KPV (lysine-proline-valine) in brief
KPV (lysine-proline-valine) comes in 2 strengths from 5mg to 10mg per vial, each a sealed box of ten, from $39.40 to $56.54 a box. Per mg the spread is wide: KPV10 (10mg x 10 vials) works out at $0.565 per mg against $0.788 per mg for KPV5 (5mg x 10 vials), 28 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.
Nothing is on the shelf today: every strength is made to order, about four weeks, in any quantity.
What KPV (lysine-proline-valine) is
KPV is the tripeptide lysyl-prolyl-valine, the last three residues of alpha-melanocyte-stimulating hormone, positions 11 to 13 of its 13-residue chain. In the hormone the valine ends as an amide; KPV as supplied is the free acid. Formula C16H30N4O4, average mass 342.4, supplied as the acetate. With three residues and nothing to oxidise or deamidate it is chemically about as simple as a peptide gets; the only synthesis impurity of note is the dipeptide missing a residue.
It is small and hydrophilic. It dissolves instantly and keeps well dry.
Registry and identity
- Registries know KPV by its chemistry: GSRS as L-lysyl-L-prolyl-L-valine (UNII 7V6LGD8S5R, CAS 67727-97-3), also called ACTH-(11-13) there, and PubChem as CID 125672 under the title Msh (11-13). FDA GSRS, PubChem
- A 1:1 acetate, Lys-Pro-Val acetate, has its own record (UNII HX2YJ5Z225, CAS 2828433-34-5), 402.5 in all, so acetic acid is 14.9 percent of that salt (worked from its formula). FDA GSRS
- UniProt's pro-opiomelanocortin entry (P01189) places Lys-Pro-Val at 148 to 150, the end of alpha-MSH (138 to 150), where valine 150 is an amide; the KPV in GSRS, like this line (C16H30N4O4), ends in a free acid instead, so its [M+H]+ is at m/z 343.234 rather than the 342.250 of the amide (worked from C16H30N4O4 and C16H31N5O3 with NIST isotope masses). UniProt, FDA GSRS, NIST
- None of its three side chains is aromatic, so the tripeptide absorbs light through its peptide bonds, at 210 to 220 nm, and barely at 254 or 280 nm. FDA GSRS
A listing in these registers identifies a substance; it is not an approval of this line.
KPV beside BPC-157 and GHK-Cu
KPV works out at $0.565 per mg at 10mg (KPV10), its lowest by the single box. Its neighbours, on price alone: BPC-157 at $0.553 per mg at 10mg (BC10), 1,419.6 g/mol, set side by side in BPC-157 vs KPV; GHK-Cu at $0.052 per mg at 100mg (CU100), 401.9 g/mol.
Reading a KPV (lysine-proline-valine) certificate of analysis (COA)
- Oxidation: no methionine, tryptophan or cysteine in the chain, so oxidised forms are not the impurity to expect.
- Deamidation: no asparagine or glutamine, so the +1 mass deamidation impurity common in longer peptides does not apply.
- Charge: near neutral pH about +1, basic.
Worked out from what the sheet holds for this line; the batch certificate is the record. How to read one, and verify a batch number.

Questions about KPV (lysine-proline-valine)
What are KPV’s sequence, formula, molecular weight and CAS number?
Lys-Pro-Val, the last three residues of alpha-MSH, ending in a free acid where the hormone’s valine is an amide: C16H30N4O4, molecular weight (average mass) 342.4, CAS 67727-97-3, under which FDA’s GSRS files L-lysyl-L-prolyl-L-valine (UNII 7V6LGD8S5R). Its 1:1 acetate is filed apart, under 2828433-34-5.
Which longer chain on this list ends in KPV’s Lys-Pro-Val?
MT-1. Its thirteen residues follow alpha-MSH, save norleucine in fourth place and D-phenylalanine in seventh, and after glycine 10 its last three residues are KPV’s own. They close MT-1’s chain as the amide, Lys-Pro-Val-NH2, as they close the hormone’s, where this line ends in the free acid. Neither substitution falls inside them. No other sequence printed on this list holds the run: MT-2 and PT-141, the cyclic analogues, end on a lysine and carry no proline or valine.
How much does KPV (lysine-proline-valine) cost?
From $39.40 a sealed box of 10 vials, up to $56.54 for the largest strength sold singly, which works out at $0.565 per mg at its best-priced size. To a US address, freight is included from $1,000 of goods; below that it is the carrier’s rate for the carton or a flat $35.00, and to another country the desk quotes it; either way the figure is on the proforma before you pay. Every strength and its price per vial is in this page’s price table.
Which KPV (lysine-proline-valine) size is cheapest per mg?
KPV10, 10mg x 10 vials, at $0.565 per mg, which is 28 percent less per mg than KPV5, at $0.788 per mg. Larger vials cost less per mg across this range, so match the vial to the size of the work first, then compare per mg.
Can I buy a single vial of KPV (lysine-proline-valine)?
No. One sealed box of ten vials is the smallest quantity of a regular line; for KPV (lysine-proline-valine) that is KPV5, 5mg x 10 vials, at $39.40. A first order must reach $100 of goods, so KPV5 alone takes three boxes ($118.20) or one box beside other lines. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Which KPV (lysine-proline-valine) strengths are in stock today?
None today. Every strength is made to order, about four weeks, and can be ordered in any quantity.
How is KPV (lysine-proline-valine) stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of KPV (lysine-proline-valine)?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. KPV (lysine-proline-valine) is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.
Is a certificate of analysis (COA) provided for KPV (lysine-proline-valine)?
Yes. For KPV (lysine-proline-valine) the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
