Crystagen (EDP)
Preclinical
Research chemical
Summary
Khavinson immune/thymus-focused short peptide bioregulator commonly cited as Glu-Asp-Pro (EDP), positioned as a synthetic counterpart within the thymic bioregulator family alongside Thymalin.
Categories
Immune, Longevity
Mechanism
Proposed tissue-selective epigenetic regulation of thymic and immune cell gene expression. Organotypic spleen studies associate EDP with B-cell compartment activation; observational clinical descriptions claim normalized CD4/CD8 ratios and reduced infection frequency in aging cohorts (single-group literature quality).
Half-life
Short (tripeptide)
Routes
Subcutaneous injection; Oral
Legal / access
Research bioregulator; not FDA-approved for immune deficiency or infection prevention.
Key risks
- Limited Western RCT data
- Theoretical immune stimulation concerns in autoimmunity
Common claims
- Immune resilience
- Thymic support
- Infection-frequency narratives in bioregulator communities
