MOTS-c: A Mitochondrial-Derived Peptide in Metabolic Research

Back to Research Library Evidence reviewed: 1 November 2026Author: ExtolX Editorial Team This is an educational overview of published research, not medical advice. MOTS-c is a short peptide linked to mitochondrial genetic material. Cell and animal studies explore how it affects energy use and responses to stress. Published human findings mainly measure the body’s own

Semax: ACTH-Derived Peptide Research and Evidence Gaps

Back to Research Library Evidence reviewed: 21 August 2026Author: ExtolX Editorial Team This is an educational overview of published research, not medical advice. Semax is a laboratory-made peptide based on a small part of the natural hormone ACTH. Researchers have studied it in cells, animals and some regional clinical settings, but the accessible human evidence

Selank: Tuftsin-Derived Peptide Research and Human Evidence

Back to Research Library Evidence reviewed: 21 August 2026Author: ExtolX Editorial Team This is an educational overview of published research, not medical advice. Selank is a laboratory-made peptide derived from tuftsin, a natural immune-system peptide. Most published work examines signalling and behaviour in laboratory or animal models; the available human research is too limited to

Melanotan II: Melanocortin Biology, Early Human Studies and Safety Questions

Back to Research Library Evidence reviewed: 31 October 2026Author: ExtolX Editorial Team This is an educational overview of published research, not medical advice. Melanotan II is a laboratory-made peptide based on alpha-melanocyte-stimulating hormone. Early human studies reported biological effects, but they were small and also recorded unwanted effects. They do not provide a complete account

NAD+: Cellular Cofactor, Metabolism and the Human Research Landscape

Back to Research Library Evidence reviewed: 31 October 2026Author: ExtolX Editorial Team This is an educational overview of published research, not medical advice. NAD+ is a molecule that cells use in energy transfer and enzyme reactions. It is not a peptide. Although human studies have tested NAD+-related precursors such as NR and NMN, direct NAD+

Glow Peptide Blend Explained: GHK-Cu, BPC-157 and TB-500 Research

Back to Research Library Evidence reviewed: 31 October 2026Author: ExtolX Editorial Team This is an educational overview of published research, not medical advice. Glow is a research blend containing GHK-Cu, BPC-157 and TB-500. Each component has its own evidence base, but combining them creates a new mixture whose stability and biological behaviour must be tested
