CJC-1295Ipamorelingrowth hormone
CJC-1295 (with DAC)
A long-acting GHRH analog. The DAC (Drug Affinity Complex) extends half-life to 8+ days, allowing less frequent administration. Produces sustained elevation in growth hormone and IGF-1.
Ipamorelin
A highly selective GHRP that mimics ghrelin. Short half-life (~2 hours). Known for clean GH release with minimal cortisol or prolactin elevation compared to other GHRPs.

Why Combine Them?
CJC-1295 sets the baseline; Ipamorelin triggers the spike. Together they amplify GH output far beyond what either does alone. This is why the stack is a common research combination.
