GHRP-6 Peptide

Description

GHRP-6 Peptide Overview

GHRP-6 Peptide is a synthetic hexapeptide belonging to the growth hormone-releasing peptide (GHRP) family. It has been extensively investigated in laboratory research involving growth hormone secretion, growth hormone secretagogue receptor (GHSR) signaling, peptide pharmacology, and endocrine pathways.

GHRP-6 is a six-amino-acid peptide and is structurally distinct from GHRP-2, Ipamorelin, Sermorelin, and other growth-hormone-related research peptides. Its defined sequence and molecular characteristics make it suitable for controlled laboratory investigations.

For researchers, reliable identification is essential. The peptide sequence, molecular formula, molecular weight, HPLC purity, and batch-specific analytical documentation should correspond to the material supplied.

What Is GHRP-6 Peptide?

GHRP-6, or growth hormone-releasing peptide-6, is a synthetic hexapeptide that has been studied as a growth hormone secretagogue.

Research has demonstrated that GHRP-6 interacts with the growth hormone secretagogue receptor (GHSR), also known as the ghrelin receptor. This makes the compound relevant to laboratory studies investigating receptor signaling and mechanisms involved in growth hormone regulation.

Research applications may include:

• Growth hormone secretagogue research
• GHSR/ghrelin receptor studies
• Endocrine signaling
• Peptide pharmacology
• Receptor-binding research
• Synthetic peptide characterization
• Structure–activity relationship studies

GHRP-6 should not be confused with GHRP-2. Although both belong to the same research category, their amino-acid sequences and molecular properties are different.

Molecular Formula, Molecular Weight & Sequence

The commonly reported chemical specifications for GHRP-6 are:

Property  | Specification
Product name  | GHRP-6 Peptide
Peptide type  | Synthetic hexapeptide
Sequence  | His-D-Trp-Ala-Trp-D-Phe-Lys-NH₂
Peptide length  | 6 residues
Molecular formula  | C₄₆H₅₆N₁₂O₆
Molecular weight  | Approximately 873.0 g/mol
CAS number  | 87616-84-0

The sequence contains modified amino-acid residues, including D-tryptophan and D-phenylalanine. These structural features are important when confirming the identity of the material.

Researchers should compare the stated molecular weight with the observed mass obtained through appropriate analytical testing, such as mass spectrometry.

Purity

A typical research-grade specification for GHRP-6 Peptide may be:

Purity: ≥98% by HPLC

The actual analytical purity should be confirmed using the batch-specific Certificate of Analysis (COA).

Depending on the testing package, the COA may include:

• HPLC purity percentage
• HPLC chromatogram
• Mass spectrometry
• Calculated molecular weight
• Observed molecular weight
• Lot/batch number
• Testing date
• Net peptide quantity

Researchers should review documentation for the exact batch received rather than relying solely on a general product-page purity claim.

Appearance

Appearance: White to off-white lyophilized powder.

GHRP-6 Peptide may be supplied in lyophilized form for controlled laboratory storage and handling.

Minor differences in color or powder texture can occur because of manufacturing and drying conditions.

Visual inspection alone cannot establish peptide identity or purity. Researchers requiring confirmation should rely on appropriate analytical methods such as HPLC and mass spectrometry.

Available Vial Sizes

GHRP-6 Peptide can be offered in several quantities according to laboratory requirements and available inventory.

Common research vial sizes include:

• 2 mg
• 5 mg
• 10 mg
• 20 mg
• 50 mg

For many individual research projects, 5 mg and 10 mg formats are practical choices.

Larger quantities may be appropriate for laboratories conducting repeated analytical work or multiple research projects.

The product page should clearly state the net peptide quantity per vial.

Storage Recommendations

Appropriate storage helps protect synthetic peptide quality.

For lyophilized GHRP-6:

• Follow the storage temperature specified in the applicable product documentation.
• Keep the vial tightly sealed.
• Protect the peptide from excessive moisture.
• Minimize exposure to heat and direct light.
• Avoid unnecessary temperature cycling.
• Allow a cold vial to equilibrate appropriately before opening to minimize condensation.

Controlled frozen storage may be appropriate for long-term storage when supported by the manufacturer’s stability data.

Important: Exact storage requirements can vary according to formulation, packaging, and stability information. The instructions supplied with the specific batch should take priority.

Reconstitution Information

GHRP-6 Peptide is supplied as a lyophilized research material. When a laboratory protocol requires reconstitution, researchers should choose a compatible solvent and concentration according to their validated experimental requirements.

General laboratory considerations include:

1. Allow the sealed vial to reach a suitable temperature before opening.
2. Use an appropriate laboratory-grade solvent.
3. Introduce the solvent carefully.
4. Avoid unnecessarily vigorous agitation.
5. Allow sufficient time for dissolution.
6. Minimize excessive foaming.
7. Consider aliquoting when appropriate to reduce repeated freeze–thaw exposure.
8. Record the solvent, concentration, preparation date, and storage conditions.

There is no universal reconstitution volume that is appropriate for every experiment.

Researchers should determine the required concentration first and calculate the solvent volume necessary to achieve that concentration.

Intended Use — Research Use Only

GHRP-6 Peptide is intended exclusively for laboratory research.

It should not be represented as a dietary supplement, general wellness product, or approved therapeutic.

This material is not intended for human or veterinary administration.

Researchers are responsible for complying with applicable institutional procedures, laboratory safety requirements, and regulatory obligations concerning research chemicals.

Packaging & Shipping Information

GHRP-6 Peptide should be packaged appropriately to protect the lyophilized material during transportation.

Professional research packaging may include:

• Securely sealed vial
• Product identification label
• Net peptide quantity
• Lot/batch number
• Research-use-only statement
• Protective secondary packaging
• Batch-specific COA or analytical documentation, where applicable

Upon receipt, researchers should inspect the packaging and vial for visible damage.

The product name, quantity, lot number, and accompanying documentation should be checked for consistency before the material is added to laboratory inventory.

Shipping conditions should follow the product’s validated stability requirements and applicable transportation regulations.
