Human chorionic gonadotropin is a glycoprotein hormone of pregnancy, and in men it binds the same receptor as luteinising hormone. That resemblance is what puts hCG in fertility medicine and in the supportive corner of hormone practice rather than among the anabolics.
Maxtreme box it as Gona-Max: three vials of 5,000 IU each, 15,000 IU to the carton. The contents are a lyophilised powder, reconstituted with sterile or bacteriostatic water and then injected, since a peptide this size does not survive digestion. The multi-vial format is the practical difference between this listing and the single-vial gonadotropins near it.
