Purity (active PDRN substance)
G_PURITYWhat does this word mean?
The purity of the active PDRN substance, which reaches above 95% for salmon-derived material.
Expanded note
High purity is a key metric for reducing immunogenic side effects and is one reason salmon-derived material became the industry standard. The site never infers purity for any product and only records brand-stated concentrations, always labelled as claimed rather than measured.
Not a generic example.
PMID 39486723 describes a highly pure active substance above 95%.
