Performance and Recovery
Plain-English summaries: what it is, what it was studied for, safety and regulatory status, plus mixing and dosing charts.
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 five-amino-acid peptide that triggers growth hormone release.
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 modified IGF-1 used in lab research. It is biologically active, but muscle-building, recovery and anti-aging claims are not established, and it is not the approved IGF-1 medicine.
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.
A synthetic peptide that triggers growth hormone release and increases appetite.
An investigational peptide studied for small-fiber nerve damage (neuropathy).
An experimental metabolic compound, not a peptide, widely used in labs to activate AMPK, the cell's energy sensor.
A name tied to research on how the IGF-1 system responds to muscle loading.
A pegylated version of mechano growth factor peptide, discussed in muscle-repair research.
A shortened form of insulin-like growth factor 1 that is more potent than regular IGF-1 in some lab tests.
A three-amino-acid bioregulator peptide studied in cartilage cells and cellular aging.
A four-amino-acid synthetic peptide. Despite its name, the best-identified hormone studies involve thyroid function in birds, not testosterone in men.
