Overview

Crystagen is described in the bioregulator literature as a short synthetic immune-oriented peptide, positioned as a general immune-system regulator within the Khavinson framework. It is discussed for proposed effects on immune-cell activity and immune balance during aging, overlapping conceptually with the thymic bioregulators. The supporting evidence is largely in-house, older, and non-Western, and independent replication in mainstream immunology is lacking.

How it’s thought to work

  • Proposed to act as an immune-oriented peptide bioregulator influencing gene expression in immune cells.
  • Studied for effects on immune-cell activity and cytokine-related markers.
  • Mechanistic claims rest largely on the originating group's work and are not independently well established.

Researched uses

  • Immune support in aging models
  • General immune-balance research interest
  • Cited in longevity-peptide and immune-function discussions

Reconstitution

Commonly a 5-10 mg vial; reconstitute with bacteriostatic water and use the calculator for units.

Crystagen dosage calculator

The calculator below is pre-filled with Crystagen’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.

How much water you add is your choice — it doesn’t change your dose, only how many units you draw. Common:

Doses per vial

📋 In plain English

Add 2 mL of bacteriostatic water to your 10 mg vial. That gives you about 5 doses of 2 mg. For each dose, draw 40 units into a 100-unit insulin syringe.

Cautions

  • Not FDA-approved; a research compound, not an approved immune therapy.
  • The evidence base is limited, older, and largely non-Western, and has not been widely replicated.
  • Purity of research-grade material varies by source.
  • Immune conditions should be managed with a qualified clinician rather than self-directed peptide use.
