hCG (human chorionic gonadotropin) is a hormone that signals the body to preserve lean muscle mass while supporting metabolic function. In clinical use, hCG helps regulate fat metabolism and can assist the body in maintaining muscle during calorie reduction, which may improve body composition and overall metabolic efficiency. It also influences hormone pathways that can support energy levels and appetite regulation when used under medical supervision. In short, hCG helps the body manage tissue balance and metabolism, especially during weight-focused protocols or hormonal optimization plans.

In males, hCG stimulates the testes to produce testosterone by mimicking luteinizing hormone (LH), a key signal in the body’s natural hormone production pathway. This helps support endogenous testosterone production, testicular function, and sperm production—especially in men experiencing suppression from aging, stress, or testosterone therapy. Clinically, hCG is often used to help maintain fertility, preserve testicular volume, and support energy, libido, and hormonal balance. Bottom line: hCG helps keep the male hormone system functioning rather than shutting it down.

Yes—hCG can boost testosterone, but it does so by stimulating your body’s own production rather than replacing it.

hCG mimics luteinizing hormone (LH), signaling the testes to produce testosterone naturally. This makes it especially useful for men with secondary hypogonadism or those on testosterone therapy who want to preserve testicular function and fertility. When used under medical supervision, hCG supports endogenous testosterone production, helps maintain testicular volume, and can improve energy and libido without shutting down the body’s natural hormone signaling.

No—hCG is not testosterone, and it works very differently. Testosterone therapy replaces the hormone directly, which can suppress the body’s natural production over time. hCG, on the other hand, signals the body to produce its own testosterone by stimulating the testes, helping maintain natural hormone signaling, fertility, and testicular function. In clinical practice, hCG is often used as a supportive or complementary therapy rather than a replacement.
