G_PDRNWhat does this word mean?
A mixture of DNA fragments with a molecular weight of 50-1500 kDa whose primary mechanism is activation of the adenosine A2A receptor pathway.
Expanded note
PDRN was first isolated from human placenta for pharmaceutical development in Italy. Today the mainstream source is DNA purified from salmon or trout sperm at a purity above 95%. Ingredient lists do not say PDRN; they say Sodium DNA or Hydrolyzed DNA.
Not a generic example.
The site product database holds 644 PDRN-containing products, registered mainly as Sodium DNA across 95 name variants.
