Another difference in Melanotan (opposed to Melanotan II) is that the linear peptide does not cross the blood brain barrier (BBB). By not crossing the BBB, Melanotan will not affect the MCR3 or MCR4 receptors in such a way Melanotan II would. Therefore it should not impact your eyes, appetite or blood pressure (positively or negatively). Furthermore it is noted that users do not report joint pain, headaches or fatigue from the original Melanotan. These are big selling points.

Great stuff right there Vette. I've appreciated all of your posts about this stuff over the last 1.5 years.
