How to Mix Klow Blend: 80mg Reconstitution Guide

The Klow blend is an 80mg vial containing four peptides: GHK-Cu (50mg), KPV (10mg), BPC-157 (10mg), and TB-500 (10mg). Reconstitution follows the same process as any lyophilized peptide — add bacteriostatic water, swirl, refrigerate. The only difference is the syringe math: each dose delivers all four peptides in a fixed ratio.

Quick answer: documented protocols add 2 mL of bacteriostatic water to the 80 mg KLOW vial, producing 40 mg/mL. At that concentration a 10-unit draw on a U-100 insulin syringe corresponds to a 4 mg blend dose — 2.5 mg GHK-Cu, 500 mcg BPC-157, 500 mcg TB-500, and 500 mcg KPV. The interactive calculator and full dilution chart below cover any other BAC water volume or dose.

If you've mixed individual peptides or the Wolverine Stack before, this will feel familiar. For first-time preparation, standard sterile-handling technique requires each step in sequence. Most errors happen during mixing, not injection.

Research-context information only. The KLOW blend is a research-peptide blend (containing GHK-Cu, KPV, BPC-157, and TB-500). Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done.

What You Need

Gather everything before starting:

• Klow blend vial (80mg lyophilized powder — 50mg GHK-Cu + 10mg KPV + 10mg BPC-157 + 10mg TB-500)
• Bacteriostatic water (BAC water) — not sterile water, not saline
• 3mL syringe with 18-25ga needle — for drawing and transferring BAC water
• Insulin syringes — 1mL (100 unit), 29-31 gauge, for daily injections
• Alcohol swabs — clean vial tops before every puncture
• Sharps container — safe needle disposal
• Clean, flat workspace

Why BAC water, not sterile water? BAC water contains 0.9% benzyl alcohol that prevents bacterial growth. Sterile water has no preservative — the vial must be used within 24 hours. BAC water gives you up to 28 days refrigerated, which matters when one Klow vial provides 20+ injections.

Step-by-Step Reconstitution

Step 1: Clean Both Vial Tops

Wipe the rubber stoppers on both the Klow vial and BAC water vial with separate alcohol swabs. Let them air dry for 10 seconds. This prevents contamination.

Step 2: Draw 2mL Bacteriostatic Water

Using the 3mL syringe, draw exactly 2mL of BAC water. This is the recommended dilution for the 80mg Klow vial — it produces clean, round numbers for every common dose.

Step 3: Add Water to the Vial — Slowly

Insert the needle into the Klow vial at an angle. Aim the needle tip at the glass wall, not at the powder cake. Let the water trickle down the inside wall of the vial slowly.

Documented protocols direct the stream at the glass wall, not the powder — direct pressure can shear peptide bonds. All four peptides in the Klow blend are fragile chains, and aggressive force can reduce potency. Letting gravity do the work is the documented approach.

Step 4: Swirl Gently — Never Shake

Remove the syringe. Gently rotate the vial between your fingers with a slow swirling motion. The powder should dissolve within 2-5 minutes into a clear solution. The GHK-Cu component may give a very slight blue-green tint — this is normal (it's a copper complex).

Documented handling protocols avoid shaking; agitation creates foam at the air-liquid interface that can denature peptide molecules. Foam is a sign the vial has been handled too aggressively.

If particles remain after 5 minutes of gentle swirling, refrigerate for 15-20 minutes and try again. Properly manufactured Klow dissolves readily.

Step 5: Label and Refrigerate

Standard practice labels the vial with reconstitution date and concentration (40mg/mL) and refrigerates immediately at 36-46F (2-8C). The 28-day clock starts now.

KLOW 80mg Reconstitution and Dosage Chart

At the commonly documented 2 mL of BAC water, the 80 mg KLOW vial reconstitutes to 40 mg/mL. The chart below shows the syringe draw for the three common BAC water volumes; the 2 mL row gives the cleanest, round-number math.

Why 2mL? At 40mg/mL total concentration, 10 units on a U-100 insulin syringe delivers exactly 4mg of total blend — clean math with no fractions.

KLOW Dose Calculator

Enter any BAC water volume and blend dose to see the exact syringe draw and how many mcg of each of the four peptides it delivers:

Syringe Math for All 4 Peptides

Here's the formula:

Concentration = Total Peptide (mg) / Water Added (mL)

80mg / 2mL = 40mg/mL

Units to inject = Desired Dose (mg) / Concentration (mg/mL) x 100

4mg / 40mg/mL x 100 = 10 units

Per-Peptide Breakdown by Dose

At the 10-unit draw (4mg total), GHK-Cu (2.50mg) sits above the community-reported solo range, while KPV, BPC-157, and TB-500 sit at or within the upper end of theirs:

Ranges reflect community-reported single-peptide protocols; individual sources vary.

Vial Duration

At 10 units/injection, 5x/week (loading phase):

• 50 units per week
• 200 units per vial (2mL = 200 units on U-100 syringe)
• One vial lasts 4 weeks

At 5 units/injection, 3x/week (maintenance — half the loading dose):

• 15 units per week
• One vial lasts ~13 weeks

Storage Rules

Key rules:

• Refrigerate immediately after reconstitution. Every hour at room temperature reduces potency.
• Never freeze reconstituted solution. Ice crystals shear peptide bonds. Only freeze lyophilized (powder) vials.
• Store upright. Keeps the rubber stopper from prolonged contact with the solution.
• Keep away from light. Direct sunlight accelerates degradation. Back of the fridge is ideal.
• Fresh syringe every draw. Each needle puncture introduces contamination risk.

Pro tip: If you buy multiple vials for a 12-week cycle, keep extras in the freezer as powder. Only reconstitute when the current vial runs out.

Common Mistakes

Spraying BAC Water Directly onto the Powder

The most common error. High-pressure water hitting the lyophilized cake denatures peptide chains. Documented technique directs the stream at the glass wall, letting water roll down to the powder.

Shaking the Vial

Peptides are proteins. Shaking creates foam at the air-liquid interface, which denatures molecules at the boundary. If your solution is foamy, you've damaged some of the peptide. Always swirl gently.

Using Sterile Water Instead of BAC Water

Sterile water works for reconstitution but has no preservative. You'd need to use the entire vial within 24 hours — impossible with 20+ doses in a Klow vial. BAC water's benzyl alcohol keeps bacteria from growing for up to 28 days.

Storing at Room Temperature

Reconstituted peptides degrade rapidly above refrigerator temperature. Community resources describe pulling the vial out, drawing the dose, and returning it rather than leaving it on the counter during prep.

Forgetting to Label

With multiple peptide vials in the fridge, unlabeled vials lead to confusion. Write the peptide name, reconstitution date, and concentration directly on the vial.
