CJC 1295 WITH DAC 2MG

PRODUCT DESCRIPTION

Growth hormone releasing hormone (GHRH) has been modified a number of times to produce analogues that preserve some of the hormone’s effects while eliminating others. One of those modifications, CJC-1295, consists of just the first 29 amino acids of GHRH. This analogue of GHRH, which is technically a maleimido derivative of hGRF(1-29), was created in an effort to produce a more soluble GH secretagogue that is easier to produce in large quantities but still preserves the physiologic actions of GHRH.

CJC-1295 Versus CJC-1295 DAC

CJC-1295 is a modified version of the first 29 amino acids of GHRH, which means it is chemically similar to other GHRH analogues, like Sermorelin. It is most similar to modified GRF (1-29), but the two peptides are not identical. A great deal of confusion arises because of the similarities between these peptides and because CJC-1295 was originally created with an added chemical compound called the drug affinity complex (DAC).

Originally, ConjuChem Biotechnologies, the developer of DAC, referred to the molecule containing DAC as simply CJC-1295. Confusion arose, however, because the peptide was also being offered without DAC. To avoid confusion, CJC-1295 that contains DAC is called CJC-1295-DAC and when it does not contain DAC it is referred to as CJC-1295 or CJC-1295-no DAC.

CJC-1295 and Growth Hormone Release

As a derivative of GHRH, it should come as no surprise that CJC-1295 promotes the release of GH. Studies show that a single dose of CJC-1295 increase GH levels in mice by 2-10 times. Peak GH levels are reached approximately 2 hours after administration and the effects last for about six days. Unlike other GH secretagogues, CJC-1295 preserves normal physiologic release of GH^[1]. That means that the normal circadian peaks and valleys seen in GH release remain intact and that CJC-1295 is a physiologic growth hormone releasing factor.
