Hexarelin is a synthetic hexapeptide that belongs to a class of growth hormone-releasing peptides (GHRPs). It is also known as examorelin, EP-23905, and MF-6003. The amino acid sequence of hexarelin is His - D-2-methyl - Trp - Ala - Trp - D-Phe - Lys -NH2. This hexapeptide was derived from GHRP-6 (growth hormone-releasing peptide 6),...

CJC-1295 & Ipamorelin & GHRP-2 are peptides that appear to have an affinity for receptors in the central nervous system. More specifically, they may interact with the pituitary gland cells and the hypothalamus. They are hypothesized to exert neuroendocrine actions, and their potential is tightly linked to their distinctive structures. CJC-1295 belongs to a class...

NAD+ peptide (nicotinamide adenine dinucleotide) is a coenzyme that plays a potential role in various biological processes, particularly in cellular metabolism. It is derived from the B-vitamin niacin (vitamin B3) in redox reactions, transferring electrons during metabolic reactions. NAD+ exists in two forms: oxidized (NAD+) and reduced (NADH). The scientific theory posits that the oxidized...

N-Acetyl Selank is an acetylated form of the heptapeptide Selank. Selank is a synthetic analog of the natural tetrapeptide tuftsin (threonine - lysine - proline - arginine). The sequence of N-Acetyl Selank is acetyl - threonine - lysine - proline - arginine - proline - glycine - proline. Adding proline - glycine - proline at...

Acetyl Hexapeptide-3 (Argireline) is a synthetic peptide used in scientific research. It is a chain of six amino acids connected in a specific sequence: N-acetyl - L-alpha-glutamyl - L-alpha-glutamyl - L-methionyl - L-glutaminyl - L-arginyl - L-arginine amide. Acetyl Hexapeptide-3 has gained attention for its potential molecular mechanisms that may interact with the release of...

Kisspeptin-10, aka Metastin (45-54) or KP 45–54, is a peptide that is derived from the cleavage of Kisspeptin-54, which itself is produced from a precursor polypeptide encoded by the KISS1 gene. Kisspeptins are naturally produced by hypothalamic cells in the central nervous system. The kisspeptin (KISS1) gene, found in those cells, encodes a 145-amino acid...

N-Acetyl Semax is a synthetic peptide that is an acetylated version of Semax. Like Semax, it consists of a 4 amino acid fragment (Met-Glu-His-Phe), a common part in the sequence of all melanocortin hormones, such as the adrenocorticotropic hormone (ACTH), and a Pro-Gly-Pro fragment as a stabilizer, that is attached at the C-terminus. The acetylation...

Gonadorelin (GnRH), also known as growth hormone releasing factor (GHRF), somatocrinin, or somatoliberin, is a decapeptide made of 10 amino acids and has the sequence: pyro-Glu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2. The first amino acid, pyro-Glu, is an unusual form of glutamic acid undergoing cyclization. Scientists consider this cyclization important for Gonadorelin's biological activity, as it may increase its stability...

PE-22-28 is a synthetic peptide analog of spadin, a protein naturally produced in the central nervous system. The sequence of PE-22-28 is based on a fragment of the spadin protein that corresponds to the chain from the 22nd to 28th amino acids of its sequence. More specifically, the amino acid sequence of PE-22-28 is Proline...
