GonadotropinUpdated

Short answer

Yes, in the broad sense: the Novarel label describes hCG as a polypeptide hormone made of an alpha and a beta subunit.[1]

The recombinant product's label gives the size: two linked subunits of 92 and 145 amino acid residues, with carbohydrate attached, so it is a glycoprotein.[2]

Its alpha subunit is shared with LH, FSH and TSH; the beta subunit is what differs by hormone.[1]

The Novarel product is extracted from human pregnancy urine.[1]
