Prostamax Dosing Calculator
Prostamax (KEDP, Lys-Glu-Asp-Pro) is an unapproved Khavinson tetrapeptide studied in Russian preclinical models of prostate aging and BPH.
Pre-filled with the most-reported clinical reconstitution protocol for Prostamax. See how 1 mL and 2 mL of bacteriostatic water change concentration and syringe-draw volume, then adjust the calculator below for your own vial.
Quick answer · Clinical protocol
A 5 mg vial of Prostamax reconstituted with 2 mL of bacteriostatic water yields a concentration of 2.50 mg/mL. At that concentration, a 1 mg dose of Prostamax equals 40 units on a U-100 insulin syringe (0.400 mL). Prostamax is typically administered every other day.
Prostamax reconstitution: 1 mL vs 2 mL bac water
Bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 5 mg vial.
| BAC water added | Concentration | Volume per 1 mg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 5.00 mg/mL | 0.200 mL | 20 units |
| 2 mL | 2.50 mg/mL | 0.400 mL | 40 units |

Reported Khavinson bioregulation-clinic course (BPH context)
Clinical- Dose
- Low microgram per kilogram range (reported, not validated)
- Frequency
- Daily during course
- Duration
- 10-20 days, then extended off-period
Reported from Russian clinic practice; not PubMed-indexed; not validated by randomised trial. Route was historically oral (sublingual) in early Khavinson framework.
Prostamax reconstitution & storage
Prostamax is typically sold as a lyophilised powder. Reconstitution with bacteriostatic 0.9% sodium chloride is the standard handling for short peptides; however, no manufacturer with FDA-recognised cGMP status produces Prostamax, so reconstitution guidance comes only from research-chemical vendor literature.
Lyophilised powder: refrigerate (2-8 C) for long-term storage. Reconstituted solution: refrigerate and use within 14-28 days per general short-peptide guidance. No Prostamax-specific stability data are available in PubMed-indexed literature.
Prostamax dosing FAQ
How much bacteriostatic water should I add to a 5 mg vial of Prostamax?
The community standard is 2 mL of bacteriostatic water for a 5 mg Prostamax vial. That gives a concentration of 2.50 mg/mL, so a 1 mg dose is 40 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 5.00 mg/mL and halves the draw to 20 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 1 mg dose of Prostamax?
On a standard U-100 insulin syringe, a 1 mg dose of Prostamax is 40 units when the 5 mg vial is reconstituted with 2 mL of bacteriostatic water (2.50 mg/mL). If you use 1 mL of bac water instead, draw 20 units (5.00 mg/mL).
What is the standard Prostamax dose?
Clinical protocols for Prostamax typically use 1 mgâ2 mg every other day via subcutaneous injection. 1 mg is a common starting dose. Community-sourced from forums and vendor packaging; no PubMed-indexed pharmacokinetic basis. Subcutaneous bioavailability of KEDP in humans has not been characterised in indexed literature.
How long does a vial of Prostamax last at 1 mg every other day?
A 5 mg vial of Prostamax contains roughly 5 doses at 1 mg per injection. At every other day dosing, that is approximately 10 days (about 1 weeks) of supply per vial. Reconstituted Prostamax should generally be used within 28 days when refrigerated.
Where do you inject Prostamax?
Prostamax is typically injected subcutaneously. Common sites reported in the literature and by users include: Abdominal subcutaneous tissue (community-reported), Anterior thigh subcutaneous tissue (community-reported). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for Prostamax?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Prostamax because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
