There are some products that have both estrogen and progestin (the active ingredients of testosterone) but they can be hard to differentiate.
The following products are for oral and vaginal use.
The top product for oral use is called Progestin, an organic, low-molecular-weight (low-melamine) progesterone hormone, sold under the brand names DHEA or LPAH. (Progestin is also known as drospirenone.) Progestin is a very effective oral contraceptive that can be used for at least 8 weeks, but is not effective for longer than 2 weeks. Progestin can be used as an estrogen in combination with a progestin to give birth to a baby. (This is the same reason that estrogen is not considered a "birth control pill" because it can also be used as a progestin. (If you are concerned about progestin side effects and how they may affect you, see our post on progestin and heart disease.) Progestin is the most popular progestin drug in the world. It has been used as a drug for the treatment of several diseases, including prostate cancer, uterine fibroids, and polycystic ovary syndrome. It is also available in liquid and powder form. Progestin is an oral contraceptive. It works by preventing ovulation (hormonal release of eggs) in women by blocking an enzyme called 15-hydroxyprogesterone. It is the only medication approved by the FDA for preventing pregnancy.
