Also called: KLOW 80mg

By The Health Stacks Research TeamUpdated September 19, 2026

KLOW is a blend made of four small protein-like pieces called peptides. The parts are named GHK-Cu, BPC-157, TB-500, and KPV. It is sold as a white powder in a small bottle for scientists to study in the lab. It is not a medicine and is not approved by the FDA for people or animals.

Scientists look at each part of this blend for different reasons. One part is studied for skin and wound care, one for protecting the stomach, one for helping cells move and repair, and one for calming inflammation. Together, researchers think these pieces might help with healing and repair. But most of these ideas come from lab and animal studies, not from careful tests in people.

There is a lot we still do not know. No one has proven that the blend is safe or works in humans. Mixing four peptides together has not been well studied either. The powder must be kept very cold and used only by trained researchers in a lab. Anyone considering it for their own body should know it is not approved, and its safety is unknown.

Research-stageEarly-stage — evidence so far is mostly cell, animal, or preliminary human studies. Not an approved medicine. No rating yetWe don't yet have enough traceable, scored evidence to rate this peptide's sourcing. Check back as the research base grows.

The evidence

What the research says about each peptide in KLOW

A blend is only as studied as its parts. The reported findings below come from each peptide’s own research — grouped by compound so you always know which one a finding belongs to, and every claim links to the source it came from.

General

  • 500 mcg each of TB-500, BPC-157 and KPV + 2.5 mg GHK-Cu once daily SC (range 250–750 mcg each) 60/100Rated 60/100Source typeSpecialist communityIndependent sources1Every claim links to the page it came from, and stronger sources rate higher. Full methodology →↗ source
    1. Weeks 1–2 — TB-500: 250 mcg | BPC-157: 250 mcg | KPV: 250 mcg | GHK-Cu: 1.25 mg · 7.5 units (0.075 mL)
    2. Weeks 3–4 — TB-500: 500 mcg | BPC-157: 500 mcg | KPV: 500 mcg | GHK-Cu: 2.5 mg · 15 units (0.15 mL)
    3. Weeks 5–8 — TB-500: 750 mcg | BPC-157: 750 mcg | KPV: 750 mcg | GHK-Cu: 3.75 mg · 22.5 units (0.225 mL)
    4. Weeks 9–12 (Maintenance) — TB-500: 500 mcg | BPC-157: 500 mcg | KPV: 500 mcg | GHK-Cu: 2.5 mg · 15 units (0.15 mL)

mg vs mcg: one milligram (mg) equals 1,000 micrograms (mcg) — multiply by 1,000 going from mg to mcg, divide by 1,000 going from mcg to mg. Mixing the two up is a thousand-fold dosing error: 1 mg taken instead of 1 mcg is a 1,000× overdose; 1 mcg instead of 1 mg is a 1,000× underdose. Always double-check the unit label and the decimal place.
