The availability of these services varies by province and continues to expand as interest in peptide therapy grows
Growth hormone-releasing factor (GHRF), also known as growth hormone-releasing hormone (GHRH), is a hypothalamic peptide that acts on the pituitary somatotroph cells to stimulate the synthesis and pulsatile release of endogenous growth hormone (GH), which is both anabolic and lipolytic
In any situation where carbohydrates are the major energy source, or when glucose is added to the diet, thiamine requirement is increased significantly
In addition, the absence of resistance of peptides to breakdown by gastrointestinal proteolytic enzymes (e.g., carboxypeptidases or aminopeptidases) should be mentioned [8], which in practice precludes administrating such a drug to the patient orally and calls for intravenous administration
