"HCG is a glycoprotein. It is a dimer of the same alpha subunit (of 89 amino acids) used by TSH, FSH, and LH) and a unique beta subunit (of 148 amino acids). HCG behaves much like FSH and LH with one crucial exception: it is NOT inhibited by a rising level of progesterone."

"Human chorionic gonadotropin (HCG), a polypeptide hormone produced by the human placenta, is composed of an alpha and a beta sub-unit. The alpha sub-unit is essentially identical to the alpha sub-units of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha sub-unit of human thyroid-stimulating hormone (TSH). The beta sub-units of these hormones differ in amino acid sequence."

"Molecular dimers are compounds containing two noncovalently associated molecular constituents: subunits A and B. Glycoproteins HCG, FSH, LH and TSH all share an identical subunit A."

"Human chorionic gonadotropin (hCG) is similar to LH; it contains equal amounts of LH and FSH."
Yeah, they all pretty much say the same thing.
