Oral
Crystagen has no standard bacteriostatic water volume on file, so there are no syringe units to calculate here. Dosing runs 20mg to 20mg per administration, daily. A 20mg supply covers about 1 dose at the beginner tier.
If your product does arrive as a powder, use the universal reconstitution calculator and enter your own vial size and water volume.
Crystagen is a synthetic thymus tripeptide from the Khavinson bioregulator program. Oral capsules (20 mg/day for 30 days) normalized immune markers in 82% of elderly patients in one Russian clinical observation. All published data comes from a single research group. No Western trials exist.

Crystagen comes as oral capsules, so there's no reconstitution math. Each capsule contains 20 mg of the synthetic tripeptide (Glu-Asp-Pro). Take one capsule 15 to 20 minutes before a meal, once daily, for 30 days. Swallow whole with water. The thing most beginners miss: you won't feel anything. Crystagen works through epigenetic changes in immune cells that accumulate over 15 to 30 days. Lack of immediate effect is normal, not a sign of a bad product. Bloodwork is the only way to know if it worked. Get a CBC with differential and CD4+/CD8+ ratio before starting, then retest four to six weeks after finishing the course. Subjective "feeling healthier" is unreliable for immune peptides. Source your capsules from Khavinson-affiliated vendors (CosmicNootropic, iPept, Antiaging Systems). Look for CYTOGENS branding with Russian-language primary labeling. Avoid injectable vials sold by research peptide vendors; that format has zero clinical backing.
