Description
GHRP-2 5 mg: research material
Buy GHRP-2 5 mg for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial.
GHRP-2, also called pralmorelin or growth hormone-releasing peptide-2, is a synthetic six-amino-acid peptide studied for its ability to stimulate growth hormone secretion in experimental systems.
Choose the material and presentation
Choose the 5 mg presentation for the labeled amount your laboratory requires. GHRP-2 is the research reagent; growth hormone is the separate protein measured in release assays. GHRP-6 and Ipamorelin are different compounds, so equal milligram amounts do not establish equivalent activity.
The vial label specifies material amount, not solution concentration. Concentration depends on the preparation volume and the basis used for the amount. For molar calculations, verify the supplied chemical form and corresponding molecular weight in the product records.
Other presentations: GHRP-2 10 mg.
What GHRP-2 cell studies measured
In a rat pituitary-cell comparison, Cheng and colleagues measured growth hormone release after exposure to GHRP-2 and GHRP-6. Combining maximal concentrations did not increase the response beyond either peptide alone. Cross-desensitization and antagonist experiments led the authors to infer a shared mechanism in that model.
A separate bovine pituitary-cell study examined signaling with pathway inhibitors and measured hormone in the culture medium. A calcium-channel blocker inhibited the response. Unlike the rat comparison, a growth hormone-releasing factor receptor antagonist also blocked GHRP-2-stimulated secretion.
These findings illustrate why species, cell preparation and controls belong with an interpretation. A result in one culture system does not establish an identical pathway in another. Hormone-release measurements also answer a different question from a direct receptor-binding assay. Neither paper establishes the activity of a particular supplied lot or a benefit for human use.
Product records and batch reports
The COA and documents tab provides available reports and product files. Match the compound, presentation and lot before comparing results. An HPLC purity result describes the chromatographic measurement; it is not a hormone-release or receptor-activity test.
Use the documentation supplied for this material when planning storage and handling. A shelf-life or solvent instruction from another supplier cannot establish stability for this lot. If the record does not answer a requirement of your assay, request clarification before relying on it.
