Culture and controversy
Culture and controversy: 11 articles from Peptidesfact. Long-form reporting on peptide science.
How Oxytocin Became the Love Hormone
A nine-amino-acid hormone of childbirth, two species of vole, one famous nasal-spray experiment and a bestselling book. How a molecule acquired a reputation, and what happened when other scientists went back to check it.
The Hormone That Was Supposed to Cure Autism
In 1998 a 1902 digestive hormone became, for a few months, the most talked-about idea in the autism community. The anatomy of a claim: a small report, a television programme, a shortage, the trials that followed, and the review that closed the file.
How a Word From Biochemistry Became a Hashtag
For a century the word sat on order forms and in textbooks, naming a size of molecule and nothing more. Then it borrowed the fame of two medicines and found a medium built for words that sound exact and promise everything.
Natural, Synthetic, and the Marketing In Between
Two chromatograms laid one over the other, peak for peak, and no way to tell which molecule came from a living cell and which from a machine. The words on the label insist there is a difference. The molecule does not.
The Biohacker and the Regulator
Medicine keeps a hall of fame for people who experimented on themselves. Medicines law was never written with them in mind. In 2026 the two finally met, and the meeting took place at a clinic and a pharmacy rather than in anyone's kitchen.
The Longevity Industry and Its Favourite Molecules
The menus are printed on heavy card and the vocabulary is scrupulous: support, optimise, cellular health. The evidence behind the molecules on them is a good deal thinner than the paper, and the care taken over the words is part of the story.
When an Athlete Tests Positive for a Peptide
A urine sample collected at a rugby league training ground in December 2014 was analysed, found clean and put into storage. Six years later somebody took it out again. What a peptide case proves, and how often one begins without a positive test at all.
What Is Actually in the Vial
A label is a claim, and for most of this market nobody independent has ever checked it. A handful of analytical chemists have — and what they found is a different problem from the one everyone argues about.
How Skincare Borrowed the Word Peptide
The word is on jars at every price, almost never with a concentration, a study or a specific molecule attached. What it is doing there turns out to be a question about law as much as about chemistry.
Why the Claims Outrun the Evidence
A compound can gather a couple of hundred papers reporting benefit and still have never been given to a single person under controlled conditions. The distance between those two facts is not the work of liars — it is built into the way findings travel.
Testing for a Molecule the Body Already Makes
Anti-doping chemistry usually asks a simple question: is this foreign substance here or not? Peptides refuse to answer it, because most of them are not foreign at all.
