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.
Animal studies: Only in-vitro work: cultured lymphocytes from elderly donors (chromatin changes) and rat organotypic tissue explants at 0.05 ng/ml; no whole-animal or prostate studies.
No animal or human studies of prostate effects were found. Concentrations used in cell culture do not translate to doses in people.
What the research says
Prostamax (Lys-Glu-Asp-Pro) is a 'peptide bioregulator' marketed for the prostate, but PubMed holds only a few cell-culture and biophysics studies on chromatin in white blood cells from elderly donors and a rat tissue-explant study; there are no studies of prostate function in animals or humans. One added lymphocyte-culture study (2009) reports effects of copper and cadmium on chromatin but not a clear prostamax result.
Key papers ? 5

[Deheterochromatinization of the chromatin in old age induced by oligopeptide bioregulator (Lys-Glu-Asp-Pro)].Cells / labIn vitro cytogenetic study of Prostamax (Lys-Glu-Asp-Pro) on chromosomes
In lymphocytes from people aged 75-86, Prostamax doubled the sister-chromatid exchange rate (12.0 vs 5.9 per cell) and increased active ribosomal-gene regions, interpreted by the authors as chromatin 'decondensation'.
Key resultSister chromatid exchanges rose to 12.0 +/- 0.28 per cell (5.9 +/- 0.2 in intact cells); Ag-positive NORs rose to 2.5 per cell (0.95 in intact cells)
Study details
- Studied
- Cells from old individuals (75-86 years)
- Compared with
- Intact (untreated) cells
- Main outcome
- Sister chromatid exchange, Ag-positive NORs, pericentromeric heterochromatin
- Sample
- Number of donors not stated; cells from individuals aged 75-86
- Authors' conclusion
- The authors interpret the changes as Prostamax decondensing the chromatin during aging and releasing repressed genes, suggesting a protective chromatin-modifying effect.
- Limitations
- In vitro cell study; interpretation of chromatin changes as beneficial is speculative; no clinical outcome.
-
Effects of short peptides on lymphocyte chromatin in senile subjects.Cells / labIn vitro study of five short peptides (Vilon, Epithalon, Livagen, Prostamax, Cortagen) on chromatin
In white blood cells from people aged 75-88, Prostamax and other short peptides activated ribosomal genes and decondensed chromatin.
Study details
- Studied
- Leukocytes from subjects aged 75-88 years
- Compared with
- Untreated cells
- Main outcome
- Ribosome gene activity and chromatin condensation
- Sample
- Number of subjects not stated; leukocytes from subjects aged 75-88
- Authors' conclusion
- All peptides activated ribosome genes and decondensed chromatin; Epithalon, Livagen and Prostamax decondensed chromosome 1 pericentromeric chromatin.
- Limitations
- In vitro; not specific to Prostamax; no clinical outcome.
-
[The influence of the peptide bioregulator prostamax on heterochromatin of human lymphocytes in situ].Cells / labCalorimetric (denaturation) study of lymphocyte chromatin treated with Prostamax
Calorimetry of human lymphocytes showed Prostamax caused small shifts in chromatin denaturation, suggested to reflect partial relaxation of chromatin fibres.
Key resultProstamax shifted endotherms Td III and Td IV to lower temperatures by 2.9 and 1.0 degrees C
Study details
- Studied
- Human lymphocytes
- Compared with
- Untreated lymphocytes
- Main outcome
- Chromatin denaturation endotherms
- Authors' conclusion
- The authors suppose the changes reflect partial relaxation of the 30-nm fiber and small structural changes in nucleosomal organization.
- Limitations
- In vitro biophysical study; interpretation is speculative.
-
[The tissue-specific effect of synthetic peptides-biologic regulators in organotypic tissues culture in young and old rats].Cells / labOrganotypic tissue culture with cardiogen, bronchogen, prostamax and pancragen at 0.05 ng/ml
In organ-explant cultures from young and old rats, Prostamax (with cardiogen, bronchogen and pancragen) stimulated growth of the matching tissue (prostate).
Study details
- Studied
- Organotypic explants of heart, lung, prostate and pancreas from young (3-week) and aged (18-month) rats
- Compared with
- Control explants
- Main outcome
- Tissue-specific explant growth
- Authors' conclusion
- At 0.05 ng/ml each peptide stimulated growth in its matching tissue culture compared with controls, so the authors suggest the peptides could stimulate reparative processes in ageing tissues.
- Limitations
- Explant cultures only; no numerical data in the abstract.

Microcalorimetric study of human blood lymphocytes culture at presence of copper, cadmium and prostamax.Cells / labMicrocalorimetry of chromatin denaturation with prostamax, Cu(II) and Cd(II)
Lymphocyte cultures from elderly donors: study of prostamax alone and with Cu(II)/Cd(II) ions on chromatin; the abstract reports effects of the metal ions (Cu condensed, Cd decondensed heterochromatin) but not the result for prostamax itself.
Study details
- Studied
- Blood lymphocyte cultures from aging people
- Main outcome
- Thermal stability / heterochromatin condensation
- Authors' conclusion
- Cu(II) caused additional heterochromatin condensation and Cd(II) caused decondensation and partial denaturation; the abstract does not state the effect of prostamax.
- Limitations
- Cell study; the prostamax result is not given in the abstract.

Prostamax: questions people ask
What is Prostamax?
Russian short-peptide bioregulator. One of the Khavinson "bioregulator" peptides from Russian aging research, marketed for the prostate. Evidence comes mainly from Russian cell and animal studies.
How much does Prostamax cost?
The cheapest Prostamax from an independently tested vendor is $0.475 per mg (Andy Peps Studio, MAX20 Prostamax 20mg * 10 vials, $95.00). Across 19 listings from 18 vendors the median is $2.20 per mg.
Where can I buy Prostamax?
18 vendors tested by Finnrick sell Prostamax. The cheapest per mg right now: Andy Peps Studio ($0.475), Baohua Dongnuo Biotechnology BHD ($0.475), LN Peptides ($0.475). 4 of them publish a lab report (COA) for Prostamax; compare lab scores and reports in the table above before buying.
How much bacteriostatic water for 20 mg of Prostamax?
Adding 2 mL of bacteriostatic water to a 20 mg vial of Prostamax 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 Prostamax FDA approved?
Sold as a supplement in Russia; not approved in the US. Research use only.
Can Prostamax 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 Prostamax work? What does the research say?
Evidence grade D (little or no evidence), from 5 papers: Only cell-culture, chromatin biophysics and tissue-explant studies; no animal or human studies of prostate function. Prostamax (Lys-Glu-Asp-Pro) is a 'peptide bioregulator' marketed for the prostate, but PubMed holds only a few cell-culture and biophysics studies on chromatin in white blood cells from elderly donors and a rat tissue-explant study; there are no studies of prostate function in animals or humans. One added lymphocyte-culture study (2009) reports effects of copper and cadmium on chromatin but not a clear prostamax result. See the papers.
What dose of Prostamax was used in studies?
Prostamax is tested only in animals or cells. Only in-vitro work: cultured lymphocytes from elderly donors (chromatin changes) and rat organotypic tissue explants at 0.05 ng/ml; no whole-animal or prostate studies. These are amounts used in published studies or official labels, not a recommendation.
