What is HMG?
HMG (Human Menopausal Gonadotropin (FSH+LH)) is a Purified urinary glycoprotein (FSH + LH). Purified urinary gonadotropin preparation with both FSH (follicle-stimulating hormone) and LH (luteinizing hormone) receptor-activating activity. FSH-R activates Sertoli cells and ovarian granulosa cells; LH-R (LHCGR) activates Leydig cells and corpus luteum. Used in ART, hypogonadism, and reproductive endocrinology research.
Research Applications
FSH+LH Co-stimulation

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
