For total-vial duration, use the total powder in the vial. If a label says 5 mg + 5 mg, that is 10 mg total. For per-component math, you need to know how much of each component is in the blend and whether the blend is evenly distributed.
Total blend math
A blend labeled 5 mg BPC-157 + 5 mg TB-500 contains 10 mg total powder. If the intended dose is a total blend dose, use 10 mg as the vial size.
Per-component math
If you are trying to know how much BPC-157 or TB-500 is in each draw, use each component's amount and the same BAC water volume. That gives per-component concentration.
Blend caution
- Blends are convenient but less adjustable.
- Singles give cleaner per-compound control.
- If a label is vague, do not guess what is in each dose.
