KPV is a synthetic tripeptide fragment derived from the C-terminal sequence of alpha-melanocyte-stimulating hormone (ฮฑ-MSH). It is extensively studied for its potent anti-inflammatory and immunomodulatory effects without the pigment-inducing properties of full-length ฮฑ-MSH. KPV has shown promise in gastrointestinal, dermatological, and autoimmune disease models, offering researchers a unique tool for exploring cytokine regulation, epithelial repair, and mucosal immune response.

KPV is a synthetic tripeptide fragment (Lys-Pro-Val) derived from the larger ฮฑ-MSH (alpha-melanocyte-stimulating hormone) peptide. It is widely researched for its potent anti-inflammatory and immunomodulatory effects, particularly in skin, gut, and autoimmune-related models.
KPV is believed to exert its effects by downregulating pro-inflammatory cytokines such as TNF-ฮฑ, IL-6, and IFN-ฮณ. It also inhibits NF-ฮบB activation, which plays a key role in chronic inflammation. Researchers study it for its ability to support immune balance and reduce tissue inflammation in preclinical models.
Our KPV is supplied as a sterile, lyophilized powder in single-use vials. Synthesized and tested in the USA, each batch is prepared under strict lab protocols to ensure high purity, safety, and consistency.

KPV (10 mg Vial) Dosage Protocol
Quickstart Highlights
KPV (LysineโProlineโValine) is a Cโterminal tripeptide fragment of ฮฑโmelanocyteโstimulating hormone (ฮฑโMSH) studied for its potent antiโinflammatory properties without melanotropic side effects[1][2]. Research demonstrates KPV reduces proโinflammatory cytokines in models of inflammatory bowel disease and systemic inflammation[3]. This educational protocol presents a onceโdaily subcutaneous approach using a practical dilution for precise insulinโsyringe measurements.
- Reconstitute: Add 3.0 mL bacteriostatic water โ ~3.33 mg/mL concentration.
- Typical daily range: 200โ500 mcg once daily (gradual titration recommended).
- Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL โ 33.33 mcg on a Uโ100 insulin syringe.
- Storage: Lyophilized: freeze at โ20 ยฐC (โ4 ยฐF) or below; after reconstitution, refrigerate at 2โ8 ยฐC (35.6โ46.4 ยฐF) and use within 30 days; avoid freezeโthaw cycles.
Dosing & Reconstitution Guide
Educational guide for reconstitution and daily dosing
Standard / Gradual Approach (3 mL = ~3.33 mg/mL)
| Week | Daily Dose (mcg) | Units (per injection) (mL) |
|---|---|---|
| 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 4โ8 | 500 mcg | 15 units (0.15 mL) |
Frequency: Inject once daily subcutaneously. This schedule uses the largest practical dilution (3.0 mL) to maintain manageable injection volumes. For โค10โunit (โค0.10 mL) administrations, consider 30โ or 50โunit insulin syringes for improved readability and more precise measurement[10].
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl/roll until dissolved (do not shake).
- Label and refrigerate at 2โ8 ยฐC (35.6โ46.4 ยฐF), protected from light.

Protocol Overview
Concise summary of the onceโdaily regimen.
- Goal: Support reduction of systemic inflammation and modulate immune responses without melanotropic effects[1][3].
- Schedule: Daily subcutaneous injections for 8โ12 weeks (extend to 16 weeks if desired).
- Dose Range: 200โ500 mcg daily with gradual weekly titration.
- Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for accurate unit measurements.
- Storage: Lyophilized frozen at โ20 ยฐC (โ4 ยฐF) or below; reconstituted refrigerated at 2โ8 ยฐC (35.6โ46.4 ยฐF); avoid repeated freezeโthaw.
Dosing Protocol
Suggested daily titration approach.
- Start: 200 mcg daily; increase by ~100 mcg weekly as tolerated[4][5].
- Target: 400โ500 mcg daily by Weeks 4โ8 for maintenance antiโinflammatory effects.
- Frequency: Once per day (subcutaneous).
- Cycle Length: 8โ12 weeks; optional extension to 16 weeks under monitoring.
- Timing: Any consistent time; rotate injection sites systematically.
Storage Instructions
Proper storage preserves peptide quality and stability.
- Lyophilized: Store at โ20 ยฐC (โ4 ยฐF) or below in dry, dark conditions; protect from moisture and light[6][7].
- Reconstituted: Refrigerate at 2โ8 ยฐC (35.6โ46.4 ยฐF); use within approximately 30 days[7].
- Allow vials to reach room temperature before opening to minimize condensation uptake.
- Avoid freezeโthaw cycles: Do not refreeze reconstituted peptide solutions; prepare aliquots if longโterm storage is needed[6].
Important Notes
Practical considerations for consistency and safety.
- Use new sterile insulin syringes for each administration; dispose in a sharps container immediately after use.
- Rotate injection sites systematically (abdomen, thighs, upper arms) at least 1โ2 inches apart to reduce local irritation and prevent lipohypertrophy[8].
- Inject slowly; wait a few seconds before withdrawing the needle to prevent solution backflow.
- Document daily dose, injection site, and any observations to maintain consistency and track tolerability.
- If injectionโsite reactions (redness, mild swelling) occur, apply a cool compress and monitor; persistent reactions warrant protocol review.
How This Works
KPV is the Cโterminal tripeptide sequence (residues 11โ13) of ฮฑโmelanocyteโstimulating hormone (ฮฑโMSH), retaining potent antiโinflammatory activity without the hormone's melanotropic effects[1][2]. Preclinical studies demonstrate KPV reduces proโinflammatory cytokines (TNFโฮฑ, ILโ6, ILโ1ฮฒ) and modulates immune cell activity in models of inflammatory bowel disease, colitis, and systemic inflammation[3]. The peptide's mechanism involves inhibition of nuclear factor kappa B (NFโฮบB) signaling and modulation of inflammatory mediator release[2]. Subcutaneous administration provides systemic delivery with rapid absorption and sustained antiโinflammatory effects observed in daily dosing protocols[4].
Potential Benefits & Side Effects
Observations from preclinical and earlyโstage research.
- Antiโinflammatory activity: Reduces proโinflammatory cytokines and modulates immune responses in models of inflammatory bowel disease and systemic inflammation[3].
- Oral and subcutaneous efficacy: Multiple routes of administration show activity, with subcutaneous injection favored for systemic delivery and consistent bioavailability[4].
- Wound healing support: Preclinical data suggest KPV may support tissue repair and wound healing processes through inflammatory modulation[5].
- Generally well tolerated: Occasional mild injectionโsite reactions (redness, slight swelling) may occur; systemic side effects are rarely reported in research protocols.
- No melanotropic effects: Unlike full ฮฑโMSH, KPV does not affect melanocyte activity or skin pigmentation[1].
Lifestyle Factors
Complementary strategies for optimizing inflammatory balance.
- Antiโinflammatory diet: Emphasize whole foods, omegaโ3 fatty acids, polyphenols, and minimize processed foods and refined sugars.
- Stress management: Chronic stress elevates inflammatory markers; incorporate stressโreduction practices (meditation, yoga, adequate sleep).
- Physical activity: Regular moderate exercise supports healthy inflammatory balance; avoid overtraining which can increase inflammation.
- Sleep optimization: Prioritize 7โ9 hours of quality sleep nightly to support immune regulation and inflammatory homeostasis.
- Gut health: Support microbiome diversity through probioticโrich foods and adequate fiber intake, particularly relevant for inflammatory bowel conditions.
Injection Technique
General subcutaneous guidance from clinical bestโpractice resources[8][9].
- Clean the vial stopper and injection site with alcohol swabs; allow to dry completely (10โ15 seconds).
- Pinch a 1โ2 inch skinfold; insert the needle at 45โ90ยฐ angle into subcutaneous tissue[8].
- Do not aspirate for subcutaneous injections; inject slowly and steadily over 3โ5 seconds.
- Withdraw the needle smoothly and apply gentle pressure with a clean alcohol swab (do not rub the site).
- Rotate sites systematically using a pattern (e.g., alternating between right/left abdomen, right/left thigh) to avoid lipohypertrophy and maintain consistent absorption[9].
- Preferred sites: abdomen (at least 2 inches from navel), anterior/lateral thigh, or outer upper arm (if administering to self, abdomen and thigh are easiest).
