“Glow” blend is a common name for a combined vial of GHK-Cu (copper peptide) and BPC-157, sold together for convenience rather than as two separate compounds. Reconstituting a blend follows the exact same math as a single-compound vial — the label lists a total amount, and you divide that by however much liquid you add.
Why blends aren’t more complicated
Because both compounds are already combined in the vial before you add any liquid, you don’t need to calculate two separate concentrations. The vial’s total labeled amount (however the supplier expresses it) divided by your added liquid gives you one working concentration for the whole mixture.
Working through an example
Say a Glow blend vial is labeled at 50 mg total and you add 5 mL of bacteriostatic water. That’s a concentration of 10 mg/mL. If your target amount is 500 mcg, the calculator converts that into a liquid volume and syringe mark automatically — no separate math needed for each compound in the blend.
Use the calculator
Enter your specific vial amount and water added into the GHK-Cu + BPC-157 (Glow) calculator to get your exact concentration and syringe measurement.
