Blends
Multi-Peptide Research Blends
A co-lyophilized blend is a single vial containing more than one compound, freeze-dried together. GLOW combines GHK-Cu, BPC-157 and TB-500; KLOW adds KPV to that set. The remaining blends in this category pair repair-model compounds in other ratios.
Blends are where verification gets genuinely harder, and it is worth understanding why. A purity figure on a multi-compound vial says nothing on its own about the ratio inside it: a blend can assay as highly pure material and still be weighted wrongly between its components. The only figure that answers the question is per-component mass, measured separately for each compound in the vial and compared against what the label claims.
That is the figure published for every blend batch here — not a single blended purity number, but the measured content of each component, on the certificate, linked to the batch code printed on the vial. The individual compound pages for each component are linked from every blend page for the underlying literature. Supplied strictly as laboratory research materials.

What to check before buying blends compounds
Purity is half the number. A purity figure tells you what fraction of the powder in the vial is the compound on the label — it tells you nothing about how much powder is in the vial. A lot can assay at 99.8% purity and still be short against its labelled content.
Both numbers are published for every batch here: purity from HPLC, and measured mass against expected content. Match the batch code printed on the vial to the certificate before you rely on either.
Blends research peptides — common questions
- Why does a blend not carry a single purity figure?
- Because purity is a property of one compound, not of a mixture. A blend certificate reports the identity and content of each component rather than one area-percent figure for the vial, which is why blend certificates look different from single-compound ones. A blend advertised with a single purity number has reported something that cannot be measured that way.
- What is the difference between GLOW and KLOW?
- One component. GLOW combines GHK-Cu, BPC-157 and TB-500; KLOW is the same three with KPV added. The component amounts are printed on the product page and on the certificate for the lot, so the composition is checkable rather than implied by the name.
- Is a blend cheaper than buying its components separately?
- Usually, because it is one vial and one fill rather than three or four. The trade-off is that the ratio is fixed at the point of manufacture, so a blend suits research where the published work uses the combination and single vials suit work that varies one component.
- How is a blend lot verified?
- Each component is identified and quantified by the independent laboratory, and the certificate reports the measured content per component against the labelled amount for that component. The lot code on the vial matches the lot code on that report.
