Maximin vs PR-39

Maximin vs PR-39 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Maximin
Antimicrobial Peptide

Maximins are a large and diverse family of antimicrobial and neuroactive peptides isolated from the skin and brain of the Chinese firebelly toad Bombina maxima. Maximins are notable for containing D-amino acid residues in specific positions, a rare post-translational modification...

PR-39
Antimicrobial Peptide

PR-39 is a 39-residue proline- and arginine-rich antimicrobial peptide from porcine neutrophil granules. Unlike classical membrane-disrupting AMPs, PR-39 kills bacteria intracellularly by inhibiting DNA and protein synthesis....
