It is usually described as persistent metallic, sour, bitter or other unusual or bad taste in the mouth

Instead, its activity is believed to be mediated via adipocyte-specific signaling cascades, which gives the fragment a uniquely narrow pharmacological footprint for a peptide of its molecular size and makes it attractive to investigators who want clean lipolytic readouts

Studies suggest the peptide may induce lipolysis without significantly affecting insulin or IGF-1 levels in laboratory models, which would, in principle, reduce the glucose-intolerance risk associated with full HGH exposure
