Doses studied in research Animal or lab studies only
What was given to people (or animals) in published studies and official labels, each linked to its source. This is not a recommendation: study products, purity and supervision differ from research-grade vials.
The only published mention found is a review of spleen ageing reporting that Crystagen activates B cells (PMID 28976144); no dose, concentration or schedule is given in any PubMed abstract, and no human studies were found.
What the research says
Crystagen (reported as the peptide Glu-Asp-Pro) has almost no published literature. One Russian review of spleen ageing reports that it activates B cells without renewing spleen cells; nothing else directly tests it. There are no human studies.

[Molecular aspects of immunoprotective activity of peptides in spleen during the ageing process].No new dataReview
A review of spleen ageing reports that Crystagen activates B cells but, unlike the comparator peptides Vilon and R-1, does not drive cell renewal in the ageing spleen; no quantitative or clinical data are given.
Study details
- Studied
- Spleen immune cells during ageing (review of peptide effects including Vilon, Timogen, Crystagen, R-1)
- Main outcome
- Immunoprotective effects of short peptides in the spleen
- Authors' conclusion
- Crystagen activates B-cells of the immune system but does not cause cell renewal in the spleen as it ages, unlike some of the other peptides reviewed.
- Limitations
- Review of the authors' group's work; no numbers in abstract.
Reported side effects
No human studies and no human safety data; the compound is essentially unstudied in the published literature.

Crystagen: questions people ask
What is Crystagen?
Russian short-peptide bioregulator. One of the Khavinson "bioregulator" peptides from Russian aging research. Evidence comes mainly from Russian cell and animal studies.
How much does Crystagen cost?
The cheapest Crystagen from an independently tested vendor is $0.475 per mg (Andy Peps Studio, CRY20 Crystagen 20mg * 10 vials, $95.00). Across 11 listings from 10 vendors the median is $1.13 per mg.
Where can I buy Crystagen?
10 vendors tested by Finnrick sell Crystagen. The cheapest per mg right now: Andy Peps Studio ($0.475), Baohua Dongnuo Biotechnology BHD ($0.475), LN Peptides ($0.475). 0 of them publish a lab report (COA) for Crystagen; compare lab scores and reports in the table above before buying.
How much bacteriostatic water for 20 mg of Crystagen?
Adding 2 mL of bacteriostatic water to a 20 mg vial of Crystagen gives 10 mg/mL: each 10 units on a U-100 insulin syringe holds 1,000 mcg. With 1 mL it's 20 mg/mL (2,000 mcg per 10 units); with 3 mL, 6.667 mg/mL (666.7 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 20 mg.
Is Crystagen FDA approved?
Sold as a supplement in Russia; not approved in the US. Research use only.
Can Crystagen be compounded in the US?
Not an FDA-approved drug and not nominated for FDA's 503A bulks list, so US pharmacies can't legally compound it. Compounding status for every peptide.
Does Crystagen work? What does the research say?
Evidence grade D (little or no evidence), from 1 papers: Essentially nothing: a single Russian review mentions B-cell effects with no data; no animal or human studies. Crystagen (reported as the peptide Glu-Asp-Pro) has almost no published literature. One Russian review of spleen ageing reports that it activates B cells without renewing spleen cells; nothing else directly tests it. There are no human studies. See the papers.
What dose of Crystagen was used in studies?
Crystagen is tested only in animals or cells. These are amounts used in published studies or official labels, not a recommendation.
