Plain-English summaries: what it is, what it was studied for, safety and regulatory status, plus mixing and dosing charts.
A 16-amino-acid peptide encoded by mitochondrial DNA, studied for energy metabolism, insulin sensitivity and exercise.
An experimental 15-amino-acid peptide studied for tissue repair in lab and animal models.
Usually refers to a short, modified fragment of thymosin beta-4, not the full-length peptide used in most of the studies cited to support it.
A copper-binding peptide found in human plasma and studied in skin biology, cosmetics and wound repair.
A five-amino-acid peptide that triggers growth hormone release.
NAD+ is not a peptide; it is a coenzyme every cell uses for energy reactions.
A synthetic peptide that can darken skin. Regulators warn about serious side effects and unknown product contents, and a tan from it does not protect against sun damage.
A short-acting growth-hormone-releasing hormone (GHRH) analogue.
A long-acting growth-hormone-releasing hormone analogue that raises growth hormone and IGF-1 for days in humans.
A peptide that prompts the pituitary to release growth hormone.
An experimental four-amino-acid peptide studied for telomeres, aging and circadian rhythms.
A seven-amino-acid peptide studied mainly for anxiety in small Russian trials.
A seven-amino-acid peptide derived from ACTH and used clinically in Russia.
A natural reproductive hormone signal that sits upstream of GnRH, LH and FSH.
A three-amino-acid molecule your cells make to manage oxidative stress.
An experimental nine-amino-acid peptide whose name is more confident than its evidence.
A natural 37-amino-acid antimicrobial peptide involved in immune defense.
A synthetic version of gonadotropin-releasing hormone (GnRH), the signal that tells the pituitary to release LH and FSH.
A synthetic peptide that stimulates growth hormone release through the ghrelin receptor.
An eight-amino-acid cosmetic ingredient used in anti-wrinkle products.
A three-amino-acid synthetic peptide studied as a "bioregulator." Laboratory work on stressed nerve cells is interesting, but it has not been shown to treat memory, sleep, or aging problems in people.
An investigational peptide studied for small-fiber nerve damage (neuropathy).
A name tied to research on how the IGF-1 system responds to muscle loading.
An experimental compound designed to destroy the blood supply of white fat tissue.
A three-amino-acid bioregulator peptide studied for effects on blood-vessel lining cells.
A four-amino-acid bioregulator peptide studied mainly in lab models of chromatin, protein synthesis and digestive enzymes.
A three-amino-acid bioregulator peptide studied in cartilage cells and cellular aging.
A four-amino-acid bioregulator peptide studied for nerve tissue and gene expression.
A four-amino-acid synthetic peptide. Despite its name, the best-identified hormone studies involve thyroid function in birds, not testosterone in men.
A four-amino-acid bioregulator peptide studied in prostate tissue and cellular-aging experiments.
A three-amino-acid bioregulator peptide studied for effects on inflammatory signaling.
