How much water an 80 mg KLOW vial takes, each of its four peptides' concentration at 1 to 5 mL, the 'total blend' figures converted per peptide, and vial life.
KLOW is a pre-mixed vial of four peptides — GHK-Cu, BPC-157, TB-500 and KPV — sold by its combined mass, usually 80 mg. Reconstitution is the same act as for any vial, but the arithmetic runs four times, and protocol pages add a complication of their own: they quote draws as a "total blend" amount that no single component matches. This page works the water volumes, each component's concentration, the conversion of total-blend figures into per-peptide amounts, and how long a vial lasts on a stated schedule (read 2026-10-11). It reports; nothing here is a dose or a volume to use.
What the blend is, and how it differs from GLOW, are on this site's KLOW page and GLOW vs KLOW. The three-peptide version is worked on GLOW reconstitution; the pairing of KLOW's two smaller components, outside a blend, is on BPC-157 with KPV. The blend calculator works any other split.

This is the split stated on retail listings read on 2026-09-23 and assumed by the protocol page read on 2026-10-11. It is a claim about products, not a standard: no monograph or regulator defines "KLOW", this site's KLOW page records a minority of sources using the name for KPV with BPC-157 alone, and only an assay shows what a given vial holds.

The total-blend column is the four component columns added. It is the figure protocol pages quote, and it cannot be used to read a syringe for any one peptide.
The protocol page read on 2026-10-11 states 3 mL of water and gives its draws as total blend. Splitting each by the listed shares:

The rule is one line: GHK-Cu = total × 0.625; each of the other three = total × 0.125. The protocol page states the same per-peptide figures for 10 units, which confirms its arithmetic; its larger draws are converted here.
Setting the reading by one component
Every draw carries the four peptides in a fixed 5 : 1 : 1 : 1 ratio by mass, so a reading chosen for one decides the other three. Sized to an amount of BPC-157 (or KPV, or TB-500 — all three are 10 mg), units = amount in mcg × mL of water ÷ 100:
| Amount of one 10 mg component |
1 mL |

Stated as results: with 3 mL, 250 mcg of BPC-157 is 7.5 units; with 2 mL it is 5 units. Equal milligrams hide unequal molecule counts — KPV is small, so a draw holds about four KPV molecules per BPC-157 molecule — which is set out on the BPC-157 with KPV page. The single-peptide figures in circulation are on the GHK-Cu, BPC-157, TB-500 and KPV dosage pages; in KLOW they cannot be matched independently, because the blend fixes the ratio.
How long a vial lasts on a stated schedule
At 3 mL a vial holds 300 units. The protocol page's stated phases, as arithmetic:

The page's own estimates — two to three vials for 8 weeks, four to five for 16 — fit this arithmetic for 8 weeks (840 units, 2.8 vials); its 16-week estimate assumes a lower rate than its 20-unit final phase. The schedule is reported as the page states it; no trial of KLOW or of any two of its components together has been found, so the phases have no study behind them.

The arithmetic assumes the vial holds exactly the stated milligrams of each peptide and that all four dissolve fully at the chosen volume; neither is shown without an assay, and the dissolved powder itself adds a little volume, so dividing by the water slightly overstates every concentration. It says nothing about whether KLOW, or any amount of it, does anything in people. The general mixing procedure is on Medibact's reconstitution how-to; bacteriostatic water and the compound guides for GHK-Cu, BPC-157, TB-500 and KPV are on the Medibact store.
Sources and dates
Opened 2026-10-11: a KLOW protocol page stating the 80 mg split, 3 mL of water and a three-phase schedule in total-blend micrograms and units (quoted, not named, since this site names no seller other than Medibact). Carried from this site's pages with their read dates: the retail-listing split (GLOW vs KLOW, 2026-09-23), the molar comparison from PubChem molecular weights (GLOW vs KLOW, 2026-09-23; BPC-157 with KPV, 2026-10-10). Per-component concentrations, conversions, unit readings and vial counts are arithmetic by this site. Corrections go to the contact page.
