Pregnant Mare Serum Gonadotropin (PMSG), also known as equine chorionic gonadotropin (eCG), is a naturally derived gonadotropic hormone obtained from pregnant mare serum. Supplied as a lyophilized powder, this veterinary hormone API exhibits both FSH- and LH-like biological activity and is widely used in injectable fertility products for livestock reproduction.

Our PMSG API is manufactured and supplied for veterinary pharmaceutical companies and distributors that require consistent bioactivity, reliable batch-to-batch performance, and full traceability from source material to finished supply.

Specifications & Supply Details

Features & Practical Applications

PMSG API is particularly suited for veterinary reproductive programs requiring reliable gonadotropic stimulation, including:

▸ Estrus synchronization and controlled breeding in cattle, sheep, goats, and swine

▸ Superovulation and multiple ovulation protocols for embryo transfer programs

▸ Fertility enhancement in herds with reproductive inefficiencies or where precise breeding timing is required

Due to its dual gonadotropic activity and relatively long duration of action, PMSG reduces the need for multiple hormone administrations, simplifying dosing regimens and improving operational efficiency in large-scale livestock operations.
