Growth Hormone Research Peptides

The growth hormone (GH) category encompasses several well-characterized peptide classes used in endocrinology research: GH-releasing hormone (GHRH) analogs, growth hormone secretagogues (GHS), and recombinant GH itself. CJC-1295 and Ipamorelin are the most extensively studied compounds in this category, frequently examined together in research protocols due to their complementary mechanisms — CJC-1295 acting through the GHRH receptor and Ipamorelin acting through the ghrelin/GHS receptor system.

What to look for in this category

GH secretagogues are particularly sensitive to purity issues — small amounts of synthesis byproducts can interfere with receptor binding studies and skew dose-response curves. Look for vendors that provide both HPLC purity (>=98%) and MS identity confirmation. Storage matters too: lyophilized GH peptides should ship cold and arrive intact, with the vial appearing as a uniform white powder cake.
