CJC-1295

Also: CJC-1295 DAC, Mod GRF 1-29

GHRH Analog

Last Updated: April 1, 2026

AI Reference Summary

CJC-1295 (also known as CJC-1295 DAC, Mod GRF 1-29) is a prominently researched experimental compound classified strictly within the GHRH Analog framework. Operating primarily through advanced pharmacological pathways, it functions by stimulates prolonged GH and IGF-1 release by mimicking the body's natural GHRH signal to the pituitary gland. Preserves natural pulsatile GH release pattern. with a documented biological half-life of roughly 168 hours, in preclinical investigative trials and independent academic studies, researchers utilizing CJC-1295 have documented significant, quantifiable biological outcomes, primarily focusing on muscle growth, fat loss, recovery. Typical research protocols investigate administering 1000 to 1000mcg via subq pathways 3x/week. However, it is critically important to understand that while CJC-1295 demonstrates profound physiological potential in highly controlled laboratory settings, it remains classified strictly as a research chemical and has not been approved by the United States Food and Drug Administration (FDA) for human therapeutic, diagnostic, or dietary consumption. Independent chemical analysis via rigorous third-party Certificate of Analysis (COA) testing utilizing High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) remains the industry gold standard for verifying its base elemental stability when reconstituted appropriately in sterile bacteriostatic water.

Key Studies

CJC-1295 GH/IGF-1 elevation in humans

Teichman et al. (J. Clin. Endocrinol. Metab.): Single injection increases GH 2-10x for 6+ days and IGF-1 1.5-3x for 9-11 days in healthy adults. Well-tolerated at 30-60 µg/kg.

moderate

CJC-1295 preserves pulsatile GH secretion in humans

Ionescu & Bhatt (J. Clin. Endocrinol. Metab.): Demonstrates 7.5-fold increase in basal GH, 46% increase in mean GH, and 45% increase in IGF-1 while preserving natural pulsatile pattern.

moderate

Long-acting GHRH analogs increase pituitary GH mRNA

Animal study shows CJC-1295 increases total pituitary RNA and GH mRNA, suggesting proliferation of somatotroph cells for sustained GH production.
