The handling questions we get asked most, answered properly. Technique, storage and analytical chemistry — no dosing guidance, because these are research materials and we do not provide it.
How to reconstitute a peptide without ruining it
Why you run the diluent down the vial wall instead of straight onto the powder, why you never shake, and what the foam actually means.
Storage, stability and how long a vial really lasts
Lyophilised versus reconstituted, why bacteriostatic water changes the answer, and the degradation routes that actually matter.
What "99% purity" does and does not tell you
How HPLC purity is calculated, why mass spectrometry is the more important number, and the gap between peak-area purity and peptide content.

Concentration, volume to draw, and the answer in units on a U-40 or U-100 insulin syringe — with a to-scale barrel diagram.
