CJC-1295 (No DAC)

CJC-1295 (No DAC) is a synthetic analog of growth-hormone–releasing hormone (GHRH), commonly referred to as modified GRF 1-29. It contains 29 amino acids and is designed to selectively activate the GHRH receptor (GHRHR) on pituitary somatotrophs, supporting research into pulsatile growth hormone secretion, hypothalamic-pituitary GH axis dynamics, and downstream IGF-1 signaling. Unlike CJC-1295 with DAC, the “No DAC” form does not include the drug-affinity-complex modification, giving it a shorter duration of action and making it useful in studies focused on transient GHRH receptor activation.

Mechanism of action

GHRH Receptor Agonism & GH Secretion

CJC-1295 (No DAC) selectively activates the GHRH receptor on pituitary somatotrophs, stimulating adenylate cyclase and the cAMP/PKA signaling cascade. This pathway supports pulsatile growth hormone release in GH-axis research models.

Downstream IGF-1 Signaling

Growth hormone signaling stimulates hepatic and peripheral IGF-1 production, allowing researchers to study downstream anabolic, lipolytic, and tissue-remodeling pathways associated with the GH/IGF-1 axis.

Short-Acting GHRH Analog Profile

Because CJC-1295 (No DAC) lacks the DAC albumin-binding extension, it is shorter acting than DAC-modified CJC-1295. This makes it useful for research models where brief, pulse-like GHRHR activation is preferred over prolonged receptor exposure.
