How many units is 2.33 mg of GLOW blend?

It depends entirely on how much water you added. In a 70 mg vial reconstituted with 3 mL, the concentration is 23.33 mg/mL, so 2.33 mg is 0.1 mL, which is 10 units on a U-100 insulin syringe. In the same vial with 1.5 mL of water it is 5 units, and with 4.5 mL it is 15 units.

How much bacteriostatic water for a 70 mg GLOW blend vial?

3 mL is the usual choice. It gives 23.33 mg/mL, which puts the commonly reported range of 1 mg to 5 mg between roughly 4.3 and 21.4 units. Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.

How many doses are in a 70 mg vial?

Divide 70 by your dose. At 2.33 mg that is 30 doses, which at once daily is 30 days.

How many units of GLOW per day?

Reports cluster at 10 units a day from a 70 mg vial reconstituted with 3 mL, which is 2.33 mg of blend. With 2 mL of water the same 2.33 mg is about 7 units.

How much of each peptide is in a 10 unit draw of GLOW?

From 70 mg in 3 mL: about 1.67 mg GHK-Cu, 0.33 mg BPC-157 and 0.33 mg TB-500. The split is inferred from the 5:1:1 ratio on the label, not measured.

About the numbers above

GLOW is a pre-mixed vial sold by several vendors as 50 mg GHK-Cu, 10 mg BPC-157 and 10 mg TB-500, 70 mg in total. The three are in a fixed 5:1:1 ratio, so you cannot dose one without the others. None of the three is an approved medicine and the blend is sold for research use.

The dose most commonly reported is 10 units a day from a 70 mg vial reconstituted with 3 mL. That draw is 0.1 mL of a 23.3 mg/mL solution, which is 2.33 mg of blend: roughly 1.67 mg of GHK-Cu and 0.33 mg each of BPC-157 and TB-500. That is why the preset dose above is the odd-looking 2.33 mg. Reported cycles run about four weeks on and two to four off. The GLOW dosage chart page lists every combination of water and units.

What is in each draw

The vial is 50 mg GHK-Cu + 10 mg BPC-157 + 10 mg TB-500, a fixed 5:1:1 ratio. Every draw contains all of them in that proportion. Split below for 70 mg in 3 mL (23.33 mg/mL). The per-component figures are inferred from the label ratio, not measured.

Draw	Total blend	GHK-Cu	BPC-157	TB-500
5 units	1.167 mg	0.833 mg	0.167 mg	0.167 mg
10 units	2.333 mg	1.667 mg	0.333 mg	0.333 mg
15 units	3.5 mg	2.5 mg	0.5 mg	0.5 mg
20 units	4.667 mg	3.333 mg	0.667 mg	0.667 mg
25 units	5.833 mg	4.167 mg	0.833 mg	0.833 mg
30 units	7 mg	5 mg	1 mg	1 mg

A 70 mg vial at different water volumes

If the draw feels awkward to read, change the water rather than the dose. The dose stays the same; only the mark moves.

Vial	BAC water	Concentration	Draw	U-100 units	Doses/vial
70 mg	2 mL	35 mg/mL	0.067 mL	6.7 units	30
70 mg	3 mL	23.33 mg/mL	0.1 mL	10 units	30
70 mg	5 mL	14 mg/mL	0.166 mL	16.6 units	30

All rows above assume a 2.33 mg dose and a standard U-100 insulin syringe, where 100 units = 1 mL.

How long it stays in you

Not well characterised in humans. This site only draws a decay curve where a half-life is actually documented in humans, so there is none here. Treat any precise figure you see elsewhere for GLOW blend with suspicion.

Common questions

How many units is 2.33 mg of GLOW blend?: It depends entirely on how much water you added. In a 70 mg vial reconstituted with 3 mL, the concentration is 23.33 mg/mL, so 2.33 mg is 0.1 mL, which is 10 units on a U-100 insulin syringe. In the same vial with 1.5 mL of water it is 5 units, and with 4.5 mL it is 15 units.
How much bacteriostatic water for a 70 mg GLOW blend vial?: 3 mL is the usual choice. It gives 23.33 mg/mL, which puts the commonly reported range of 1 mg to 5 mg between roughly 4.3 and 21.4 units. Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.
How many doses are in a 70 mg vial?: Divide 70 by your dose. At 2.33 mg that is 30 doses, which at once daily is 30 days.
How many units of GLOW per day?: Reports cluster at 10 units a day from a 70 mg vial reconstituted with 3 mL, which is 2.33 mg of blend. With 2 mL of water the same 2.33 mg is about 7 units.
How much of each peptide is in a 10 unit draw of GLOW?: From 70 mg in 3 mL: about 1.67 mg GHK-Cu, 0.33 mg BPC-157 and 0.33 mg TB-500. The split is inferred from the 5:1:1 ratio on the label, not measured.

Read this before you use the numbers. This is a unit-conversion tool. It converts a vial strength and a volume of bacteriostatic water into a concentration, a draw volume and a mark on an insulin syringe. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most of the compounds listed here are sold for laboratory research use and are not approved for human use. Nothing on this site is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always confirm the strength printed on your own vial rather than trusting a preset.
