BPC-157 Dosage Calculator: Reconstitution, mL and Units

BPC-157 Reconstitution Calculator

Convert BPC-157 amounts in mcg or mg into millilitres and units on a U-100 insulin syringe, for any vial size and water volume. The calculator is set to our BPC-157 10mg vial.

Reconstituting BPC-157

BPC-157 research amounts are usually written in micrograms, which is where most mistakes happen: 250 mcg is 0.25 mg, not 2.5 mg. The calculator converts mcg to mg for you before working out the volume. Our BPC-157 10mg vial is lyophilized and dissolves readily in bacteriostatic water; the chart below also covers the 5mg vials many protocols are written around.

BPC-157 is also supplied as 500 mcg capsules, which need no calculator: each capsule holds a fixed amount. For BPC-157 combined with TB-500 in one vial, use the BPC-157 and TB-500 blend calculator.

BPC-157 reconstitution chart

Concentration for each vial size and water volume. On a U-100 insulin syringe, 10 units is 0.1 mL and 100 units is 1 mL.

Vial	Bac water added	Concentration	Per 10 units (0.1 mL)	Per 1 unit
5 mg	1 mL	5 mg/mL	0.5 mg (500 mcg)	50 mcg
5 mg	2 mL	2.5 mg/mL	0.25 mg (250 mcg)	25 mcg
5 mg	3 mL	1.667 mg/mL	0.167 mg (166.667 mcg)	16.667 mcg
10 mg	1 mL	10 mg/mL	1 mg (1000 mcg)	100 mcg
10 mg	2 mL	5 mg/mL	0.5 mg (500 mcg)	50 mcg
10 mg	3 mL	3.333 mg/mL	0.333 mg (333.333 mcg)	33.333 mcg

The formula behind the calculator

concentration (mg/mL) = BPC-157 in vial (mg) ÷ water added (mL)

units on a U-100 syringe = amount (mg) ÷ concentration (mg/mL) × 100

Amounts in micrograms are divided by 1,000 first. The calculator does this arithmetic only; it does not recommend an amount, and BPC-157 from AminoBlend is supplied for laboratory research use only.

Buy BPC-157 Online Once the Numbers Work

With the concentration settled, buy the matching vial: the BPC-157 10mg vial is $69, and labs comparing oral formats can shop the 500 mcg capsules on the same page. Add bacteriostatic water to the order if the bench is out. Searching for BPC-157 near me rarely turns up a lab-grade source; ordering online from our Australian stock does, with the lot certificate readable first.

BPC-157 Calculator Explained

Reading the Four BPC-157 Calculator Outputs

The first figure is how many milligrams of BPC-157 sit in each millilitre once the vial is reconstituted. The mcg per 0.1 mL line is that strength multiplied by 100, the amount held between the zero mark and the 10 unit mark on a U-100 syringe. The last two outputs give the volume that contains your target microgram amount, first in millilitres and then in syringe units, where 1 mL equals 100 units.

A 250 mcg BPC-157 Target From the 10mg Vial

1 mL of diluent: 10 mg/mL and 1,000 mcg per 0.1 mL, so 250 mcg sits in 0.025 mL, which is 2.5 units.
2 mL: 5 mg/mL and 500 mcg per 0.1 mL, so 250 mcg is 0.05 mL, or 5 units.
3 mL: 3.333 mg/mL and about 333 mcg per 0.1 mL, so 250 mcg is 0.075 mL, or 7.5 units.
The BPC-157 capsules hold a fixed 500 mcg each and never pass through this calculator; only the 10mg vial does.

Why 3 mL Suits Small BPC-157 Aliquots

With 1 mL of water, a 250 mcg BPC-157 aliquot lands at 2.5 units, halfway between graduations and hard to judge by eye. Diluting the same 10mg cake to 3 mL stretches that mass across 7.5 units, three times the travel along the barrel, so a half-unit misreading costs proportionally less. A 0.3 mL U-100 syringe widens the spacing again for such short draws.

Turning BPC-157 Concentration Into Molarity

BPC-157 has a molecular weight of about 1,419.5 g/mol, so the 5 mg/mL stock made with 2 mL of water is roughly 3.5 mM. One micromolar of BPC-157 equals about 1.42 mcg per mL, which lets you convert a molar working concentration from a cell culture paper into a microgram target for the calculator. Compare against the mass reported for your lot in the COA library, since counter-ions in the powder add weight that is not peptide.

Where BPC-157 Arithmetic Usually Goes Wrong

Entering 250 in the mg box instead of the mcg box, which inflates the answer a thousandfold: 250 mcg is only 0.25 mg.
Treating 5 units as 5 mL; on a U-100 barrel, 5 units of BPC-157 solution is just 0.05 mL.
Typing the water you meant to add rather than the volume that actually went into the 10mg vial, which shifts every output.
Keying in the 500 mcg capsule strength as if it were a vial fill.

BPC-157 Calculator Questions

How much bacteriostatic water to mix with 10mg of BPC-157?

Any volume from 1 to 3 mL works in a standard vial. 2 mL is a common choice because it gives 5 mg per mL, so every 10 units on a U-100 syringe holds 500 mcg, which keeps the arithmetic simple.

How much bacteriostatic water to mix with 5mg of BPC-157?

Adding 1 mL gives 5 mg per mL and 2 mL gives 2.5 mg per mL. At 2.5 mg per mL, each unit on a U-100 syringe holds 25 mcg.

How many units is 250 mcg of BPC-157?

It depends on the concentration. At 5 mg per mL, 250 mcg is 0.05 mL, or 5 units. At 2.5 mg per mL it is 0.1 mL, or 10 units. Enter your own values in the calculator to check.

Is this a BPC-157 dosage recommendation?

No. The calculator only converts amounts into volumes. AminoBlend supplies BPC-157 for laboratory research use only and does not give dosing advice.
