Testing & quality
Sterility
The absence of viable microorganisms — a requirement for anything injected, tested separately from purity and identity.
In plain terms
A peptide can be pure, correctly identified, and non-sterile. Sterility depends on how the material was handled and filled, not on how cleanly it was synthesised.
