How much water a 70 mg GLOW vial takes, each component's concentration at 1 to 5 mL, units for a stated BPC-157 or GHK-Cu amount, and draws per vial.
GLOW is a pre-mixed vial of three peptides — GHK-Cu, BPC-157 and TB-500 — sold by its combined mass, usually 70 mg. Reconstituting it is the same act as for any vial, but the arithmetic runs three times, once per component, and the component a reader cares about decides how the reading is set. This page works the water volumes, the per-component concentrations and the readings for stated amounts. What the blend is and how it compares with KLOW are on this site's GLOW page and GLOW vs KLOW; the blend calculator works any other split.

This is the split stated on retail listings read on 2026-09-23 and on both protocol pages read on 2026-09-27. It is a claim about products, not a standard: no monograph or regulator defines "GLOW", and only an assay shows what a given vial holds.
Concentration at each water volume
Each component's concentration = its milligrams ÷ millilitres of water. One unit on a U-100 syringe is 0.01 mL.

The "total blend" figure some pages give — 23.3 mg/mL at 3 mL, 35 mg/mL at 2 mL — is the three columns added together. No component is present at that strength, so it cannot be used to read a syringe.
Setting the reading by one component
Every draw carries all three peptides in the fixed 5 : 1 : 1 ratio, so a reading chosen for one of them decides the other two.

Figures with a decimal fall between the 1-unit marks; at 1 mL the BPC-157 readings drop to 2.5 and 5 units, where one mark is 20–40% of the amount. More water spreads the same milligrams over more units, which is the only thing the volume changes. The per-compound figures in circulation for each peptide on its own are on the GHK-Cu, BPC-157 and TB-500 dosage pages; in GLOW they cannot be matched at once, because the blend fixes their ratio.
Two schedules, two volumes, nearly the same week
The two protocol pages read on 2026-09-27 state different water volumes and frequencies:
| Page (date) |

Per week |
| A (August 2026) |
3 mL |
10 units |
daily |
1.67 mg GHK-Cu, 333 mcg BPC-157, 333 mcg TB-500 |
11.7 mg GHK-Cu, 2.33 mg each other |
| B (2026-07-29), first phase |
2 mL |
10 units |
5 × a week |
2.5 mg GHK-Cu, 500 mcg BPC-157, 500 mcg TB-500 |
12.5 mg GHK-Cu, 2.5 mg each other |
| B, later phase |
2 mL |
10 units |
3 × a week |
same |
7.5 mg GHK-Cu, 1.5 mg each other |
Same "10 units", different milligrams per draw — 50% more on page B — yet weekly totals about 7% apart in the first phase. A reading quoted without its water volume is therefore not comparable between sources. Neither page cites a trial; no study of GLOW, or of any two of its components together, was found.

At 10 units a draw a vial gives 10 draws per millilitre, so page A's schedule uses a vial in about 30 days and page B's first phase in 4 weeks. The general mixing procedure is on Medibact's reconstitution how-to; the single-peptide arithmetic is on the GHK-Cu and BPC-157 reconstitution pages.
The arithmetic assumes the vial holds exactly the stated milligrams of each peptide and that all three dissolve fully at the chosen volume; neither is shown without an assay. It says nothing about whether GLOW, or any amount of it, does anything in people. Nothing on this page is a dose, a volume to use or a schedule. The compound guides for GHK-Cu, BPC-157 and TB-500 are on the Medibact store.
Sources and dates
Opened 2026-09-27: two GLOW protocol pages (one dated August 2026, one dated 2026-07-29), quoted for the split, water, draw and frequency they state; this site's GLOW vs KLOW page for the retail-listing split read 2026-09-23 and its PubMed census of the components. Per-component concentrations, readings, weekly totals and draw counts are arithmetic by this site. Corrections go to the contact page.
