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. 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.
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
Per-Peptide Breakdown by Dose
| Dose | Units | GHK-Cu | KPV | BPC-157 | TB-500 |
|---|---|---|---|---|---|
| 2mg | 5 units | 1.25mg | 250mcg | 250mcg | 250mcg |
| 4mg | 10 units | 2.50mg | 500mcg | 500mcg | 500mcg |
| 6mg | 15 units | 3.75mg | 750mcg | 750mcg | 750mcg |
The standard 10-unit dose (4mg total) delivers each peptide within its community-reported standalone dosing range:
| Peptide | Community-reported solo dose | Klow @ 10 Units |
|---|---|---|
| GHK-Cu | 1-2mg/injection | 2.50mg |
| KPV | 200-500mcg/injection | 500mcg |
| BPC-157 | 250-500mcg/injection | 500mcg |
| TB-500 | 250-750mcg/injection | 500mcg |
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
