HMG 75 IU research material

Buy HMG 75 IU for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial. Human menopausal gonadotropin, also called menotropin, is a gonadotropin preparation; the IU label describes activity rather than milligrams.

Activity and composition are different specifications

HMG preparations are associated with follicle-stimulating hormone (FSH) and luteinizing hormone (LH) activity. They are not one short synthetic peptide with a single sequence, molecular formula or molecular weight.

The 75 IU label describes activity units, not 75 mg of protein. FSH and LH activity are separate measurements. A protocol that depends on their ratio requires the individual values for the preparation used.

HCG 5000 IU is a different listing. Although HCG can be relevant to LH-associated activity, HCG and HMG are not equivalent preparations, and their IU labels cannot be compared as if they were weights of the same compound.

Why preparation identity matters

In a 2024 analytical study by Capolupo and colleagues, liquid chromatography and mass spectrometry were used to characterize glycoprotein components in commercial highly purified HMG preparations. The researchers examined FSH, LH and HCG-related profiles, including attached carbohydrate structures.

That work illustrates the difference between an activity label and a detailed protein profile. Its findings describe the commercial preparations analyzed in the study.

Review the supplied product records

Use Documents to review available files. Check whether the records address material identity, the basis of the activity result and any individual hormone measurements needed for the experiment. An HPLC purity figure alone is not an FSH or LH activity assay.

Follow storage and handling information for the complete preparation. The 3 mL specification is vial capacity, separate from the 75 IU label; it does not specify liquid supplied or a preparation volume.
