GHRP-2 is a synthetic growth hormone secretagogue peptide studied for its ability to stimulate pulsatile growth hormone release. It is part of the broader class of ghrelin receptor agonists and has been widely used in experimental endocrine and metabolic research. Compared with newer secretagogues such as Ipamorelin, GHRP-2 is generally considered more potent but also less selective in downstream hormonal effects.

Note: This product is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water for appropriate research handling.

Most researchers also add BAC Water 3ML to their order for convenience.

GHRP-2 is a small synthetic peptide belonging to the growth hormone releasing peptide family. It acts primarily through the growth hormone secretagogue receptor, also known as the ghrelin receptor. In laboratory settings, it is typically supplied as a lyophilized powder for reconstitution prior to controlled use in research protocols.

GHRP-2 has been explored in preclinical and translational research involving:
• Growth hormone axis stimulation
• Recovery and anabolic signaling models
• Appetite and feeding behavior research
• Endocrine pathway interaction studies
• Metabolic and body composition research

Because it may influence multiple hormonal pathways beyond growth hormone alone, it is often used in comparative studies against more selective secretagogues.

GHRP-2 binds to and activates the growth hormone secretagogue receptor. This receptor is expressed in the pituitary and hypothalamus and plays a role in growth hormone release, appetite signaling, and neuroendocrine regulation. Activation of this pathway promotes release of growth hormone and may also affect prolactin, cortisol, and appetite-related signaling depending on dose and study design.

In experimental settings, GHRP-2 has been shown to stimulate robust growth hormone release and has been used in studies examining anabolic pathways, endocrine function, and metabolic regulation. It has also been investigated in models involving appetite control and neuroendocrine signaling. Compared with more selective agents, GHRP-2 is often noted for stronger GH release but broader hormonal activity.

To protect experimental integrity, store peptides cold, dry, and shielded from light to minimize oxidation, contamination, and degradation. For near-term use, keep unopened material refrigerated at ≤4 °C (≤39 °F) and limit time at room temperature during handling. Lyophilized (dry) peptides can tolerate short periods at room temperature, but refrigeration is preferred for best stability and longevity. For longer-term storage, keep unmixed material frozen—−18 °C (0 °F) is acceptable, while −80 °C (−112 °F) is optimal for multi-month to multi-year preservation. Avoid frost-free freezers and repeated freeze–thaw cycles, which can accelerate breakdown. If reconstituted (in solution), use sterile buffer (ideally pH 5–6 when feasible), split into aliquots, and freeze (preferably −80 °C (−112 °F)) to reduce handling-related degradation.
