BPC-157 / TB-500 Blend Calculator
BPC-157 / TB-500 is a community label rather than a standard formulation. This calculator starts with separate label masses for BPC-157, TB-500 and divides each by one measured diluent volume. It reports each component's concentration and mass per U-100 unit. It states no dose and does not endorse a blend.

How the component table is calculated
For each component, concentration equals its labelled milligrams multiplied by 1,000 and divided by the measured millilitres of diluent. Mass per U-100 unit equals that concentration divided by 100. The calculator keeps each component separate so a combined vial is not mistaken for one undifferentiated mass.
| Component | Editable label example | Shared input |
|---|---|---|
| BPC-157 | 10 mg | Measured diluent volume |
| TB-500 | 10 mg | Measured diluent volume |
What a community blend name does not prove
Names such as BPC-157 / TB-500 are used inconsistently. Two vials carrying the same nickname may list different components or masses. Record the exact printed composition rather than relying on the nickname, and treat the calculator defaults only as editable examples.
Two component names, two different identity problems
The BPC-157 reference is a defined free-base peptide record, while TB-500 is not a sufficiently precise chemical identifier without a sequence or certificate qualifier. A combined label should therefore preserve each component's exact chemical form separately. The calculator can divide both printed masses by one shared volume, but it cannot prove that the TB-500 material is full-length thymosin beta-4 or that the BPC-157 material matches the linked free-base record.

Frequently asked questions
Does this BPC-157 / TB-500 calculator recommend an amount?
No. It divides each label mass by one measured volume and shows the result per millilitre and per U-100 unit. Every mass originates in an editable field.
Why are blend components calculated separately?
A syringe volume contains a proportional amount of every listed component. Separate rows preserve that composition instead of presenting only the total mass.
Are the default component masses a standard formula?
No. Community blend names are not standardised. The defaults are arithmetic examples and must be replaced with the exact masses printed on the label being recorded.
Does the website store the values entered?
No. The calculation runs in the browser and the website does not transmit or save the values entered into the form.
