Protirelin, also known as thyrotropin-releasing hormone (TRH), causes the secretion of thyroid-stimulating hormone (TSH) from the anterior pituitary gland. TSH acts on the thyroid gland to release the thyroid hormones thyroxine (T4) and triiodothyronine (T3).http://www.creative-peptides.com/product/protirelin-item-10-101-51-91.html
