Batch-specific documentation may include HPLC purity, identity confirmation and lot information. Refer to the supplied COA or the COA policy for current documentation scope.

Reconstitution and handling

Allow lyophilised material to equilibrate before opening to reduce condensation risk. Add validated solvent slowly down the vial wall, avoid vigorous shaking, and record the final concentration in the laboratory notebook or LIMS.

Use aseptic technique, calibrated pipettes or syringes, and validated diluent choices for the assay system. Reconstituted materials should be aliquoted where appropriate to reduce repeated freeze-thaw exposure.

Storage

Store unopened material according to the stated condition: -20°C recommended (research-only). Keep vials sealed, dry and protected from light. Reconstituted solutions should be stored under validated laboratory conditions and discarded according to internal SOPs and applicable research-waste rules.

Research-use statement

GHRP-2 5 mg is sold by Peptide Shop for research use only. It is not a medicine, food, cosmetic, supplement or diagnostic product. Buyers are responsible for ensuring lawful purchase, storage, handling and disposal under their institutional and local requirements.

FAQs

What is GHRP-2 used for in research?

GHRP-2 is used to study growth hormone secretion, ghrelin receptor activation, and somatotrope function. It's considered more selective than GHRP-6 with less appetite stimulation.

How is GHRP-2 different from GHRP-6?

GHRP-2 is more selective for GH release with less appetite stimulation and lower cortisol/prolactin effects than GHRP-6, making it useful for studying isolated GH secretion.

What is another name for GHRP-2?

GHRP-2 is also known as Pralmorelin and was one of the first synthetic GH secretagogues studied clinically for GH deficiency research.

How should GHRP-2 be stored?

Store lyophilised GHRP-2 at -20°C. Once reconstituted, keep at 2-8°C and use within 4 weeks.

What purity is your GHRP-2?

Our GHRP-2 is ≥99% pure as verified by HPLC. Each batch includes a Certificate of Analysis.

Can it be combined with GHRH analogs?

Yes, GHRP-2 with GHRH analogs is a common research combination for studying synergistic GH release mechanisms.

How do I reconstitute GHRP-2?

Reconstitute in sterile bacteriostatic water. Add solvent slowly and gently swirl to dissolve.

What sizes are available?

GHRP-2 is available in 5mg and 10mg vials.

What is GHRP-2?

GHRP-2 is a synthetic hexapeptide (D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2) and potent GHSR-1a agonist. It is studied for growth hormone axis research, ghrelin receptor pharmacology, and metabolic pathway investigations. CAS number 158861-67-7.

How does GHRP-2 differ from ipamorelin in research?

GHRP-2 produces a strong GH pulse but also stimulates cortisol and prolactin release. Ipamorelin is more selective for GHSR-1a with minimal secondary hormonal effects. Researchers choose based on whether broad or selective GH stimulation is needed.

Can GHRP-2 and GHRP-6 be compared in the same study?

GHRP-2 and GHRP-6 target the same receptor (GHSR-1a) but differ in potency and secondary hormonal effects. They are useful as comparative research tools in GHSR pharmacology and growth hormone secretion studies.

What is the molecular weight of GHRP-2?

GHRP-2 molecular weight: 817.94 g/mol. Molecular formula: C45H55N9O6. CAS number 158861-67-7.
