Library
Educational articles written in plain language, covering the science and vocabulary that recur throughout peptide research.
Fundamentals
A plain-language introduction to what peptides are, how they differ from proteins, and why they have become a major focus of biomedical research.
Metabolic
GLP-1, GIP and glucagon receptor agonists have dominated metabolic research for a decade. Here is what the receptor names actually mean.
Research Methods
From cell culture to phase 3 trials — how to read the evidence hierarchy and judge how strong a peptide's research base really is.
Handling
Why research peptides arrive as powder, what bacteriostatic water does, and how concentration determines every number downstream.
Handling
Temperature, light and time are the three variables that determine how long a peptide stays intact. Here is what the stability literature says.
Fundamentals
Half-life, bioavailability, agonist, analogue, lyophilised — a glossary of the terms that recur throughout peptide literature.
