Reduces NF-κB/MAPK activity and cytokine levels in inflammation models.
BPC-157 (10 mg)
Gastric-derived pentadecapeptide explored for angiogenesis, endothelial migration, and VEGFR2 activation.
Engages ERK/Akt-eNOS pathways; increases vascular tube formation.
TB-500 (10 mg)
Actin-binding peptide studied for cell migration, angiogenesis, and VEGF regulation.
Upregulates VEGF in fibroblast migration assays; actin-polymerization mechanism.

Long-Term Cycling: 8 Weeks On, 8 Weeks Off
This extended cycling protocol prevents receptor downregulation and maintains long-term effectiveness.
- • Active Phase: 8 weeks following the 5-on/2-off weekly schedule
- • Rest Phase: 8 weeks complete cessation to reset receptors
- • Reassessment: Evaluate progress before starting next cycle
Reconstitution Instructions
Clean & Prepare
Wash hands thoroughly. Clean the KLOW80 vial stopper with an alcohol swab and allow to air dry.
Add Bacteriostatic Water
Draw 4 mL bacteriostatic water. Insert needle at angle, directing stream against glass wall—not directly onto powder.
Dissolve Gently
Swirl the vial gently until all peptide powder fully dissolves. Do NOT shake—this can degrade peptides.
Label & Store
Label with date and concentration (20 mg/mL). Refrigerate at 2-8°C (35-46°F). Stable for 30 days.
Injection Technique
Subcutaneous Administration
- Site Selection: Abdomen (2 inches from navel), outer thighs, back of upper arms, or upper buttocks
- Site Rotation: Rotate injection sites to prevent lipohypertrophy and maintain absorption
- Angle: Insert needle at 45-90 degree angle into pinched skin fold
- Speed: Inject slowly and steadily
- Disposal: Use sharps container for proper needle disposal
Storage & Handling
| Lyophilized Powder | Freezer at -20°C (-4°F) or below |
| Reconstituted Solution | Refrigerate at 2-8°C (35-46°F) for up to 30 days |
| Never Freeze | Once reconstituted—freezing denatures peptides |
Potential Side Effects
Most Common (Mild)
- Injection site reactions: redness, swelling, mild irritation
- Temporary fatigue or headache
- Mild nausea (rare)
When to Consult Healthcare Provider
- Persistent injection site reactions lasting >48 hours
- Signs of allergic reaction (hives, difficulty breathing)
- Unusual symptoms or concerning changes
All KLOW80 batches are third-party tested. Request Certificate of Analysis (COA) for verification.
Frequently Asked Questions
Common questions about the KLOW80 peptide blend:
What is the KLOW80 blend used for?
This pre-mixed blend combines four peptides (GHK-Cu, KPV, BPC-157, TB-500) studied for tissue repair, inflammation modulation, and recovery support. It's designed for research purposes.
How does KLOW80 differ from the GLOW blend?
KLOW80 includes KPV (an anti-inflammatory peptide), while GLOW focuses on ECM remodeling and angiogenesis without the KPV component. KLOW80 is preferred for inflammation-related research.
Does KLOW80 come pre-mixed or do I need to mix it?
KLOW80 comes as a lyophilized (freeze-dried) powder in a single vial. You will need to reconstitute it with bacteriostatic water before use. We provide the BAC water with your order.
How much bacteriostatic water do I add?
Add 4 mL of bacteriostatic water to the KLOW80 vial. This creates the correct concentration for the 15 units (0.15 mL) per dose protocol described in this guide.
Can I use sterile water instead of bacteriostatic water?
Bacteriostatic water is strongly recommended because it contains a preservative that prevents bacterial growth during the 28-day storage period. Sterile water lacks this protection.
What size syringe do I need?
We recommend using a U-100 insulin syringe (1 mL) with 29-31 gauge needle. These are included with your order and provide accurate measurement for the 15-unit dose.
How often should I inject KLOW80?
The standard research protocol is once daily, 5 days on and 2 days off. This cycling approach is common in peptide research to allow for receptor sensitivity maintenance.
Where should I inject?
Subcutaneous injection into fatty tissue is standard—typically the abdomen (avoiding 2 inches around the navel), thigh, or back of the arm. Rotate injection sites daily.
How long does one vial last?
With the standard 15 units daily (5 days/week) protocol, one vial provides approximately 5-6 weeks of research use.
How should I store my reconstituted KLOW80?
Refrigerate at 36-46°F (2-8°C) after reconstitution. Never freeze. Use within 28 days of mixing. Keep away from light.
Can I combine KLOW80 with tirzepatide?
These are separate products with different mechanisms. Using both simultaneously should be carefully considered based on your research goals. They are typically administered at different times of day.
What results should I expect and when?
As a research product, effects vary based on the study parameters. In research contexts, observations are typically noted over several weeks of consistent application.
