Buy GHRP-2 at Loti Labs: Research Peptides for Science

Growth hormone releasing peptide 2 is a research tool for scientists studying endocrine pathways and cellular signaling mechanisms. This synthetic peptide has been popular in the lab due to its strong activity as a ghrelin receptor agonist and ability to stimulate gh release through well defined molecular pathways. When you buy ghrp 2 for research, you get a compound that has shown consistent results across various research applications, from growth hormone deficiency models to metabolic studies.

Understanding the molecular structure, mechanism of action and research applications of GHRP-2 allows scientists to design better experimental protocols and ensure proper handling and storage procedures to maintain peptide integrity throughout their studies.

Molecular Structure of GHRP-2

GHRP-2, a growth hormone secretagogue and non glycosylated polypeptide chain, has a defined molecular architecture that underlies its biological activity. The synthetic peptide has the amino acid sequence H-D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, with natural and modified amino acids that contribute to its stability and receptor binding properties.

Key Molecular Characteristics:

The D-amino acids at specific positions enhance the peptide’s resistance to enzymatic degradation and the C-terminal amide group (Lys-NH2) contributes to its biological activity. This structure is one of the most potent in the growth hormone releasing peptide family and is more stable than the natural hormone ghrelin.

Mechanism of Action

GHRP-2 binds to the growth hormone secretagogue receptor (GHS-R1α) primarily located in the pituitary gland and hypothalamus. Research shows this binding activates G-protein coupled signaling pathways that triggers calcium influx through voltage dependent channels and stimulates pulsatile growth hormone secretion from pituitary somatotrophs.

The peptide works through several interconnected cellular processes:

Primary Signaling Pathways:

• Ghrelin receptors activation leading to increased intracellular calcium
• Enhanced protein kinase C (PKC) pathway activity* Modulation of cAMP-dependent signaling in certain models
• Direct stimulation of gh releasing mechanisms independent of GHRH pathways

Studies in the lab show that GHRP-2 produces antinociceptive effects at the supraspinal level, suggesting additional receptor interactions beyond the primary growth hormone secretagogue receptor. The peptide is effective in stimulating gh release even in gh deficiency models where traditional GHRH pathways are impaired.

Research shows that somatostatin can modulate GHRP-2’s effects, indicating the peptide’s integration in existing hormonal regulation systems. This interaction makes the compound an investigational drug for understanding complex endocrine feedback mechanisms.

Research Studies and Applications

Scientific studies have investigated GHRP-2 across multiple research areas, providing valuable information on growth hormone physiology and metabolic regulation. These studies demonstrate the peptide’s use as a research tool for studying various biological processes.

Growth Hormone Deficiency Research

Studies in lit/lit mice, which have defective GHRH receptors, showed significant results for GHRP-2. 10 mcg of GHRP-2 produced gh release of 9.3 ± 1.5 ng/mL compared to 1.04 ± 1.15 ng/mL in control groups (p<0.001). This shows the peptide can bypass traditional GHRH-dependent pathways, making it useful for studying alternative growth hormone regulatory mechanisms.

Metabolic and Growth Performance Studies

Animal models have been used to study GHRP-2’s effects on metabolism and growth performance. Studies in swine showed peptide administration increased average daily gain by 22.35% and feed efficiency by 20.64%. These results provide insight into growth hormone signaling and metabolic efficiency, giving researchers tools to study muscle growth mechanisms and energy utilization pathways.

Appetite and Food Intake Research

As a ghrelin receptor agonist, GHRP-2 has been used to study appetite regulation mechanisms. Research showed the compound increased food intake by 35-36% compared to placebo controls in experimental models. These studies help scientists understand the complex relationship between the hormone ghrelin, growth hormone pathways and feeding behavior regulation.

Additional Research Applications

GHRP-2 has been studied in other research areas:

• Cardiovascular protection studies on myocardial signaling pathways* Immune system modulation research on anti-inflammatory properties
• Muscle growth and tissue development studies
• Insulin like growth factor pathway research

Storage and Handling Guidelines

Proper storage is critical to maintaining GHRP-2’s integrity and biological activity throughout research studies. The lyophilized growth hormone releasing peptide requires specific conditions to prevent degradation and ensure experimental reproducibility.

Storage Recommendations

Long Term Storage:

• Store lyophilized peptides desiccated below -18°C
• Keep temperature consistent to prevent freeze thaw cycles
• Allow vials to equilibrate to room temperature before opening
• Protect from light and moisture

Reconstituted Solutions:

• Stable for 3+ weeks at +4°C
• 3-4 months at -20°C
• Add carrier protein (0.1% HSA or BSA) for extended storage
• Use aqueous solutions or other aqueous solutions as per experimental design

Handling Protocols

Research shows proper handling techniques impact peptide stability and experimental outcomes. Scientists should avoid repeated freeze-thaw cycles which can denature the synthetic peptides and reduce biological activity. When preparing stock solutions, researchers should consider their experimental design and select appropriate solvents and concentrations.

The peptide is stable during standard shipping at room temperature, no special refrigeration required during transport. This makes it convenient for research labs to procure the product while maintaining product integrity.
