KPV peptide explained in plain English: what this three-amino-acid fragment of alpha-MSH is, how researchers think it works, and what cell and animal studies have reported.
Peptide hormones explained in plain English: what they are, how the body makes them, how they act on cells, how they differ from steroid hormones, with examples such as insulin, oxytocin and ghrelin.
Endotoxin testing explained in plain English: what endotoxin is, how the LAL test works, why it matters in peptide research and how to check for it on a certificate of analysis.
AHK-Cu vs GHK-Cu explained in plain English: how the two copper peptides differ in sequence, copper binding, origin and published research, with a side-by-side table.
What are the different types of peptides? A plain-English UK guide to dipeptides, tripeptides, oligopeptides, cyclic peptides, peptide hormones and more, with real examples.
What is in a peptide vial? A plain-English UK buyer’s guide to peptide vial sizes, mg vs mL, lyophilised powder, peptide content and what to check on arrival.
Are peptides natural? Many are made by the body or released from food, but research peptides are made in a lab. A plain-English guide to natural vs synthetic peptides.
Peptides vs proteins in plain English: both are chains of amino acids, but peptides are short and flexible while proteins are long, folded chains. Examples and a quick table.
How are peptides made? A plain-English guide to peptide synthesis: how solid-phase synthesis builds a chain one amino acid at a time, then purification and testing.
