THE HEART OPTIMIZER
Pyr¹-Apelin-13 (short isoform), Apelin fragment 12
Apelin-12 is a naturally occurring peptide that acts as a powerful cardiovascular regulator. It improves blood flow, strengthens heart contractions, and enhances how your body processes glucose, all without increasing oxygen demand on the heart. It's being studied for heart failure, metabolic syndrome, and as an anti-aging compound.
