Here at Licensed Peptides, we supply CJC-1295 DAC for research use only. We use a 6-point verification process to ensure you receive a reliable CJC-1295 peptide that you can use for both short and long-term studies.
We understand the importance of purity and sterility in research compounds; that’s why we manufacture our CJC-1295 under strict quality standards in GMP-certified facilities, after which independent, accredited laboratories verify its quality.
Our 6-point Quality Verification Process:
• A High-Performance Liquid Chromatography (HPLC) analysis to check for 99%+ purity
• Mass spectrometry to confirm the molecular identity of each peptide and whether its sequence is accurate
• Screening for heavy metals and endotoxins, including lipopolysaccharides (LPS)
• Verification of sterility through an ISO/IEC 17025:2017-accredited laboratory
• Our team also confirms that the content (weight and concentration) is accurate
• Lastly, we physically inspect every vial for lyophilization quality, label accuracy, and overall appearance
CJC-1295 is a modified analog of human growth hormone-releasing factor 1-29, or hGRF(1-29) (1-29 means it’s a chain of 29 amino acids). Researchers developed it to retain activity at the GHRH receptor while remaining detectable in circulation longer than unmodified hGRF(1-29).¹
CJC-1295 is among the most studied peptides because of its ability to stay in circulation longer. Researchers investigate it to better understand how modifications in structure influence the stability of peptides and endocrine signaling. Current areas of research include:
• Growth Hormone-Releasing Hormone (GHRH) receptor pharmacology
• Pituitary signaling pathways
• Peptide pharmacokinetics
• Albumin-binding mechanisms
• Long-acting peptide engineering
• Structure-activity relationship studies
• Research pertaining to endocrine signaling
• Molecular stability and peptide disposition
The presence of Drug Affinity Complex (DAC) has made CJC-1295 valuable, particularly in studies investigating how different ways of synthesizing peptides can affect circulation time and interaction with different receptors.
Albumin is the most abundant protein in blood plasma, and one of its primary roles is to transport molecules throughout the body while protecting them from rapid degradation.2 Researchers continue to investigate how DAC enables CJC-1295 to bind to circulating albumin, thereby reducing the rate at which it’s removed from circulation.
This is one of the common areas of study for CJC-1295. One original preclinical study found that albumin-conjugated hGRF analogs retained activity at the GRF receptor in rat models.1 This study set the precedent and made the CJC-1295 peptide useful for examining how structural modifications affect the activity of growth hormone receptors.
CJC-1295 provides researchers with a model for studying how amino acid substitutions and albumin conjugation affect peptide absorption, distribution, persistence, and exposure to receptors. The foundational preclinical work focused on molecular design and albumin bioconjugation, while later studies investigated its extended pharmacokinetic and endocrine signaling profile.1,2,4,5 Researchers continue to investigate these areas of study.

CJC-1295 is a synthetic Growth Hormone-Releasing Hormone (GHRH) analog developed for laboratory research. Researchers continue studying it in studies about receptor pharmacology, peptide engineering, and pharmacokinetics.
DAC stands for Drug Affinity Complex. This is a molecular modification designed to prolong its circulation by enabling covalent conjugation with serum albumin.
CJC-1295 is a synthetic peptide derived from Growth Hormone-Releasing Hormone (GHRH). It’s made to mimic endogenous GHRH (which signals the body to release Growth Hormone), and also to improve its stability and resistance to degradation.
DAC stands for Drug Affinity Complex, which is a proprietary molecular modification that was developed to help peptides remain in circulation for longer during research. Better stability means researchers can study the effects of CJC-1295 within the body for longer periods of time.
Interested in a version with no DAC? Our verified CJC-1295 No DAC (also called ModGRF 1-29) is made with the same attention to quality and research-grade standards.
For researchers exploring related GHRH analogs or growth hormone secretagogues, our collection also includes compounds such as Ipamorelin, Sermorelin, and Tesamorelin, as well as peptide blends like CJC-1295 No DAC + Ipamorelin.
CJC-1295 contains the Drug Affinity Complex (DAC), whereas MOD GRF 1-29 does not. The presence of DAC produces important differences in peptide pharmacokinetics and plasma persistence, and as such, makes the two compounds suitable for different areas of laboratory investigation.
Published research investigates CJC with DAC in areas including:
• GHRH receptor pharmacology
• Endocrine signalling
• Pituitary biology
• Peptide pharmacokinetics
• Albumin conjugation
• Long-acting peptide engineering

Which Analytical Tests Does Licensed Peptides Perform on CJC-1295?
We perform the following tests to verify quality:
• HPLC purity analysis
• Mass spectrometry identity verification
• Heavy metal screening
• Endotoxin and LPS testing
• Visual quality inspection
Endotoxin Note: We screen our CJC-1295 peptides for heavy metals, endotoxins, and lipopolysaccharides (LPS) at the compound level. Full LAL testing results are available within the product Certificate of Analysis.
HPLC separates peptide material from impurities. A reported purity of 99%+ indicates that at least 99% of the analyzed sample consists of the target peptide.
Store unopened lyophilized vials at -20°C for long-term preservation. After reconstitution, refrigerate below 4°C and avoid repeated freeze-thaw cycles.
No. We supply CJC-1295 exclusively for laboratory, analytical, and scientific research. It is not approved for human consumption, therapeutic use, veterinary applications, or diagnostic procedures.
Researchers choose Licensed Peptides because every batch of CJC with DAC includes:
• 99%+ HPLC-verified purity
• Independent third-party testing
• Mass spectrometry identity confirmation
• Heavy metal and endotoxin screening
• Batch-specific Certificates of Analysis
• GMP-certified U.S. manufacturing
• Same-day domestic shipping
• Responsive U.S.-based research support
Lyophilization removes water from the peptide under low-temperature, low-pressure conditions, producing a stable white powder.
Because moisture is removed during manufacturing, lyophilized peptides generally demonstrate greater stability during storage than peptides supplied in solution.
