Retatrutide
triple incretin agonist · GIP / GLP-1 / glucagon
Retatrutide (development code LY3437943) is the most-studied triple incretin agonist. It is the compound researchers reach for when the question involves engaging the glucagon receptor alongside the two incretin receptors — a step beyond the dual-agonist generation.

Tirzepatide
dual incretin agonist · GIP / GLP-1
Tirzepatide (LY3298176) is the reference compound for dual-incretin research — the first widely-studied peptide to co-agonise the GIP and GLP-1 receptors from a single molecule. It is the baseline that newer triple agonists are measured against.

Tesamorelin
GHRH analogue · growth-hormone secretagogue
Tesamorelin is a stabilised analogue of growth-hormone-releasing hormone (GHRH). It sits on the secretagogue side of the growth-hormone axis — studied for prompting the body's own pituitary to release GH, rather than supplying GH directly.

Somatropin
recombinant growth hormone · dosed in IU
Somatropin is recombinant human growth hormone (rhGH) — growth hormone itself, produced by recombinant expression. Unlike the secretagogues in this range, it supplies GH directly rather than stimulating the pituitary to release it.

CJC-1295 + Ipamorelin
GHRH analogue + selective GHRP · secretagogue pairing
CJC-1295 and Ipamorelin are the most-studied secretagogue pairing on the growth-hormone axis. They are combined because they act through two different receptors — a GHRH analogue and a selective GH-releasing peptide — rather than duplicating one mechanism.

BPC-157
synthetic pentadecapeptide · tissue-repair research
BPC-157 is a stable, synthetic pentadecapeptide — a 15-amino-acid sequence derived from a body-protection compound. It is one of the two most-studied peptides in tissue-repair research, and is frequently examined alongside TB-500 because the two are associated with different repair pathways.

TB-500
thymosin β4-related peptide · tissue-repair research
TB-500 is a synthetic peptide related to thymosin β4, a naturally occurring protein involved in cell structure. In repair research it is the counterpart to BPC-157 — associated with a different pathway, which is why the two are so often studied together.

NAD+
redox coenzyme · cellular-energy research
NAD+ (nicotinamide adenine dinucleotide) is a fundamental coenzyme found in every cell. Unlike the receptor-targeting peptides elsewhere in the catalogue, it is studied as a metabolic <em>substrate</em> — a core component of how cells produce and manage energy.

MOTS-c + SS-31
mitochondrial-signalling peptides
MOTS-c and SS-31 are two peptides studied around mitochondrial function — the cell's energy machinery. They are combined because they approach the mitochondrion from different angles: one is mitochondrial-derived, the other mitochondria-targeting.

GHK-Cu
copper-binding tripeptide · skin & matrix research
GHK-Cu is a copper-binding tripeptide — a three-amino-acid sequence that carries a copper ion. It is the compound at the centre of copper-peptide research, studied in skin-remodelling, collagen and extracellular-matrix models.

Melanotan II
melanocortin agonist · MC1 / MC4
Melanotan II is a synthetic melanocortin-receptor agonist. It is studied across more than one melanocortin receptor, which is why it appears in pigmentation research — and why it is the broader counterpart to the MC4-focused PT-141.
