CJC – 1295 DAC (5 MG)

Description

CJC-1295 Versus CJC-1295 DAC

CJC-1295 is an altered version of the first 29 amino acids of GHRH, which means it is chemically like other GHRH analogues, like Sermorelin. It is most like modified GRF (1-29), but the two peptides are not identical. A great deal of confusion arises due to the similarities between these peptides and with the origin of CJC-1295 as an added chemical compound known as the drug affinity complex abbreviated as DAC. DAC is added to the molecule, with the help of a lysine linker, to safeguard the peptide while it circulates in the blood stream. By allowing peptides to bind to the common blood protein albumin, DAC helps to ensure that the half-life of CJC-1295 is much longer than similar molecules like GRF (1-29).

Originally, ConjuChem Biotechnologies, the developer of DAC, referred to the molecule containing DAC as simply CJC-1295. Confusion arose, nonetheless, 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 Research

CJC-1295 and Growth Hormone Release. As a derivative of GHRH, it should come as no brainer that CJC-1295 aggravates the release of growth hormone. 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 nearly 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. Preserving physiologic release of GH even while influencing the maximum concentration of the hormone in the bloodstream is critical to ensuring enhanced effects without increased side effects. Specifically, CJC-1295 has been shown to preserve the physiologic effects of growth hormone’s on hyperplasia, hypertrophy, bone density, blood sugar, fat metabolism, protein synthesis, and myocardial (heart cell) function.

CJC-1295 and Growth

Studies in mice without normal GHRH physiology have shown that CJC-1295 preserves normal GH release[2]. This makes the peptide potentially useful as a therapy for abnormal growth in a variety of mammalian species, humans included. Preserving normal pulsatile release of GH is critical to ensuring that proper release of downstream hormones, such as insulin-life growth factor-2 (IGF-1).

CJC-1295 and Infertility

Research from the early 1990s suggests that CJC-1295 and other GRF analogues may be useful in promoting ovulation in infertile female patients. Scientists have long known that ovulation is dependent on IGF-1 and that it is also likely influenced by GH release and cycling. Research in animal models of superovulation has helped to confirm these theories by showing that both GH and IGF-1 levels rise significantly surrounding the time of ovulation. Further, these studies indicate that exogenous administration of GH secretagogues, like CJC-1295, is enough to cause appropriate ovulation[3]. There is some speculation that CJC-1295 and other analogues may even be useful in male infertility by helping to regulate sperm production. This latter hypothesis has yet to be tested.
