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.

This chemical is a synthetic analogue of the endogenous growth hormone releasing hormone (GHRH) which has approximately 44 amino acids in its chain structure.

Essentially, MOD-GRF 129 is a synthetically made version of GHRH[i] and is responsible for stimulating natural GH production in the body.

It works by stimulating secretion of GH from the pituitary gland. This means CJC 1295 no dac is more stable during storage and administration.

How MOD GRF 1 29 Works

Buy Mod GRF 5mg Online; Similarly to the body’s natural growth hormone releasing hormone, peptide mod grf works by binding to the growth hormone releasing hormone receptor in the pituitary gland.

From there, Mod-GRF 1-29 functions by amplifying the pulsatile release of GH. Thus, stimulating IGF-1 production. This peptide works most effectively when administered at the same time as GH release in the body.

Modified GRF’s effect on GH production[ii] is controlled by a negative feedback mechanism created by somatostatin. In turn, this has several plus sides. First, it prevents unhealthy levels of GH in the body. Secondly, it enables more natural patterns of GH concentrations in the body.

As a result, these two effects of MOD GRF 1-29 avoid negative side effects that can often accompany the use of artificial hGh.

In addition, CJC 1295 without DAC allows for the preservation of the hypothalamic-pituitary-somatotropic axis. This means it will not be possible to shutdown hormone production that often comes with synthetic hgh.

CJC 1295 no dac effects also include improving sleep and enhancing sleep waves, while reducing cortisol production otherwise known as the stress hormone.

Mod GRF 1 29 Benefits

Buy Mod GRF 5mg Online; There are many benefits of MOD GRF 1-29 peptide.

Due to its role in increasing GH production, MOD GRF 1-29 results include greater muscle and lean body mass as well as enhanced recovery from injuries. This is why many athletes and bodybuilders use this peptide – even though it’s not legal for human consumption.

According to scientists[iii], growth hormone is a vital component in numerous physiological processes. Too less and you could end up with a number of health complaints. However, as people get older, natural GH production decreases. That’s why recovery, energy levels, and overall wellness deteriorates as we age.

MOD GRF 1-29 supplementation may be able to help slow down that process and keep people young and healthy.
