SLU-PP-332 reconstitution calculator.
Pre-filled with the 50 mg vial and 2 mL of bacteriostatic water the REGEN catalog reports for SLU-PP-332. Every field is editable.
The numbers for a 50 mg SLU-PP-332 vial
Reconstituting a 50 mg vial with 2 mL of bacteriostatic water gives a concentration of 25 mg/mL. On a U-100 insulin syringe, where one unit is 0.01 mL, that puts 250 mcg in every unit drawn.
A 25000 mcg dose at that concentration is 1 mL, which is 100 units on the syringe, and the vial holds about 2 of them.
Those are the values the calculator above opens with. The vial size and water volume are the amounts the REGEN catalog reports for SLU-PP-332; change any field and the arithmetic follows.
What the research reports for SLU-PP-332
Published protocols for SLU-PP-332 report 25–50 mg, 1x daily. That is what the literature describes, not a recommendation. The calculator starts at the low end of it. The SLU-PP-332 reference page carries the evidence grade, the side-effect profile, and the primary sources behind that range.
SLU-PP-332 reconstitution chart for a 50 mg vial
The same 50 mg of SLU-PP-332 at four common water volumes. More water does not mean more compound, it spreads the same amount across a bigger volume, so the same dose is drawn to a higher number of units. That is usually the safer direction to be imprecise in: small errors on a longer draw matter proportionally less.
| Bacteriostatic water | Concentration | Per unit (U-100) | Units for 25000 mcg |
|---|---|---|---|
| 1 mL | 50 mg/mL | 500 mcg | 50 units |
| 2 mL (catalog) | 25 mg/mL | 250 mcg | 100 units |
| 3 mL | 16.67 mg/mL | 166.7 mcg | 150 units |
| 5 mL | 10 mg/mL | 100 mcg | 250 units |
"Units" here means syringe graduations, not international units. They are unrelated measures that share a name, and conflating them is its own category of mistake. The reconstitution calculator explains the arithmetic behind these columns in full.
