Powder Description
GHRP-2 is also named: GHRP-2 Acetate. CAS NO.: 158861-67-7. GHRP-2 (also known as KP 102) is a synthetic hexapeptide Growth Hormone Releasing Peptide (GHRP), which acts on the hypothalamus and the pituitary gland to release growth hormone with a slight stimulator effect on Prolactin, ACTH and Cortisol levels. GHRP-2 is considered to be a true hGH secretagogue, meaning that it stimulates the body’s own secretion of hGH. Human Growth hormone has been shown in studies to promote lean body mass and reduce adiposity (fat). GHRP2 has demonstrated that it is very effective at stimulating GH production in research test subjects. It has a short half life with peak concentrations occurring around 15 minutes and not longer than 60 minutes after administration. Storage Guidelines
Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides References

Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.
Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.
Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.
In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
