GLOW Reconstitution Calculator
For in vitro research use only · Not medical advice
Preset to a 70 mg GLOW vial in 3 mL of diluent. A 70 mg vial in 3 mL gives ≈23 mg/mL combined — about 16.7 mg/mL GHK-Cu, 3.3 mg/mL BPC-157 and 3.3 mg/mL TB-500. Use neutral or slightly alkaline diluent only; acid dissociates the copper.
GLOW reconstitution
Preset to a common GLOW vial size and diluent volume. Adjust any field for your own laboratory protocol.
A 70 mg GLOW vial reconstituted with 3 mL gives 23.333 mg/mL. Measuring 0.043 mL gives 1,000 mcg per portion — about 70 portions from the vial.
Choosing a diluent for GLOW
All three components are freely water-soluble and reconstitute together in a single diluent volume without difficulty. The solution is distinctly BLUE — GHK-Cu is 71% of the fill by mass, and its coordinated copper gives the whole preparation the same colour a pure GHK-Cu solution would have. That blue is a genuine integrity signal for the majority component. Critically, the copper chemistry means GLOW inherits GHK-Cu's pH constraint: never reconstitute in acidic diluent.
Handling notes for GLOW
- Never reconstitute in acidic diluent — this dissociates copper from the GHK-Cu component, which is the majority of the vial.
- Keep chelating agents such as EDTA out of any buffer used with GLOW; they will strip the copper.
- Treat colour as data: clear, even blue is correct. Pale, colourless or green means the GHK-Cu component has degraded.
- Protect from light for the TB-500 and GHK-Cu components, and minimise headspace exposure.
- Do not subdivide the dry cake — three co-lyophilized components do not partition evenly in powder form.
