Peptide Comparison

FSH vs Triptorelin

Q: What is the difference between FSH and Triptorelin?

FSH: Binds FSH receptors on Sertoli cells in testes to support sperm maturation and inhibin B production. In women, binds granulosa cell FSH receptors to drive follicular growth and estradiol production. Triptorelin: Potent GnRH agonist; single pulse stimulates LH/FSH surge and restores HPG axis after suppression (e.g., post-steroid cycle)

Both are Reproductive & Hormonal peptides.
