GHRP-6 (Growth Hormone Releasing Peptide – 6) is a hexapeptide with a chain comprised of 6 amino acids. It is one of several synthetic met-enkephalin analogs that include unnatural D-amino acids that were developed for their growth hormone releasing activity and are called growth hormone secretagogues. GHRP-6 is a true HGH secretagogue.
Melanotan-2 (MT-2) is a synthetic analogue of alpha-melanocyte-stimulating hormone. Developed in the 1980s, Melanotan-2 has been shown to increase sexual arousal, reduce compulsive/addictive behavior, curb hunger and increase melanin production. Research has shown the peptide to stimulate melanocytes therefore producing increased skin pigmentation and may help to combat autism when used during early childhood development.
