CJC-1295 with DAC: The Long-Acting GHRH Analog for Advanced Endocrine Research
eupeptidelap.co.uk is proud to present CJC-1295 with DAC 5mg, a premium research-grade growth hormone-releasing hormone (GHRH) analog manufactured to the highest analytical standards. As a trusted peptide vendor uk and leading EU peptide supplier, we provide researchers across Europe with CJC-1295 DAC for sale that delivers exceptional purity, consistency, and documented quality for advanced studies in endocrinology, metabolism, and cellular growth .
CJC-1295 with DAC (Drug Affinity Complex) is a synthetic peptide analog of growth hormone-releasing hormone (GHRH) consisting of 29 amino acids with a molecular weight of approximately 3647 Da . What distinguishes this peptide from other GHRH analogs is the presence of the Drug Affinity Complex (DAC) moiety—a lysine derivative that enables the peptide to bind covalently to serum albumin, the most abundant protein in plasma . This binding dramatically extends the peptide’s half-life from minutes to approximately 6-8 days in humans, providing sustained stimulation of the anterior pituitary gland .
The peptide incorporates strategic amino acid substitutions that enhance its stability and biological activity: D-alanine at position 2 prevents DPP-IV enzyme cleavage, glutamine at position 8 reduces asparagine rearrangement, alanine at position 15 increases biological action, and leucine at position 27 prevents methionine oxidation . These modifications, combined with the DAC technology, create a remarkably stable peptide that resists rapid degradation and maintains prolonged bioavailability .
CJC-1295 with DAC works by binding to GHRH receptors on somatotroph cells in the anterior pituitary gland, stimulating the secretion of growth hormone (GH) in a sustained manner . The elevated GH levels subsequently increase production of insulin-like growth factor 1 (IGF-1), the primary mediator of GH’s anabolic effects . Clinical studies have demonstrated that a single injection of CJC-1295 can increase plasma GH levels by 2- to 10-fold for 6 days or longer, and plasma IGF-1 levels by 0.5- to 3-fold for 9 to 11 days .
For researchers seeking to buy peptide online EU for investigations into growth hormone dynamics, metabolic regulation, cellular aging, or tissue regeneration, eupeptidelap.co.uk offers this premium research compound with comprehensive documentation, including Certificates of Analysis and batch-specific purity data.

The Scientific Foundation of CJC-1295 with DAC Research
Molecular Architecture and Design
CJC-1295 with DAC represents a sophisticated advancement in GHRH analog design. The peptide is based on the biologically active 1-29 fragment of endogenous GHRH but incorporates key modifications that fundamentally alter its pharmacokinetic profile .
Drug Affinity Complex (DAC) Technology: The defining feature of this peptide is the DAC moiety—a lysine derivative linked to a reactive chemical called maleimidoproprionic acid (MPA) that enables covalent binding to circulating albumin after subcutaneous injection . This albumin-binding property protects the peptide from rapid enzymatic degradation and renal clearance, allowing it to circulate in the bloodstream for extended periods .
Structural Modifications: Beyond the DAC technology, CJC-1295 incorporates four strategic amino acid substitutions that enhance its stability and biological activity :
-
D-alanine at position 2: Prevents cleavage by dipeptidyl peptidase IV (DPP-IV), the primary enzyme responsible for degrading endogenous GHRH
-
Glutamine at position 8: Reduces asparagine rearrangement and amide hydrolysis
-
Alanine at position 15: Increases biological potency and receptor binding affinity
-
Leucine at position 27: Prevents methionine oxidation, preserving structural integrity
These combined modifications create a peptide with dramatically improved pharmacokinetics—extending the half-life from approximately 30 minutes for unmodified GHRH to an estimated 6-8 days for CJC-1295 with DAC .
Mechanism of Action
CJC-1295 with DAC functions as a potent GHRH receptor agonist, binding to receptors on somatotroph cells in the anterior pituitary gland . This binding initiates intracellular signaling cascades that stimulate the synthesis and release of growth hormone.
The prolonged presence of the peptide in the bloodstream, facilitated by albumin binding, provides sustained stimulation of the pituitary gland, leading to elevated GH levels over extended periods . The increased GH secretion subsequently stimulates hepatic and peripheral production of insulin-like growth factor 1 (IGF-1), which mediates many of GH’s anabolic effects .
Pharmacokinetic Profile
The pharmacokinetic properties of CJC-1295 with DAC are remarkable compared to other GHRH analogs:
| Parameter | CJC-1295 with DAC | Unmodified GHRH / No DAC Versions |
|---|---|---|
| Half-Life | ~6-8 days in humans | ~30 minutes |
| GH Elevation | 2- to 10-fold for 6+ days | Brief, pulsatile |
| IGF-1 Elevation | 0.5- to 3-fold for 9-11 days | Transient |
| Dosing Frequency | Once weekly or less | Multiple times daily |
| Mechanism | Albumin binding via DAC | No albumin binding |
