Storage & handling: Store at 2–8 °C (≤ –20 °C long-term), away from light. Ships at ambient temperature.
How we test
Certificates are issued by independent labs. Identity and purity are measured by LC-MS; endotoxin, where listed, by a LAL screen. The latest report for this option: , lot , tested .
How to read your COA
Start with the lot number on the report. Identity confirms by mass spectrometry that the molecule is the one on the label. Purity is the share of the sample that is the target peptide, measured by LC-MS. Endotoxin, where tested, is screened by LAL and must sit below 0.5 EU/mL. The lab name and test date show who ran it and when.

Research-grade synthetic hexapeptide supplied in a format for controlled in vitro investigation of GHS-R1a receptor binding and intracellular signaling assays.
Product overview
GHRP-2 (10mg) is a synthetic hexapeptide supplied for controlled laboratory research. This higher-quantity format supports research programs running extended assay series or multi-condition study designs. Each batch is verified by Certificate of Analysis (COA) for molecular identity and analytical purity.
This product is supplied strictly for research use only.
Research focus
GHRP-2 appears in published research examining receptor–ligand binding and downstream signaling in controlled in vitro systems.
Common research contexts include:
- GHS-R1a receptor binding assays
- Receptor selectivity profiling across related peptide analogues
- Intracellular signaling readouts such as cAMP and calcium dynamics
- Structure–activity relationship (SAR) studies within secretagogue-class peptides
GHS-R1a is a receptor name used in scientific literature. It is a cell surface protein. It converts binding events into intracellular signals.
All references describe in vitro experimental models only.
Methodological notes
GHRP-2 is supplied as a lyophilized powder. Lyophilized means freeze-dried for stability.
Recommended handling conditions:
- Store in a cool, dry, light-protected environment
- Keep sealed until use in a controlled laboratory setting
- Protect from moisture and heat
- Reconstitute using sterile laboratory techniques and validated solvents
- Prepare aliquots when needed to reduce freeze–thaw exposure
- Handle only by qualified personnel under institutional laboratory protocols
This compound is not intended for use outside approved research environments.
Quality & sourcing
Each batch is supported by quality documentation and analytical verification, including:
- LC-MS purity testing
- Mass spectrometry identity confirmation
- Batch traceability and COA documentation
These controls support reproducibility and consistency across extended research programs.

Researchers often ask
Is GHRP-2 for human use?
No. GHRP-2 is sold for laboratory research only. It is not for human or veterinary use, and it is not a drug, food or cosmetic.
How do I find the lab report?
Use View COAs on the product page, or search the COA library by compound name. The summary is public; the signed PDF reports are available to signed-in researchers.
Why is purity measured by LC-MS?
LC-MS separates the sample and identifies each component by its mass, so one run confirms identity and measures purity.
When will my order ship?
Orders are dispatched within 24–48 business hours. Regular tracked delivery takes 5 to 10 days and express tracked 3 to 5 days. Regular shipping is free on orders over $200 and express on orders over $400, after discounts.
