Prostamax Reconstitution Calculator

The calculator assumes that the peptide will have systemic effects and simply adds a fixed mass to the total body pool. However, Prostamax is described as a prostatotropic bioregulator, indicating a specific predilection for prostate tissue in experimental models. The KEDP tetrapeptide does not simply float around the body; it is designed to exert targeted effects on prostate cell signaling and chromatin structure in that specific organ. Therefore, the same mg dose calculated by your tool could produce a very different biological outcome in a prostate-focused study compared to a study on general immune function, a nuance the calculator cannot capture.

The small size and the presence of a proline residue provide conformational rigidity, which generally enhances stability. However, the standard reconstitution protocol for Prostamax is to add 2.5 mL of BAC water to a 20 mg vial, which yields a concentration of 8 mg/mL. Using this concentration, a standard research dose of, say, 2 mg would require 0.25 mL (25 units). The calculator's default "Best" match might suggest an even smaller volume (e.g., 1 mL) for mathematical neatness, but this would produce a highly concentrated solution (20 mg/mL) which, while possible, may not be optimal for solubility and injection comfort for this specific molecule. The empirical protocol uses a more dilute solution for practical handling.

Research protocols show a wide dosing range. A 20 mg vial can be reconstituted with 2.5 mL of BAC water, resulting in a concentration of 8 mg/mL. For a low dose of 0.5 mg, the injection volume would be 0.0625 mL (approx. 6.25 units). For a higher dose of 3 mg, the volume would be 0.375 mL (approx. 37.5 units). The calculator will show these volumes, but it cannot warn you that for very low doses (e.g., below 0.5 mg), the resulting volume on a standard 1 mL syringe may be so small that it leads to significant dosing errors. The calculator's "Doses per vial" display should be used with the understanding that the effective dose is determined by tissue-specific response, not a linear scale.

The calculator's colour coding is based purely on mathematical neatness for the specific mg dose you entered. The standard Prostamax protocol uses 3.0 mL of BAC water to create a concentration of 6.67 mg/mL. At this concentration, a U-100 insulin syringe has a simple relationship: 1 unit = 0.01 mL ≈ 66.7 mcg. This makes it easy to dial up a dose: a 500 mcg dose is 7.5 units, a 1 mg dose is 15 units, and a 2 mg dose is 30 units. The calculator may rate a 1 mL reconstitution as "Best" for some doses, but 1 mL creates a much higher concentration and smaller draw volumes. The 3.0 mL protocol is designed for practical, clear syringe conversions across a wide titration range, and you should prioritise this empirically validated volume over the calculator's aesthetic ranking.

The calculator's "Doses per vial" is a pure mathematical count based on mass. The lyophilised powder can be stored for up to 24 months at -20°C without significant degradation. However, once reconstituted with bacteriostatic water, the solution should be stored at 2–8°C and used within a 28-day window for optimal sterility and potency. If the calculator shows 40 "doses per vial" for a low-dose protocol, you will never be able to use all 40 doses from a single vial because the solution will exceed its safe 28-day usage period. You must align your protocol so that the total volume you reconstitute is fully used within 28 days, regardless of the theoretical "doses per vial" number.
