Few molecules in cellular biology have attracted as much sustained research attention over the past decade as NAD+ (nicotinamide adenine dinucleotide). It sits at the centre of energy metabolism, DNA repair signalling, and a family of enzymes implicated in ageing biology, which is exactly why it shows up so often in both serious research literature and considerably less rigorous wellness marketing. This guide sets out what NAD+ actually does at the cellular level, what recent

A peptide’s behaviour in the lab is only ever as good as how it was handled before it got there. A vial that shipped at 99%+ purity, backed by a clean COA, can lose meaningful activity within weeks if it’s stored or reconstituted carelessly, often without any visible sign that anything has changed. This guide covers what’s actually happening to a peptide in storage, how to reconstitute it correctly, and the handling habits that quietly cause degradation before a compound is e

A peptide COA contains important information about a product’s identity, purity, and quality. Learn how to understand HPLC results, mass spec data, and other key details before evaluating a batch.
