Enter your vial's composition and diluent volume to see what a single draw delivers of each component. In a blend you set one component's dose and the rest follow the fixed ratio — the stack itself is covered in the GLOW compound guide.
A GLOW vial holding 50 mg GHK-Cu + 10 mg BPC-157 + 10 mg TB-500 (70 mg total), reconstituted with 5 mL of bacteriostatic water, gives 10 mg/mL of GHK-Cu, 2.0 mg/mL of BPC-157 and 2.0 mg/mL of TB-500 — 100 mcg, 20 mcg and 20 mcg per unit respectively on a U-100 syringe. For a 500 mcg BPC-157 dose, draw the syringe to 25.0 units (0.25 mL). That draw also delivers 2,500 mcg of GHK-Cu and 500 mcg of TB-500. At that dose the vial provides about 20 doses.
Defaults: the 50/10/10 mg composition sits inside the tested ranges on the GLOW compound page; 500 mcg of BPC-157 is an arithmetic example from the Wolverine calculator, not a GLOW dose. The widget calculates the BPC-157 share of the vial. The calculator picks the water so your dose lands on a line of your syringe — or set your own.

Not sure? Look at the biggest number printed on the barrel — 30, 50 or 100.
Check the box says U-100. Syringes for pet insulin (U-40) look the same but their lines measure 2.5× more liquid. This calculator is for U-100 syringes only.
One draw carries every compound.
Each line on this syringe = 2 units = 100 mcg of BPC-157.
| Peptide | Vial amount | Concentration | Dose per draw | Doses from vial |
|---|---|---|---|---|
| GHK-Cu | 50 mg | 25,000 mcg/mL | 2.5 mg | 20 |
| BPC-157 ★ | 10 mg | 5,000 mcg/mL | 500 mcg | 20 |
| TB-500 | 10 mg | 5,000 mcg/mL | 500 mcg | 20 |
Two GLOW compositions are in circulation and neither is a typo. The compound page describes 50 / 10 / 10 mg — GHK-Cu, BPC-157, TB-500, 70 mg total — and every tested vial on the platform sits inside that range (GHK-Cu typically 45–72 mg per tested vial). The site's general blend calculator carries a smaller 10 / 5 / 2 mg preset. The figures on this page describe the first.
| Composition | GHK-Cu | BPC-157 | TB-500 | Total |
|---|---|---|---|---|
| Compound page (this page's reference) | 50 mg | 10 mg | 10 mg | 70 mg |
| Blend-calculator preset | 10 mg | 5 mg | 2 mg | 17 mg |
Twenty-five units drawn from a 50 / 10 / 10 GLOW vial in 5 mL delivers 2,500 mcg of GHK-Cu, 500 mcg of BPC-157 and 500 mcg of TB-500. The identical twenty-five units drawn from a 10 / 5 / 2 vial in 2 mL delivers something quite different. Read your own vial's label before using any figure on this page.
This is the constraint that makes a blend different from three vials, and it is not a footnote. You choose a draw volume; every component in the vial arrives in that volume at its own concentration. Targeting one component sets the other two, whether or not those amounts are what you wanted.
| Draw at 5 mL dilution | Volume | GHK-Cu delivered | BPC-157 delivered | TB-500 delivered |
|---|---|---|---|---|
| 10 units | 0.10 mL | 1,000 mcg | 200 mcg | 200 mcg |
| 25 units (reference) | 0.25 mL | 2,500 mcg | 500 mcg | 500 mcg |
| 50 units | 0.50 mL | 5,000 mcg | 1,000 mcg | 1,000 mcg |
| 100 units (full barrel) | 1.00 mL | 10,000 mcg | 2,000 mcg | 2,000 mcg |
Arithmetic, shown: each component's concentration is its mass ÷ diluent volume, and a U-100 unit is 0.01 mL. Targeting 2,000 mcg of TB-500 in a 50 / 10 / 10 vial means drawing the full 100 units of a U-100 barrel and taking 10 mg of GHK-Cu with it — twenty times the TB-500 amount in mass — and it empties the vial in one draw. That is the practical ceiling a fixed ratio imposes.
The diluent volume sets every component's concentration at once, so pick it for the component you intend to dose by. 5 mL into a 70 mg vial puts BPC-157 and TB-500 at 2 mg/mL, where a 500 mcg amount is a readable 25 units. Technique is covered once, elsewhere: reconstituting peptides step by step and the bacteriostatic water guide.
Blends are left out of the COA benchmarks, which cover single vials. A blend certificate reports a whole-vial purity figure plus per-component net content — a different measurement, shown on the GLOW compound guide instead, with every GLOW lab test on file.
There is no price per milligram either, and that is deliberate. Two vials both labelled GLOW can hold very different amounts of each component, so dividing price by total mass compares products that are not comparable — a 50 / 10 / 10 vial and a 10 / 5 / 2 vial are different products. Tracked prices are grouped by composition and quoted per vial: GLOW vial prices by composition.
From a 50 / 10 / 10 mg vial in 5 mL — 2 mg/mL of BPC-157, 20 mcg per unit — 500 mcg is 25 units (0.25 mL). That same draw also delivers 2,500 mcg of GHK-Cu and 500 mcg of TB-500, because the ratio is fixed.
No. A blend vial has a fixed ratio: you choose a draw volume, and every component in the vial arrives in that volume at its own concentration. If you need to vary one component independently, that requires separate vials, not a blend.
Two are in circulation. The compound page describes 50 / 10 / 10 mg (GHK-Cu / BPC-157 / TB-500, 70 mg total), which every tested vial sits inside; the blend-calculator preset is 10 / 5 / 2 mg. Check your own vial's label — the figures on this page describe the first.
Because it would be meaningless. Two vials both labelled GLOW can hold very different amounts of each component, so dividing price by total mass compares products that are not comparable. Blend prices are grouped by composition and quoted per vial instead.
