KPV
research guide

KPV is a tripeptide corresponding to the C-terminal sequence of alpha-melanocyte stimulating hormone (alpha-MSH). It has been studied mainly in animal models of colitis and inflammatory skin conditions for anti-inflammatory and antimicrobial activity linked to the melanocortin system. Human clinical trial data specific to KPV itself was not identified in the sources reviewed, and available evidence remains largely preclinical and mechanistic in scope.

01 · Start with identity

What is KPV?

KPV is a small peptide fragment studied in laboratory and animal research settings; it is not an FDA approved drug. It should not be confused with full-length alpha-MSH analogs such as afamelanotide, which have separate approval and safety data.

Also searched as: Lysine-proline-valine tripeptide, alpha-MSH C-terminal fragment

02 · Read the evidence

What the studies reported

01

Melanocortin system and inflammatory bowel disease

A review of the melanocortin system in inflammatory bowel disease discusses KPV alongside alpha-MSH as agents studied for anti-inflammatory signaling relevant to colitis models, describing mechanistic and preclinical evidence rather than completed patient trials [1].

02

Alpha-MSH related anti-inflammatory and antifibrotic actions

A review of alpha-melanocyte stimulating hormone actions describes antifibrotic and anti-inflammatory roles attributed to the melanocortin peptide family, providing mechanistic context for KPV as a related fragment rather than direct KPV trial data [2].

03

Tripeptide wound healing review context

A comprehensive review of tripeptides in wound healing and skin regeneration references KPV among short peptides studied for topical and inflammatory applications, again based on preclinical literature [3].

03 · Numbers in context

What does dosing evidence actually support?

Reviewed sources describe KPV activity mainly through animal colitis models and cell-based inflammatory assays, with doses reported by researchers on a per-kilogram basis for the specific animal studied in each experiment. No validated human dosing protocol for KPV, by any route of administration, was identified in the sources reviewed, so no regimen can be drawn from this research.

A study dose is not a personal dose. Population, route, formulation and supervision are part of the result. Online community schedules are not treated here as established clinical protocols.

04 · Safety and limits

What not to overlook

  • No completed human clinical trial specific to KPV was identified in the sources reviewed
  • Not an FDA approved drug and distinct from approved melanocortin agonists
  • Animal colitis model data does not establish a human dose or indication
  • Topical, oral and injectable products may behave differently and none were directly compared in the sources reviewed

05 · Product distinctions

Names are not interchangeable

Reign Peptide lists KPV as a lyophilized powder (10mg/vial, greater than or equal to 98% purity by third-party HPLC per the listing) and as a nasal spray solution, both described by the supplier as for in-vitro research use only. These are supplier research products, not a pharmaceutical formulation studied in the cited literature.

06 · Handling and storage

Follow validated product instructions

A single water volume, refrigerator temperature or expiry window cannot be assumed for every compound and formulation. Use the exact manufacturer documentation and a validated laboratory procedure. If stability, solvent compatibility or microbiological quality is not documented, those properties remain unverified.

Refrigeration, clear appearance and bacteriostatic water do not make an unverified research product suitable for injection. This guide does not provide a mixing or administration procedure.

The existing concentration calculator checks arithmetic only. It cannot choose a safe dose or establish compatibility, sterility or shelf life.

Questions still worth asking

What remains unresolved?

  • Would KPV show anti-inflammatory activity in a controlled human trial for an inflammatory bowel or skin condition?
  • How does route of administration affect KPV's local versus systemic anti-inflammatory activity?
