Compounded pellets are not. One testosterone pellet product is approved for men in the United States, but the compounded estrogen and testosterone pellets marketed to women for menopause are not FDA-approved and have not been through that review.
The core problem
Las Vegas treatment options: you cannot take it back out
Reversibility is the whole argument, and it is why we do not implant pellets in Las Vegas: a patch can be removed, an implant cannot. Every other form of hormone therapy can be stopped today. A patch comes off, a tablet is not swallowed, a cream is not applied. If a dose does not suit you, the exposure ends within days.
A pellet keeps releasing for three to six months. If the dose is too high, or you react badly, the options are to wait it out or to attempt surgical removal from a site where the implant has begun to be absorbed.
Pellets also tend to deliver supraphysiological levels, particularly of testosterone, well above the normal female range. That is where the side effects that do not fully reverse, including voice change and increased facial hair, become a real risk. More on that in treatment options, non hormonal options and side effects for the rest of it. A voice that has deepened does not come back when the pellet wears off, and that asymmetry is why Las Vegas patients are offered adjustable forms instead.
