Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), composed of 44 amino acids with the molecular formula C221H366N72O67S and a molecular weight of 5,135.9 g/mol. It is also known by the research designation TH9507 (CAS 218949-48-5). Its structure is identical to naturally occurring human GHRH, except for a trans-3-hexenoic acid group added to the tyrosine at position 1,…

This blend pairs Tesamorelin with Ipamorelin. Tesamorelin is a 44-amino-acid synthetic analog of growth hormone-releasing hormone (GHRH), formed by adding a trans-3-hexenoic acid group to the native GHRH(1-44) sequence. It has a molecular weight of 5135.9 g/mol and CAS number 901758-09-6. Ipamorelin is a pentapeptide — five amino acids — with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂, a molecular weight of 711.86 g/mol,…

Thymulin is a nonapeptide — a chain of nine amino acids — produced by epithelial cells in the thymus gland. It was first isolated and characterized in 1977 and has the sequence Pyr-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn, with a molecular weight of approximately 858 g/mol (without zinc). Its molecular formula is C₃₃H₅₄N₁₂O₁₅. Thymulin is chemically unique among thymic peptides because it requires a zinc…
