GLOW Peptide Reconstitution & Dosage Calculator
Use this GLOW peptide calculator for blend reconstitution and dosage arithmetic, not to choose an amount. GLOW here means GHK-Cu + BPC-157 + TB-500. The editable example contains 50 mg GHK-Cu + 10 mg BPC-157 + 10 mg TB-500, totaling 70 mg per vial. These component amounts occur in our catalog, but vendors and batches sell different ratios. Replace every component's mg with your own label; do not copy a kit's combined mass into a single-vial field. Presets, water volumes and example draws are mathematical illustrations, not preparation or dosing recommendations.

How to use the peptide calculator
- Enter the labeled mg of each GLOW component separately. All 3 fields are editable because the blend name does not specify one universal ratio.
- Enter the shared water volume in mL, then an arbitrary total blend amount in mg to convert.
- Read the total vial mass, concentration, draw volume and U-100 syringe markings. The displayed total dose is combined mass, not each component's mass.
- Check the per-component amounts. Their sum must equal the entered total; changing a draw scales all components together.
The reconstitution formula
Total vial mass (mg) = sum of the entered component masses.
Total concentration (mg/mL) = total vial mg ÷ water mL. Draw volume (mL) = entered total dose mg ÷ total concentration; U-100 units = mL × 100.
Each component per dose (mg) = its vial mg ÷ water mL × draw volume mL. Its mass fraction is component mg ÷ total vial mg.
Worked examples
70 mg labeled blend with an entered 2 mL
For 50 mg GHK-Cu + 10 mg BPC-157 + 10 mg TB-500, total concentration is 70 ÷ 2 = 35 mg/mL. A hypothetical 0.1 mL draw is 10 U-100 units and contains 3.5 mg total: 2.5 mg GHK-Cu, 0.5 mg BPC-157, 0.5 mg TB-500.
Same vial with an entered 4 mL
Concentration becomes 17.5 mg/mL. To represent the same arbitrary 3.5 mg total requires 0.2 mL, or 20 U-100 units. Component amounts are unchanged; doubling water halves concentration and doubles the corresponding volume.
Frequently asked questions
Do all GLOW vials have the same composition?
No. Enter the individual label amounts. Catalog GLOW listings share the three component names here but have different masses and ratios. Supplier headline totals can disagree with listed amounts; the calculator sums your entries rather than assuming the headline is correct.
How does the GLOW dosage calculator divide a total dose?
Multiply the total entered amount by each component's mass fraction. Water volume changes concentration but cannot change a fixed vial's component ratio. The result is arithmetic, not a recommendation or evidence that components can be combined safely.
How many units is 0.1 mL?
On a U-100 syringe, 0.1 mL × 100 = 10 units. These markings describe volume, not milligrams or a substance's biological activity.
How do I convert micrograms to milligrams?
1,000 mcg equals 1 mg. Divide a microgram amount by 1,000: for example, 250 mcg is 0.25 mg. Use matching mass units when dividing by concentration.
Are the examples dosing recommendations?
No. Every example and table entry is hypothetical arithmetic. The calculator converts quantities you supply; it does not determine an appropriate amount, frequency, route, or treatment.
Are syringe units IU?
No. U-100 markings measure volume, not biological International Units (IU).
