Reconstitution

Add 3.0 mL BAC water → 3.33 mg/mL

Daily dose range

300–500 mcg (titrated)

Unit math (U-100 syringe)

1 unit = 0.01 mL ≈ 33.3 mcg

Storage (lyophilized)

Freeze at −4 °F · Reconstituted: 36–46 °F · Use within 28 days

Dosing & Reconstitution Guide

The protocol below uses a 3.0 mL reconstitution volume to keep injection units comfortably above 10 on a standard U-100 insulin syringe, reducing measurement error. Doses are titrated as shown below.

Phase	Daily dose	U-100 units	Injection volume
Standard	300–500 mcg	9–15 units	0.09–0.15 mL

Route: Subcutaneous / Oral · Frequency: Once daily · Cycle: 4–8 weeks

Reconstitution steps

Draw 3.0 mL of bacteriostatic water into a sterile syringe.

Inject the water slowly down the interior wall of the peptide vial -never directly onto the powder -to prevent foaming and denaturation.

Swirl or roll gently until fully dissolved. Do not shake. The lyophilized powder should dissolve completely within 30–60 seconds.

Label the vial with the reconstitution date and concentration (3.33 mg/mL). Refrigerate at 36–46 °F, protected from light. Use within 28 days.

Research use only. This protocol is derived from published preclinical and early-phase clinical literature. KPV is not FDA-approved for human use. This information is not medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before beginning any peptide protocol.

Storage Instructions

Lyophilized (dry powder)

−4 °F

Store frozen in dry, dark conditions. Minimize humidity exposure. Stable for 12–24 months when properly stored.

Reconstituted (in solution)

36–46 °F

Refrigerate after reconstitution. Use within 28 days. Do not refreeze reconstituted solution -freeze-thaw cycles degrade peptide integrity.

Allow refrigerated vials to reach room temperature before opening to minimize condensation uptake. Always inspect for cloudiness or particulates before use -discard if present.

How KPV Works

KPV (Lys-Pro-Val) is the C-terminal tripeptide fragment of alpha-melanocyte stimulating hormone (α-MSH). Unlike full-length α-MSH, KPV retains potent anti-inflammatory activity while being resistant to protease degradation due to its minimal size. It acts primarily through MC1R (melanocortin 1 receptor) in peripheral tissues, suppressing NF-κB-mediated inflammatory signaling and reducing TNF-α, IL-6, and IL-1β production.^[1]

A distinctive feature of KPV is its oral bioavailability for gastrointestinal applications, making it unique among anti-inflammatory peptides. Animal models of inflammatory bowel disease (IBD) have demonstrated significant efficacy with both oral and subcutaneous KPV administration, reducing colonic inflammation and improving tissue histology scores.^[2]

Observed Effects & Side Effect Profile

The following observations are derived from preclinical literature and limited early-phase human data. They do not constitute clinical claims.

Reported benefits (research literature)

Potent NF-κB inhibition -suppresses TNF-α, IL-6, and IL-1β
Protease-resistant due to minimal tripeptide size
Orally bioavailable for GI applications -unique among anti-inflammatory peptides
Significant IBD efficacy in animal models via both oral and SC routes

Known limitations & side effects

Human clinical trial data not yet available for IBD applications
Optimal dosing for various inflammatory conditions not established
MC1R agonism could theoretically affect melanogenesis at sustained doses
Not FDA-approved for any indication

Lifestyle Considerations

While the following suggestions are not protocol requirements, research on tissue repair and peptide efficacy consistently highlights these as factors that influence outcomes:

Protein intake. Collagen synthesis and tissue remodeling require adequate dietary protein. Research generally supports 1.6–2.2 g/kg/day during active recovery periods.

Sleep. The majority of tissue repair and growth hormone secretion occurs during deep sleep stages. 7–9 hours of quality sleep per night supports the biological environment in which recovery peptides operate.

Activity balance. Avoid complete immobilization (which impedes collagen remodeling) and overuse (which re-injures tissue). Progressive loading appropriate to the injury stage supports functional recovery.

Stress management. Elevated cortisol chronically impairs immune function and tissue repair. Evidence-based stress reduction techniques support the recovery environment.

Injection Technique

Standard subcutaneous injection guidance from clinical best-practice references.

Wash hands thoroughly. Clean your work surface. Gather all supplies before beginning.

Wipe the vial rubber stopper with a fresh alcohol swab. Allow it to dry completely before inserting a needle.

Draw the calculated dose volume into a sterile insulin syringe. Invert the syringe and tap to remove air bubbles; expel them before withdrawing the needle from the vial.

Select an injection site: abdomen (at least 2 inches from the navel), outer thigh, or upper outer arm. Clean with a fresh alcohol swab and allow to dry.

Pinch a fold of skin between thumb and forefinger. Insert the needle at a 45–90° angle depending on body fat thickness -45° for leaner individuals, 90° for more subcutaneous tissue.

Do not aspirate. Current clinical guidelines do not recommend aspiration for subcutaneous injections. Inject slowly and steadily over 2–3 seconds.

Wait 3–5 seconds after the plunger bottoms out before withdrawing the needle at the same angle. Apply gentle pressure with a clean swab -do not rub vigorously.

Rotate injection sites systematically with every dose. Reusing the same site repeatedly causes lipohypertrophy (hardened fat tissue) which reduces absorption consistency.

Dispose of used needles and syringes immediately in a puncture-resistant sharps container. Never recap needles by hand.

Important Notes

⚠

Research use only. KPV is not FDA-approved for human use. Human clinical data may be limited. Do not use without consulting a qualified healthcare professional.

◎

One syringe per injection. Never reuse needles or syringes. Each injection requires a fresh, sterile syringe to prevent contamination and infection risk.

◎

Document your protocol. Record daily dose, injection site, and any observations. This supports consistency and allows you to identify patterns or issues over the course of the cycle.

◎

Inspect before each use. The reconstituted solution should be clear and colorless. Discard if cloudy, discolored, or if particulates are visible.
