Molecular weight (kDa and Da)
G_MWWhat does this word mean?
A measure of the mass of a polymer or molecule, central to how PDRN is characterised and why it struggles with transdermal delivery.
Expanded note
The site presents molecular weight in three layers: the overall 50-1500 kDa range for commercial forms, the 80-200 kDa band where activity concentrates, and the fact that lower-molecular-weight fragments show better activity, uptake and penetration.
Not a generic example.
PMID 39486723 describes PDRN as a registered DNA-derived proprietary drug containing DNA fragments of molecular weights of 50 and 1500 kDa.

PDRN is not approved by the FDA for injection or any therapeutic use. Topical and injectable PDRN are parallel facts under different regulatory pathways and must not be directly equated.
PN is not PDRN. Evidence grades are labelled on every factual element; in vitro and animal research is never described as clinical efficacy.
