Mod GRF (1-29) & GHRP-6 Peptide Blend

Mod GRF (1-29) & GHRP-6 are considered to be synergistic peptides. These peptides appear to increase the release of growth hormone (GH). The full structure of Growth Hormone Releasing Hormone (GHRH) contains 44 amino acids. Researchers have noticed that the first 29 amino acids (1-29) appear to contain the full biological activity of GHRH. This fraction is called Growth Hormone Releasing Factor (GRF 1-29).[1] GRF 1-29 appears to be biologically more active and has a longer duration of action as it evades metabolic clearance. Similarly, Growth Hormone Releasing Peptide-6 (GHRP-6) is under study as a stimulator of growth hormone release from the anterior pituitary gland.[2] According to the researchers: “These results provide evidence that the GH-stimulatory effects of GHRP-6 are achieved through activation of the PI second messenger system and thus support earlier findings that PKC and Ca2+ play central roles in mediating the effects of GHRP-6.”
A blend of Mod GRF (1-29) & GHRP-6 may lead to superior growth hormone release.

Mod GRF (1-29) & GHRP-6 Research

Mod GRF (1-29) & GHRP-6 Peptides and Brain Function
Researchers have suggested that Mod GRF (1-29) and GHRP-6 exhibit potential within the context of neurodegenerative conditions. Studies in rodents reported that exposure to GHRP-6 appeared to help improve and solidify memory recall and learning behaviors, when compared to the rates of recall and learning in control groups. Research also suggests that growth hormone analogs, such as GHRP-6, may possibly assist spatial learning.[3] GHRP-6 has been associated with research in acute stroke, as it may provide improved aspects of brain function, such as spatial learning and problem-solving. Research suggests that GHRP-6 and other ghrelin analogs may induce greater blood supply to the brain, possibly inhibiting the development of new strokes and improve recovery following established strokes by reducing infarct size and promoting new tissue development. Mod GRF (1-29) & GHRP-6 blend may reduce apoptosis in brain cells, lower inflammation, and prevent structural and functional decline within the brain. Research is ongoing.

Mod GRF (1-29) & GHRP-6 Peptides and Cell Aging
The levels of growth hormone peak and then decline, and declining levels of growth hormone have been suggested by researchers to have an impact on cell-longevity and function. The synergy of Mod GRF (1-29) and GHRP-6 appear to naturally increase growth hormone levels and thereby might inhibit cell aging processes. This mitigation is considered a potential, due to the proposed ability of these peptides to boost cellular repair, reduce cellular damage due to oxidative stress, and reduce telomere shortening.

Mod GRF (1-29) & GHRP-6 Peptides and Tissue Repair
Mod GRF (1-29) & GHRP-6 in combination appears to increase tissue synthesis. GHRP-6 has been suggested by researchers to interact with CD36 receptors associated with angiogenesis, the growth of new blood vessels.[4] The researchers report that “In covalent competition binding studies with the GHRP-6 prototype hexarelin bearing a radiotracer, certain [aza-Glu]GHRP-6 azapeptides retained relatively high (2-27 μM) affinity for the CD36 scavenger receptor.” The growth of new blood vessels supports the development of new tissue and hastens repair to damages tissues. Animal study findings have suggested that GHRP-6 may thus impact tissue repair processes, increasing the synthesis of extracellular proteins like collagen, stimulating scar formation.

Mod GRF (1-29) & GHRP-6 Peptides and Heart Disease
Oxidative stress is considered to result in increased Reactive Oxygen Species (ROS) that may result in cardial damage. Research suggests that growth hormone analogs such as Mod GRF (1-29) and GHRP-6 may reduce the levels of oxidative stress and protect vulnerable but viable cells. These peptides may also improve cardiovascular function by building a stronger lipid profile, including increased triglyceride breakdown.

Mod GRF (1-29) & GHRP-6 Peptides and Muscle Cell Growth
Muscle growth is one of the most studied effects of growth hormones. Growth hormone analogs such as Mod GRF (1-29) & GHRP-6 have been studied for their potential to increase muscle mass via two different mechanisms: muscle hypertrophy and hyperplasia. Muscle hypertrophy results in increased muscle mass due to the increased size of already present muscle fibers. Muscle hyperplasia increases muscle mass by increasing the number of muscle fibers.

Mod GRF (1-29) & GHRP-6 Peptides and Bone Development
Growth hormone analogs appear to mediate action on bone mass via Insulin-Like Growth Factor 1 (IGF-1).[5] IGF-1 is suggested by researchers to promote the growth, differentiation, and survival of bone-forming cells. IGF-1 appears to improve the mineralization of bones and increases bone mineral density. In addition, it may also prevent the excessive hormone-induced loss of bones. This way, GH/IGF-1 interplay may improve bone quality and reduce the risk of conditions such as osteoporosis.
