What happens to a peptide each time a vial is frozen, thawed and drawn from again — and why “looks the same” on the label isn’t the same as “is the same” in solution.

From a synthetic fragment modelled on a gastric-protective protein to one of the most discussed compounds in longevity research.

What is HPLC testing, and why is the purity number the one that decides whether a research peptide is real? A plain-English guide to how peptides are separated, measured and verified.

How do you know a Certificate of Analysis can be trusted? A plain-English guide to batch-matching, testing methods, independence versus accountability, and how to check any COA in minutes.

The Research Edit 6 min read By the OP Labs editorial team A molecule only a few amino acids long, reaching toward neurons, muscle, skin and mitochondria at once — and a field still working out which of those reaches actually lands. Abstract peptide molecular network — an illustration of the open questions in current […]

How do scientists discover new peptides? Genome mining, phage display, mass spectrometry and AI design — an educational guide for researchers, cited throughout.

Research Overview 19 May 2026 11 min read By the OP Labs editorial team It circulates in human plasma right now — a tiny three-amino-acid molecule that researchers believe may play a far larger role than its size would suggest. Illustrative rendering of a copper tripeptide in solution. OP Labs · Research Key facts at […]

Cellular Energy 11 min read By the OP Labs editorial team By the age of fifty, research suggests human tissues may hold substantially less NAD+ than at twenty — and scientists are still working out exactly what that means. Abstract visualisation of mitochondrial energy production. OP Labs · Research NAD+ is not a household name, […]

History 10 min read By the OP Labs editorial team In 1921, a young surgeon with no research funding and a half-formed idea walked into a university laboratory and changed medicine forever. A century of peptide discovery, told through its turning points. OP Labs · Research His name was Frederick Banting. He was not a […]

Fundamentals 8 min read By the OP Labs editorial team They are all made from the same twenty building blocks — so why do scientists treat them as completely different things? Amino acid, peptide, protein — one continuous chemistry, three behaviours. OP Labs · Research It is a fair question, and a common source of […]
