KLOW Stack Dosage Calculator

Enter your vial's composition and diluent volume to see what a single draw delivers of all four components. In a blend you set one component's dose and the rest follow the fixed ratio — the stack itself is covered in the KLOW compound guide.

A KLOW vial containing 50 mg GHK-Cu, 10 mg BPC-157, 10 mg TB-500 and 10 mg KPV — 80 mg in total — reconstituted with 4 mL of bacteriostatic water gives 20 mg/mL overall: 12.5 mg/mL of GHK-Cu at 125 mcg per unit on a U-100 syringe, and 2.5 mg/mL of each of the other three at 25 mcg per unit. To take 2 mg of GHK-Cu, draw the syringe to 16 units (0.16 mL). That same draw also delivers 0.4 mg of BPC-157, 0.4 mg of TB-500 and 0.4 mg of KPV, because in a blend you can only set the dose of one component — the rest follow the fixed ratio. At that draw the vial provides about 25 doses.

Which KLOW vial do you actually have?

Two KLOW compositions are in circulation and neither is a typo. The compound page describes 50 / 10 / 10 / 10 mg — GHK-Cu, BPC-157, TB-500, KPV, 80 mg total — which is the range tested vials sit inside. The site's general blend calculator carries a much smaller 10 / 5 / 2 / 5 mg preset, 22 mg in total. The figures on this page describe the first.

The second vial is not a rounding of the first: it holds roughly a quarter of the mass in a different ratio, so a draw calculated from this page would deliver far less of every component. Read your own vial's label first, then enter its numbers in the calculator above.

In a blend you can only set one component's dose

This is what separates a blend from four vials. You choose a draw volume; all four components arrive in that volume at their own concentrations. Targeting one sets the other three, whether or not those amounts are what you wanted — and with four components the chance that all four land where you would have put them is small.

Arithmetic, shown: each concentration is that component's mass ÷ diluent volume, and a U-100 unit is 0.01 mL. Because GHK-Cu is five times the mass of each other component, it is five times the amount in every draw — reaching 2.5 mg of KPV means drawing the full barrel and taking 12.5 mg of GHK-Cu with it. A fixed ratio is a ceiling as much as a convenience.

How to reconstitute a KLOW vial

The diluent volume sets all four concentrations at once, so choose it for the component you intend to dose by. 4 mL into an 80 mg vial puts GHK-Cu at 12.5 mg/mL, where a 2 mg amount is a readable 16 units. Technique is covered once, elsewhere: reconstituting peptides step by step and the bacteriostatic water guide.

Why this page has no purity index value and no price per milligram

Blends are excluded from the Purity Index, which measures single compounds. A blend certificate reports a whole-vial purity figure plus per-component net content — a different measurement, shown on the KLOW compound guide instead.

There is no price per milligram either. An 80 mg vial and a 22 mg vial both labelled KLOW are different products, so dividing price by total mass compares things that are not comparable — a blend price is only meaningful beside the milligrams of each component it contains. There is no KLOW price page yet: prices for a blend have to be grouped by composition before they mean anything, and that grouping is not published for KLOW.

Frequently asked questions

How many units is a 2 mg GHK-Cu dose from a KLOW vial?

From a 50 / 10 / 10 / 10 mg vial in 4 mL — 12.5 mg/mL of GHK-Cu, 125 mcg per unit — 2 mg is 16 units (0.16 mL). That same draw also delivers 0.4 mg each of BPC-157, TB-500 and KPV.

Can I dose one component of KLOW without the others?

No. A blend vial has a fixed ratio: you choose a draw volume, and all four components arrive in that volume at their own concentrations. Varying one independently requires separate vials, not a blend.

What is the difference between KLOW and GLOW?

KLOW is GLOW with KPV added — GHK-Cu, BPC-157 and TB-500 plus a fourth component. The GLOW calculator covers the three-component version; the arithmetic here is the same with one more line.

What composition is a KLOW vial?

Two are in circulation. The compound page describes 50 / 10 / 10 / 10 mg (GHK-Cu / BPC-157 / TB-500 / KPV, 80 mg total); the blend-calculator preset is 10 / 5 / 2 / 5 mg (22 mg total). Check your vial's label — the figures on this page describe the first.

Why is there no price per milligram for KLOW?

Because an 80 mg vial and a 22 mg vial both labelled KLOW are different products. Dividing price by total mass compares things that are not comparable. A blend price only means something grouped by composition and quoted per vial, and that grouping is not published for KLOW, so there is no KLOW price figure here at all.

Compounds discussed may be investigational and not approved for human use. Consult a qualified healthcare provider. Peptigrity is an independent review platform and does not sell, endorse or recommend specific products or vendors. None of KLOW's four components is approved by the FDA for human use. In a blend vial the component ratio is fixed: setting one component's amount sets the other three, and this page shows what each draw delivers rather than recommending any of them.
