Mod GRF, Hexarelin 10mg (Blend)

Mod GRF & Hexarelin Blend is a dual-component growth hormone secretagogue formulation supplied at ≥98% purity, designed exclusively for advanced in vitro and preclinical research applications. This lyophilized blend integrates a stabilized GHRH analog with one of the most potent synthetic GHS-R1a agonists available, providing a powerful biochemical platform for investigating synchronized somatotropic signaling. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

Available exclusively through The Peptide Store, the Mod GRF & Hexarelin Blend is engineered as a high-resolution research tool for laboratories studying growth hormone exocytosis, receptor-ligand kinetics, and dual-pathway regulation within the somatotropic axis. By combining two mechanistically distinct secretagogues into a single uniform lyophilized matrix, this formulation eliminates compounding weighing variables and delivers a reproducible, synergistic platform for multi-receptor research models. Its integrated presentation makes it a preferred choice for investigators seeking to buy research peptide blends that maximize experimental efficiency and biochemical consistency.

Peptide Structure & Amino Acid Sequence

This blend comprises two structurally distinct peptide components. Modified GRF (1-29), also referred to as Mod GRF, is a tetrasubstituted analog of the endogenous GHRH(1-29) fragment. Its four strategic amino acid substitutions — at positions 2, 8, 15, and 27 — confer significantly enhanced enzymatic stability and extended receptor occupancy compared to the native sequence. Hexarelin (His-D-2-MeTrp-Ala-Trp-D-Phe-Lys-NH₂) is a synthetic hexapeptide and potent agonist of the growth hormone secretagogue receptor subtype 1a (GHS-R1a), operating through a ghrelin-mimetic mechanism entirely distinct from GHRH signaling. Together, these two peptides engage complementary receptor populations on somatotroph cells, enabling researchers to model synchronized pituitary degranulation with exceptional biochemical resolution.

Purity & Analytical Verification (HPLC & MS)

Every batch of the Mod GRF & Hexarelin Blend supplied by The Peptide Store undergoes rigorous analytical verification prior to release. High-Performance Liquid Chromatography (HPLC) confirms ≥98% purity for both individual components within the blend matrix. Mass Spectrometry (MS) validates the molecular integrity and correct amino acid composition of each peptide, ensuring that no truncated sequences, oxidized residues, or extraneous impurities compromise the research-grade standard. Certificates of Analysis are available upon request, supporting full traceability and experimental reproducibility.

Quality Control & Lyophilization Integrity

The lyophilization process employed for this blend is optimized to preserve the conformational stability and biochemical activity of both peptide components simultaneously. Freeze-drying under controlled conditions removes residual moisture to levels that prevent degradation during storage and transit. Each vial is sealed under inert conditions to protect against oxidation and microbial contamination. The resulting lyophilized cake exhibits uniform appearance and consistent reconstitution behavior — critical quality attributes for researchers who demand batch-to-batch reproducibility in quantitative signaling assays.

Safety, Handling & Laboratory Precautions

This product is intended solely for use by qualified researchers in appropriately equipped laboratory environments. Standard laboratory safety protocols must be observed at all times, including the use of personal protective equipment such as gloves, eye protection, and lab coats. Avoid inhalation of lyophilized powder. This compound has not been evaluated for safety in humans or animals and must not be administered to any living organism. All handling, storage, and disposal should comply with applicable institutional and regulatory guidelines governing research-grade peptides.

Reconstitution, Packaging & Storage

The Mod GRF & Hexarelin Blend is supplied in a sealed, sterile vial as a lyophilized solid intended for laboratory reconstitution using appropriate research-grade solvents. Reconstitution is strictly for in vitro or preclinical analytical use only. Upon reconstitution, aliquot promptly and store at −20°C to −80°C to minimize degradation. Lyophilized product should be stored at 2°C–8°C or below when not in active use, protected from light and moisture. Do not freeze-thaw repeatedly. Packaging is designed to maintain product integrity throughout international shipping and cold-chain logistics.

Intended Research Use & Market Positioning

The Mod GRF & Hexarelin Blend is positioned as a premier dual-secretagogue research tool for endocrinology, neuroendocrinology, and cellular signaling laboratories. Its primary research applications include the study of synchronized growth hormone exocytosis, somatotroph receptor crosstalk, GHS-R1a and GHRHR co-activation kinetics, and downstream intracellular signaling cascades such as cAMP accumulation and intracellular calcium mobilization. This formulation is of particular interest to investigators modeling synergistic secretagogue interactions without the logistical complexity of independently weighing and combining two separate peptide compounds. Researchers looking to order a high-purity, analytically verified growth hormone secretagogue blend for sale will find this product ideally suited to demanding experimental protocols.
