What Is CJC-1295 No DAC and Why Buy It for Research?
Buy CJC-1295 No DAC in Switzerland for research into pulsatile growth hormone release, GHRH receptor signaling, and physiological GH axis dynamics. Specifically, CJC-1295 No DAC (also known as Modified GRF 1-29, Mod GRF 1-29, or GRF(1-29) NH₂) is a synthetic 29-amino acid peptide analog of growth hormone-releasing hormone (GHRH).
Structurally, it features the sequence Tyr-D-Ala-Asp-Ala-Ile-Phe-Thr-Gln-Ser-Tyr-Arg-Lys-Val-Leu-Ala-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Leu-Ser-Arg-NH₂ with a molecular weight of approximately 3,367.9 Da.
CJC-1295 No DAC represents the active peptide component of the CJC-1295 platform without the Drug Affinity Complex (DAC) moiety that enables albumin binding. This distinction is pharmacologically critical: without the DAC, the peptide has a plasma half-life of approximately 30 minutes rather than 6 to 8 days. Furthermore, the peptide incorporates four strategic amino acid substitutions D-Ala at position 2, Gln at position 8, Ala at position 15, and Leu at position 27 that confer resistance to dipeptidyl peptidase-IV (DPP-IV) and other plasma proteases.
The D-Ala substitution at position 2 is the most critical modification, as native GHRH is rapidly inactivated by DPP-IV which cleaves the Tyr1-Ala2 peptide bond. Consequently, this single modification extends the biological half-life from less than 7 minutes (native GHRH) to approximately 30 minutes. Moreover, Core Peptides supplies CJC-1295 No DAC as a lyophilized powder in a 5mg format exclusively for laboratory use. Therefore, researchers seeking to source this pulsatile GHRH analog for their work will find it readily available when they buy CJC-1295 No DAC in Switzerland.
CJC-1295 No DAC Research Overview: Buy CJC-1295 No DAC in Switzerland for Pulsatile GHRH Studies
Centrally, research into CJC-1295 No DAC has focused on its function as a short-acting GHRH analog that produces discrete, physiological GH pulses similar to natural GHRH signaling. Endogenously, growth hormone-releasing hormone (GHRH) stimulates the pituitary gland to release growth hormone (GH) in a pulsatile manner, which is essential for normal growth, metabolism, and physiological function. However, the native GHRH peptide has an extremely short half-life of less than 7 minutes due to rapid enzymatic degradation by DPP-IV, limiting its utility as a research tool.
CJC-1295 No DAC overcomes this limitation through four strategic amino acid substitutions that confer resistance to DPP-IV and other plasma proteases, extending the half-life to approximately 30 minutes. Unlike the DAC-conjugated version which produces sustained elevation, the no-DAC variant produces a short, sharp GH pulse lasting approximately 1-2 hours per injection, closely mimicking the natural, pulsatile release of GHRH.
This rapid clearance allows GH to return to baseline between doses, preserving the physiological on/off pattern of GH secretion. Notably, CJC-1295 without DAC and modified GRF 1-29 refer to the same tetra-substituted GHRH (1-29) sequence the stabilised backbone without the albumin-binding DAC group. Accordingly, researchers who buy CJC-1295 No DAC in Switzerland from Core Peptides can support their investigations into pulsatile GHRH signaling, physiological GH dynamics, and synergistic peptide combinations.
How Does CJC-1295 No DAC Work in Research?
Mechanistically, CJC-1295 No DAC operates through GHRH receptor activation with a pulsatile pharmacokinetic profile that closely mimics endogenous signaling.
GHRH Receptor Activation
CJC-1295 No DAC functions as a GHRH analog that binds to and activates the GHRH receptor (GHRH-R) on anterior pituitary somatotrophs. This binding triggers a downstream signaling cascade via Gs/cAMP/PKA signaling that results in GH synthesis and secretion.
The peptide is derived from the biologically active N-terminal fragment of human GHRH (residues 1-29), which represents the minimum sequence required for full agonist activity at the GHRH receptor. Additionally, the peptide is C-terminally amidated (CONH₂ rather than COOH), consistent with the natural processing of GHRH, contributing to improved metabolic stability by preventing carboxypeptidase degradation.
DPP-IV Resistance
The four strategic amino acid substitutions in CJC-1295 No DAC confer resistance to enzymatic degradation. Specifically, the D-Ala substitution at position 2 introduces a non-natural amino acid configuration that DPP-IV cannot recognize, rendering the peptide resistant to this primary degradation pathway.
Furthermore, the Gln substitution at position 8 (replacing Asn) prevents non-enzymatic deamidation, preserving receptor binding and improving shelf stability. The Ala substitution at position 15 (replacing Gly) enhances metabolic stability by reducing susceptibility to endopeptidases. Moreover, the Leu substitution at position 27 (replacing Met) prevents oxidation of the sulfur atom, providing improved chemical stability.
Pulsatile GH Release Profile
With a half-life of approximately 30 minutes, CJC-1295 No DAC produces discrete 1-2 hour GH pulses per injection that closely mimic endogenous pulsatile GH secretion. GH returns to baseline between doses, preserving the physiological on/off pattern that is essential for normal GH axis function. As a result, this pulsatile profile contrasts with the sustained elevation produced by the DAC-conjugated version.
Why Is CJC-1295 No DAC Studied in Switzerland?
Primarily, researchers study CJC-1295 No DAC because it represents a well-characterized short-acting GHRH analog that enables investigation of pulsatile GH secretion, physiological GHRH signaling, and synergistic peptide combinations. In fact, this compound offers a focused tool for studying the molecular mechanisms underlying physiological GH dynamics, somatotroph function, and growth hormone axis regulation.
Research has demonstrated CJC-1295 No DAC’s relevance across multiple domains. For instance, the no-DAC variant is the typical pairing partner with GHRPs such as Ipamorelin because its 30-minute half-life matches Ipamorelin’s approximately 2-hour half-life, which preserves a pulsatile pattern. Furthermore, studies have suggested that GHRH may support the centers in the nervous system for sleep.
The non-DAC version produces physiological pulsatile GH release with rapid clearance and better safety reversibility, but requires multiple daily injections. The choice between DAC and no-DAC forms depends on the specific research question: for studies requiring sustained elevation of GH to investigate long-term effects, CJC-1295 with DAC is often preferred; for experiments aiming to mimic the natural physiological rhythm of GH secretion, CJC-1295 without DAC is the more appropriate choice.
Additionally, CJC-1295 No DAC has been identified in seized doping material as a modified growth hormone releasing factor that can be used as a performance-enhancing substance in sports. Ultimately, researchers who buy CJC-1295 No DAC in Switzerland gain access to a comprehensive research tool for investigating pulsatile GHRH signaling, physiological GH dynamics, and GHRP synergy.
