The combination of CJC 1295 NO DAC and Ipamorelin—commonly referred to as the CJC/Ipamorelin Blend—has become a core focus in peptide science due to its dual-pathway engagement with growth hormone signaling. This growth hormone peptide stack merges a GHRH analog (CJC 1295 NO DAC) and a GHRP (Ipamorelin) to support advanced research into endocrine processes, pituitary modulation, and GH release dynamics.
In this article, we’ll break down the structure, mechanisms, synthesis, purity standards, and relevance of the CJC & Ipamorelin peptide complex for laboratory environments. Whether you’re exploring peptide blends or just diving into growth hormone releasing peptides, understanding how these compounds interact is key for experimental integrity.
Introduction to CJC/Ipamorelin Peptide Blends
Peptide research has become increasingly refined with the advent of synergistic stacks such as CJC-1295 + Ipamorelin. These blends offer a two-pronged approach to GH pathway stimulation, allowing researchers to evaluate multiple receptor interactions within a single controlled study.
Many researchers are currently studying the effects of CJC1295 Ipamorelin combos on pulsatile hormone release and endocrine signaling in preclinical models. With more laboratories investing in lab-grade peptides, clarity around structure and mechanism is essential for replicability and scientific progress.
What Is the CJC/Ipamorelin Blend?
The Combo Defined
The CJC/Ipamorelin blend consists of:
-
CJC 1295 NO DAC: A GHRH analog that activates GHRH receptors to support pituitary GH secretion in rhythmic patterns.
-
Ipamorelin: A GHRP that selectively targets the ghrelin receptor (GHS-R1a), promoting GH release with minimal off-target effects.
Together, they function as a Peptide GH Release Formula, supporting experimental work in feedback loop dynamics, GH pulse studies, and multi-receptor interaction modeling.
Popular Uses in Research:
-
Analyzing GH pulsatility and amplitude
-
Investigating pituitary responsiveness
-
Studying GH/IGF-1 pathway interactions
-
Testing receptor binding specificity and desensitization
Mechanism of Action
Dual Receptor Pathway
CJC and Ipamorelin activate two distinct growth hormone pathways:
-
GHRH receptor activation by CJC 1295 NO DAC
-
Ghrelin receptor (GHS-R1a) activation by Ipamorelin
These two signals converge at the anterior pituitary, providing a compounded GH release during specific research protocols.
Why Use a Blend?
The synergy achieved from combining these peptides is of particular interest for laboratories looking to model physiological GH rhythms more closely than single-agent studies allow.
-
GHRH-based analogs mimic natural hypothalamic triggers
-
GHRPs like Ipamorelin simulate ghrelin’s potentiating effects on GH release
The result is a more comprehensive peptide complex that expands the versatility of GH-related research studies.
Structure and Technical Details
Molecular Composition
-
CJC 1295 NO DAC: 30-amino-acid peptide (MW ~3364 Da)
-
Ipamorelin: Pentapeptide (MW ~711 Da)
Both peptides are synthesized via solid-phase peptide synthesis (SPPS), lyophilized, and delivered in sterile vials for lab use. They require proper reconstitution with bacteriostatic water under aseptic conditions.
Reconstitution & Storage
-
Store lyophilized peptides at -20°C or colder
-
After reconstitution, peptides should be kept refrigerated (2–8°C)
-
Use within a short window to ensure potency and integrity

Why Use CJC 1295 NO DAC?
The NO DAC version is preferred for researchers seeking short-acting GHRH analogs. Without the Drug Affinity Complex, CJC 1295 NO DAC produces GH pulses similar to natural cycles, unlike the DAC-bound version which results in prolonged, non-pulsatile stimulation.
Learn more about the CJC NO DAC peptide and how it differs in research structure from DAC-containing analogs.
Why Choose Ipamorelin?
Ipamorelin is favored in modern peptide science due to its selective binding to ghrelin receptors with minimal interaction with cortisol or prolactin pathways. Researchers studying the selective GH stimulation process often rely on Ipamorelin’s precision in receptor targeting.
