CJC-1295 / Ipamorelin

CJC-1295 with DAC and Ipamorelin are two peptides that work on completely separate receptor systems within the same organ — the pituitary gland. Their combination produces 40% greater growth hormone elevation than either compound alone, addressing the core hormonal decline that drives every major aging marker in companion animals.

How it works.

CJC-1295 with DAC is a synthetic analog of growth hormone releasing hormone (GHRH). The DAC (Drug Affinity Complex) modification adds an albumin-binding domain that makes the peptide invisible to the enzyme (DPP4) that would otherwise destroy it within minutes. Once bound to albumin — the most abundant protein in the bloodstream — CJC-1295 circulates for 7–14 days per injection, providing consistent pituitary stimulation.

Ipamorelin works on the ghrelin receptor (GHSR1A) — a completely different pathway from CJC-1295. This dual-pathway stimulation is critical: hitting only one receptor causes rapid tachyphylaxis (adaptation). Activating both pathways simultaneously slows this adaptation and produces a compounded signaling effect. The result is 40% greater GH output than either compound alone.

The downstream GH and IGF-1 elevation drives: increased lean mass through satellite cell activation, improved insulin sensitivity through GLUT4 translocation, enhanced mitochondrial biogenesis through PGC-1alpha upregulation, and improved immune function through NK cell and T-cell activation.

GH Elevation vs. Single Peptide
Combined GHRH + ghrelin receptor stimulation produces 40% greater GH output than either compound alone, confirmed in human and animal models.

Duration Per Injection (CJC with DAC)
Albumin binding extends CJC-1295 with DAC half-life to one to two weeks per injection, providing consistent pituitary stimulation from a single weekly dose.

Satellite Cell Activation
IGF-1 elevation activates muscle satellite cells (stem cells), expanding myonuclei count and permanent protein synthesis capacity.

CJC-1295 with DAC and Ipamorelin are administered separately. CJC-1295 with DAC is dosed once weekly. Ipamorelin is dosed three times per week, ideally before sleep to align with the natural GH pulse. Do not administer within 30 minutes of feeding. Reconstitute each vial separately.
