About each compound
About HCG
Human chorionic gonadotropin (HCG) is an LH-mimicking hormone used in TRT to maintain testicular function, prevent atrophy, and preserve fertility during exogenous testosterone therapy. It is also used in male hypogonadism as a monotherapy to stimulate endogenous testosterone production. Compounded HCG remains available after FDA discontinued most branded injectable formulations. It is an essential component of fertility-preserving TRT protocols.
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.
