Third-party tested.
Quality made clear.
Peptyde compounds are evaluated by independent laboratories for identity and purity. It is a quality standard built into the catalog—not an extra step in the buying experience.
See how we testIdentity
Third-party analysis helps confirm that each tested compound matches its stated identity.
Purity
Independent HPLC testing measures purity within the tested sample.
Independent labs
Testing is performed outside Peptyde by third-party analytical laboratories.
Quality control
Testing, handling, and fulfillment standards work together across the catalog.
The researchers behind peptide science.
Meet researchers whose published work helped define MOTS-c, SS-31, and glucagon-like peptide biology.
Leonard Davis School of Gerontology
Pinchas Cohen, MD
Distinguished Professor and Dean
MOTS-c · Mitochondrial-derived peptides
“MOTS-c treatment in mice prevented age-dependent and high-fat-diet-induced insulin resistance, as well as diet-induced obesity.”
Weill Cornell Medicine
Hazel H. Szeto, MD, PhD
Pharmacologist and peptide researcher
SS-31 · Mitochondrial peptide biology
“SS-31 is a mitochondria-targeted tetrapeptide that can scavenge mitochondrial ROS and inhibit MPT, suggesting that it may protect against ischemic renal injury.”
University of Toronto · Sinai Health
Daniel J. Drucker, MD
University Professor and clinician-scientist
GLP-1 and GLP-2 · Regulatory peptides
“Glucagon-like peptide-1 (GLP-1) released from gut enteroendocrine cells controls meal-related glycemic excursions through augmentation of insulin and inhibition of glucagon secretion.”
University of Copenhagen
Jens Juul Holst, MD, DMSc
Professor of Medical Physiology
GIP and GLP-1 · Incretin physiology
“The incretin effect … is one of the factors that help the body to tolerate carbohydrate/glucose ingestion.”
