Per-compound reconstitution
Each compound is calculated on its own — different vials, different concentrations, different draws. Use these references, then run your exact numbers on each compound's calculator.
BPC-157 reference
U100 units to draw for each common BPC-157 dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 200 mcg | 250 mcg | 500 mcg |
|---|---|---|---|---|
| 5 mg | 2.5 mg/mL | 8 u(0.08 mL) | 10 u(0.1 mL) | 20 u(0.2 mL) |
| 10 mg | 5 mg/mL | 4 u(0.04 mL) | 5 u(0.05 mL) | 10 u(0.1 mL) |
Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
TB-500 reference
U100 units to draw for each common TB-500 dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 2 mg | 2.5 mg | 5 mg |
|---|---|---|---|---|
| 2 mg | 1 mg/mL | 200 u(2 mL) | 250 u(2.5 mL) | 500 u(5 mL) |
| 5 mg | 2.5 mg/mL | 80 u(0.8 mL) | 100 u(1 mL) | 200 u(2 mL) |
| 10 mg | 5 mg/mL | 40 u(0.4 mL) | 50 u(0.5 mL) | 100 u(1 mL) |
Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
How the two schedules overlap
BPC-157 is short-acting and usually run on a daily or twice-daily schedule, while TB-500 is long-acting and often run as a higher weekly loading amount for the first few weeks, then a lower weekly maintenance amount. Because their cadences differ, you calculate and draw each one on its own — never mix them in a single syringe based on a combined number.
A typical overlapping block runs both compounds for 4–6 weeks: BPC-157 daily, TB-500 once or twice weekly. Tracking two reconstitution dates and two doses-remaining counts at once is exactly the kind of thing that gets miscounted on paper.
- Calculate BPC-157 and TB-500 separately — different vials, different concentrations
- BPC-157: daily/EOD; TB-500: weekly loading then weekly maintenance
- Keep two beyond-use dates and two doses-remaining counts in view
Why you never combine the math
It is tempting to add the two vial amounts together and draw once, but that produces the wrong dose for both compounds. Each vial is reconstituted to its own concentration, so the mL that delivers your TB-500 dose will deliver the wrong amount of BPC-157 and vice versa. The reference tables above show each compound's units independently; that is the correct way to run the stack.
- Two vials = two concentrations = two separate draws
- Combining the totals over-doses one compound and under-doses the other
- If a single blended vial is genuinely co-lyophilised, calculate from its labelled total instead
