Frag 176-191, or human growth hormone (176-191) in research is primarily used as a replacement therapy for those dealing with growth hormone deficiencies. In its natural form, this peptide is created and comes from somatotropic cells that are located in the anterior pituitary gland. In its synthetic form, researchers have found that Frag 176-191 is able to aid in weight and fat control as well as improve an individual’s bone strength and muscle recovery. -------------------------------------
