GLOW Peptide Calculator
This GLOW peptide calculator turns a dose of the blend, in milligrams of total blend, into the units to draw on a syringe. GLOW is not one compound. It is three, GHK-Cu, BPC-157 and TB-500, pre-mixed in a single vial, so the maths runs on the total: 70 mg in the standard vial. Enter the total on your label and the water you added, and get the exact draw, plus a table of what that draw delivers of each of the three.
Units measure volume, not dose. The same units on a different mix are a different dose.
The link holds only the numbers you typed. No account, no tracking, nothing else.

GLOW peptide calculator table: dose to units for the 70 mg vial
Three amounts of total blend, three mixes. One thing stands out next to the single-compound pages: how much powder is in this vial. Seventy milligrams is a lot, so at 1 mL of water the draws shrink to single figures, down where the marks on the barrel are hard to read. More water is what stretches a draw back to a readable size.
| Vial | Water | Concentration | 2.5 mg draw | 5 mg draw | 7 mg draw |
|---|---|---|---|---|---|
| 70 mg | 1 mL | 70 mg/mL | 3.6 units | 7.1 units | 10 units |
| 70 mg | 2 mL | 35 mg/mL | 7.1 units | 14.3 units | 20 units |
| 70 mg | 3 mL | 23.33 mg/mL | 10.7 units | 21.4 units | 30 units |
The concentration column is total blend per mL, all three compounds counted together, because that is what a draw is filled with. What the milligrams in a draw are made of is the next table's job.
One draw, three compounds
A total only tells half the story. The vial's 70 mg is split 50, 10 and 10: five parts GHK-Cu to one part each of BPC-157 and TB-500. Every draw keeps that proportion, so a draw sized for one compound quietly fixes the other two. This table sizes the draw by the GHK-Cu amount, in a vial mixed with 3 mL of water, and shows what rides along.
| GHK-Cu in the draw | Draw | BPC-157 it delivers | TB-500 it delivers |
|---|---|---|---|
| 2.5 mg | 15 units | 0.5 mg | 0.5 mg |
| 5 mg | 30 units | 1 mg | 1 mg |
| 7.5 mg | 45 units | 1.5 mg | 1.5 mg |
The pattern never changes: for every 5 mg of GHK-Cu in a draw there is exactly 1 mg of BPC-157 and 1 mg of TB-500, because that is the proportion in the powder. If your vial prints different amounts, run the same table for your own split on the peptide mixing calculator.
The ratio is fixed before the vial reaches you
With separate vials, every amount is your own decision, worked out one compound at a time. A GLOW vial removes that decision. The proportions were chosen when the powder was blended, before the vial was sealed, and no draw can undo them. You cannot change one compound in a blend without changing all three, because the draw is one liquid and the liquid is the blend.
That is the honest trade a blend vial makes. One vial and one draw instead of three, in exchange for giving up independent amounts. It is also why this page shows the per-compound table at all: if the amount a draw delivers of one compound is not the amount your numbers called for, that is a property of the vial, not a rounding error, and it is better seen in a table than discovered at the syringe.
The two components with their own pages here are the BPC-157 calculator and the TB-500 calculator, for anyone working with the separate vials instead.
Common questions
What is in a GLOW vial?
Three compounds, pre-mixed in one vial before it is sold. The standard fill is 50 mg of GHK-Cu, 10 mg of BPC-157 and 10 mg of TB-500, which is where the 70 mg total on the label comes from. GLOW is a blend name, not a single peptide, and the ratio between the three is set by whoever made the vial.
How many units is 5 mg of GLOW?
It depends on the water, as always. In the 70 mg vial mixed with 2 mL, 5 mg of total blend is 14.3 units. Mixed with 3 mL instead, the same 5 mg is 21.4 units, because the mix is weaker. The table above covers the common mixes, and the calculator works for any total you type in.
Can I get more BPC-157 without more GHK-Cu?
Not from a GLOW vial. The three compounds were blended in a fixed proportion before the vial was sealed, so every draw takes them in that same proportion. A bigger draw is more of all three, a smaller draw is less of all three. Amounts that move independently need separate vials, where each one is its own calculation.
My GLOW vial is not 70 mg. Can I still use this calculator?
Yes. Type the total printed on your own label, and the dose-to-units maths works the same, because it only needs the total and the water. One caution: the table on this page showing what a draw delivers of each compound assumes the standard fill, 50 mg of GHK-Cu with 10 mg each of BPC-157 and TB-500. If your vial prints a different split, the peptide mixing calculator works from the split directly.
Why is the powder blue?
The copper. GHK-Cu is a copper complex, and the copper tints the powder blue. It is the only compound on this site that changes the colour of what is in the vial, and the tint is how a lot of people recognise a GLOW vial before they read the label.
Is GLOW an approved medicine?
No. The blend is not approved by the FDA or any other medicines regulator, and neither are its parts in this form. BPC-157 sits in Category 2 of the FDA’s compounding list, the category for substances flagged as raising significant safety concerns. TB-500 is not an approved medicine. GHK-Cu is used as an ingredient in skin creams, which is a cosmetic use, not an approved injectable medicine. The methodology page records the position properly.
Arithmetic only
This calculator does maths on the numbers you enter. It works out concentration, draw volume and syringe units from the vial amount and water volume you give it. Nothing more.
It does not recommend amounts, schedules or products, and it does not know what is in your vial. It uses the amount printed on the label. If the label and the actual contents differ, the result differs too. For medical questions, talk to a clinician.
