What's in the cartridge

Pairs Tesamorelin, a DPP-IV-resistant GHRH(1-44) analogue, with the Ipamorelin + CJC-1295 No DAC blend — itself a dual ghrelin- and GHRH-receptor secretagogue combination. Together the two products engage GHRH receptor signalling via two distinct analogues alongside ghrelin receptor stimulation, of interest to researchers studying multi-pathway GH-axis activation and pulsatile release dynamics. Supplied as two separate ready-to-use liquid peptide pens, sold together at a stack discount.
