CJC-1295 NO-DAC

This product is not intended for weight loss, human consumption, or veterinary use. It is sold for research purposes only. Please handle with care and follow all safety guidelines for the specific chemicals involved.

CJC-1295 No DAC (also known as Mod GRF 1-29 or Modified GRF 1-29) is a synthetic analog of growth hormone-releasing hormone (GHRH) studied for its effects on GH and IGF-1 secretion in preclinical models. In rat models, this research peptide provides a tool for investigating endocrine regulation, growth axis signaling, and metabolic pathways. A study by Ionescu and Frohman (2006) demonstrated that CJC-1295 administration in rats led to increased GH secretion while preserving the natural pulsatile release pattern. This suggests that the peptide enhances GH levels without disrupting the physiological rhythm of hormone release, which is crucial for maintaining homeostasis.

Further research by Teichman et al. (2006) explored the pharmacokinetics and pharmacodynamics of CJC-1295 No DAC. Their findings indicated that a single subcutaneous injection in study subjects resulted in sustained elevations of GH and IGF-1 levels for several days, highlighting the Mod GRF 1-29 peptide’s extended activity profile in research models. In a study using growth hormone-releasing hormone knockout (GHRHKO) mice, Alba et al. (2006) found that daily administration of CJC-1295 No DAC normalized growth parameters and body composition in the research model. These findings contribute to the understanding of GHRH analog activity in preclinical growth deficit models.

The mechanism behind CJC-1295’s extended half-life involves its bioconjugation with serum albumin, as detailed by Lapierre et al. (2005). This modification allows the Mod GRF 1-29 peptide to remain in circulation longer in research models, supporting its extended activity profile compared to native GHRH. Collectively, these studies support CJC-1295 No DAC (Mod GRF 1-29) as a research tool in endocrinology for investigating GH dynamics and GHRH receptor interactions in preclinical models. NuScience Peptides supplies CJC-1295 No DAC in 5mg and 10mg lyophilized vials, lab tested, for laboratory research use only. Certificates of Analysis are available on the NuScience Lab Test Results page.

Modified Growth Releasing Factor amino acids 1-29, commonly referred to as CJC-1295 No DAC or Mod GRF 1-29, is a synthetic analog of the endogenous GHRH peptide first studied in the 1980s. Preclinical research with Mod GRF 1-29 has examined its effects on muscle tissue repair, wound healing models, bone metabolism, and metabolic regulation in animal studies. Research has also investigated potential effects on glucose regulation and immune system signaling pathways.

Frequently Asked Questions

1What is CJC-1295 No DAC used for in research?

CJC-1295 No DAC (Mod GRF 1-29) is a synthetic GHRH analog studied in preclinical models for its role in GH secretion, IGF-1 production, and endocrine signaling. Research has examined its ability to preserve the natural pulsatile GH release pattern in animal models. NuScience Peptides supplies CJC-1295 No DAC in 5mg and 10mg lyophilized vials for laboratory research use only. Not for human consumption.

2What is the difference between CJC-1295 No DAC and CJC-1295 with DAC?

CJC-1295 No DAC (Mod GRF 1-29) does not carry the Drug Affinity Complex (DAC) modification, resulting in a shorter half-life that preserves natural pulsatile GH release patterns in research models. CJC-1295 with DAC extends the half-life through albumin binding, producing sustained GH elevation. Researchers select between the two based on the protocol requirements of their study.

3What is Mod GRF 1-29?

Mod GRF 1-29 (Modified GRF 1-29) is the same peptide as CJC-1295 No DAC. It is a 29 amino acid GHRH analog featuring four strategic amino acid substitutions that improve its stability against enzymatic degradation compared to native GHRH. It is also referred to as tetrasubstituted GRF 1-29. NuScience Peptides supplies this peptide under the CJC-1295 No DAC designation for laboratory research use only.
