BPC-157 + TB-500 Blend Dosage Calculator
Blended vials are where most dosing mistakes happen. A vial labeled '10 mg blend' usually contains 5 mg of each peptide — so calculate against the per-peptide amount, not the label total. Use the calculator with one peptide's mg at a time.
This is a unit converter. It converts an amount you already have into volume and syringe units. It does not tell you what to take, and it is educational only — not medical advice. Confirm every amount with your clinician and your product label.

What each vial size becomes at common bacteriostatic water volumes.
| Vial | + 1 mL | + 2 mL | + 3 mL | + 5 mL |
|---|---|---|---|---|
| 5 mg | 5.00 mg/mL | 2.50 mg/mL | 1.67 mg/mL | 1.00 mg/mL |
| 10 mg | 10.00 mg/mL | 5.00 mg/mL | 3.33 mg/mL | 2.00 mg/mL |
| 20 mg | 20.00 mg/mL | 10.00 mg/mL | 6.67 mg/mL | 4.00 mg/mL |
BPC-157 / TB-500 blend dosing evidence
No established, regulator-approved human dosing range. DoseRoutine performs arithmetic; it does not choose or recommend a dose. Your prescriber decides yours.
No single dosing table is shown because an established human range is unavailable or depends on the exact approved indication and product label.

What trips people up
- Read the label carefully: '10 mg blend' almost always means 5 mg + 5 mg, not 10 mg of each.
- One draw delivers both peptides in a fixed ratio — you cannot dose them independently from a blended vial.
- Because the two have very different half-lives, separate vials give better control if you care about protocol precision.
- Neither peptide has completed human efficacy trials. All frequency conventions come from user practice.
How the math works
- Concentration (mg/mL) = vial mg ÷ bacteriostatic water mL.
- Volume per dose (mL) = dose mg ÷ concentration.
- Syringe units = volume × 100 on a U-100 syringe, or × 40 on a U-40 syringe.
- Doses per vial = vial mg ÷ dose mg. Water volume never changes this number.
BPC-157 / TB-500 blend calculator FAQ
How do I calculate a BPC-157 / TB-500 blend dose?
Split the vial into its two peptide amounts first. For a 10 mg blend that is 5 mg BPC-157 and 5 mg TB-500. Then run the reconstitution math on one peptide's mg — the syringe units are the same for both because they share the same liquid volume.
Is a blend better than separate vials?
Convenience yes, control no. BPC-157 suits daily dosing and TB-500 suits twice-weekly dosing, and a blend forces one schedule on both. Separate vials cost more effort and give a cleaner protocol.
How much BAC water for a 10 mg BPC-157 / TB-500 blend?
3–5 mL. More water gives larger, easier-to-read draws. At 10 mg total in 5 mL you have 1 mg/mL of each peptide, so 25 units delivers 250 mcg BPC-157 alongside 250 mcg TB-500.
Can I inject a blend every day?
People do, but it means the TB-500 side is dosed far more often than its long half-life requires. If you plan to dose daily, separate vials let you keep TB-500 on a twice-weekly schedule.
