Anyone researching Epithalon will quickly encounter an apparent problem. Some scientific articles and websites call the peptide Epithalon. Others call it Epitalon. Occasionally, another spelling—Epithalone—also appears. So are Epithalon and Epitalon different peptides? Epithalon and Epitalon are generally used to refer to the same synthetic tetrapeptide associated with the amino-acid sequence Ala-Glu-Asp-Gly. The difference is...Read More

Semax and Selank are frequently mentioned together. Both are small synthetic peptides associated with Russian research, both have attracted interest within neuroscience, and both regularly appear in discussions surrounding cognitive and neurological research. This similarity can create the impression that they are closely related versions of the same peptide. They are not. Semax and Selank...Read More

Semax is frequently discussed within peptide and neuroscience research, but its unusual name creates a basic question: What does Semax actually stand for? Unlike peptide names such as KPV, where each letter directly represents an amino acid, Semax is not simply an abbreviation of its amino-acid sequence. Semax is a synthetic heptapeptide, meaning it contains...Read More

SS-31 is frequently discussed within mitochondrial research, but anyone exploring the scientific literature will quickly encounter another name: Elamipretide. This creates an obvious question: Is SS-31 the same as Elamipretide? Yes. SS-31 is the research designation associated with the peptide that became known as Elamipretide. The compound has also appeared under other names and development...Read More

MOTS-c is unusual even by peptide-research standards. Unlike many peptides whose genetic instructions originate within DNA in the cell nucleus, MOTS-c is associated with mitochondrial DNA. That immediately raises two common questions: What does MOTS-c stand for? and Is MOTS-c actually made by mitochondria? MOTS-c stands for Mitochondrial Open Reading Frame of the 12S rRNA-c....Read More

TB-500 and Thymosin Beta-4 are frequently discussed as though they are simply two names for the same molecule. That creates an important question: Is TB-500 actually the same as Thymosin Beta-4? The most accurate answer is: The terms are closely related, but they should not automatically be treated as interchangeable without knowing exactly what material...Read More

BPC-157 is frequently described online as a “naturally occurring peptide found in the human stomach.” That explanation sounds straightforward. It is also potentially misleading. So, is BPC-157 actually naturally occurring? The more accurate answer is that BPC-157 is generally described in the research literature as a synthetic 15-amino-acid peptide associated with research into a larger...Read More

NAD+ is frequently discussed alongside peptides in longevity, cellular metabolism and research communities. That association creates a surprisingly common misconception: Is NAD+ actually a peptide? No. NAD+ is not a peptide. It is a coenzyme called nicotinamide adenine dinucleotide. Peptides are chains of amino acids. NAD+ has a completely different molecular structure and belongs to...Read More

One of the most immediately noticeable characteristics associated with GHK-Cu is its colour. Unlike many peptides that are commonly encountered as white or off-white materials, GHK-Cu is associated with a distinctive blue coloration. This raises a surprisingly useful scientific question: Why is GHK-Cu blue? The answer is connected to the copper ion bound by the...Read More

Tirzepatide is commonly described as a dual GIP and GLP-1 receptor agonist. That explains how the molecule acts, but it raises another basic question: Is Tirzepatide actually a peptide? Yes. Tirzepatide is a synthetic peptide-based molecule consisting of 39 amino acids and engineered to activate both GIP and GLP-1 receptors. Its structure is based primarily...Read More
