Description
Prostamax 20mg is a 20mg vial of Prostamax, a tetrapeptide bioregulator, made in the USA and supplied as freeze-dried powder. It’s sold for laboratory research only.
About Prostamax
It’s the tetrapeptide Lys-Glu-Asp-Pro, one of the short peptides linked in that program to prostate tissue. Its CAS number is 473578-47-1.
It comes from the bioregulator program led by Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, which proposed that very short peptides can bind DNA and switch particular genes on or off in specific tissues.
How Prostamax acts in the lab
Prostamax belongs to Khavinson’s family of tetrapeptide bioregulators, each linked to a specific tissue. The idea is that these short peptides bind DNA in that tissue’s cells and restore gene expression patterns that drift with age.
Most of the work is cell culture studies of prostate tissue cells, plus some rodent work.

Published Prostamax studies
Published work on it comes almost entirely from Khavinson’s group and other Russian labs, mostly cell culture studies of gene expression in prostate tissue cells, plus some rodent work.
Independent replication outside Russia is limited, so it’s best treated as an early-stage research peptide.

How Prostamax 20mg is tested
Every batch of Prostamax 20mg is made in the USA and checked by an independent U.S. lab for three things: that it’s the right compound, that the amount matches the label and that purity is 99% or better by HPLC.
You don’t have to take our word for it. The certificate of analysis for the current batch is in the image gallery at the top of this page, next to the product photo, and it shows the test date and the results.
On top of purity, each batch is screened for endotoxins, heavy metals and sterility. For cell culture work that screen is often the more important number.
How to reconstitute Prostamax 20mg
The amount of liquid you add sets the concentration. For a vial holding 20mg:
- 1mL of bacteriostatic water gives 20mg/mL
- 2mL of bacteriostatic water gives 10mg/mL
- 3mL of bacteriostatic water gives 6.67mg/mL
Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it. The vial itself holds 3mL, so that’s the upper limit.
Use sterile bacteriostatic water, like our 10mL bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll the vial gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.
Storing Prostamax 20mg
The dry powder keeps best cold. A freezer at -20°C is ideal for long-term storage, and a fridge works for a few weeks. After reconstitution, store it in the fridge and finish it within roughly four weeks.
If you keep several vials going at once, our 10 vial container keeps them upright and together on a fridge shelf, and spare 3mL vial caps protect the stoppers once the seals are off.
Planning a study with Prostamax 20mg
Start from the protocol. Total the amount every arm needs from the first time point to the last, divide by the 20mg in a vial and add a spare. It’s cheaper to order once than to wait on a second shipment halfway through.
Only reconstitute what you’ll use in the next few weeks. Sealed vials stay stable in the freezer, while a mixed vial should be finished within about 28 days.
Keep vials from one batch together in a study where you can. The batch number on the label ties each result back to its certificate of analysis.
