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.

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

Trifluoroacetic acid (TFA) has a significant impact on peptides due to its role in the peptide synthesis process.

TFA is essential for the protonation of peptides that lack basic amino acids such as Arginine (Arg), Histidine (His), and Lysine (Lys), or ones that have blocked N-termini. As a result, peptides often contain TFA salts in the final product.

TFA residues, when present in custom peptides, can cause unpredictable fluctuations in experimental data. At a nanomolar (nM) level, TFA can influence cell experiments, hindering cell growth at low concentrations (as low as 10 nM) and promoting it at higher doses (0.5–7.0 mM). It can also serve as an allosteric regulator on the GlyR of glycine receptors, thereby increasing receptor activity at lower glycine concentrations.

In an in vivo setting, TFA can trifluoroacetylate amino groups in proteins and phospholipids, inducing potentially unwanted antibody responses. Moreover, TFA can impact structure studies as it affects spectrum absorption.
