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 Enanthate
Testosterone enanthate is a long-acting esterified form of testosterone with a half-life of 4–5 days, making weekly or twice-weekly injections standard. It is FDA-approved for hypogonadism and is one of the most prescribed TRT formulations in the US. In optimization medicine it is used to restore and maintain testosterone to youthful physiologic levels. It requires injection but offers stable serum levels with proper dosing frequency.
