KPV reconstitution and storage
KPV's numbers in one place: three amino acids at 353 g/mol, the vial size, concentration table and what its report should show.
Published September 4, 2026
KPV is three amino acids: lysine, proline, valine. At 353 g/mol it is the smallest thing we sell, and the molar numbers reflect that.

Identity
| Sequence | KPV |
| Formula | C16H27N5O4 |
| Molecular weight | 353.42 g/mol |
| CAS | 67727-97-3 |
| Vial size we sell | 10 mg |
It is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone, which puts it in the same family as the melanocortin peptides, though it is studied in a different context.

KPV vial sizes we sell, at four diluent volumes. Molarity uses 353.42 g/mol. Other volumes
A 10 mg vial is about 28.3 micromoles. That is the second highest molar content in the catalog after GHK-Cu, and it is entirely because the molecule is tiny. The KPV calculator has the weight preset.
Handling
Water down the inside wall, swirl, do not shake. Small peptides dissolve fast. Freezer for the dry powder long term, fridge short term and once reconstituted. Storage guide.
On the report
Observed mass near 353.42, HPLC purity at 99% or higher, matching batch number, named lab. At this size a mass-spec result is very precise, so the identity check is unambiguous. Look up a batch.
In the blends
KPV appears in the KPV + GHK-Cu blend and in KLOW, which adds it to BPC-157, TB-500 and GHK-Cu. A blend's mass is the combined content across components. Peptide blends vs single vials covers when to buy which.
Every KPV vial from pepuro ships free, from Calgary, the same business day your e-Transfer clears, with a QR code on the vial that opens its Janoshik Analytical report.

Frequently asked questions
What is the molecular weight of KPV?+
353.42 g/mol, formula C16H27N5O4. It is the smallest peptide in the catalog.
What is KPV made of?+
Three amino acids: lysine, proline and valine. It is the C-terminal tripeptide of alpha-MSH.
How much water do I add to a 10 mg KPV vial?+
1 mL gives 10 mg/mL, 2 mL gives 5 mg/mL, 5 mL gives 2 mg/mL. At 353.42 g/mol, 10 mg is about 28 micromoles.
Which blends contain KPV?+
The KLOW blend and the KPV + GHK-Cu blend. Each vial's report states the ratio for that batch.
