Are femara (letrozole) and norethindrone used for stage 4 endometriosis?

Not very successfull: No medical treatment has ever been shown to be effective in treating stage IV endo. This stage means that there is deeply invasive endo usually between the rectum and vagina or cervix. Endo nodules are by definition deeper than 5mm, and the hormones can't penetrate well and they don't respond.

Why bodybuilders use Clomid (clomiphene) with nolvadex for PCT?

Why bodybuilders use Clomid (clomiphene) with nolvadex for PCT?

Post "Cycle" Therapy: From what I have researched people seem to be of the belief that nolvadex is a superior anti-estrogen but clomid (clomiphene) is better at restoring testicular function so some people use both. I do not recommend any of these medications and believe old fashion exercise and natural body building without any supplemental medications is the most healthy approach! ...Read more
