cancer by shutting down estrogen receptor.
Letrozole is also a breast cancer medication, acting as an aromatase inhibitor.
Bio-identical hormones should act, in theory, the same as natural hormones, although there is a large body of literature which suggests some differences.
Experimentation with these substances is dangerous business.
Your 2-3 week, so-called "fat redistribution," is almost certainly "placebo effect." Fat does not actually redistribute. New fat cells are preferentially formed under the new hormonal regime in the body. It should take months to see hip and butt growth, even under high doses.
Breast buds can begin to form early, however. It is the result of the balance in your body between your testosterone levels and your estrogen levels. As is often said, "your mileage may vary."
