Buy CJC-1295 with DAC 5mg Ireland

Buy CJC-1295 with DAC 5mg in Ireland as a research-grade synthetic peptide for controlled laboratory and scientific research. CJC-1295 with DAC is a modified growth hormone-releasing hormone (GHRH) analogue incorporating a Drug Affinity Complex (DAC) that gives the molecule albumin-binding characteristics and a substantially longer research half-life than short-acting GHRH analogues. The product is supplied strictly for laboratory research use only and is not intended for human or veterinary use.

What Is CJC-1295 with DAC?

CJC-1295 with DAC 5mg is a synthetic peptide analogue related to growth hormone-releasing hormone (GHRH).

The peptide is based on the first 29 amino acids of GHRH with structural modifications designed to improve stability and a C-terminal modification incorporating the Drug Affinity Complex.

The DAC modification is the feature that distinguishes this product from CJC-1295 without DAC.

Research literature has investigated CJC-1295 as a long-acting GHRH analogue, including human pharmacokinetic and endocrine studies. The original clinical research reported prolonged increases in circulating GH and IGF-1 following administration of CJC-1295, demonstrating the long-duration characteristics that made the compound scientifically interesting.

For Research Peptides Ireland, however, the product should remain positioned as a research material, not as a human-use hormone product or treatment.

CJC-1295 with DAC 5mg Product Specifications

Current chemical references identify the DAC conjugate separately from the non-DAC material and report a molecular weight of approximately 3,647.2 Da and CAS 446262-90-4 for the DAC construct.

Important CJC-1295 Identity Note

CJC-1295 is a particularly confusing compound name in commercial peptide catalogues.

Some suppliers list 863288-34-0 and a molecular weight around 3,368 Da while calling the material “CJC-1295 with DAC.” Other current chemical references identify the actual albumin-binding DAC construct as CAS 446262-90-4, with a molecular weight around 3,647.2 Da.

What Does DAC Mean?

DAC stands for Drug Affinity Complex.

The DAC modification is designed to give CJC-1295 an albumin-binding property. Once associated with albumin, the peptide has a much longer residence time than an unmodified short-acting GHRH analogue.

This is the key structural feature separating CJC-1295 with DAC from CJC-1295 without DAC.

For research purposes, this distinction is important because the two materials should not be treated as interchangeable compounds.

CJC-1295 with DAC vs CJC-1295 No DAC

A product labelled simply “CJC-1295” should not automatically be assumed to contain DAC. The DAC status should be explicitly stated and supported by the product documentation.

CJC-1295 with DAC Research Applications

CJC-1295 with DAC has been investigated in research involving:

• GHRH receptor biology
• Growth-hormone signalling
• Peptide pharmacology
• Receptor-ligand interactions
• Long-acting peptide design
• Protein-binding research
• Pharmacokinetic research
• Endocrine signalling
• Peptide structure-function studies

Its long-acting design makes it particularly relevant to researchers investigating how chemical modifications can alter the duration and pharmacokinetic characteristics of peptide molecules.

CJC-1295 and GHRH Research

Growth hormone-releasing hormone, or GHRH, is an endogenous peptide involved in regulation of growth-hormone secretion.

CJC-1295 is a synthetic GHRH analogue developed to interact with the GHRH signalling system.

The DAC modification is designed to extend the peptide’s circulation time by enabling albumin binding. Research has therefore examined CJC-1295 as a tool for studying prolonged GHRH-related signalling.

This makes CJC-1295 with DAC particularly relevant to researchers studying:

GHRH Receptor Signalling

Researchers can investigate the interaction between a modified GHRH analogue and GHRH receptor pathways.

Long-Acting Peptide Design

The DAC modification provides an example of how albumin binding can be used in the design of longer-acting peptide molecules.

Pharmacokinetics

CJC-1295 has been investigated for its prolonged circulation and pharmacokinetic characteristics.

Peptide Structure-Function Relationships

Researchers can compare modified GHRH analogues and investigate how structural changes influence their biological characteristics.

CJC-1295 with DAC 5mg

The 5mg CJC-1295 with DAC option provides a defined quantity of the DAC-modified research peptide.

The 5mg presentation is suitable for laboratories that require a clearly labelled quantity of CJC-1295 with DAC for controlled research.

The exact purity, chemical form and analytical identity should always be confirmed using the COA for the specific batch supplied.

CJC-1295 with DAC Quality Testing

Quality documentation is particularly important for CJC-1295 because of the confusion between DAC and non-DAC products.

Researchers should look for:

• Explicit DAC identification
• Batch or lot number
• HPLC purity
• Mass-spectrometry identity confirmation
• Molecular-weight confirmation
• Net quantity
• Chemical formula
• Testing date
• Testing laboratory
• Certificate of Analysis

Current research-product documentation demonstrates the use of HPLC and mass spectrometry for CJC-1295 with DAC. One published 2026 batch record reported 98.70% HPLC purity for a particular 5mg batch.

That figure applies only to the referenced batch and should not be presented as the universal purity of CJC-1295 with DAC.

Certificate of Analysis for CJC-1295 with DAC

A Certificate of Analysis (COA) is especially useful for confirming that a product labelled CJC-1295 actually contains the DAC-modified material.

A suitable COA should ideally identify:

• Product name
• DAC status
• Batch number
• Quantity
• HPLC purity
• Mass-spectrometry result
• Molecular mass
• Testing laboratory
• Testing date

Researchers should match the lot number on the physical vial with the lot number shown on the COA.

CJC-1295 with DAC Molecular Identity

Current public chemical references identify the DAC conjugate as a distinct chemical structure.

The commonly reported DAC construct contains the modified GHRH sequence together with a C-terminal maleimidopropionyl-lysine DAC component. PubChem-based research references identify this construct separately as CID 91971820 and report a formula of C165H269N47O46 with a molecular weight of approximately 3,647.2 g/mol.

Because commercial naming has been inconsistent, the exact structure supplied should be confirmed against your own supplier’s documentation.

CJC-1295 with DAC Storage

CJC-1295 with DAC 5mg is commonly supplied as a lyophilised powder.

Published research-product specifications commonly recommend cold storage for the sealed lyophilised material, with some suppliers specifying approximately −20°C and protection from light and moisture.

Storage requirements can vary according to formulation and packaging, so the instructions supplied with the actual batch should always take precedence.
