DAEFRHDSGYEVHHQKLVFFAEDVGSNKGAIIGLMVGGVVIA4514.1 Da
100 Da1 kDa10 kDa

Amyloid-beta 1-42 (Aβ42) is a 42-amino-acid peptide fragment that forms sticky plaques in the brains of people with Alzheimer's disease. It is produced when a larger protein called amyloid precursor protein (APP) is cut by specific enzymes. Researchers study it as both a disease marker and a potential therapeutic target.

100 Da1 kDa10 kDa

Epithalon (also spelled Epitalon, chemical abbreviation AEDG) is a synthetic tetrapeptide composed of four amino acids — alanine, glutamic acid, aspartic acid, and glycine — originally derived from a natural peptide secreted by the pineal gland. It was developed by Russian researchers studying how the pineal gland influences biological aging. At 390.35 Da, it is one of the smallest peptides actively studied in longevity and cancer biology.

Delta Sleep-Inducing Peptide (DSIP) is a small neuropeptide of nine amino acids, first isolated from rabbit cerebrospinal fluid in 1974 by Swiss researchers studying sleep regulation. It is found naturally in the brain, pituitary gland, and gut, and has been studied for its potential role in sleep, stress response, and neuroendocrine regulation.

100 Da1 kDa10 kDa

CJC-1295 DAC is a synthetic peptide analog of growth hormone-releasing hormone (GHRH), engineered to last far longer in the bloodstream than the natural hormone it mimics. The 'DAC' stands for Drug Affinity Complex, a chemical modification that allows the peptide to bind to albumin, a common blood protein, extending its half-life from minutes to approximately one week. It was developed to stimulate the pituitary gland to release more growth hormone over a sustained period.

Mod GRF 1-29, also known as Modified GRF 1-29 or CJC-1295 without DAC, is a synthetic 29-amino-acid peptide designed to mimic the natural growth hormone-releasing hormone (GHRH) that the body produces in the hypothalamus. It was engineered with four specific amino acid substitutions to make it more stable and longer-lasting than the original GHRH fragment. Researchers study it as a tool for stimulating the pituitary gland to release growth hormone in a pulse-like, physiologically natural pattern.
