KLOW dosage: what you can work out, and what nobody can tell you

You want a number: how much KLOW per shot. Here is the honest position. Nobody can source one, and this page will not invent one. What we can do is show you exactly what your own vial contains, and let you split it however you decide.

That sounds like a dodge until you see what the alternative looks like. So the second half of this page is three specific mistakes that appear on nearly every KLOW dosage guide we opened — with the arithmetic worked out, so you can check us.

Why no one can give you a KLOW dose

Four reasons, and none of them are going away:

1. There is no label. KLOW is not an approved product. No manufacturer filed anything, so there is no dosing section to read. Compare that with EGRIFTA SV, an approved peptide, where the exact volume is printed on an FDA label.
2. No study has looked at these four together. Not in humans, not in animals. The papers we cite each studied one ingredient on its own. The six papers, and what each actually tested.
3. Your vial may not be our vial. The 50 / 10 / 10 / 10 mg split is what independent community sources agreed on. It is not a spec. A different supplier can fill a different ratio and still call it KLOW.
4. The schedules in circulation trace back to each other. We followed several week-by-week KLOW protocols back looking for a source. They cite other sites, which cite other sites. There is no bottom.

So when a page hands you “weeks 1–2: 7.5 units, weeks 3–4: 15 units”, understand what you are reading. Not a protocol — somebody's guess, typed confidently.

What you can work out exactly

This part is not guesswork, it is division. An 80 mg vial holds a fixed amount of each ingredient. You choose how much water to add and how much to draw. Everything else follows.

Say you add 3.0 mL of bacteriostatic water and draw 0.075 mL. Here is what comes up the needle:

GHK-Cu 50 mg ÷ 3.0 mL × 0.075 mL = 1.25 mg
KPV, BPC-157, TB-500 — 10 mg each ÷ 3.0 mL × 0.075 mL = 250 mcg each
Total per draw: 2.0 mg · the vial gives you 40 draws

Change either number and everything moves with it, in one direction, predictably. More water means a bigger draw for the same milligrams. Fewer draws means more per draw. There is no hidden variable. Put your own numbers in.

What we will not do is pick the draw for you. That is the one step in this chain that needs evidence rather than arithmetic, and the evidence does not exist.

Three things other KLOW dosage pages get wrong

These are not style complaints. Each one changes the number that ends up in the syringe.

1. “7.5 units” means nothing until you say which syringe

Guides print draws in units. Units are not a fixed amount of liquid — they depend on the barrel:

0.075 mL on a U-100 syringe = 7.5 units
0.075 mL on a U-40 syringe = 3 units
Read “7.5 units” on a U-40 barrel and you draw 0.1875 mL — 2.5× the intended volume.

Not one of the KLOW guides we opened said which barrel its numbers assumed. They all assume U-100 and never write it down.

This exact error is documented on an FDA label, because it keeps happening to people who do have a prescription and a pharmacist. HUMULIN R U-500 (DailyMed) is required to print:

Use only a U-500 insulin syringe with HUMULIN R U-500 to avoid administration errors… If you use the wrong syringe, you can give yourself a 5 times overdose

Theirs is 500 ÷ 100 = 5×. Yours is 100 ÷ 40 = 2.5×. Same mistake, smaller multiplier, and no pharmacist in the loop. How to tell which barrel you are holding.

2. 10 mg of KPV is not 10 mg of KPV

KPV ships as a trifluoroacetate salt. The peptide is only part of that weight:

Free peptide 342.4 ÷ salt 456.5 g/mol = 75%
A vial labelled 10 mg by salt weight holds about 7.5 mg of KPV
So a “250 mcg” draw is really about 187 mcg of peptide

That is a 25% gap, and no KLOW guide we opened mentions it. Nothing on an unbranded vial tells you which one your supplier weighed, so we do not convert on your behalf — we do the arithmetic on the number you type in and tell you this is happening. The full KPV arithmetic.

3. Nobody checks whether it dissolves

Guides list 2.0 mL, 3.0 mL and 4.0 mL as if all three are equally fine. For GHK-Cu they are — at 3.0 mL it sits at 16.7 mg/mL against a sourced ceiling of 50 mg/mL, comfortably under.

For KPV, nobody knows. The only figure we could find is a qualitative band: “sparingly soluble, 1–10 mg/mL” in PBS, which is a lab salt solution, not water. Take the bottom of that band seriously and 10 mg of KPV would need 10 mL to dissolve — more than the vial holds, and three times what every guide recommends.

We are not claiming your KPV fails to dissolve. We are saying nobody has measured it, so nobody can tell you either way — and a page that prints 2.0 mL without raising it has not checked. That is why the KLOW calculator will not pick a water volume for you: picking one means choosing the end of that range that makes the feature work.

The one number we will not print

Milligrams per injection. Not to be coy — because writing it down would mean making it up, and it would then get copied onto the next site, the way the numbers we went looking for got copied onto this one.

Everything else on this page is checkable. Every figure the calculators use names its source and its grade, including the ones we could not find. How we grade every figure.

Work out your own vial — you supply the water and the amount per draw, and it tells you which line on your syringe that lands on.
