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.
If you've mixed individual peptides or the Wolverine Stack before, this will feel familiar. If it's your first time, follow every step precisely. Most errors happen during mixing, not injection.
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.
Do not squirt water directly onto the powder. All four peptides in the Klow blend are fragile chains. Aggressive force can shear molecular bonds and reduce potency. Let gravity do the work.
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).
Never shake the vial. Shaking creates foam at the air-liquid interface, which can denature peptide molecules. If you see foam, you've been too aggressive.
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
Write the date and concentration (40mg/mL) on the vial. Refrigerate immediately at 36-46F (2-8C). The 28-day clock starts now.
Dilution Chart
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.
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

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 10 units/injection, 3x/week (maintenance):
- 30 units per week
- One vial lasts ~6.5 weeks

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. Always aim at the glass wall and let 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. Pull the vial out, draw your dose, put it back. Don't leave it on the counter while you 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.
Frequently Asked Questions
How much bacteriostatic water do I add to an 80mg Klow blend vial?
Adding 2mL of bacteriostatic water to the 80mg vial gives 40mg/mL concentration. For a standard 4mg dose (10 units), each injection delivers 2.5mg GHK-Cu, 500mcg KPV, 500mcg BPC-157, and 500mcg TB-500.
Is reconstituting a 4-peptide blend different from a single peptide?
The process is identical — add BAC water slowly along the glass wall, swirl gently, never shake. The only difference is each dose delivers four peptides in fixed ratio. You don't need separate vials or syringes.
How long does reconstituted Klow blend last?
Stored at 2-8C (refrigerator) with bacteriostatic water, reconstituted Klow is stable for up to 28 days. Never freeze reconstituted peptides and keep the vial upright.
Can I use a different BAC water volume for Klow?
Yes — 1mL gives higher concentration (80mg/mL, 5 units per 4mg) and 3mL gives lower (26.7mg/mL, 15 units per 4mg). 2mL is the sweet spot for clean syringe math.
What if the powder doesn't dissolve?
Let it sit refrigerated for 15-20 minutes and swirl again. Properly manufactured Klow dissolves within a few minutes. If particles remain after 30 minutes, the peptide may be degraded — contact your vendor.
