CJC-1295 (No DAC): Complete Research Guide for Laboratory Use

CJC-1295 (No DAC) — also known as Modified GRF 1-29 — is a 29-amino-acid analog of growth hormone–releasing hormone (GHRH) lacking the Drug Affinity Complex. Without albumin binding, it retains a short, physiologically pulsatile profile in research models. It is widely used in somatotropic research to study acute GHRH receptor activation and pulsatile GH release patterns, often in combination with ghrelin-receptor agonists such as ipamorelin. For research teams sourcing CJC-1295 (No DAC), the most important variables are sequence fidelity, residual solvents, endotoxin load, and traceable batch documentation. Every vial of CJC-1295 (No DAC) supplied by Quality Peptide USA is American-synthesized, lot-controlled, and released only after independent HPLC-MS and LAL verification.

CJC-1295 (No DAC) is referenced across Pulsatile GH-axis research, GHRH receptor pharmacology, Secretagogue synergy studies (e.g., with ipamorelin) and adjacent investigative domains. As triple-receptor and dual-agonist research peptides expand the pharmacological toolbox, CJC-1295 (No DAC) continues to serve as a reference compound in comparative assays. Investigators routinely pair it with companion peptides from the Glow stack, Wolverine stack, or GHRH/GHRP secretagogue blends depending on study design.

Reconstitute CJC-1295 (No DAC) under sterile technique with bacteriostatic water (0.9% benzyl alcohol). Lyophilized vials remain stable refrigerated at 2–8°C; reconstituted aliquots should follow the storage window listed on the product page. Avoid freeze/thaw cycling, exposure to UV light, or contact with reactive metals. For prolonged storage, single-use aliquots in low-binding tubes at −20°C preserve sequence integrity.

Every batch of CJC-1295 (No DAC) passes RP-HPLC (≥ 99% purity threshold), ESI mass spectrometry confirmation, Karl Fischer water content, and a Limulus Amebocyte Lysate endotoxin screen below 0.10 EU/mg. Certificates of analysis are published with every order — no email request required.

American-synthesized research peptides eliminate the customs delays, opaque batch chains, and inconsistent cold-chain handling associated with overseas suppliers. Quality Peptide USA synthesizes, lyophilizes, and ships CJC-1295 (No DAC) from domestic facilities, with cold-pack dispatch on every order placed before the 2 PM EST cut-off.
