CJC 1295 (without DAC)

CAS: 446036-97-1

CJC 1295 (without DAC) is a research peptide in the growth hormone / gh secretagogues category. Mod GRF 1-29 is a modified 29-amino acid fragment of GHRH with four amino acid substitutions that prevent enzymatic degradation: D-Ala2 prevents DPP-IV cleavage, Gln8 prevents asparagine rearrangement, Ala15 enhances bioactivity, and Leu27 prevents methionine oxidation. MiPeptidos offers CJC 1295 (without DAC) in 3 sizes with 99.7% verified purity and full analytical documentation.

How CJC 1295 (without DAC) Works

Mod GRF 1-29 is a modified 29-amino acid fragment of GHRH with four amino acid substitutions that prevent enzymatic degradation: D-Ala2 prevents DPP-IV cleavage, Gln8 prevents asparagine rearrangement, Ala15 enhances bioactivity, and Leu27 prevents methionine oxidation. Without the DAC moiety, it produces more physiologic pulsatile GH release patterns, stimulating somatotrophs through GHRH receptors with a much shorter duration of action.

Research Applications

1
Pulsatile GH release studies
2
Combination protocols with GHRPs (e.g., Ipamorelin)
3
Growth hormone axis assessment

Frequently Asked Questions

CJC 1295 (without DAC) (CAS: 446036-97-1) is a research compound, with a molecular weight of 3367.90 Da in the Growth Hormone / GH Secretagogues category. Mod GRF 1-29 is a modified 29-amino acid fragment of GHRH with four amino acid substitutions that prevent enzymatic degradation: D-Ala2 prevents DPP-IV cleavage, Gln8 prevents asparagine rearrangement, Ala15 enhances bioactivity, and Leu27 prevents methionine oxidation. Without the DAC moiety, it produces more physiologic pulsatile GH release patterns, stimulating somatotrophs through GHRH receptors with a much shorter duration of action. Researchers commonly investigate CJC 1295 (without DAC) for Pulsatile GH release studies, Combination protocols with GHRPs (e.g., Ipamorelin), Growth hormone axis assessment. Every vial from MiPeptidos includes batch-specific analytical documentation.
CJC 1295 (without DAC) is available in 3 sizes (2mg, 5mg, 10mg), so reconstitution volume depends on which vial you have. For the 2mg size, add 1mL of bacteriostatic water; for the 10mg size, use 2-3mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted CJC 1295 (without DAC) at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
CJC-1295 without DAC (also called Mod GRF 1-29) has a short half-life of ~30 minutes, producing sharp GH pulses that mimic the body natural pulsatile release pattern. The DAC version lasts 6-8 days and elevates GH baselines continuously. Many researchers prefer the non-DAC version for more physiological GH secretion patterns, and it pairs well with GHRPs like Ipamorelin. MiPeptidos offers a pre-mixed CJC+IPA combo vial alongside individual vials.
Store lyophilized CJC 1295 (without DAC) at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, CJC 1295 (without DAC) has a reported half-life of ~30 minutes, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every CJC 1295 (without DAC) order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-CJC1-2600315, tested February 27, 2026) shows 99.7% purity by HPLC, mass spectrometry confirmation at 3367.90 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
