Peptide Half-Life Explained: Why Half-Lives Differ Between Peptides

Research use disclaimer: The compounds discussed below are sold by Crown Peptides for laboratory research use only and are not intended for human consumption. Ask ten people how long a peptide “lasts” and you’ll get ten different answers — because the honest answer is that it depends entirely on which peptide you’re holding. Some research […]

NAD+ vs MOTS-c: Two Roads Into Mitochondrial Research

Two of the most talked-about compounds in mitochondrial research right now don’t even work the same way. One is a molecule your cells have relied on since the origin of life itself. The other is a sixteen-amino-acid fragment that hid inside human DNA for decades before anyone realised it was a peptide at all. Researchers […]

GHK-Cu vs Glutathione: Two Tripeptides, Two Completely Different Skin Mechanisms

GHK-Cu vs Glutathione: Two Tripeptides, Two Completely Different Skin Mechanisms On paper, GHK-Cu and glutathione look like twins. Both are tripeptides, just three amino acids long. Both occur naturally in the human body. Both decline with age in ways researchers find interesting. And both turn up again and again in skin research, which is why […]

Three Compounds, One Skin Axis: The Dermal & Cellular Bundle

A tripeptide pulled from human blood plasma in 1973. A three-residue fragment sliced off the back end of a pigmentation hormone. A molecule so central to cellular survival that nearly every living cell on Earth manufactures its own supply. None of these three compounds were built for skin research. All three ended up there anyway, […]

Three Peptides, One Gut Axis: The Gastrointestinal Bundle

Three Peptides, One Gut Axis: The Gastrointestinal Bundle Picture three peptides that never appear in the same textbook chapter, arrived at by three completely different research paths, and yet all end up circling the same eleven metres of intestine. One is a three-amino-acid fragment left over when researchers trimmed a hormone down to its most […]

Three Peptides, One Immune Axis: The Immune Pathway Bundle

Three Peptides, One Immune Axis: The Immune Pathway Bundle Ask ten immunologists what “boosting the immune system” actually means and you’ll get ten different answers — because the immune system isn’t one system, it’s several overlapping ones, and most allergy or inflammation research picks a single corner of it to study at a time: histamine […]

Three Peptides, One Metabolic Pathway: The Metabolic Bundle

Three Peptides, One Metabolic Pathway: The Metabolic Bundle Most compounds researched for metabolic effects attack the problem from a single angle. Push more energy through the mitochondria, or block the enzyme that tells fat cells to keep growing, or trigger fat breakdown directly — pick one mechanism and hope it’s enough. The Metabolic Research Bundle […]

Pinealon: The Three-Amino-Acid Peptide That Talks Directly to Neuronal DNA

Pinealon: The Three-Amino-Acid Peptide That Talks Directly to Neuronal DNA Most signalling molecules in the body work like someone ringing a doorbell. A hormone arrives at the outside of a cell, presses a receptor, and a relay of messages carries the news inward until, eventually, something in the nucleus changes. Pinealon, according to the scientists […]

GHRP-2: The Growth Hormone Secretagogue That Became a Diagnostic Drug

GHRP-2: The Growth Hormone Secretagogue That Became a Diagnostic Drug Most research peptides live their whole lives in laboratories. GHRP-2 escaped. A molecule that started as a curiosity in an American endocrinology lab ended up in hospital clinics in Japan, where doctors use it to answer one of the trickiest questions in hormone medicine: is […]

Why Glutathione Is Known as the Body’s Master Antioxidant

Why Glutathione Is Known as the Body’s Master Antioxidant Vitamin C gets the headlines. Vitamin E gets the supplement aisle. But inside almost every cell in your body, the antioxidant doing most of the heavy lifting is a molecule most people have never heard of until recently: a tiny three-amino-acid peptide called glutathione. It is […]
