KLOW vs Glow: what is actually different
One ingredient and 10 mg. That is the entire difference.
Both are community blends rather than branded products, so composition varies by supplier. The figures below are the ones that were consistent across the sources we checked.
What is in the vial
- Glow — 70 mg: GHK-Cu 50 mg · BPC-157 10 mg · TB-500 10 mg
- KLOW — 80 mg: GHK-Cu 50 mg · KPV 10 mg · BPC-157 10 mg · TB-500 10 mg
KLOW is Glow plus 10 mg of KPV. The K in KLOW is the KPV. Everything else is identical, including the GHK-Cu that dominates both by mass.
What that means for dosing
Because GHK-Cu is 50 mg in both, a dose anchored to GHK-Cu behaves the same way in either vial. The practical difference is that the same draw from a KLOW vial delivers a slightly smaller share of every component, since the same volume of water is spread across 80 mg instead of 70 mg.
Why we auto-calculate Glow but not KLOW
The calculator picks a water volume by checking every component against its solubility ceiling. We have sourced figures for GHK-Cu, BPC-157 and TB-500. We could not source one for KPV, so on the KLOW page the automatic answer is switched off and you enter the water volume yourself. It is not a bug — we would rather leave a feature off than guess a number that determines a concentration.
