What Is RTN?
RTN is a collection of historically used tissue-based formulations, originally developed in Czechoslovakia in the 1940s. Administered in clinical settings to support oncology care, inflammation control, and tissue regeneration, these compounds are now being reintroduced under modern scientific and regulatory standards.
Our Mission
To bring validated, naturally derived compounds back into evidence-based healthcare—revitalizing decades of historical data with modern preclinical science to confirm their efficacy, safety, and relevance for today’s world.
Historical Context
1940s
RTN preparations used in over 12,000 documented hospital cases across Czechoslovakia.
1950s–1970s
State-approved and manufactured for national health programs.
Post-1980s
Phased out due to synthetic pharmaceutical dominance, despite continued institutional support.
Today
Scientific revival via EkoRTN, applying rigorous modern validation and regulatory compliance.
RTN Preparations
Retisin
A nucleotide extract derived from bovine tissue, rich in ATP precursors (AMP, GMP, CMP). Supports cellular energy production and regeneration.
Lyastin
Phospholipid complex promoting vasodilation, nerve regeneration, and cellular membrane repair. Originally developed for frostbite, gangrene, and circulatory disorders.
Floristen
Water-soluble extract of St. John’s Wort, purified for anti-inflammatory and antioxidant properties. Historical applications in gynecology, inflammation, and systemic oxidative stress.
Silexil
Marine-derived preparation aimed at joint support, pain relief, and anti-inflammatory function. (in redevelopment)
Scientific Approach
All current formulations are undergoing controlled preclinical validation aligned with EU and international dietary supplement safety standards.
Real-Time Monitoring
Custom sensors, open-source platforms, and secure digital infrastructure support continuous production monitoring for needed quality.
Data-Driven Development
Our diagnostics platform uses structured biomarker data collection to inform product optimization and individual response tracking.
Personalization Protocol
We match preparations to individuals based on advanced diagnostic panels. These include inflammation markers, lipid profiles, immune response indicators, and more.
Ethical AI Integration
We use AI tools to interpret complex biomarker data—these are designed to assist clinicians, not replace them. No magic, no hype.
Strategic Goals
Partnerships
Expanding our network with certified clinical and academic institutions to accelerate validation efforts.
Clinical Validation
Initiating Phase I trials with verified RTN preparations to establish safety profiles and preliminary efficacy data.
Scientific Publication
Documenting results in peer-reviewed journals to build credibility within the scientific community.
API Status
Securing regulatory recognition through rigorous documentation and compliance with FDA, EMA and Thai FDA authorities.
