Brand: Organon
Pregnyl® 5000 is the Organon brand of hCG, a hormone the placenta makes during pregnancy. The medicine itself is made from the urine of pregnant women and is standardized by a biological test. It acts like luteinizing hormone (LH), the signal the pituitary gland sends to the ovaries and testes. In women, it's used to trigger ovulation in anovulatory cycles. In boys, it's used for undescended testes. In men, it's used to replace missing LH signals when the pituitary is underactive, either from birth or after pituitary surgery. In strength-training circles, hCG is mainly discussed for keeping the testes active and preventing shrinkage. The steroidy.eu reference notes that it prompts the body to make more of its own testosterone, but it doesn't bring levels back to normal on its own.
Pregnyl® 5000 is hCG, a protein hormone made of an alpha and a beta subunit. The alpha subunit is nearly identical to the one in LH, FSH and TSH. The beta subunit is what makes hCG act like LH. It's supplied as a sterile dry powder with a solvent, and the two are mixed before use. Each ampoule contains 5000 IU. Because it's a protein, it can't be taken as a tablet and is given by injection.
It is an Organon brand of human chorionic gonadotropin, supplied as 5000 IU of powder with a solvent for injection.
No. It's a natural protein hormone, which means it doesn't build muscle directly. It acts like LH and tells the testes to make testosterone.
In women, it triggers ovulation. In boys, it's used for undescended testes. In men, it's used when low LH signals cause low testosterone and low sperm production.
It can. The testes make more testosterone, and some of it converts into estrogen. That's why gynecomastia is a recognized risk.
Yes. hCG is banned in male athletes by the World Anti-Doping Agency, and it can be detected in urine tests.
Pregnyl and other hCG products are approved by the FDA for ovulation induction, undescended testes and low testosterone caused by weak pituitary signals, under prescription. This specific 5000 IU Organon product is not an FDA-approved medicine.
No. hCG is a prescription medicine in most countries, and non-prescribed use is regulated.
