CJC-1295 Whit DAC

Buy CJC-1295 With DAC: Long-Acting GHRH Analog Research Peptide

Are you looking to buy CJC-1295 with DAC from a manufacturer that verifies purity on every batch? Sino Research Peptide Manufacturer supplies CJC-1295 DAC, a synthetic 29-amino-acid analog of growth hormone-releasing hormone (GHRH). Researchers posit this peptide may function similarly to GHRH, potentially increasing endogenous growth hormone (GH) production within experimental models.(1)

What Is CJC-1295 With DAC?

Buy CJC-1295 With DAC stands as the shortest functional GHRH analog that still holds the potential capacity to trigger GH release from somatotroph cells in the pituitary gland. Four of the original 29 amino acids in this fragment are substituted, a modification researchers believe may improve pharmacokinetics and prolong the peptide’s half-life.

What Makes DAC Different?

The DAC component is a biochemical complex that may further extend the peptide’s half-life, potentially through its ability to bind plasma proteins. More precisely, DAC involves attaching a lysine derivative — N-epsilon-3-maleimidopropionamide — to the C terminus of CJC-1295 DAC. This modification may extend the peptide’s half-life to approximately 8 days while maintaining strong affinity for GHRH receptors, similar to CJC-1295 without DAC.(2)

This doesn’t mean CJC-1295 without DAC lacks relevance in current research. For example, researchers have studied CJC-1295 without DAC combined with Ipamorelin for its suggested synergistic potential, since pairing GHRH analogs with ghrelin receptor-activating peptides may result in a greater GH-synthesis response from somatotroph cells.(3)

What Is Buy CJC-1295 With DAC Used For in Research?

CJC-1295 DAC goes by several names in scientific literature: CJC-1295, CJC-1295 with DAC, DAC:GRF, long-acting GHRH analog, and synthetic GHRH analog. As a theorized growth hormone releasing factor, researchers have studied its potential role in:

• Reducing fat mass by promoting fat cells as an energy source, potentially increasing muscle mass through protein synthesis promotion
• Supporting bone mass and joint/connective tissue health, since growth hormone is associated with bone growth
• Supporting nervous system sleep centers, mirroring GHRH’s suggested role in sleep regulation(4)

Chemical Makeup of CJC-1295 DAC

CJC-1295 DAC Mechanism of Action: What Research Shows

Researchers conducted two clinical studies in 2006 examining CJC-1295 DAC’s mechanism of action. The first study presented ascending concentrations of the peptide or a placebo, while the second study presented a single concentration repeatedly. Results showed an apparent increase in GH and insulin-like growth factor-1 (IGF-I) levels among research models following CJC-1295 DAC introduction.(5)

Researchers believe CJC-1295 DAC elevates IGF-1 by increasing growth hormone production, which may bind to receptors on liver cells and trigger intracellular signaling. This binding might activate the JAK-STAT signaling pathway, potentially leading STAT proteins to migrate to the nucleus and attach to DNA response elements, resulting in IGF-I gene transcription. Researchers theorize that IGF-I produced in liver cells transports to various target tissues, and many tissues carry GH receptors capable of producing IGF-I locally upon activation.

Preliminary exposure to CJC-1295 DAC in experimental models has been associated with a 2- to 10-fold increase in average growth hormone levels for 6 days or longer. Researchers also observed dependent increases in average IGF-I levels of 1.5- to 3-fold for about 9–11 days, with IGF-I levels potentially remaining elevated for at least two weeks. Following repeated exposure, average IGF-I levels appeared to stay elevated above baseline for up to 28 days, suggesting a cumulative effect.(5)

A separate 2006 study assessed GH pulsatility following a single CJC-1295 DAC presentation, finding roughly a 50% increase in mean GH secretion and IGF-I levels.(6) Researchers suggested the peptide might contribute to peak growth hormone level increases of up to 7.5 times in studied models.(6)

CJC-1295 DAC appears to interact with binding sites on the GHRH receptor protein, potentially triggering structural changes that stimulate intracellular G-proteins.(7) Upon activation, these proteins may promote secondary messengers like cAMP or IP3, which play key roles in cellular signaling.(8) These messengers are thought to activate protein kinases, which regulate cellular functions by phosphorylating transcription regulators. Once phosphorylated, these regulators may move into somatotroph cell nuclei, influencing genes involved in growth hormone production.

Animal Studies on Body Composition

Researchers evaluated murine models presented with either CJC-1295 DAC or a placebo. Daily exposure appeared to completely normalize growth, while presentation every 2–3 days produced intermediate results, suggesting an interval-dependent action.(9)

This research also suggests CJC-1295 DAC might impact body composition by increasing muscle tissue hypertrophy without increasing, or possibly even reducing, fat tissue levels. In GHRH-gene-deleted murine models (GHRHKO), CJC-1295 DAC exposure appeared to preserve normal lean mass levels and keep subcutaneous fat mass consistent with control levels — unlike unexposed GHRHKO models, which showed increased fat levels.

Researchers also noted a possible increase in pituitary RNA and GH mRNA levels following exposure, suggesting enhanced somatotroph cell presence. As the study authors noted, CJC-1295 caused an increase in total pituitary RNA and GH mRNA, indicating that somatotroph cell proliferation had likely occurred, confirmed through immunohistochemistry imaging.(9)

CJC-1295 DAC Peptide Half-Life

CJC-1295 DAC’s original form uses Drug Affinity Complex (DAC) technology.(1) While natural GHRH carries a half-life of roughly 7 minutes, researchers report CJC-1295 without DAC exhibits a longer 30-minute half-life due to its truncated, modified amino acid sequence.

Four specific structural alterations are believed to improve the peptide’s stability against dipeptidyl peptidase-4 breakdown:

• Position 2: L-alanine substituted with D-alanine, bolstering resistance to enzymatic degradation
• Position 8: Asparagine replaced with glutamine, potentially reducing asparagine rearrangement and amide hydrolysis risk
• Position 15: Glycine substituted with alanine, theorized to enhance bioactivity
• Position 27: Methionine altered to leucine, potentially preventing methionine oxidation

These modifications work together to enhance the peptide’s resilience under laboratory conditions. With DAC technology added, the half-life extends further to 6–8 days.(10)

CJC-1295 DAC Ancillary Research

In 2005, a clinical study aimed to evaluate CJC-1295 DAC’s mechanism of action in models associated with HIV-related visceral obesity, planning three months of exposure followed by a six-week follow-up. This study was terminated during recruitment, and no related results were published.(11)

A 2009 Norwegian study from the Norwegian Doping Control Laboratory and School of Pharmacy analyzed a submitted compound to determine whether it contained prohibited substances. Researchers identified the substance as CJC-1295 DAC and concluded in their published article that CJC-1295 DAC functions as a releasing factor for growth hormone.(1)
