TL;DR: A BPC-157 "dosage chart in units" is a conversion table, nothing more. Given the concentration of your reconstituted stock, it maps a target amount of peptide to marks on a standard U-100 insulin syringe, where 1 unit = 0.01 mL. Reference tables for 5 mg and 10 mg vials at common dilution volumes are below, in micrograms because that is the scale BPC-157 research uses. For any combination not listed, the peptide reconstitution calculator does the arithmetic instantly. These are concentration references for laboratory handling of a research material — not human dosing guidance.
How to Read a Units Chart
The word "dosage" in these searches is really shorthand for a units conversion, and that conversion has one input beyond the target amount: concentration. Concentration is the vial mass divided by the volume of diluent added. Once you have it, one fact about the syringe finishes the job.
On a standard U-100 insulin syringe the barrel is marked 0–100 units, and one unit equals 0.01 mL. So the peptide held in a single unit is the concentration in mcg/mL multiplied by 0.01. The units for any target amount are then just the target divided by that per-unit figure. Every chart below is that arithmetic applied across common values.
A units figure is meaningless on its own. "10 units of BPC-157" only specifies an amount once you also know the vial was reconstituted to, say, 5000 mcg/mL.
10 mg Vial Reference Charts
The BPC-157 10 mg vial is most often reconstituted with either 2 mL or 5 mL of diluent. Both are tabulated here.
10 mg vial · 2 mL diluent · 5000 mcg/mL (each unit = 50 mcg):
| Target amount | Draw volume | U-100 units |
|---|---|---|
| 100 mcg | 0.02 mL | 2 units |
| 250 mcg | 0.05 mL | 5 units |
| 500 mcg | 0.10 mL | 10 units |
| 750 mcg | 0.15 mL | 15 units |
| 1000 mcg (1 mg) | 0.20 mL | 20 units |
10 mg vial · 5 mL diluent · 2000 mcg/mL (each unit = 20 mcg):
| Target amount | Draw volume | U-100 units |
|---|---|---|
| 100 mcg | 0.05 mL | 5 units |
| 250 mcg | 0.125 mL | 12.5 units |
| 500 mcg | 0.25 mL | 25 units |
| 750 mcg | 0.375 mL | 37.5 units |
| 1000 mcg (1 mg) | 0.50 mL | 50 units |
The trade-off between the two is worth noticing. Going from 2 mL to 5 mL of diluent makes the same target amount two and a half times more units to draw. A weaker stock is easier to measure precisely, but each draw uses more volume.
5 mg Vial Reference Chart
Plenty of BPC-157 research uses 5 mg vials, so the same conversion at that fill is below.
5 mg vial · 2 mL diluent · 2500 mcg/mL (each unit = 25 mcg):
| Target amount | Draw volume | U-100 units |
|---|---|---|
| 100 mcg | 0.04 mL | 4 units |
| 250 mcg | 0.10 mL | 10 units |
| 500 mcg | 0.20 mL | 20 units |
| 750 mcg | 0.30 mL | 30 units |
| 1000 mcg (1 mg) | 0.40 mL | 40 units |
Why These Tables Are in Micrograms
Because that is the scale BPC-157 research works at. Amounts in the literature sit in the hundreds of micrograms, which is roughly a thousandth of the milligram amounts used in incretin research like our retatrutide dosage chart. Build a BPC-157 table in milligrams and every row becomes an awkward fraction. The arithmetic is identical, only the units change.
One conversion is worth memorising: 1 mg = 1000 mcg. It is the source of most errors people make reading these charts.
Where the Concentration Comes From
Every number above assumes the vial was reconstituted correctly and the resulting concentration is known. The full method — choosing a diluent, technique, and the concentration math — is in our guide to reconstituting BPC-157. Bacteriostatic water is the standard diluent for a vial that will be drawn from more than once; see the bacteriostatic water guide and the companion 30 mL BAC water.
Blends and Capsules Work Differently
Two cases the tables above do not cover.
Blends. A co-lyophilised vial like BPC/TB 10/10 mg holds two peptides, so one draw delivers both. The concentration has to be worked out per component, not for the vial as a whole. Our BPC-157 and TB-500 piece covers why the pairing is studied together.
Capsules. Capsule forms arrive at a fixed amount per capsule with nothing to reconstitute, so there is no concentration and no chart. This is the practical difference behind a lot of the oral-versus-vial search interest.
Use the Calculator for Anything Off-Chart
These tables cover the common setups. Any other vial size, diluent volume or target amount converts directly with the peptide reconstitution calculator, which also flags when a draw would overflow the syringe barrel you have selected.
A Note on "Dosage" Language
The tables above say "target amount" rather than "dose" on purpose. BPC-157 is supplied as a research material, and these charts are concentration references for laboratory handling — conversions between peptide mass and syringe units. They are not human dosing recommendations, and no route, schedule or human use is implied by them. Separately, no verified human safety profile exists for this peptide; our BPC-157 side effects piece explains why.
For Research Use Only
All figures above are reconstitution and concentration references for in-vitro and laboratory research. Helix North supplies BPC-157 and bacteriostatic water for research applications only — not for human or animal consumption, and not as dosing guidance.
