Pharmacokinetics of progesterone 800 mg/day vaginal progesterone (about 70 ng/mL and 12 ng/mL, respectively), although local progesterone levels in the uterus were 10 times higher with the vaginal route due to a uterine first-pass effect (around 1.5 ng/mL and almost 12 ng/mL, respectively). The duration of progesterone is extended by the intramuscular route due to a depot effect in which it is stored locally in adipose tissue, and can be administered once every 1 to 3 days. The half-life of intramuscular progesterone is significantly longer when it is injected into the gluteal muscles of the buttocks rather than the deltoid muscle of the
