HCG 5000 IU

HCG 5000 IU is Hilma Biocare's human chorionic gonadotropin, supplied as a single lyophilised vial. It binds the LH receptor and stimulates testicular function, making it a standard tool in fertility and hormone-recovery research.

What HCG Is

Human chorionic gonadotropin is a glycoprotein hormone produced by the placenta during pregnancy. It consists of two subunits, alpha and beta, and the beta subunit gives it specificity for the LH receptor. Because it mimics LH, HCG stimulates Leydig cells in the testes to produce testosterone and supports spermatogenesis. The 5000 IU vial is a high-strength presentation for extended research.

The History of HCG

HCG was discovered in the late 1920s by Aschheim and Zondek, who identified it in the urine of pregnant women as a marker of pregnancy. It was extracted and used clinically from the 1930s for fertility and cryptorchidism, and it became the basis of early pregnancy tests. Recombinant and purified urinary forms followed, and HCG remains a standard in reproductive medicine.

How It Works

HCG binds the LH receptor on Leydig cells and activates the same signalling pathway as luteinising hormone, stimulating cholesterol conversion to testosterone. In the testes it supports androgen production and, in combination with FSH, spermatogenesis. Because it acts directly on the gonads, it can maintain testicular function when pituitary LH output is suppressed. It is cleared by the liver and kidneys with a half-life of roughly a day.

What the Research Shows

• HCG has been studied extensively for fertility and hypogonadism.
• Trials examine its use alongside testosterone replacement to preserve testicular function.
• Its LH-receptor mechanism is well characterised.
• HCG remains a standard in ovulation induction and male fertility research.

Research Context

HCG has a long history in reproductive research. Beyond fertility, it has been studied as a marker of pregnancy, as a stimulant of testosterone production in hypogonadism, and as a way to preserve testicular function during testosterone therapy. One recurring finding is that prolonged HCG exposure can desensitise Leydig cells, which is why intermittent regimens are often used in research. The hormone's beta subunit is also the basis of many pregnancy tests, a practical application that dates back to the 1930s.

Strength, Pack and Authentication

Each vial contains 5000 IU of lyophilised HCG, sealed and packed in a printed carton stating the compound, strength and storage instructions. A scratch-off security code inside the box links the pack to Hilma Biocare's records. The powder is stable before reconstitution; the solution should be refrigerated and used within the recommended window.
