KLOW Peptide Dosage Chart and 80 mg Blend Calculator
KLOW peptide dosage chart numbers are a split of one 80 mg vial, since nobody has published a human dose for KLOW. On 10 of the 13 pages we could read, the vial holds 50 mg of GHK-Cu plus 10 mg apiece of KPV, BPC-157 and TB-500. Nine of the 13 used 3 mL of bacteriostatic (bac) water as the main fill. The chart below shows what one syringe unit then carries.
One unit of an 80 mg KLOW vial
A unit of KLOW holds less of each part as the water goes up, because the same 80 mg is spread through more liquid. The chart lists the micrograms in one unit at four water volumes. The calculator does the same split for the label on your own vial.
The 2 mL mix is worked through on our KLOW protocol page, so it is not repeated here. What this page adds: a way to move a unit count from one water volume to another without changing the amount. The evidence for each peptide is in KLOW vs GLOW: the evidence.

80 mg KLOW blend calculator
It starts with the four-part split and the 3 mL fill from the chart. Change any part if your label differs, such as a vial with 15 mg of BPC-157. Then pick a part in the lower box to see how many units hold a set amount of it.
Your KLOW vial
Each box opens on the chart figures for an 80 mg KLOW vial, with 3 mL and 10 units, and none of them is a suggestion. Retype a number when your bottle shows another amount.

Disclaimer: these results are plain math on your inputs and are not a dose. Nobody has run a human trial of the four-part KLOW mix, so dosing is a decision for a licensed clinician.
The math trusts the label split and the water you typed. A real vial can hold more or less.
Work backwards from one part
Pick a part and type an amount in mcg. This field starts empty; the calculator does not suggest one.
The same calculator runs our GLOW chart, so both pages share one set of math. For one peptide at a time, try the peptide reconstitution calculator.

KLOW peptide dosage chart by bac water volume
We worked this chart out ourselves from the label split. Method: take each part in mg, multiply by 1000 for mcg, divide by the mL of water, then divide by 100 units per mL.
Our script split the 80 mg vial the way the KLOW guide on peptidedosingprotocols.com, a community site, lists it. One unit then holds:
| Water | mg per mL | GHK-Cu | KPV | BPC-157 | TB-500 | Total | 10-unit draws |
|---|---|---|---|---|---|---|---|
| 1 mL | 80 | 500 mcg | 100 mcg | 100 mcg | 100 mcg | 800 mcg | 10 |
| 3 mL | 26.67 | 166.7 mcg | 33.3 mcg | 33.3 mcg | 33.3 mcg | 266.7 mcg | 30 |
| 4 mL | 20 | 125 mcg | 25 mcg | 25 mcg | 25 mcg | 200 mcg | 40 |
| 5 mL | 16 | 100 mcg | 20 mcg | 20 mcg | 20 mcg | 160 mcg | 50 |
Disclaimer: this converts an 80 mg label into micrograms per unit. It sets no dose, and the four-peptide KLOW mix has never been tested in a human study.
KPV, BPC-157 and TB-500 always match each other, since each is 10 mg. GHK-Cu is five times any one of them. With 1 mL each unit is very strong, so small draws get hard to read.

What 13 KLOW pages said on 23 October 2026
We wanted to know how settled the KLOW recipe and the water volume really are. So on 23 October 2026 we opened 16 KLOW pages that rank in the US. 3 had been taken down. We read the other 13 and counted. We did not buy, sign up or fill in anything.
| What we looked for | Pages |
|---|---|
| Printed the 80 mg split as 50, 10, 10 and 10 mg | 10 of 13 |
| Gave a range instead (BPC-157 and TB-500 at 10 to 15 mg) | 1 of 13 |
| Used 3 mL as the main or starting fill | 9 of 13 |
| Said no trial has tested the four peptides together | 7 of 13 |
So 10 of the 13 pages we could read printed the same split, but it is still a seller recipe. One page described a ready-made 5 mL prescription product with a different strength per mL. Another was a reading guide that gives no mixing steps or unit counts. Six of the 13 never said that the blend is untested.
This is our own snapshot of one day, not a survey of every seller. Check your own label before you trust any chart, this one included.

How do you move a KLOW unit count to a new water volume?
Most KLOW unit counts online assume 3 mL. If you mixed with another volume, the same number of units holds a different amount. To keep the amount equal, multiply the units by your mL, then divide by 3. We ran that for every count the pages quoted.
KLOW websites quoted these unit counts for an 80 mg vial mixed with 3 mL (community practice, no trial):
7.5, 10, 15 and 20 units, which hold about 2, 2.67, 4 and 5.33 mg of blend
Disclaimer: these unit counts come from KLOW websites (community practice), not from any trial. They are not a dose for you or anyone else. KLOW itself has no published human dose.
Moving those community counts from the KLOW websites to other water volumes, with the amount held the same, gives:
| Quoted at 3 mL | Blend amount | Same amount at 1 mL | At 4 mL | At 5 mL |
|---|---|---|---|---|
| 7.5 units | 2 mg | 2.5 units | 10 units | 12.5 units |
| 10 units | 2.67 mg | 3.3 units | 13.3 units | 16.7 units |
| 15 units | 4 mg | 5 units | 20 units | 25 units |
| 20 units | 5.33 mg | 6.7 units | 26.7 units | 33.3 units |
Disclaimer: these unit counts come from KLOW websites (community practice), not from any trial. They are not a dose for you or anyone else. KLOW itself has no published human dose.
At 1 mL the smallest quoted count shrinks to a draw that is very hard to measure well. At 5 mL every count grows by two thirds. For the 2 mL version of this math, see the KLOW protocol page.

KLOW vs GLOW: what changes in each unit?
Both blends hold 50 mg GHK-Cu, so at the same water volume each unit carries the same GHK-Cu. KLOW then adds KPV on top.
With the community splits for both blends, as the peptidedosingprotocols.com guides give them, our own numbers for one unit are:
| Water | GHK-Cu, both | KLOW total | GLOW total | GHK-Cu share, KLOW vs GLOW |
|---|---|---|---|---|
| 3 mL | 166.7 mcg | 266.7 mcg | 233.3 mcg | 62.5% vs 71.4% |
| 5 mL | 100 mcg | 160 mcg | 140 mcg | 62.5% vs 71.4% |
Disclaimer: this converts an 80 mg label into micrograms per unit. It sets no dose, and the four-peptide KLOW mix has never been tested in a human study.
So a GLOW unit count used on a KLOW vial, at the same water, gives the same GHK-Cu plus the KPV. Our GLOW peptide dosage chart covers the three-part blend and its other vial sizes.

Do any of the four KLOW peptides have a human dose?
KPV, TB-500 and injected GHK-Cu have none. The FDA reports no data on people exposed to KPV through any route, and none for TB-500. For injected GHK-Cu it notes only limited human data. BPC-157 is the one part with any human numbers. A 2025 review found just three small pilot studies.
Two BPC-157 pilot reports name an amount (BPC-157 given alone, trial details, not KLOW):
2024, 12 women with bladder pain: 10 mg in total, injected around the bladder once
2025, 2 adults: 10 mg by drip, then 20 mg by drip a day later
Disclaimer: these come from two tiny BPC-157 studies with no control group, by drip or around the bladder. They are not KLOW amounts and not advice for anyone.
A 2025 systematic review of 36 BPC-157 studies found only 1 in people and no clinical safety data. None of this tells you about the four mixed together under the skin. Read more on the KPV profile and the BPC-157 profile.

Can you check KLOW math without the calculator?
Yes. Here is one example with 5 mL of water. On 23 October 2026 we typed the same numbers into the calculator, and it gave the same answers as our chart at 1, 3, 4 and 5 mL.
Worked example for a 10-unit draw, the count one community page quotes (community practice, no trial):
80 mg in 5 mL is 16 mg per mL
10 units is 0.1 mL, so the draw holds 1.6 mg of blend
GHK-Cu share: 50 mg in 5 mL is 10 mg per mL, so 0.1 mL holds 1000 mcg
KPV, BPC-157 and TB-500: 200 mcg each
Disclaimer: these unit counts come from KLOW websites (community practice), not from any trial. They are not a dose for you or anyone else. KLOW itself has no published human dose.
Add 1000 and three lots of 200 and you get 1600 mcg, which is the 1.6 mg draw. If the parts add back up, the math is right. The insulin syringe units chart turns any unit mark into mL.
Is KLOW legal, and what are the safety unknowns?
An openFDA search on 23 October 2026 found no FDA approval for KLOW or any of its four parts. The FDA compounding page says less than an approval ruling would. It names all four parts in its list of substances once in category 2, the group that “may present significant safety risks”, whose nominations were withdrawn. For BPC-157, injected GHK-Cu and TB-500, it says compounded forms “may pose risk” of immune reactions, tied to impurities, and for GHK-Cu and TB-500 to clumping too. For KPV it says it “lacks important information” on safety, including whether it would harm people.
There is also no maker label for KLOW, so no one has set a shelf life once it is mixed. Bac water itself is covered in what bac water is and bac water vs sterile water.

Common questions
How many units of KLOW peptide should I take?+
No study can answer that, because no human dose has been published for KLOW. Websites quote unit counts, but those are community practice. A unit count also means nothing without the water volume. The same count holds less at 5 mL than it does at 3 mL.
Is KLOW legal for human use?+
We found no FDA approval for KLOW or its four parts in openFDA on 23 October 2026. An FDA compounding page names all four in its list of substances once placed in category 2, the group that “may present significant safety risks”, whose nominations were later withdrawn. It reports no human exposure data it could find for KPV or for TB-500. The pages we read describe it as sold for research, not as a medicine. Local law differs by country.
What is the difference between KLOW and GLOW peptide?+
KLOW adds 10 mg of KPV to the GLOW recipe, so the vial grows from 70 to 80 mg. Each unit carries the same GHK-Cu at the same water volume. What changes is the total per unit, the extra KPV, and the share of GHK-Cu, 62.5 percent instead of about 71.4 percent.
How many units is 1 mL for peptides?+
A U-100 insulin syringe is marked so that 100 units make 1 mL, for any liquid. What changes from vial to vial is how many micrograms sit in each unit, which depends on the blend and the water. The chart and calculator on this page do that math.
How do you work out KLOW concentration?+
Divide the 80 mg in the vial by the water you add, in mL. For one part, use that part on its own instead of the full 80 mg. The chart below gives both results at four water volumes.
