Description
Growth Hormone Releasing Peptide-6, or GHRP-6, is a hexapeptide that has been extensively studied for its role in stimulating the secretion of growth hormone by targeting specific receptors in vitro. This compound is an indispensable tool for exploring the regulatory pathways of endocrine signaling and growth hormone release.
GHRP-6 was synthesized using advanced peptide technology to ensure a high degree of purity and stability, making it suitable for a wide range of laboratory applications. Its unique sequence enables precise interaction with ghrelin receptors, providing insight into metabolic processes, cell growth, and hormone regulation in controlled research settings. GHRP-6 is presented as a lyophilized powder to preserve its integrity and ensure longevity during storage and handling.
This peptide is classified as Research Use Only (RUO). Labs who are ordering this compound must refer to our terms and conditions for compliance guidelines and confirm that it is solely for in vitro research purposes, not for human or veterinary applications.

Storage Protocols
Proper storage is critical to maintaining the stability and efficacy of Growth Hormone Releasing Peptide-6. Exposure to suboptimal conditions can lead to degradation and reduced performance in research applications. Consistent storage conditions are recommended to preserve product integrity.
| Storage Condition | Duration |
| Frozen (-20°C) | Up to 3 years |
| Refrigerated (4°C) | Up to 3 months |
| After Reconstitution | Use within 28 days at 4°C |
- Store in a tightly sealed container to avoid contamination.
- Protect from light to maintain chemical stability.
- Avoid repeated freeze-thaw cycles to prevent degradation.

Lone Star Research Storage Protocols:
Lone Star Research employs advanced storage solutions, including medical-grade freezers and refrigeration systems. Backup generators and continuous temperature monitoring ensure product stability at all times. Temperature logs are recorded to the cloud and audited quarterly to maintain high standards.
Lonestar Reconstitution Protocols:
Growth Hormone Releasing Peptide-6 is reconstituted under stringent conditions, following sterility guidelines in controlled environments with negative pressure. Reconstituted chemicals are non-returnable due to their sensitive handling requirements.


Lyophilized Powder (Standard)
A freeze-dried, stable form of the chemical, ideal for long-term storage. Typically stable for up to 2 years when stored properly. Keep frozen at -20°C to maintain stability.
Reconstituted (Ready-to-Use) A pre-prepared, liquid form reconstituted with up to 2.5 mL of bacteriostatic water for convenience. Use within 28 days when stored at 4°C after reconstitution.
Signs of Degradation (After Reconstitution):
- Formation of particulates or cloudiness.
- Loss of clarity or discoloration.
- Reduced bioactivity in research applications.
Proper handling and storage are essential to maintain the efficacy of most peptides. Lone Star Research is not responsible for mishandling or temperature fluctuations after the product leaves our facility. Please see our Return policy for more details.
