GHRP-2 Ipamorelin Peptide Stack

Direct Anti Peptide offers the GHRP-2 Ipamorelin Peptide Stack, a dual-compound research formulation supplied at ≥98% purity and verified by independent analytical testing. This stack combines two well-characterized synthetic peptides studied for their complementary roles in growth hormone secretagogue research. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

The GHRP-2 Ipamorelin Peptide Stack is a paired research formulation comprising two distinct growth hormone secretagogue peptides. GHRP-2 (Growth Hormone Releasing Peptide-2) and Ipamorelin are both synthetic compounds that have attracted significant scientific interest for their individual and combined roles in stimulating growth hormone (GH) release pathways. Researchers investigating GH pulsatility, metabolic signaling, and secretagogue receptor activity frequently utilize this combination as a dual-mechanism model system. Available exclusively through Direct Anti Peptide for legitimate laboratory and preclinical research applications.

Peptide Structure & Amino Acid Sequence

GHRP-2 is a synthetic hexapeptide with the amino acid sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH₂. It functions as a synthetic agonist of the ghrelin receptor (GHS-R1a), directly stimulating GH secretion from the anterior pituitary. Its molecular formula is C₄₅H₅₅N₉O₆, with a molecular weight of approximately 817.9 g/mol.

Ipamorelin is a selective pentapeptide ghrelin mimetic with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂. It is characterized by its high selectivity for the GHS-R1a receptor, with minimal off-target effects on cortisol or prolactin pathways compared to other secretagogues. Its molecular formula is C₃₈H₄₉N₉O₅, with a molecular weight of approximately 711.9 g/mol.

Purity & Analytical Verification (HPLC & MS)

Both peptide components within this research stack are manufactured to a minimum purity of ≥98%, confirmed through rigorous analytical protocols. Each batch undergoes High-Performance Liquid Chromatography (HPLC) to quantify purity and detect any residual impurities. Mass Spectrometry (MS) is applied to confirm the precise molecular identity and structural integrity of each compound. Certificates of Analysis (CoA) reflecting these results are available upon request from Direct Anti Peptide, ensuring full analytical traceability for every order.

Quality Control & Lyophilization Integrity

Each compound in the GHRP-2 Ipamorelin Peptide Stack is produced using solid-phase peptide synthesis (SPPS) under controlled GMP-aligned conditions. Following synthesis and purification, both peptides are lyophilized (freeze-dried) to produce stable, moisture-free powder. This lyophilization process preserves molecular integrity during transit and long-term storage. Strict quality control checkpoints are applied at each stage of production to ensure batch-to-batch consistency across all Direct Anti Peptide research-grade products.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by qualified researchers and trained laboratory professionals operating within appropriate institutional or regulatory frameworks. Standard laboratory personal protective equipment (PPE) — including gloves, safety glasses, and lab coats — should be worn when handling lyophilized peptide materials. Avoid inhalation of powder. All handling should occur in a controlled laboratory environment in compliance with applicable institutional biosafety protocols. This product is not intended for human or veterinary administration under any circumstances.

Reconstitution, Packaging & Storage

Upon receipt, both vials should be inspected for seal integrity and stored immediately under recommended conditions. For long-term preservation, store lyophilized peptides at -20°C in a frost-free freezer, away from direct light and moisture. For short-term use, storage at 2–8°C is acceptable for up to 4 weeks. Reconstitution should be performed using appropriate laboratory-grade solvents in accordance with the specific requirements of the intended research protocol. Reconstituted solutions should be aliquoted and stored at -80°C to minimize freeze-thaw degradation. All reconstitution procedures must be conducted within a validated laboratory setting.

Intended Research Use & Market Positioning

The GHRP-2 Ipamorelin Peptide Stack is positioned as a premium dual-compound research tool for scientists investigating GH secretagogue receptor pharmacology, hypothalamic-pituitary axis signaling, metabolic research models, and comparative secretagogue studies. The synergistic receptor activity profile of GHRP-2 and Ipamorelin makes this stack a valuable reference combination for in vitro and preclinical in vivo research contexts. Direct Anti Peptide supplies this stack to academic institutions, pharmaceutical research organizations, and certified independent laboratories.
