Blend
Type
KLOW is a four-peptide regenerative blend combining KPV (~342 Da), GHK-Cu (~340 Da), BPC-157 (~1419 Da), and TB-500 (~4963 Da) into a single lyophilized vial. Each component is individually supported by preclinical and limited clinical data, but the combination itself has not been studied in formal trials — the PRECLINICAL status applies to the blend as a unit. It targets overlapping biological pathways — angiogenesis, actin-mediated cell migration, NF-κB-driven inflammation, and copper-mediated collagen synthesis — to support comprehensive tissue repair in research and clinical wellness settings.

Overview of KPV, GHK-CU, BPC-157, TB-500 (Klow)
Each peptide acts through a distinct molecular pathway: BPC-157 upregulates VEGF and nitric oxide signaling to accelerate tissue repair; TB-500 binds actin to promote cell migration and angiogenesis at injury sites; KPV suppresses NF-κB and pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) via melanocortin receptor activation and PepT1-mediated intracellular uptake; GHK-Cu activates metalloprotein pathways and drives gene expression programs governing collagen and elastin synthesis. Together these mechanisms address inflammation, vascular remodeling, and extracellular matrix reconstruction simultaneously.
primary applications
- Multi-modal healing addressing tissue through complementary pathways
- Enhanced tolerability with KPV versus GLOW formulation
- Single injection convenience factor
- Collagen stimulation and tissue regeneration

BlendKPV, GHK-CU, BPC-157, TB-500 (Klow) Protocols
Subcutaneous injection is the primary delivery route for the KLOW blend, providing systemic distribution of all four peptides — GHK-Cu, BPC-157, TB-500, and KPV. Inject into abdominal fat or near the target injury site; the standard 80 mg vial is reconstituted with 2–3 mL bacteriostatic water and administered on a loading-then-maintenance schedule across 8–12 weeks.
| Goal | Dosage | Frequency | Route |
|---|---|---|---|
| Accelerate tissue repair immediately after acute injury or surgery with aggressive daily dosing for the first two weeks | 4 | 1 day range | SubQ near injury site |
| Establish systemic peptide levels for musculoskeletal repair across weeks 1–4 with a weekday on, weekend off schedule | 4 | 5 week range | SubQ |
| Sustain repair signaling and collagen remodeling during weeks 5–12 at a reduced injection frequency to lower cumulative dose burden | 4 | 3 week range | SubQ |
| Suppress persistent systemic inflammation in chronic conditions such as autoimmune joint disease or long-term overuse injuries over an extended 12-week cycle | 4 | 1 day range | SubQ |
| Drive dermal collagen remodeling and skin elasticity improvement via GHK-Cu-dominant dosing sustained over a full 8–12 week cycle | 4 | 1 day range | SubQ abdomen or thigh |
| Provide low-frequency background support for immune modulation and NF-kB suppression between active repair cycles | 4 | 3 week range | SubQ |
Reconstitution Instructions
Materials needed:
Steps to reconstitute
- Remove the KLOW vial from the refrigerator and allow it to reach room temperature for 5–10 minutes before reconstitution
- Wipe the vial stopper with an alcohol swab and allow it to dry completely
- Draw 3 mL of bacteriostatic water into a sterile syringe
- Tilt the vial at an angle and inject the bacteriostatic water slowly down the inner glass wall — do not aim directly at the lyophilized powder
- Remove the syringe, then gently roll the vial between your palms for 30–60 seconds until the powder dissolves — never shake or vortex the vial
- Inspect the solution: it should be clear or very slightly blue-tinted from GHK-Cu copper; discard if cloudy or particulate matter is visible
- Label the vial with the reconstitution date and refrigerate immediately at 2–8°C; use within 28 days
- For each injection, draw 0.10 mL (10 units on an insulin syringe) to deliver the standard dose of approximately 2.5 mg GHK-Cu, 500 mcg BPC-157, 500 mcg TB-500, and 500 mcg KPV
- Wipe the injection site (abdomen, thigh, or near target injury) with an alcohol swab and allow to dry
- Pinch a fold of skin and insert the needle at a 45-degree angle into subcutaneous fat; inject slowly and steadily, then withdraw and apply gentle pressure without massaging
KPV, GHK-CU, BPC-157, TB-500 (Klow) Cycle
The KPV, GHK-CU, BPC-157, TB-500 (Klow) Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.
- Day 1-7
- Some users report inflammation reduction within days
- Week 2-4
- Wound healing effects may develop if they manifest
- Week 4-6
- Full cycle effects; assess response
- Week 0-0
- 2-4 weeks off between cycles recommended

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
