Low research · no human trials

MOTS-c research education card

Mitochondrial peptide

MOTS-c: The Mitochondrial Peptide Researchers Are Watching

A small peptide that is encoded in mitochondrial DNA rather than in the nucleus, and a hot topic in metabolism research.

Low research · animal/observational

Ipamorelin research education card

GHS-R agonist

Ipamorelin Explained: A Selective Ghrelin-Receptor Peptide

A five-amino-acid peptide used to study how the pituitary releases growth hormone.

Low research · limited human data

Sermorelin research education card

GHRH analog

Sermorelin: The Discontinued GHRH Fragment, Explained

A 29-amino-acid piece of growth-hormone-releasing hormone with a short history as a prescription product.

Low research · past Rx withdrawn

5-Amino-1MQ research education card

Small-molecule NNMT inhibitor

5-Amino-1MQ: A Small Molecule, Not a Peptide

Sold alongside peptides but chemically a different thing: a small molecule that blocks an enzyme called NNMT.

Low research · animal/cell

Epithalon research education card

Tetrapeptide

Epithalon (Epitalon): A Cautious Look at an Aging-Research Tetrapeptide

Four amino acids, a lot of internet attention, and a thin evidence base from a single research group.

Low research · sparse, dated

Tesamorelin research education card

GHRH analog

Tesamorelin: One Approved Product, One Narrow Use

A longer, stabilized relative of sermorelin, and a rare peptide with a real FDA approval for a very specific condition.

Moderate research · narrow Rx

NAD+ research education card

Redox coenzyme

NAD+ Explained: The Coenzyme at the Center of Cell Energy

A molecule every cell depends on, explained as basic biochemistry rather than as a product claim.

Established biochemistry

CJC-1295 (No DAC) research education card

GHRH analog

CJC-1295 Without DAC: Understanding the Modified GRF (1-29) Form

What the letters DAC mean, and why the 'no DAC' version is a different research tool from the long-acting one.

Low research · short hormone studies

SS-31 (Elamipretide) research education card

Mitochondria-targeting peptide

SS-31 (Elamipretide): The Mitochondria-Targeting Tetrapeptide

A tiny peptide that homes in on the mitochondrial membrane and carries one narrow accelerated approval.

Mixed · one accelerated approval

KPV research education card

Tripeptide fragment

KPV: A Three-Amino-Acid Fragment Studied in Barrier Models

Just three amino acids long, cut from a larger hormone, and studied in gut-lining and mucosal models.

Low research · animal/cell

Thymosin Alpha-1 research education card

Thymic peptide

Thymosin Alpha-1: Real Human Trials, Mixed Results

One of the few peptides in this series with genuine human trials, and a good example of why results can be mixed.

Moderate research · mixed

CJC-1295 / Ipamorelin research education card

Research blend

CJC-1295 and Ipamorelin Together: Two Different Pituitary Signals

One ingredient talks to the GHRH receptor, the other to the ghrelin receptor. The evidence for each still has to stand on its own.
