Side-by-side comparison of key properties, dosing, and research.

Anti-Aging & Longevity
Ovagen
Immune SupportRecovery & Repair
LL-37
Summary
Ovagen is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, primarily targeting liver tissue. It supports hepatocyte function, liver cell regeneration, and protection against hepatic aging and disease. Ovagen is used in protocols for chronic liver disease, hepatoprotection, and metabolic liver conditions including fatty liver disease.
LL-37 is the only known human cathelicidin antimicrobial peptide. It kills bacteria, fungi, and viruses by disrupting their membranes, while simultaneously modulating immune responses. Used for antimicrobial protection, immune priming, and wound healing.
Half-Life
Short (minutes); sustained gene-regulatory effects
Very short (~1–2 hours) in plasma due to protease degradation; topical use bypasses systemic clearance
Admin Route
SubQ, Oral
SubQ, Topical, Intranasal
Research
Typical Dose
10 mg per day
100–300 mcg
Frequency
Daily for 10–30 days
2–3x per week
