Reconstitution, dosing & half-life math — done right, in seconds.
GLOW Blend Reconstitution Calculator
GLOW Blend is a research blend of three peptides — GHK-Cu (50 mg), BPC-157 (10 mg) and TB-500 (10 mg), 70 mg total per vial. This page shows how to reconstitute it and read the result on a syringe — the calculator does the arithmetic for you.
Status: Research use only; not approved for human use.
The math
Concentration = vial ÷ water · Units = (dose ÷ concentration) × 100
GLOW is a fixed-ratio blend, so every draw contains all three peptides in the same 50:10:10 proportion. Enter the total 70 mg in the calculator; each draw then splits proportionally across the three components.
Worked example

Example
Vial70 mg
Bacteriostatic water3 mL
Concentration23.3 mg/mL
Each 10 units (0.1 mL) contains2,333 mcg
What each draw contains
Because GLOW Blend is a fixed-ratio blend, every draw carries all components proportionally. With the example above (vial in 3 mL), a 10-unit (0.1 mL) draw works out to roughly:
GHK-Cu: 50 mg in the vial → about 1,667 mcg per 10-unit draw
BPC-157: 10 mg in the vial → about 333 mcg per 10-unit draw
TB-500: 10 mg in the vial → about 333 mcg per 10-unit draw
How to use the calculator
Open the calculator and enter your GLOW Blend vial size.
Enter your bacteriostatic water volume, then your dose.
Add bacteriostatic water to the lyophilized vial to reach a concentration you can measure. For example, 70 mg in 3 mL of water gives 23.3 mg/mL, so each 10 units (0.1 mL) on a U-100 syringe contains about 2,333 mcg of GLOW Blend. Swirl gently rather than shaking.
How does reconstituting a blend like GLOW Blend differ?
GLOW Blend contains GHK-Cu 50 mg, BPC-157 10 mg, TB-500 10 mg (70 mg total) in a fixed ratio. Enter the total 70 mg in the calculator. Every draw contains all components in that same proportion, so a draw that is one-tenth of the vial holds one-tenth of each peptide.
How many units of GLOW Blend do I draw?
Divide your intended dose by the concentration to get the volume in mL, then multiply by 100 for a U-100 syringe. The calculator does this automatically once you enter your vial size, water volume and dose.
What vial sizes does GLOW Blend come in?
GLOW Blend is commonly supplied as 70 mg total (50 / 10 / 10). The amount in the vial does not change with how much water you add — water only sets the concentration.
Is GLOW Blend approved for human use?
Research use only; not approved for human use. This calculator only performs arithmetic on the numbers you enter and does not recommend any dose.
