About each compound
About Progesterone
Bioidentical progesterone is FDA-approved for use in women and is a key component of female hormone replacement therapy, balancing estrogen's proliferative effects on the uterus and breast. It also has calming, sleep-promoting, and neuroprotective properties via its neurosteroid metabolite allopregnanolone. In optimization medicine it is used in both women and some men for hormonal balance and sleep improvement. Oral micronized progesterone (Prometrium) is the gold standard.
About Testosterone Cypionate
A synthetic ester of testosterone, testosterone cypionate is an intramuscularly or subcutaneously administered androgen that provides sustained release of the hormone over approximately one to two weeks. It binds to androgen receptors throughout the body, promoting protein synthesis, muscle development, bone density maintenance, and secondary sex characteristics. The compound is primarily used in the treatment of male hypogonadism and as a component of gender-affirming hormone therapy.
