The non-selective receptor activation profile makes Melanotan II a useful tool for studying the broader melanocortin system in published preclinical research
The experiment measured how these neurons potentially reacted to three substances: ARA-290, capsaicin (the compound that makes chili peppers hot), and KCl (a common chemical compound that can be used as a control)
The peptide is seen to mimic the action of the human growth hormone (HGH)
Joint pain, stiffness, swelling, and reduced mobility often affect sleep, exercise, work, and overall quality of life
These findings are from preclinical research and have not been confirmed in human clinical trials
Both contain the same 15-amino-acid peptide core
