It is commonly described in the scientific literature as a stable gastric pentadecapeptide, reflecting both its biological origin and its unusual stability under experimental conditions

It: Does not affect liver enzymes Has no renal toxicity Does not cause stimulant effects Does not disrupt appetite or hormones Is non-habit forming That said, always consult a qualified healthcare provider before starting any new peptide protocol
