Is Gonadorelin a peptide?
Gonadorelin is a research peptide that is the same as gonadotropin-releasing hormone (GnRH) that is naturally released from the hypothalamus gland. GnRH causes the pituitary gland to release other hormones (luteinizing hormone [LH] and follicle-stimulating hormone [FSH]). LH and FSH control development in children and fertility in adults. Gonadorelin helps fertility and helps with menopausal symptoms. It is used for women who have low estrogen levels, have a history of multiple abortions, and have not responded to previous hormone treatments.
