What Is CJC-1295? GHRH Analog Explained (With and Without DAC)
CJC-1295 is a synthetic growth hormone releasing hormone (GHRH) analog. Here is the difference between the DAC and no-DAC versions and what to check on a COA.
CJC-1295 is a synthetic analog of growth hormone releasing hormone (GHRH). It is sold for laboratory research use only, commonly in two forms: with DAC and without DAC.
Research-use status
CJC-1295 is a modified GHRH analog. Published literature on it is mostly animal and early clinical work, and this page does not summarise effects or uses. Vendors frequently sell it alongside, or pre-mixed with, Ipamorelin, a ghrelin-receptor agonist from a different pharmacological class.
CJC-1295 with DAC versus without DAC
DAC stands for Drug Affinity Complex, a modification that greatly extends the peptide's half-life so it circulates far longer. The no-DAC version (sometimes labeled Mod GRF 1-29) is shorter-acting. These behave very differently, so confirm which version a vendor is selling before comparing.
What to check on a CJC-1295 COA
Confirm the named lab, identity by mass spectrometry, HPLC purity with decimals, and whether the product is the DAC or no-DAC form. For injectable research preparations, endotoxin testing adds assurance.
Frequently Asked Questions
What is the difference between CJC-1295 with and without DAC?
DAC (Drug Affinity Complex) extends the half-life so the peptide lasts much longer in circulation. The no-DAC form is shorter-acting and is sometimes labeled Mod GRF 1-29.
Is CJC-1295 the same as Ipamorelin?
No. CJC-1295 is a GHRH analog; Ipamorelin is a growth hormone secretagogue. They belong to different pharmacological classes and vendors often sell them together.
What should a CJC-1295 COA show?
A named lab, mass-spec identity, HPLC purity with decimals, the DAC or no-DAC designation, and ideally endotoxin testing.
