Can I dose BPC-157 and TB-500 separately from a blend vial?

No. Both peptides are dissolved in the same liquid, so any volume you draw contains both in the ratio the vial was made at. A 5 mg + 5 mg blend always delivers them 1:1. If you need to vary one independently of the other, you need separate vials.

How many units is 250 mcg of BPC-157 from a 5 mg + 5 mg blend in 2 mL?

Each component is 2.5 mg/mL at 2 mL, so 250 mcg is 0.1 mL — 10 units on a U-100 syringe. That same 10 units also carries 250 mcg of TB-500, because both share the volume.

Does the total blend concentration or the per-component concentration matter?

Both, for different questions. The total (5 mg/mL for a 5 mg + 5 mg vial in 2 mL) describes the liquid. The per-component figure (2.5 mg/mL each) is what converts a target for one peptide into units. The calculator above reports both so you can check either.

What if the components are not in equal amounts?

The ratio still holds, it is just not 1:1. A vial with 10 mg BPC-157 and 5 mg TB-500 delivers twice as much BPC-157 as TB-500 in every draw. Enter the real milligrams of each component and the table shows what one draw contains of each.

How much bacteriostatic water should a blend vial get?

There is no single right amount — more water spreads a dose over more units, which is easier to read; less water keeps the injection volume down. The vial contains the same peptides either way. Decide it with your prescriber or pharmacist.

Peptide blend dosage calculator

For vials that hold more than one peptide — BPC-157 + TB-500, GLOW, KLOW. Enter each component and see what a single draw actually delivers of every one of them.

Verify every dose with your prescriber or pharmacist.

This is an educational arithmetic tool. It does not know your prescription or your product, it does not recommend a dose, and it is not medical advice.

A blend vial holds two or more peptides in one volume, so their ratio is fixed and one draw delivers all of them. A 5 mg BPC-157 plus 5 mg TB-500 vial mixed with 2 mL is 2.5 mg/mL of each, so 10 units on a U-100 syringe carries 250 mcg of both.

Everything in this vial shares one volume, so the ratio between the components is fixed. Drawing to a target for one of them decides the amount of all the others — they cannot be dosed independently without separate vials.

This converts a dose your prescriber has already set. It does not know your product or its actual content, it does not recommend a dose, and it is not medical advice.

The one thing blends get wrong

A blend is not two vials in a trench coat. Both peptides are lyophilised together and dissolve into the same liquid, so every microlitre you draw contains both in whatever ratio the vial was filled at. You can decide how much of the mixture to inject. You cannot decide how much of each component that mixture contains — that was fixed before you opened it.

This is why a units figure copied from someone else’s blend is close to meaningless. Their vial may have been 5 + 5 mg where yours is 10 + 5, or mixed with 3 mL where you used 2. The arithmetic below is the same in every case; only the inputs change.

Worked table: a 5 mg + 5 mg blend

Computed for a vial holding 5 mg of BPC-157 and 5 mg of TB-500 on a U-100 syringe. Each cell is what one draw carries of each component — the total peptide in the draw is twice that figure.

Units drawn	1 mL water	2 mL water	3 mL water
10 units	500 mcg each	250 mcg each	167 mcg each
20 units	1000 mcg each	500 mcg each	333 mcg each
30 units	1500 mcg each	750 mcg each	500 mcg each
50 units	2500 mcg each	1250 mcg each	833 mcg each

The figures are computed from the same code the calculator runs, so the table cannot drift away from the tool above it. They are example amounts, not a recommendation.

How to use a blended vial

Read the blend label. Note the milligrams of each component separately, not just the combined total. A "10 mg blend" can be 5 + 5, 7 + 3, or anything else.
Enter each component. Add one row per peptide with its own milligrams. The calculator derives each component concentration from the water you add.
Add the bacteriostatic water. Run it down the inside wall of the vial rather than onto the powder, then swirl until clear. Do not shake.
Anchor the target on one component. Choose the peptide your prescribed amount refers to, or the whole blend, and enter that amount. Everything else follows from the fixed ratio.
Check what the draw carries. Read the per-component table before drawing. It shows the mcg of every peptide in that one draw, including the ones you did not anchor on.
