What labs study it for

Skin and connective-tissue research. Labs add it to cultured skin cells (fibroblasts) to study how cells build collagen and the other structural proteins that hold tissue together, and how copper is carried into cells.

What this compound is

GHK-Cu is a copper complex of the tripeptide glycyl-L-histidyl-L-lysine. The peptide occurs in human plasma and binds copper(II) ions with high affinity, which is what the Cu in the name denotes. Laboratory work uses it as a defined copper-delivery tool in cell-culture studies of extracellular matrix components such as collagen, and in connective tissue models. It is not approved for any medical use.

What labs study it for

Metabolism and hormone-receptor research. Labs use it to study how one molecule can switch on three different hormone receptors at once (GLP-1, GIP and glucagon), and how that signalling plays out in cell and animal models of energy balance.

What this compound is

Retatrutide is a synthetic investigational peptide designed as a single molecule acting at three receptors: GIP, GLP-1 and glucagon. It is a long synthetic chain carrying a fatty-acid modification that extends its half-life. It is investigational, has not been approved by any regulatory authority anywhere in the world, and is supplied strictly as a laboratory reagent.

What labs study it for

Tissue and blood-vessel research. Labs use it in cell cultures and rodent models to study how cells move, how new small blood vessels form, and how gut lining tissue behaves.

What this compound is

BPC-157 is a laboratory-made peptide of fifteen amino acids. The laboratory that originated it reported the sequence as a section of a larger Body Protection Compound said to occur in human gastric juice, which is where the name comes from; that parent protein has not been independently isolated or sequenced by other groups. In the laboratory it is used as a tool compound in cell-culture and rodent studies of cell migration, blood-vessel formation (angiogenesis) and nitric-oxide signalling. Published work comes largely from a small number of research groups, is early-stage, and has not been established in humans; it is not approved for any medical use.

What labs study it for

Inflammation research. Labs use this tiny three-amino-acid peptide to study inflammatory signalling in cultured cells and in models of the gut lining and skin.

What this compound is

KPV is a peptide of just three amino acids: lysine, proline and valine. The sequence is the tail end (residues 11-13) of alpha-melanocyte-stimulating hormone, a signalling molecule involved in pigmentation and inflammatory regulation. Because it is the smallest active fragment, laboratories use it as a probe for melanocortin-related inflammatory signalling in cultured cells and in animal models of mucosal inflammation, without the pigmentation activity of the full hormone. It is not approved for any medical use.

Cell-energy research. Labs use it as a standard ingredient in enzyme tests and in studies of how cells produce energy, maintain their DNA, and regulate ageing-related enzymes called sirtuins.

What this compound is

NAD+ (nicotinamide adenine dinucleotide) is not a peptide at all but a coenzyme: a small molecule present in every living cell, where it carries electrons between chemical reactions and serves as a substrate for enzymes including the sirtuins and PARPs. It is among the most studied molecules in cell biology and is used in laboratories as a defined reagent in enzyme assays and metabolic studies. Supplied as a research chemical; not approved for any medical use.

What this compound is

Tesamorelin is a synthetic 44-amino-acid analogue of growth-hormone-releasing hormone, modified at one end with a trans-3-hexenoyl group to resist enzymatic breakdown. Laboratories use it as a defined agonist tool for studying the GHRH receptor and the growth-hormone axis.

What labs study it for

Growth-hormone research. Labs use this long-lasting version of a growth-hormone-releasing signal to study how sustained receptor activation behaves, and how attaching a molecule to blood proteins extends its lifetime.

What this compound is

CJC-1295 with DAC is a synthetic analogue of a growth-hormone-releasing hormone fragment, carrying a Drug Affinity Complex group that binds serum albumin and greatly extends its circulating half-life. Laboratories use it as a long-acting GHRH-receptor agonist tool in endocrine signalling studies. It is not approved for any medical use in any jurisdiction.

What labs study it for

Mitochondria and cell-energy research. Labs use it to study how mitochondria, the cell's power plants, send signals to the rest of the cell, including the AMPK energy-sensing pathway.

What this compound is

MOTS-c is a peptide of sixteen amino acids, unusual in its origin: it is encoded not by the cell nucleus but by mitochondrial DNA, within the 12S ribosomal RNA gene. Peptides of this kind are called mitochondrial-derived peptides, and MOTS-c was among the first identified. Laboratory research examines its role in AMPK signalling and folate-methionine metabolism, and its behaviour as a signalling molecule between mitochondria and the rest of the cell, principally in cell culture and rodent models.

What this compound is

Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of growth-hormone-releasing hormone, the shortest fragment that retains full receptor activity. Laboratories use it as a reference GHRH-receptor agonist in endocrine studies. Sermorelin was formerly marketed as an approved drug product in the United States; the material supplied here is a laboratory reagent and is not that product.

GHRH receptor pharmacology · Endocrine signalling models

What labs study it for

Growth-hormone research. Labs use it because it acts on just one receptor (the ghrelin receptor), letting them study that single pathway without switching on others.

What this compound is

Ipamorelin is a synthetic pentapeptide developed as a selective agonist at the growth-hormone secretagogue receptor (GHS-R1a), the receptor that also responds to the hormone ghrelin. That selectivity is what makes it useful in the laboratory: it isolates GHS-R1a signalling from other endocrine pathways in cell and animal models. It is not approved for any medical use.

What labs study it for

Cell-growth research. Labs add it to cell cultures to support cell growth in the dish, and use it to study IGF-1 receptor signalling.

What this compound is

IGF-1 LR3 is an engineered analogue of insulin-like growth factor 1, a naturally occurring protein of 70 amino acids. The analogue carries a 13-residue extension at one end and a single substitution at position 3, changes that sharply reduce its binding to IGF-binding proteins. Laboratories use it as a cell-culture supplement and as a tool for studying IGF-1 receptor signalling with reduced binding-protein interference. It is not approved for any medical use.
