What is CJC-1295 (No DAC)? Molecular structure and mechanism

CJC-1295 (No DAC), structurally recognized as Modified GRF (1-29), is a 29-amino-acid synthetic peptide derivative of growth hormone-releasing hormone (GHRH). It is specifically modified at positions 2, 8, 15, and 27 to incorporate D-alanine, glutamine, alanine, and leucine, respectively. These precise structural modifications enhance enzymatic resistance against dipeptidyl peptidase IV (DPP-IV) degradation, significantly extending plasma stability relative to native GHRH (1-29).

In preclinical research settings, CJC-1295 functions as a GHRH receptor agonist. Upon binding to GHRH receptors on pituitary somatotropes, it stimulates adenylate cyclase activity, raising intracellular cyclic AMP (cAMP) levels and triggering exocytosis of endogenous growth hormone. Studied as a long-acting growth-hormone-releasing hormone that sustains GH and downstream IGF-1 levels for tissue repair research, this molecule offers researchers a reliable mechanism to evaluate cell proliferation, collagen deposition, and protein translation.

Unlike native GHRH, which is rapidly cleaved in vivo within minutes, cjc no dac provides extended metabolic resistance while retaining a physiological pulse-like clearance profile. This distinct kinetic footprint prevents continuous receptor overstimulation and receptor desensitization in long-term cellular studies.

CJC-1295 (No DAC) vs. CJC-1295 with DAC: Structural differences

The primary distinction between CJC-1295 (No DAC) and CJC-1295 DAC lies in the presence of the Drug Affinity Complex—a lysine linker attached to a maleimido-propionic acid group. The DAC moiety allows covalent bonding to circulating serum albumin upon administration, extending the biological half-life from approximately 30 minutes to over 6–8 days.

For research applications requiring acute, physiological GH pulses that mimic biological circadian rhythms, CJC-1295 (No DAC) is preferred. The lack of a permanent albumin-binding affinity allows quick clearance between experimental time points, enabling researchers to tightly control the window of pituitary stimulation.

Conversely, researchers examining steady-state baseline growth hormone elevations over prolonged periods without multiple daily exposures may choose to study CJC-1295 DAC. However, for studies prioritizing peak-to-trough dynamics or combinatorial trials with GHRPs, the No DAC version remains the standard laboratory control.

Evaluating synergy: CJC-1295 (No DAC) and Ipamorelin co-administration

In preclinical literature, combining GHRH analogs with selective growth hormone secretagogue receptor (GHSR-1a) agonists demonstrates pronounced synergistic effects on growth hormone release. While GHRH derivatives like CJC-1295 (No DAC) activate the cAMP-dependent pathway, ghrelin mimetics act via the phospholipase C (PLC) pathway.

When evaluated simultaneously in model systems, the dual receptor activation produces a multiplicative—rather than additive—release of pituitary growth hormone. Researchers investigating complex metabolic pathways or tissue remodeling often evaluate cjc ipamorelin combined formulations to observe optimal somatotrope response without triggering significant secondary cortisol or prolactin release.

PX1 Research provides both individual compounds—including high-purity Ipamorelin vials—as well as pre-formulated research blends, fully documented with lot-specific chromatographic verification for both active pharmaceutical ingredients.

Quality standards: Analytical testing and endotoxin verification

Peptide purity directly influences experimental reproducibility. Low-purity preparations containing truncated peptide fragments, residual TFA (trifluoroacetic acid), or synthesis byproducts can interfere with receptor binding kinetics and yield false toxicological reads in cell culture.

At PX1 Research, every batch of CJC-1295 (No DAC) undergoes rigorous third-party analytical evaluation prior to listing. High-Performance Liquid Chromatography (HPLC) confirms purity levels equal to or exceeding 98.0%, while Mass Spectrometry (MS) confirms exact molecular weight (3,367.9 Da).

Crucially, PX1 conducts quantitative Chromogenic LAL Endotoxin Testing on every lot to guarantee endotoxin content remains below 0.1 EU/mg. Excessive bacterial endotoxins introduce pyrogenic background noise in cellular assays; our strict limits prevent inflammatory artifacts from compromising your research data. Analytical COAs are published directly on our site and linked to every physical shipment.

Red flags when sourcing CJC-1295 (No DAC) online

The online peptide market presents significant variance in chemical quality and vendor transparency. To protect research budget integrity and experimental validity, investigators should screen potential suppliers against common industry red flags:

1. Missing Lot-Specific COAs: Generic, un-dated, or blurred analytical certificates often indicate recycled documentation across multiple un-tested factory batches.

2. Absence of Endotoxin Testing: HPLC alone shows chemical purity but does not detect bacterial endotoxin contamination, which alters cell signaling and viability.

3. Oversized Vials with Unspecified Fillers: Vendors using low-grade mannitol or bulk bulking agents without chemical documentation introduce unknown variables into solution chemistry.

4. Ambiguous Vendor Sourcing: Suppliers operating through non-traceable drop-ship networks lack direct oversight of storage climate, analytical integrity, and transit conditions.

PX1 Research eliminates these risks through 100% domestic processing, traceable lot tracking, and transparent analytical documentation accessible prior to payment.

Vendor comparison matrix: PX1 Research vs. industry suppliers

Selecting a research chemical supplier requires evaluating operational standards against verifiable benchmarks. The following grid outlines how PX1 Research measures against typical marketplace vendors:

• Synthesis Origin: PX1 Research utilizes domestic, state-of-the-art USA facilities. Standard suppliers routinely source unverified imports from offshore traders.

• Analytical Transparency: PX1 publishes individual lot-specific HPLC, MS, and quantitative endotoxin data. Standard suppliers frequently show generic analytical sheets or rely solely on manufacturer claim sheets.

• Purity Threshold: PX1 enforces a mandatory ≥98.0% purity floor for all research peptides. Standard suppliers often list broad 95% ranges with unquantified impurities.

• Shipping Operations: PX1 guarantees same-day fulfillment before 3:00 PM EST from California and Arizona distribution hubs using climate-monitored packaging. Standard suppliers often experience multi-day fulfillment delays and untracked overseas handling.

• Customer & Technical Support: PX1 provides dedicated USA-based laboratory customer support with rapid response times. Standard suppliers frequently operate through automated or non-responsive contact forms.

Laboratory preparation: Reconstitution and storage guidelines

CJC-1295 (No DAC) is supplied as a lyophilized (freeze-dried) powder requiring proper laboratory reconstitution prior to experimental use. Reconstitution should occur in a sterile laminar flow hood using bacteriostatic water (0.9% benzyl alcohol) or sterile laboratory grade water, depending on the research protocol.

To reconstitute, direct the diluent down the glass vial wall rather than directly onto the lyophilized cake. Gently swirl the vial until the peptide completely dissolves; avoid vigorous shaking, which can cause mechanical agitation and polypeptide denaturation.

Prior to reconstitution, dry lyophilized powder should be stored at -20°C for long-term stability (up to 24 months). Once reconstituted, liquid solutions must be kept refrigerated at 2°C to 8°C and evaluated within 28 days to prevent hydrolysis or chemical degradation. For detailed stability data, researchers can consult our comprehensive peptide research library.
