CJC-1295 is a tetrasubstituted GHRH(1–29) analog engineered for extended half-life (~6–8 days) via protection from enzymatic degradation and reversible albumin binding[1]. A single dose can sustain elevated GH for approximately 6 days and IGF-1 elevation for 9–11 days. GHRP-2 is a synthetic hexapeptide ghrelin-mimetic that binds the GH secretagogue receptor (GHS-R1a), triggering acute GH pulses that peak within ~25 minutes[3]. Combining CJC-1295’s sustained GHRH signaling with GHRP-2’s rapid secretagogue action produces synergistic GH release that exceeds either peptide alone[6].
