KPV is a potent anti-inflammatory peptide, a fragment of α-MSH, that reduces inflammatory cytokines without affecting pigmentation. It's typically dosed subcutaneously daily, often in short cycles, with concentrations easily adjusted for precise measurements using insulin syringes.

Dosing schedule
| Phase | Dose | On a U-100 syringe |
|---|---|---|
| Week 1 | 200 mcg | 6 units (0.06 mL) |
| Week 2 | 300 mcg | 9 units (0.09 mL) |
| Week 3 | 400 mcg | 12 units (0.12 mL) |
| Weeks 4–8 | 500 mcg | 15 units (0.15 mL) |
Protocol detail
| Start | Begin with 200 mcg daily; increase the dose by approximately 100 mcg weekly as tolerated. |
|---|---|
| Target | Aim for a daily dose of 400–500 mcg by Weeks 4–8 to achieve maintenance anti-inflammatory effects. |
| Frequency | Inject once per day subcutaneously. |
| Cycle Length | An 8–12 week cycle is typical; extension to 16 weeks can be considered with observation. |
| Timing | Administer at a consistent time each day; consistently rotate injection sites. |

How it works
KPV is a short peptide sequence derived from α-melanocyte-stimulating hormone (α-MSH). It exhibits powerful anti-inflammatory effects by reducing key pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1β, without triggering the pigment-producing effects of the full α-MSH molecule. KPV primarily works by inhibiting the NF-κB signaling pathway, which is central to inflammatory responses. Subcutaneous injection ensures effective systemic delivery, allowing for rapid absorption and sustained therapeutic benefits in conditions marked by inflammation.
Reported effects
- Reduces pro-inflammatory cytokines and modulates immune responses.
- Effective via subcutaneous injection for systemic delivery.
- May support tissue repair and wound healing.
- Generally well tolerated with minimal side effects.
- Does not cause skin pigmentation changes.
Reported side effects
- Mild injection-site reactions (redness, slight swelling) may occur.
- Systemic side effects are rarely reported.
Storage
Lyophilised (unmixed)
Store at -20 °C (-4 °F) or below in dry, dark conditions; protect from moisture and light.
After reconstitution
Refrigerate at 2–8 °C (35.6–46.4 °F) and use within 30 days; avoid freeze–thaw cycles.
Supplies
| Peptide vials (KPV, 10 mg each) | Approximately 3 vials for 8 weeks, 4 vials for 12 weeks, or 6 vials for 16 weeks. |
|---|---|
| Insulin Syringes (U-100) | 7 syringes per week (56 for 8 weeks, 84 for 12 weeks, 112 for 16 weeks). |
| Bacteriostatic Water (10 mL bottles) | 1-2 bottles depending on cycle length (approx. 3.0 mL per vial for reconstitution). |
| Alcohol Swabs | 14 swabs per week (2 per day), requiring 2-3 boxes for an 8-16 week cycle. |
Important notes
- Always use a new sterile insulin syringe for each injection and dispose of it properly in a sharps container.
- Rotate injection sites regularly (abdomen, thighs, upper arms) to prevent local irritation and lipohypertrophy.
- Inject slowly and allow a few seconds before withdrawing the needle to prevent solution backflow.
- Document daily doses, injection sites, and any observations for consistency and to track tolerability.
- If persistent injection-site reactions occur, review the protocol.
Frequently asked questions
What is KPV typically used for?
KPV is primarily researched for its potent anti-inflammatory effects. It's often studied in contexts of systemic inflammation, inflammatory bowel disease, and immune modulation, without the melanotropic (skin-darkening) side effects of its parent hormone.
How should I store KPV before and after reconstitution?
Lyophilized (powder) KPV should be stored frozen at -20 °C (-4 °F) or colder, in a dark, dry place. Once reconstituted with bacteriostatic water, it needs to be refrigerated at 2–8 °C (35.6–46.4 °F) and is typically stable for about 30 days. Avoid freezing reconstituted solutions.
Why is it important to rotate injection sites?
Rotating injection sites (e.g., abdomen, thighs, upper arms) is crucial to prevent localized irritation, discomfort, and a condition known as lipohypertrophy, which can impair absorption. Consistent rotation helps ensure better absorption and reduces tissue damage.
Can KPV affect my skin pigmentation?
No, KPV is a specific fragment of α-melanocyte-stimulating hormone (α-MSH) that retains the anti-inflammatory properties but does not possess the melanotropic (skin-darkening) effects of the full hormone. Studies indicate it does not influence skin pigmentation.
