- HandlingWhere the 28 days number comes from (it is not peptide data)The 28-day figure often attached to peptides is a pharmacy standard for preserved multi-entry containers, tied to a 28-day microbiology test. It measures preservative performance, not what happens to a peptide in solution.
- How it is madeWhy a factory-made peptide spray differs from a vialWhat a formulated aqueous peptide product contains (buffer, tonicity agent, preservative), how preservative efficacy is tested under USP <51>, why formulated products carry an in-use period, and what a dissolving strip is made of.
