KLOW Blend (GHK-Cu + BPC-157 + TB-500 + KPV)

In plain English

KLOW is the GLOW blend (GHK-Cu, BPC-157 and TB-500) with KPV added. KPV is a tiny anti-inflammatory peptide, so the blend is aimed at people who want the healing and skin effects plus calmer inflammation and gut support.

What it's used for

  • Skin quality and collagen
  • Injury healing and recovery
  • Inflammation
  • Gut health

Benefits

Each peptide has its own research, mostly in laboratory and animal studies; KPV has calmed gut inflammation in animal studies. Users report the benefits of GLOW with less inflammation and better digestion.

How it works

In simple terms: GLOW’s repair and skin effects, plus KPV to calm inflammation.

KPV is the last three amino acids of α-MSH and reduces inflammatory signaling inside cells. See the individual entries for each peptide.

Development history

  • 2020s: Introduced as an extended version of GLOW.

Typical protocols

Educational information only, not medical advice. The information below describes how this peptide has been used in research, on prescription labels or by users. It is not a recommendation. Talk to a qualified healthcare professional before starting, stopping or changing anything.

These ranges are what users commonly report. A common vial is 80 mg: 50 mg GHK-Cu, 10 mg BPC-157, 10 mg TB-500 and 10 mg KPV.

Use Total blend dose Frequency Length
Skin, healing and gut About 1.5–2.5 mg of the blend Daily 4–8 weeks

Cycling

Commonly run for 4–8 weeks, then a break.

Administration options

Subcutaneous injection.

Reconstitution and dosing calculator

An 80 mg vial is often mixed with 3–4 mL of bacteriostatic water. For a blend, enter the total mg in the vial and the total dose you want. The calculator then gives the units for the whole mix.

1Peptide in the vial

The total amount printed on the vial label.

2Bacteriostatic water added

More water makes each dose a bigger, easier-to-measure draw. It does not change how much peptide is in the vial.

3Dose per injection

Use the dose from your protocol or your clinician. 1 mg = 1,000 mcg.

4Your syringe

All three are U-100 insulin syringes: 100 units = 1 mL. Smaller barrels make small doses easier to read.

    Side effects and safety

    • Injection-site stinging or redness from the copper.
    • People with active cancer are usually advised to avoid healing peptides that promote new blood vessel growth.
    • People with Wilson's disease should avoid copper peptides.
    • Avoid during pregnancy and breastfeeding.

    Common stacks

    Usually used on its own, since it is already a stack.

    Storage

    Powder: refrigerate or freeze. After mixing: refrigerate at 2–8 °C and use within about 3–4 weeks.

    Compare with

    • GLOW: the same without KPV.
    • Wolverine: BPC-157 and TB-500 only.

    Frequently asked questions

    GLOW or KLOW?

    KLOW adds KPV, which users choose when inflammation or gut issues are part of the goal.
