PT-141 (Bremelanotide)- Summary
- Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.
- PT-141 (Bremelanotide) is a cyclic peptide melanocortin receptor agonist that enhances sexual desire and arousal through central nervous system mechanisms. It is FDA-approved as Vyleesi for premenopausal women with hypoactive sexual desire disorder (HSDD).
