GLOW Peptide UK: Compare Blends by Composition

What's in a GLOW blend?

"GLOW" is a supplier label, not a standard formula. Most UK listings combine three research peptides:

• GHK-Cu — the copper-binding tripeptide
• BPC-157 — the gastric-protein-derived pentadecapeptide
• TB-500 — a thymosin beta-4 fragment

KLOW adds KPV as a fourth component.

Why two GLOW vials can differ

• Different ratios. GHK-Cu often makes up most of the total mass, but the proportions vary.
• Different totals. A "70 mg" vial is a combined total, not 70 mg of each.
• Different TB-500 definitions. Some suppliers use a fragment, others the full-length protein.
• Different formats. GLOW is sold as lyophilised vials, and some suppliers also offer pens or serums.

How to compare GLOW listings

1. Get the per-component milligrams from the label or certificate of analysis.
2. Check that the CoA covers all three components, with identity confirmed for each.
3. Price it against the singles. Add up what each component would cost separately at its own price per mg. See the GLOW Blend comparison page for current listings.
4. Compare like-for-like formats — vial against vial, pen against pen.

Our detailed peptide blends guide works through an example.

The research behind each component

No published studies examine the GLOW combination as a whole. Each component has its own preclinical literature:

• GHK-Cu research overview
• BPC-157 research overview
• TB-500 and thymosin beta-4

Research use only

GLOW blends are third-party products for in-vitro laboratory research. They are not cosmetics, supplements or medicines, and are not for human or veterinary use. PeptideCompare gives no dosing or usage guidance.
