MEGA MASS MIX from ZPHC is a mixture of two peptide compounds (consisting of amino acids) GHRP-6 and CJC-1295 DAC, which synergistically (enhancing each other's action) increase the secretion of growth hormone, thereby significantly increasing your body's ability to build muscle mass, burn fat and heal wounds and injuries. The advantage of this mix of peptides is precisely the synergistic effect, which is many times greater than the effect of each peptide individually.
