KPV Dosage & Reconstitution Guide

Reconstitution

KPV ships as a freeze-dried (lyophilized) powder that has to be mixed with bacteriostatic water before use. Draw 1 mL of bacteriostatic water into a syringe and add it to a 5 mg vial, letting the stream run down the inside wall of the glass rather than blasting the powder directly. Swirl gently — never shake — until the solution is clear, then keep it refrigerated.

Worked example. 1 mL into a 5 mg vial gives a concentration of 5 mg/mL (5000 mcg/mL). A 250 mcg dose then works out to 0.05 mL = 5 units on a U-100 insulin syringe. Scale the water volume up or down to make your target dose land on an easy-to-read mark (1 unit = 0.01 mL).

1. Wipe both vial stoppers (peptide and bacteriostatic water) with an alcohol swab and let them dry.
2. Draw 1 mL of bacteriostatic water into a syringe.
3. Inject it slowly against the inside wall of the peptide vial.
4. Swirl gently until fully dissolved; do not shake.
5. Label the vial with the contents, concentration, and date, and store it in the refrigerator.

Dosing schedule

Timing & cycling

Subcutaneous dosing is for systemic anti-inflammatory effect and can be given at any consistent time of day. For gut-targeted use it is instead often taken orally (capsule or reconstituted liquid) with or before food so more of the peptide reaches the intestine.

Cycle length. Commonly run in 4-8 week blocks, then reassess; can repeat after a short break. No established long-term human data.

Storage & handling

Keep the lyophilized (unmixed) vial refrigerated at 2–8 °C (36–46 °F) in a dry, dark place — it tolerates short periods at room temperature during shipping. Once reconstituted, store it at 2–8 °C, never frozen, and use it within about 2–4 weeks (sooner if the solution turns cloudy or discolored). Swab the stopper before every draw and use a fresh needle each time.

Supplies you'll need

• KPV vials — about 6 for an 8-week run at the upper dose
• Bacteriostatic water — 1 mL per vial (a 10–30 mL multi-dose bottle covers several vials)
• U-100 insulin syringes (0.3–0.5 mL / 30–50 unit barrels are easiest to read) — roughly 56 for 8 weeks, plus spares
• Alcohol swabs — one per injection and one per vial draw
• Sharps container for safe needle disposal

Key points

• Unlike full alpha-MSH or melanotan peptides, KPV does not stimulate melanin and does not cause skin tanning.
• Used two ways: subcutaneously for a systemic, whole-body anti-inflammatory effect, and orally (capsules or reconstituted liquid) to target gut inflammation directly.
• Frequently stacked with BPC-157 in community gut-healing protocols.
• Evidence is almost entirely preclinical (cell and rodent colitis models); there are no large human trials, so it remains research-use-only.
• Reconstituted solution should be refrigerated and used within a few weeks; vendor purity varies, so third-party testing matters.

What to monitor

Track the specific inflammatory or GI symptoms being targeted (pain, stool frequency and consistency, skin), plus injection-site reactions and general tolerance.

Legal & prescription status

Research chemical / research-use-only. KPV is not FDA-approved and is not a licensed medicine; vendors sell it 'for laboratory research only.'
