KPV reconstitution table
What different amounts of water give you, for each quick-pick vial size. This is arithmetic, not a recommendation: the right amount of water is whatever makes your measurements easy and matches any instructions you were given.
| Vial | Water | Concentration | Per unit (0.01 mL) | Per 10 units (0.1 mL) |
|---|---|---|---|---|
| 5 mg | 1 mL | 5 mg/mL | 50 mcg | 500 mcg |
| 5 mg | 2 mL | 2.5 mg/mL | 25 mcg | 250 mcg |
| 5 mg | 3 mL | 1.67 mg/mL | 16.67 mcg | 167 mcg |
| 10 mg | 1 mL | 10 mg/mL | 100 mcg | 1 mg |
| 10 mg | 2 mL | 5 mg/mL | 50 mcg | 500 mcg |
| 10 mg | 3 mL | 3.33 mg/mL | 33.33 mcg | 333 mcg |
How the math works for KPV
A 10 mg KPV vial holds 10,000 mcg. Mixed with 2 mL of water, that's 10,000 ÷ 2 = 5,000 mcg per mL. One unit on a U-100 syringe is 0.01 mL, so each unit holds 50 mcg. More water spreads the same 10 mg across more units; less water packs it into fewer.
mcg per unit = concentration ÷ 100
Units to draw = amount (mcg) ÷ mcg per unit
What is KPV?
KPV is a three-amino-acid peptide (lysine, proline, valine) that forms the tail end of alpha-MSH, a natural hormone. Researchers attribute much of alpha-MSH's anti-inflammatory activity to this fragment, based on cell and animal studies; there are no human trials of KPV itself in that review.
Frequently asked questions
How much water do I add to a 10 mg KPV vial?
There's no single right amount. Less water makes each unit stronger and harder to measure; more water makes each unit weaker and easier to measure. For a 10 mg vial, 1 mL gives 100 mcg per unit, 2 mL gives 50 mcg, and 3 mL gives 33.33 mcg. If your KPV was prescribed, use the amount in your prescription instructions.
How many mcg of KPV are in one unit?
It depends on the vial size and how much water you add: mcg per unit = (mg in the vial × 1,000) ÷ (mL of water × 100). With a 10 mg vial and 2 mL of water, that's 50 mcg per unit on a U-100 syringe.
Is KPV FDA approved?
No. KPV isn't an FDA-approved drug. Removed from Category 2 in April 2026. Recommended for the 503A bulks list on July 23, 2026, against FDA staff's recommendation.
