BPC-157 + TB-500 Blend Dosage Calculator
A free dosage calculator for a combined BPC-157 and TB-500 vial. Enter each peptide amount and one water volume to get the single draw and how much of each compound it delivers.
Important: This calculator does not decide what dose to use. It converts amounts you already have into a concentration and a draw volume. BPC-157 and TB-500 are research compounds that are not approved for human use. Independently verify every calculation and confirm your product details before relying on any result.

How to Use the Blend Calculator
A blended vial is the one case where a single-compound calculator falls short, because two peptides share one liquid. Enter the BPC-157 amount, the TB-500 amount, and the single water volume you added to the vial. Set a target dose for one of the two compounds and choose which one it applies to.
The calculator returns the single draw that hits that target, the units to draw on a U-100 insulin syringe, and, in the same panel, how much of the other peptide that identical draw delivers. That last figure is the question a blend creates and a normal calculator cannot answer. Change any value and everything updates instantly.
How This Calculator Works
The calculator runs the math for both compounds off one shared water volume, and you can check each step.
Each compound's concentration = its amount ÷ the shared water. Draw volume = your target dose ÷ the target compound's concentration. The same draw then delivers each peptide in proportion to its own concentration.
Worked in arbitrary numbers: say a vial holds 10 mg BPC-157 and 5 mg TB-500 in 2 ml of water. BPC-157 sits at 5,000 mcg/ml and TB-500 at 2,500 mcg/ml in the same solution. Target 250 mcg of BPC-157, and the draw is 250 ÷ 5,000, which is 0.05 ml, or 5 units. That same 0.05 ml draw also delivers 125 mcg of TB-500, because both peptides come out of the vial together. The numbers here are example inputs to show the arithmetic, not a suggested dose.
Every figure appears in the result panel, so you can verify the split yourself rather than trusting one number.
Why a Blend Needs Its Own Calculator
The reason a blend is different comes down to one fact: you draw both compounds in the same pull, so you cannot set them independently. Once the two amounts and the water are fixed, the ratio between them is locked. Dosing one to a target automatically fixes the other, and the only levers you have are the two starting amounts and the water volume. That is why this tool asks which compound your target applies to, then reports the other as an output rather than an input. If the delivered amount of the second peptide is not where you want it, the fix is to change the amounts you put in the vial, not the draw. For the reconstitution math common to every peptide, see the main peptide calculator.
Setting Your Blend Ratio
The ratio is set at reconstitution, not at the syringe. If you want the two peptides to deliver in equal amounts per draw, put equal milligrams of each in the vial, since equal amounts in the same water give equal concentrations. If you want more of one than the other per injection, weight the vial that way from the start. A 10 mg BPC-157 with 5 mg TB-500 vial delivers BPC-157 and TB-500 in a two-to-one ratio in every draw, no matter how much you pull. The calculator makes this visible: change either amount and watch how the second compound's delivered dose moves while the first stays on your target.
What BPC-157 and TB-500 Are
BPC-157 is a synthetic 15-amino-acid peptide based on a protective sequence from gastric juice. TB-500 is a synthetic peptide based on the actin-binding fragment of thymosin beta-4. Both are studied in tissue-repair research, which is why they are sometimes combined in a single research vial. This page is the calculation tool for that combined vial. For each compound on its own, see

TB-500 healing peptide guide.

Wolverine protocol.
Reading Your Result Accurately
The calculator's accuracy depends on your inputs, and a blend adds one thing to confirm. First, enter both peptide amounts exactly as the vial is labeled, since the whole split depends on the ratio between them. Second, check the delivered dose of the non-target compound before you draw, because it is easy to focus on the compound you set and miss that the other is higher or lower than you intended. Third, watch the syringe fit: the draw is driven by whichever compound you dosed to, and a low concentration can push the volume past a small syringe, which the calculator flags. The result panel shows both delivered doses and the draw together, so you can confirm the whole picture in one place.
WHAT YOU NEED BEFORE YOU DRAW
This calculation gives you the exact volume to draw and the dose of each compound it delivers, but accuracy depends on the right supplies and correct reconstitution. Before measuring a dose, review
how to take a peptide shot for syringe setup and injection technique, and
how to reconstitute peptides for the mixing steps. To run the two compounds together as a recovery stack, see the
Wolverine protocol.

BPC-157 and TB-500 Blend Calculator FAQ
Is the blend calculator medical advice?
No. It is a math tool for research and educational use only. It converts amounts you enter into concentrations and syringe units. It does not recommend a dose, diagnose anything, or replace a qualified professional. Independently verify every calculation before relying on it.
How do I reconstitute a BPC-157 and TB-500 blend vial?
Add bacteriostatic water to the vial holding both peptides and let the powder dissolve without shaking. The single water volume sets both concentrations at once, so 10 mg BPC-157 and 5 mg TB-500 in 2 ml gives 5,000 and 2,500 mcg per ml in the same solution. Enter both amounts and the water volume, and the calculator shows the draw and each delivered dose.
If I dose one peptide, how do I know the other?
You do not set it, the calculator reports it. Because both compounds share one draw, fixing the dose of one fixes the volume, and that volume delivers the second compound in proportion to its own concentration. The result panel shows that second dose automatically.
How do I change the ratio of the two peptides?
Change the amounts you put in the vial, not the draw. The ratio between the two delivered doses is locked once the vial is mixed. More milligrams of one compound relative to the other at reconstitution means more of it per injection.
Why do blend calculators give different results?
Results differ when calculators assume different peptide amounts, water volumes, or syringe types, or when they round differently. This calculator shows both concentrations and the exact units so you can check the math against what you actually put in the vial. More on this in our note on why peptide calculators differ.
