RS BIO LABS

“Peptides are some of the most exciting compounds in biology right now. The research coming out is extraordinary — we’re talking about molecules that interact with the body’s own signalling systems in ways that were barely understood a decade ago.”

— Dr. Andrew Huberman, Neuroscientist & Host, Huberman Lab Podcast

Peptides are one of the fastest-growing areas in biochemical research. The clinical trial data is striking — and it’s no longer niche. RS Bio Labs supplies ≥99% purity, HPLC-verified research compounds with a Certificate of Analysis on every order. These are not FDA or MHRA approved for human use. They are sold strictly for research purposes. Make of the science what you will.

MOTS-C
Mitochondrial-Derived Peptide · 40mg

MOTS-C is a 16-amino acid peptide encoded within the mitochondrial genome, discovered in 2015 by Lee et al. in Cell Metabolism. Classified as a mitokine, it circulates systemically and acts on nuclear gene expression — a discovery that fundamentally expanded understanding of mitochondria beyond energy production. Circulating MOTS-C rises with exercise and declines with age, making it a central subject in metabolic and longevity biology research.

AMPK Activation & Metabolic Research: MOTS-C activates AMPK via the AICAR pathway in skeletal muscle, promoting GLUT4-mediated glucose uptake independent of insulin signalling. The discovery paper (Lee et al., Cell Metabolism 2015) demonstrated reversal of diet-induced obesity and insulin resistance in preclinical models.
Ageing & Longevity Studies: A 2021 Nature Communications study (Reynolds et al., N=mouse cohorts across three age groups) showed MOTS-C-treated groups demonstrated differences in physical capacity measures across young, middle-aged, and old subjects. MOTS-C gene polymorphisms have also been associated with human longevity in genetic epidemiology data.
Pancreatic & Metabolic Research: Nature 2025 data showed MOTS-C prevents β-cell senescence via AMPK/mTOR pathway modulation in diabetic mouse models, with measurable differences in pancreatic islet senescence markers and glucose handling.
Cardiovascular Pathway Research: Preclinical cardiac studies (Frontiers in Physiology, 2025) in T2D rat models reported differences in mitochondrial respiration markers, fasted blood glucose levels, and left ventricular wall thickness measurements in MOTS-C-treated groups versus controls.
