Modified Growth Releasing Factor aminos 1-29, usually referred to as Modified GRF (1-29) or “ModGRF(1-29),” also known as CJC-1295 without DAC, is a synthetic analog of the endogenous peptide signalling hormone Growth Hormone Releasing Hormone (GHRH). Endogenously produced GHRH has 44 amino acids in its chain structure. A truncated synthetic form of GHRH called Sermorelin or GRF 1-29 has 29 amino acids; Modified GRF (1-29) is further changed in that it has four substituted aminos in its chain that serve the purposes of preventing degradation and oxidation in manufacture and transport as well as in vivo, while also increasing binding affinity to the GHRH receptors.
Modified GRF (1-29) is not CJC-1293 nor should it be referred to as such. Modified GRF (1-29) is identical to the portion of CJC-1295 DAC that is not bound to MPA, minus the lysine. The presence of lysine in a literal “CJC without DAC” in the absence of MPA would have the opposite effect of DAC: it would drastically reduce the active life of the peptide to that of Sermorelin. Modified GRF (1-29) is the same as CJC-1295 with out DAC.
According to a scientific study that has been based on animal test subjects, CJC-1295 No DAC’s functionality can be linked to an association it has with the peptide chain GHRH1-29. This particular peptide is a key component to a process linked to the negative feedback loop of an animal test subject’s growth hormone axis. This axis serves to regulate several endocrine system-related processes such as ones related to growth and metabolism. CJC-1295 No DAC serves to boost GHRH1-29’s rapid half-life by a significant amount, thus allowing its ability to regulate the processes it is charged with controlling to increase.
Because CJC-1295 No DAC has been shown to boost GHRH1-29’s half-life, scientific study based on animal test subjects has determined that the peptide’s presence can play a vital role in boosting specific functional processes, especially those that relate to protein synthesis. Some of the conceived benefits that the peptide has been linked to include a more efficient means of breaking down adipose tissue, an increase in muscular and skeletal tissue growth, an increase in bone density, and a boosted immune system. It has also been theorized that the peptide can be responsible for improving deep sleep since that is the period where most protein synthesis occurs.
CJC-1295 DAC vs. CJC-1295 No DAC
CJC-1295 DAC and CJC-1295 (also known as Modified GRF 1-29) are both Growth Hormone Releasing Hormones (GHRH). Their action in the human body is identical but the difference between the two peptides are the span of the half-life. Modified GRF 1-29 and Sermorelin have a very short-acting half-life of about 30 minutes, while CJC-1295 DAC has a half-life that can last up to approximately 8 days. Many a scientist have reported that the short half-life of Sermorelin and Modified GRF 1-29 is considered to be much more natural as they produce a short pulse of Human Growth Hormone.

Storage: Lyophilized peptides although stable at room temperature for 3 months, should be stored desiccated below -18°C. Upon reconstitution of the peptide, it should be stored at 4°C between 2-21 days and for future use below -18°C.
