Peptides are short chains of amino acids linked by peptide bonds. Chains of fewer than ten or fifteen amino acids are called oligopeptides, and include dipeptides, tripeptides, and tetrapeptides. A polypeptide is a longer, continuous, unbranched peptide chain.

Growth-hormone-releasing hormone (GHRH, somatoliberin) is the hypothalamic peptide hormone that specifically stimulates synthesis and release of growth hormone (GH, somatotropin) by somatotrope cells of the anterior pituitary gland. GHRH is the last of the classically postulated hypothalamic hormones to be characterized, synthesized, and used in clinical medicine. – NCBI

Growth hormone-releasing peptides (GHRPs) constitute a group of small synthetic peptides that stimulate the growth hormone secretion and the downstream axis activity. Mounting evidences since the early 1980s delineated unexpected pharmacological cardioprotective and cytoprotective properties for the GHRPs. – NCBI

Growth hormone-releasing peptides and non-peptides (GHRPs. GHRP-GHS) are a new chemical class of GH secretagogues with a chemistry that ranges from small synthetic peptides to peptidomimetics. They release GH in animals and humans by a unique dual and complementary action on the hypothalamus and pituitary. Although the present GHRPs are of unnatural origin, evidence by a number of investigators is gradually accumulating to support that GHRP reflects the GH-releasing action of a new natural hypothalamic hormone yet to be isolated and identified

“Our peptide programs are centered towards improving quality of life, and in some ways turning back the hands of time. Age related aches, tissue injuries, and inflammatory conditions can often be reversed. Exercise performance can improve, and when combined with hormone replacement therapy, patients often tell me they feel they have their lives back.” – David Douglas PA-C
