Crystagen 20mg
Synthetic tripeptide bioregulator (Glu-Asp-Pro) studied in Khavinson models for immune system modulation and cellular gene expression.
Mechanism
Hypothesized to penetrate cellular structures to modulate gene expression and transcription factors governing thymic and immune cell function.
Dosing
Standard laboratory protocols document an initial administration level of 1,000 mcg once daily, titrating up to 2,000 mcg daily.
Reconstitution
Adding 3.0 mL of bacteriostatic water to a 20 mg vial yields an operational concentration of approximately 6.67 mg/mL (6,667 mcg/mL).
Storage
Store the lyophilized vial at -20 °C protected from light, and keep the reconstituted liquid refrigerated between 2 °C and 8 °C for up to 28 days without freezing.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Week 1 | 1,000 mcg (1× daily) | ~15 units (0.15 mL) |
| Week 2 | 1,500 mcg (1× daily) | ~22.5 units (0.225 mL) |
| Weeks 3–12 | 2,000 mcg (1× daily) | ~30 units (0.30 mL) |
Reconstitution Steps
- 1
Sanitize the rubber stoppers of both the bacteriostatic water and the Crystagen vial using separate sterile alcohol pads.
- 2
Draw 3.0 mL of bacteriostatic water using an appropriately sized sterile syringe.
- 3
Insert the syringe needle into the Crystagen vial and slowly run the diluent down the inside glass wall to prevent excessive foaming.
- 4
Gently swirl and roll the vial between your palms until the lyophilized powder is completely dissolved, avoiding vigorous shaking.
- 5
Record the date, time, and concentration on the vial label and place it immediately into refrigerated storage at 2–8 °C.

Overview
Crystagen is a synthetic short-chain peptide bioregulator consisting of the tripeptide sequence glutamic acid, aspartic acid, and proline (Glu-Asp-Pro or EDP). Formulated as the targeted cytogen analog to bioactive compounds historically isolated from bovine thymus extract (Thymalin), it belongs to the Khavinson class of regulatory peptides. In preclinical research models, short bioregulatory peptides are evaluated for their potential to interact directly with nucleosomal DNA and histones to influence epigenetic transcription without hormonal receptor activation. Investigational studies primarily center around immune signaling pathways, immunosenescence, and cellular resilience during physiological stress. Because Crystagen remains an investigational research agent without therapeutic approval by regulatory authorities, laboratory handling requires precise sterile preparation, controlled reconstitution, and adherence to established reference dilutions to ensure accurate analytical results.
