Mod GRF 1-29 & GHRP-2 Blend (10mg) – Premium Synergistic GH Research Peptide

Welcome to Liaocheng Yixin Company, your trusted source for premium mod grf 1-29 ghrp-2 10mg blend for research. As a specialized peptide synthesis manufacturer operating from our facility at No. 9 Lushan Road, Dongcheng Street, Liaocheng Economic and Technological Development Zone, Shandong Province, we provide high-quality research compounds for the global scientific community.

This 10mg blend combines Modified GRF 1-29 (a stabilized GHRH analog) with GHRP-2 (a potent growth hormone-releasing peptide) to create a research tool that activates complementary receptor pathways in the hypothalamic-pituitary axis . Our mod grf 1-29 ghrp-2 10mg blend for research offers investigators a convenient, pre-mixed formulation for growth hormone axis studies.

What is Mod GRF 1-29 & GHRP-2 Blend?

Modified GRF 1-29 (often referred to as CJC-1295 without DAC) is a tetrasubstituted GHRH analog with improved metabolic stability and resistance to enzymatic degradation . GHRP-2 (Pralmorelin) is a synthetic hexapeptide growth hormone secretagogue that acts on the ghrelin receptor (GHS-R1a) .

Key identifiers:

• Components: Modified GRF 1-29 (5mg) + GHRP-2 (5mg)

• Total Mass: 10mg lyophilized powder

• Modified GRF 1-29: Tetrasubstituted GHRH (1-29) analog

• GHRP-2: Hexapeptide (H-D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2)

Mechanism of Action in Research

The blend combines two distinct pathways to amplify growth hormone release :

Modified GRF 1-29 – GHRH Receptor Pathway

Modified GRF 1-29 binds the GHRH receptor (GHRHR) on anterior pituitary somatotrophs, activating Gs-coupled adenylyl cyclase signaling. This elevates intracellular cAMP, activates protein kinase A (PKA), and phosphorylates CREB to drive GH gene transcription and prime secretory vesicles for exocytosis. The amino acid substitutions at positions 2, 8, 15, and 27 confer resistance to DPP-IV cleavage, extending the effective half-life compared to native GHRH .

GHRP-2 – GHS-R1a Pathway

GHRP-2 activates the growth hormone secretagogue receptor type 1a (GHS-R1a), the endogenous ghrelin receptor, on pituitary somatotrophs. This triggers Gq-coupled phospholipase C (PLC) signaling, generating IP3 and DAG, mobilizing intracellular calcium, and activating protein kinase C (PKC). The resulting calcium influx directly triggers GH vesicle exocytosis .

Hypothalamic Effects of GHRP-2

GHRP-2 provides additional hypothalamic-level effects: it stimulates endogenous GHRH release from arcuate nucleus neurons and functionally suppresses somatostatin release from periventricular neurons. This dual hypothalamic action creates a permissive environment for maximal GH pulse amplitude. GHRP-2 may mildly stimulate ACTH, cortisol, and prolactin release—effects that researchers should consider in study design .

Synergistic Amplification

The combination of GHRH-pathway (cAMP/PKA) and ghrelin-pathway (PLC/PKC/Ca2+) activation produces synergistic GH release that exceeds the sum of individual peptide effects. This mirrors the physiological interplay between endogenous GHRH and ghrelin, where concurrent stimulation amplifies GH pulse amplitude significantly compared to either signal alone .

Scientific Research Applications

Growth Hormone Secretagogue Research

The Mod GRF 1-29 & GHRP-2 blend is used to study the interconnected pathways of GH regulation . Research demonstrates that GHRP-2 stimulates GH release through dual mechanisms: directly on the pituitary and via the arcuate nucleus of the hypothalamus . In growth hormone-deficient models, GHRP-2 has been shown to stimulate GH secretion and was well tolerated in research settings .

Metabolic and Body Composition Studies

Research suggests that GHRP-2 may increase lean body mass, reduce fat mass, increase exercise tolerance and maximum oxygen uptake, enhance muscle strength, and improve linear growth . Studies have documented GHRP-2’s effects on appetite, with experimental groups consuming approximately 35% more food compared to control groups .

Hormonal Profiling Research

GHRP-2 has been studied for its effects on growth hormone, cortisol, prolactin, and adrenocorticotropic hormone (ACTH) levels. In male research models, GHRP-2 stimulated increased levels of ACTH and cortisol hormones and a mild increase in prolactin levels, supporting the hypothesis that the peptide has profound hormonal secretion capabilities .

Cardiac and Immune Research

GHS-R1a has been identified in cardiac tissue, where GHRP-2 exerts direct cardioprotective effects independent of GH release . Both GH-releasing pathways have been linked to immune reconstitution and thymic regeneration, with growth hormone and ghrelin signaling promoting T-cell output and immune surveillance in aged models .
