Structural & Stability Notes
CJC-1295 (No DAC) is a modified 29-amino-acid peptide derived from growth hormone–releasing factor (GRF 1–29). Targeted amino acid substitutions enhance resistance to enzymatic degradation while preserving the core structural framework. Unlike DAC-conjugated versions, this variant does not include a drug affinity complex moiety, resulting in a shorter structural persistence profile under research conditions. Lyophilized presentation supports stability during storage, and protection from moisture, light, and repeated freeze–thaw cycles helps maintain peptide integrity for laboratory and analytical applications.
