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

GHRP-2 and Ipamorelin are two of the most extensively studied synthetic growth hormone secretagogues (GHS) available to the research community, each offered here at ≥98% purity in a standardized multi-vial kit configuration. This dual-peptide platform is supplied exclusively by The Peptide Store for in-vitro and preclinical laboratory investigation of GHS-R1a receptor dynamics, comparative agonist kinetics, and neuroendocrine signaling pathways. 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 delivers a precision-formatted, dual-secretagogue research platform engineered for laboratories investigating ghrelin receptor subtype mechanics, GHS-R1a agonist selectivity, and amplified growth hormone (GH) secretion profiles. Each kit contains five 5mg vials of GHRP-2 and five 5mg vials of Ipamorelin — a standardized 10-vial configuration that enables reproducible, side-by-side experimental design across endocrinology, metabolism, and biochemistry research settings. Both peptides target the same primary receptor axis yet exhibit meaningfully distinct structural architectures, yielding divergent selectivity, potency, and receptor desensitization profiles that make this combination uniquely valuable for comparative in-vitro study.

Peptide Structure & Amino Acid Sequence

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide with the sequence D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH₂, engineered to potently activate the GHS-R1a receptor with a high binding affinity. Its non-natural D-amino acid substitutions confer proteolytic resistance relative to endogenous ghrelin. Ipamorelin is a pentapeptide with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂, distinguished by its high receptor selectivity and notably reduced off-target stimulation of cortisol and prolactin release compared to earlier-generation GHRPs. Together, these structural contrasts make this kit an ideal model system for mapping receptor subtype selectivity and cross-agonist cell signaling variations in controlled laboratory environments.

Purity & Analytical Verification (HPLC & MS)

Every vial within this research kit is manufactured to a minimum purity of ≥98%, verified by high-performance liquid chromatography (HPLC). Mass spectrometry (MS) confirmation is applied to authenticate molecular identity and sequence integrity for both GHRP-2 and Ipamorelin. Analytical certificates are available upon request and reflect lot-specific data, ensuring full traceability for laboratory documentation and publication-grade reproducibility.

Quality Control & Lyophilization Integrity

Both peptides in this kit undergo rigorous multi-stage quality control protocols prior to dispatch. Lyophilization is performed under controlled vacuum conditions to produce a stable, low-moisture powder that resists degradation during transit and storage. Vial integrity is inspected prior to packaging, and each unit is sealed under inert atmosphere to preserve peptide structure. Batch-level QC records encompass identity testing, purity profiling, and visual inspection standards aligned with current research-grade manufacturing expectations.

Safety, Handling & Laboratory Precautions

These peptides are supplied strictly for qualified researchers operating within appropriately equipped laboratory environments. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and lab coats — should be worn at all times when handling lyophilized or reconstituted peptide material. Researchers should consult applicable institutional biosafety guidelines and relevant Safety Data Sheets (SDS) before commencing any experimental protocol. Peptide material should never be handled outside of a controlled research setting.

Reconstitution, Packaging & Storage

Each vial is supplied as a lyophilized powder suitable for reconstitution using standard laboratory-grade aqueous solvents appropriate to the experimental protocol. Reconstitution methodology should be determined by the principal investigator in accordance with the specific assay requirements. Upon receipt, vials should be stored at −20°C for long-term preservation. Once reconstituted, solutions should be kept at 2–8°C and used within a timeframe consistent with established peptide stability guidelines for the specific assay conditions.

Intended Research Use & Market Positioning

This dual-peptide kit is positioned as a premium, research-grade tool for laboratories investigating neuroendocrine feedback loops, GHS-R1a receptor down-regulation thresholds, comparative secretagogue potency, and cross-agonist intracellular signaling cascades. The standardized 5mg-per-vial format supports multi-replicate experimental design and enables consistent dosimetric modeling across extended study timelines. The Peptide Store supplies this kit to academic, pharmaceutical, and independent research institutions worldwide seeking reliable, high-purity reference material for secretagogue biology.
