What is a peptide blend?

A peptide blend combines two or more peptides in a single vial, sold under one name — GLOW, KLOW and CJC-1295 + Ipamorelin are common examples.

Why the label can mislead

A vial labelled "10 mg" may mean 10 mg of each component, or 10 mg total split between them. Those are very different products at the same price, and vendors are not consistent about which they mean. Always find the per-component breakdown before comparing.

How to compare a blend fairly

• Per-component mass. Work out the milligrams of each peptide, not the headline total.
• Price per mg of the component you actually care about. A blend can look cheap while the ingredient you want is a small fraction of the vial.
• The ratio is fixed. Both peptides share one vial and one diluent volume, so a single draw delivers both in whatever proportion the vendor chose. You cannot adjust one without adjusting the other.
• Documentation. A blend needs purity and identity testing for each component, not one certificate for the mixture.

Reconstitution

Each component has its own concentration derived from its own mass in the shared water volume. Pick the water volume so the component with the tighter requirement lands on a readable syringe mark; the other is then fixed by the ratio. The reconstitution calculator handles multi-peptide blends directly.
