GHRP-2 (5mg x 10) Ipamorelin (5mg x 10)

GHRP-2 and Ipamorelin are two of the most extensively studied synthetic growth hormone secretagogues (GHS) available for laboratory research. This dual-peptide kit from The Peptide Store is manufactured to a minimum purity of ≥98%, verified by high-performance liquid chromatography (HPLC) and mass spectrometry (MS), making it an ideal platform for comparative receptor binding and neuroendocrine signaling studies. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

The GHRP-2 and Ipamorelin combination kit from The Peptide Store represents a precision-engineered, dual-peptide research platform designed to support advanced investigations into ghrelin receptor subtype mechanics, comparative GHS-R1a agonist kinetics, and amplified growth hormone (GH) secretion profiles. The 20-vial kit format — ten vials of each peptide — provides endocrinology, metabolism, and biochemistry laboratories with a standardized, reproducible baseline vehicle for examining neuroendocrine feedback loops, receptor down-regulation thresholds, and cross-agonist cell signaling variations. Both peptides are supplied in a lyophilized, sterile-filtered format, ensuring maximum stability and shelf integrity for extended research timelines.

Peptide Structure & Amino Acid Sequence

GHRP-2 (Growth Hormone Releasing Peptide-2), also known as Pralmorelin, is a synthetic hexapeptide with the sequence D-Ala-D-βNal-Ala-Trp-D-Phe-Lys-NH₂ and CAS number 158861-67-7. It is a potent, selective GHS-R1a agonist that stimulates robust GH release while also exhibiting moderate affinity for CD36 and other scavenger receptor pathways.

Ipamorelin is a synthetic pentapeptide with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂ and CAS number 170851-70-4. Unlike GHRP-2, Ipamorelin demonstrates a highly selective GHS-R1a binding profile with minimal off-target receptor interaction, making it a valuable comparator in selectivity-focused research models. The structural divergence between these two peptides yields meaningfully different desensitization kinetics and downstream signaling profiles, offering researchers a powerful dual-variable framework.

Purity & Analytical Verification (HPLC & MS)

Every vial in this kit undergoes rigorous analytical verification prior to release. Both GHRP-2 and Ipamorelin are confirmed at ≥98% purity using reverse-phase HPLC, with identity confirmation performed via electrospray ionization mass spectrometry (ESI-MS). Certificates of Analysis (CoA) are available upon request and reflect lot-specific analytical data, ensuring full traceability and reproducibility across research batches.

Quality Control & Lyophilization Integrity

Both peptides in this kit are produced under stringent quality control protocols. Lyophilization is performed using validated freeze-drying cycles to preserve peptide bond integrity, minimize oxidative degradation, and maintain consistent reconstitution profiles. Each vial is sealed under inert gas conditions and inspected for particulate matter, moisture content, and fill accuracy before shipment. This multi-stage QC process ensures that every unit delivered by The Peptide Store meets the reproducibility standards required for peer-reviewed laboratory research.

Safety, Handling & Laboratory Precautions

These compounds are intended exclusively for trained laboratory personnel operating within certified research environments. Standard laboratory safety protocols apply, including the use of appropriate personal protective equipment (PPE) such as gloves, lab coats, and eye protection. Researchers should consult applicable Safety Data Sheets (SDS) and adhere to institutional biosafety guidelines. These peptides are not approved for use in biological systems outside of controlled in vitro or ex vivo research frameworks.

Reconstitution, Packaging & Storage

Each vial contains a lyophilized peptide cake suitable for reconstitution using sterile, research-grade aqueous solvents in accordance with established laboratory protocols. Reconstituted solutions should be aliquoted, stored at −20°C, and used within timeframes consistent with validated stability data for each compound. The kit is packaged in a protective multi-vial format with tamper-evident sealing to preserve product integrity during transit and storage.

Intended Research Use & Market Positioning

This dual-peptide kit is specifically positioned for research teams investigating GHS-R1a receptor pharmacology, comparative secretagogue potency, neuroendocrine axis modulation, and receptor desensitization kinetics in mammalian model systems. It is an ideal procurement choice for academic institutions, contract research organizations (CROs), and pharmaceutical discovery teams requiring a standardized, high-purity comparative peptide platform.
