- Foundational neuroendocrine research
What is GHRH (GH Releasing Hormone)?
The exact 44-amino acid peptide your hypothalamus naturally produces.
Listed vial contents: 5mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.
What mechanisms are being studied?
Native GHRH is the exact 44-amino acid peptide produced by the hypothalamus to control pituitary GH secretion. It binds GHRH-R on pituitary somatotrophs, activating the cAMP/PKA pathway to stimulate both GH synthesis and secretion. As the endogenous reference molecule, it provides the benchmark against which all synthetic GHRH analogs are measured.
What are the research questions?
- Reference standard: Essential for comparative research against modified GHRH analogs.
- GH axis diagnostics: Used to differentiate hypothalamic vs pituitary causes of GH deficiency.
- Neuroendocrine research: Foundational tool for studying the GH axis, somatotroph biology, and GHRH-R signaling.
What does the published work describe?
Guillemin R et al. (Science 1982) — Nobel Prize-winning isolation and characterization. Native GHRH maintains pulsatile GH release without receptor desensitization in physiological dosing. Short half-life (7-10 minutes due to DPP-4 degradation) limits therapeutic utility.
What are the limits of this evidence?
The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?
Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.
How is GHRH (GH Releasing Hormone) handled in the lab?
For GHRH (GH Releasing Hormone), record the product code GHRH-5, selected strength and lot before opening. Follow the material-specific safety data sheet and laboratory SOP, with appropriate gloves, eye protection and containment. For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
Choose a solvent for GHRH (GH Releasing Hormone) from the documented sequence or chemical identity, salt form and assay requirements. Test a small portion first and record pH, solvent composition and clarity. Do not assume one diluent works for every research material; include a solvent-only control and establish compatibility before using the stock in an assay.
For GHRH (GH Releasing Hormone), calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; the catalog lists 5040.4 g/mol as a reference, not lot confirmation. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
Use the documented storage conditions for the supplied GHRH (GH Releasing Hormone) form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
A GHRH (GH Releasing Hormone) laboratory protocol should record identity, product code GHRH-5, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Research Use Only. Not for human consumption, therapeutic, veterinary or any in-vivo use.

Quality & Verification
GHRH (GH Releasing Hormone) has a catalog purity specification of ≥98%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
