What is CJC-1295 No DAC?
CJC-1295 No DAC is a synthetic research peptide also known as Modified GRF (1-29). It is an analog of the first 29 amino acids of growth hormone-releasing hormone (GHRH), a signaling peptide studied in laboratory models of endocrine signaling. The term “No DAC” distinguishes this material from DAC-conjugated versions of CJC-1295. Full Scale Peptides supplies CJC-1295 No DAC as a white lyophilized powder for laboratory research, with the batch Certificate of Analysis displayed on this page.
What does “No DAC” mean?
DAC stands for Drug Affinity Complex. In product naming, a DAC-conjugated form includes an additional affinity-complex component; CJC-1295 No DAC does not. “No DAC,” “CJC-1295 without DAC,” and “Modified GRF (1-29)” are commonly used names for this shorter research-peptide format. The distinction matters when reviewing literature, analytical documents, or laboratory inventory because the molecular form being referenced must be identified precisely.
