Peptide Blends Explained: GLOW, KLOW and Wolverine

Blends — several peptides in one vial — are a fast-growing part of UK research catalogues. The names are marketing labels, not standards, which makes comparing them harder than comparing single peptides.

The common blends

Blend	Usually contains
Wolverine	BPC-157 + TB-500
GLOW	GHK-Cu + BPC-157 + TB-500
KLOW	GLOW + KPV
CJC-1295 / Ipamorelin	A GHRH analogue + a ghrelin-receptor agonist

"Usually" matters. Different suppliers use different ratios and total amounts, and sometimes different components, under the same name.

Why blends are hard to compare

• Ratios differ. A "GLOW 70 mg" vial from one supplier may split its contents very differently from another's.
• The headline mg is a total. Price per total mg can hide the fact that the most expensive component makes up only a small share.
• Analysis is harder. Testing several peptides in one vial is more complex, so blend CoAs are often less detailed.
• Nobody has studied the combinations. The research literature covers the individual components, not these specific blends.

How to compare a blend properly

1. Get the per-component amounts in milligrams from the label or CoA.
2. Check that the CoA covers each component — ideally with a separate HPLC peak and mass confirmation for each.
3. Price the blend against the singles. Add up what each component would cost bought separately at its price per mg. Sometimes the blend is cheaper; often it isn't.
4. Confirm sub-variants, such as whether the CJC-1295 in a blend has DAC. See our GH-axis guide.

Summary

Blend names don't guarantee composition. Compare blends on per-component content and documentation, and check them against the cost of buying single peptides. PeptideCompare provides no dosing or usage guidance, and nothing here is for human or veterinary use.
