CJC-1295 without DAC (also known as Modified GRF 1-29) is a 29-amino-acid peptide that acts as a selective agonist at the growth hormone-releasing hormone receptor. Unlike CJC-1295 with DAC (Drug Affinity Complex), which binds to plasma albumin to extend its half-life to several days, CJC-1295 without DAC exhibits a rapid clearance half-life of approximately 30 minutes.
This abbreviated half-life allows researchers to closely mimic endogenous nocturnal GH secretion pulses without causing sustained basal GH elevation. Studies evaluating growth hormone secretagogues often pair CJC-1295 without DAC with selective GHRPs like ipamorelin to examine synergistic anterior pituitary stimulation.
PX1 Research provides laboratory-grade cjc-1295 without dac research peptide verified at ≥99% purity via High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS). Every lot includes a public, verifiable test report detailing peptide content, identity, and endotoxin burdens under 0.01 EU/mg.
The cjc-1295 without dac peptide is a modified form of natural GHRH (1-29), substituting four amino acids at positions 2, 8, 15, and 27. These biochemical modifications preserve binding affinity for the GHRH receptor while offering increased resistance to enzymatic cleavage by dipeptidyl peptidase IV (DPP-IV) compared to native GHRH (1-29) or sermorelin.
When introduced into isolated somatotroph cultures or animal models, CJC-1295 without DAC binds directly to the growth hormone-releasing hormone receptor (GHRHR). This activates the adenylate cyclase-CAMP-protein kinase A pathway, stimulating the transcription and exocytosis of growth hormone storage vesicles. Preclinical models indicate that this mechanism enhances serum GH and downstream insulin-like growth factor 1 (IGF-1) concentrations without inducing irreversible receptor desensitization.
Because it lacks the lysyl-linker and Drug Affinity Complex moiety, CJC-1295 without DAC does not form covalent bonds with serum albumin. Consequently, serum concentration peaks rapidly post-administration and degrades predictably, allowing investigators to control the precise duration of GHRH receptor activation during time-course bioassays. Researchers interested in broader secretagogue mechanisms can explore our complete catalog of research peptides for comparative study designs.
Understanding the biochemical distinctions between CJC-1295 without DAC and CJC-1295 DAC is crucial when designing cell culture or animal research protocols. The primary structural difference lies in the inclusion of the Drug Affinity Complex (DAC), a maleimidopropionic acid group attached to the C-terminus of the 29-amino-acid sequence.
In assays containing serum, CJC-1295 DAC covalently binds to circulating albumin molecules. This modification shields the peptide backbone from renal clearance and enzymatic breakdown, extending its biological half-life from approximately 30 minutes to between 6 and 8 days. While this sustained presence yields continuous baseline GH and IGF-1 elevation, it eliminates the natural physiological pulsatility of pituitary secretion.
In contrast, CJC-1295 without DAC clears rapidly, making it the primary model for investigations requiring acute GH spikes followed by full baseline recovery. Researchers exploring dynamic endocrine signaling pathways often favor the non-DAC variant to avoid baseline IGF-1 accumulation and pituitary desensitization.

A substantial portion of literature surrounding secretagogue research focuses on the co-administration of cjc 1295 without dac and ipamorelin. Combining a GHRH analog with a Ghrelin Receptor (GHS-R1a) agonist yields a powerful synergistic effect on pituitary GH release that exceeds the additive arithmetic sum of either peptide tested independently.
CJC-1295 without DAC stimulates the activation of GHRH receptors, initiating intracellular cAMP synthesis. Simultaneously, ipamorelin research peptide acts selectively on the growth hormone secretagogue receptor, initiating a parallel intracellular pathway mediated by phospholipase C and intracellular calcium release. Furthermore, GHS-R1a agonism suppresses somatostatin activity, removing the central nervous system brake on anterior pituitary somatotrophs.
In preclinical trials, co-administering these two agents results in a amplified GH pulse without significant off-target elevations in cortisol, prolactin, or aldosterone. Laboratories designing comparative secretagogue protocols can source both ipamorelin and cjc-1295 without dac research peptide directly from PX1 Research with matching lot purity assurances.
Assuring scientific reproducibility requires inspecting a comprehensive cjc 1295 no dac test report prior to initiating reconstitution or assay work. Low-quality or unverified peptides introduce chemical contaminants, misfolded sequences, and toxic bacterial endotoxins that invalidate cellular assays and harm animal models.
A valid Certificate of Analysis (COA) must provide three essential analytical metrics: High-Performance Liquid Chromatography (HPLC) chromatograms confirming analytical purity (ideally ≥99.0%), Liquid Chromatography-Mass Spectrometry (LC-MS) confirming exact molecular mass matching the theoretical weight of 3367.9 Da, and quantitative chromogenic Limulus Amebocyte Lysate (LAL) assay results indicating endotoxin levels below 0.01 EU/mg.
PX1 Research enforces strict lot traceability for every batch. Every product page contains downloadable, lot-specific COAs generated by independent, ISO/IEC 17025 accredited third-party analytical laboratories in the United States. Inspect our verified cjc-1295 no dac test report documentation directly before placing your order.
A common point of inquiry among procurement managers is whether cjc-1295 dac legal status or CJC-1295 without DAC compliance restricts laboratory purchase within the United States. Under current federal regulations, neither CJC-1295 without DAC nor CJC-1295 DAC are listed as Controlled Substances under the Controlled Substances Act (CSA).
It is entirely legal for university laboratories, research institutions, and corporate R&D entities to purchase, possess, and analyze CJC-1295 without DAC strictly for *in vitro*, analytical, and preclinical research applications. Legal compliance hinges on the intended use: these products are explicitly non-clinical research chemicals and are not approved by the FDA for human consumption, medical diagnosis, or therapeutic use.
PX1 Research complies with all US chemical distribution regulations by shipping exclusively to research entities and qualified personnel. Institutional buyers requiring bulk quantities or official institutional invoicing can request custom terms through our bulk peptide wholesale portal.
To ensure internal validity across experimental trials, research teams must evaluate vendors using objective, verifiable quality benchmarks rather than promotional marketing claims. The criteria below illustrate the standards applied at PX1 Research compared to standard industry practices:
1. Purity Verification: Every PX1 lot undergoes mandatory RP-HPLC analysis ensuring ≥99.0% purity. Standard suppliers frequently sell batches between 90-95% purity containing significant synthesis truncated sequences.
2. Molecular Mass Confirmation: PX1 provides LC-MS spectra verifying exact sequence identity against theoretical monoisotopic mass. Generic suppliers often lack mass-spec identification entirely.
3. Endotoxin Quantification: PX1 tests every single lot using chromogenic LAL testing to guarantee <0.01 EU/mg, preventing lipopolysaccharide-induced inflammatory artifacts in cell lines. Conventional vendors rarely provide endotoxin metrics.
4. Sourcing and Synthesis: PX1 peptides are synthesized using solid-phase peptide synthesis (SPPS) in US-based, state-of-the-art facilities. Importers obscure overseas origins and re-pack raw unpurified powders.
5. Cold-Chain and Shipping Speed: PX1 dispatches all orders same-day (M-F before 2 PM PST) from facilities in California and Arizona using temperature-stable packaging. Generic vendors rely on slow drop-shipping network delays.

The online peptide market contains numerous vendors that fail basic scientific quality control standards. Identifying these red flags prevents research budget waste and avoids corrupted experimental datasets:
Red Flag 1: Missing or Generic COAs. Avoid vendors that display single COA image templates without batch-specific lot numbers, test dates, or third-party laboratory seals. Every lot must have its own unique, traceable test document.
Red Flag 2: Clinical or Human Dosing Claims. Legitimate scientific reagent suppliers never supply human administration protocols, medical advice, or dosage calculators. Direct mentions of human use signal a non-compliant consumer operation unfit for laboratory supply.
Red Flag 3: Lack of Mass-Spec Data. HPLC purity alone is insufficient; it measures sample homogeneity, not molecular identity. A vendor unable to provide LC-MS cannot prove the vial contains CJC-1295 rather than an unlinked fragment or sequence variant.
Red Flag 4: Unexplained Price Discrepancies. Synthesizing, purifying, and testing peptide sequences to ≥99% purity incurs significant manufacturing costs. Suspiciously low prices almost always indicate unpurified raw materials, heavy metal contamination, or high endotoxin levels.
CJC-1295 without DAC is delivered as a lyophilized (freeze-dried) sterile white powder in sealed glass vials. To preserve secondary structure and prevent rapid enzymatic or hydrolytic degradation, strict handling procedures must be followed in the laboratory.
Upon arrival, lyophilized vials should be stored in a controlled freezer environment at -20°C (or -80°C for long-term storage exceeding 12 months), protected from direct light exposure. Avoid unnecessary freeze-thaw cycles, which can cause peptide bond cleavage and aggregation.
Reconstitution should be performed under a laminar flow hood using sterile bacteriostatic water (0.9% benzyl alcohol) or sterile deionized water, depending on assay tolerance. Direct the solvent stream down the inner glass wall of the vial rather than shooting directly onto the peptide cake. Gently swirl the vial until dissolved—never shake vigorously, as mechanical agitation can denature fragile peptide chains. Once reconstituted, store solution aliquots at 2°C to 8°C and use within 21 to 28 days.
