GLOW blend dosage

GLOW is one vial of GHK-Cu, BPC-157 and TB-500. The common 70 mg vial is 50 mg GHK-Cu plus 10 mg each of BPC-157 and TB-500. People mix it to 20 mg/mL and inject 10 to 20 units a day, which is 1.4 to 2.9 mg GHK-Cu and about 290 to 570 mcg each of BPC-157 and TB-500. The blend has never been studied; those numbers are the common solo doses of each peptide, locked into a 5:1:1 ratio.

How often: once daily, 5 to 7 days a week
When: any time; many inject in the evening near the area they want to treat
How long: 4 to 8 weeks, then 4 weeks off

GLOW blend dose to units chart

70 mg vial + 3.5 mL bacteriostatic water = 20 mg/mL (200 mcg per unit on a U-100 insulin syringe). 70 mg + 3.5 mL = 20 mg/mL total peptide, so 2 mg of blend = 0.1 mL = 10 units, carrying 1.43 mg GHK-Cu, 286 mcg BPC-157 and 286 mcg TB-500. With 2 mL instead (35 mg/mL), 10 units is 2.5 mg GHK-Cu and 500 mcg of each. A 50 mg GLOW vial has a different split; read the label before you do the math.

Dose	mL	Units (U-100)	Doses per vial
2 mg	0.1	10	35
2.5 mg	0.13	12.5	28
4 mg	0.2	20	17
5 mg	0.25	25	14

Side effects

injection site redness, bumps and a blue tint from the copper
fatigue or headache (reported)
nausea (reported)

Before you start. No study has tested the combination. GHK-Cu makes up most of the mass, so the BPC-157 and TB-500 doses are modest unless you push the total high. BPC-157 and TB-500 evidence is mostly animal work. People with copper metabolism problems should avoid it. Not medical advice. Talk to a clinician and start low.

GLOW blend dosage questions

GLOW peptide dosage?

Community use is 10 to 20 units a day of a 70 mg vial mixed with 3.5 mL (20 mg/mL): 1.4 to 2.9 mg GHK-Cu and about 290 to 570 mcg each of BPC-157 and TB-500. Start at 10 units and hold for a week before going up.

How much bacteriostatic water for GLOW 70 mg?

3.5 mL gives 20 mg/mL and round numbers (10 units = 2 mg of blend). 2 mL is the other common choice, 35 mg/mL, where 10 units = 2.5 mg GHK-Cu and 500 mcg each of the other two. More water means more units per dose and less sting.

GLOW vs KLOW?

Same three peptides; KLOW adds 10 mg of KPV for the gut and skin inflammation angle. If you want KPV at its own dose, buying it separately gives you control the fixed ratio does not.

Is GLOW safe to inject daily?

Nobody has tested the blend in people. The components are injected daily by many users with mostly injection site complaints. Rotate sites, keep the cycle to 4 to 8 weeks and stop if you get lumps that do not resolve.
