BPC-157 TB-500 Blend Dosage Calculator
BPC-157 + TB-500 blend vials contain both peptides. One injection delivers both peptides at once. Calculate your dose below.
The BPC-157 + TB-500 blend combines two research peptides in one vial. In animal literature, BPC-157 is associated with localised angiogenesis-driven repair and TB-500 (Thymosin Beta-4) with systemic cell-migration effects. Combination use is a community practice, not a studied protocol: no published trial has evaluated this blend, and neither peptide is FDA-approved.
For a 5mg blend vial (BPC-157 + TB-500): add 2ml of bacteriostatic water → concentration is exactly 2500 mcg/ml. For a 250mcg BPC-157 component dose, inject 0.10ml (10 units) on a 100-unit syringe.
Dose Reference Table
Pre-calculated for a 5mg vial + 2ml BAC water = 2,500 mcg/ml concentration. Using a 100-unit (1ml) insulin syringe.
| Dose | Inject Volume (ml) | Syringe Units |
|---|---|---|
| 125mcg BPC / 500mcg TB | 0.050 ml | 5 units |
| 250mcg BPC / 1000mcg TB | 0.100 ml | 10 units |
| 500mcg BPC / 2000mcg TB | 0.200 ml | 20 units |
| 750mcg BPC / 3000mcg TB | 0.300 ml | 30 units |
| 1000mcg BPC / 4000mcg TB | 0.400 ml | 40 units |
About BPC-157 TB-500 Blend
BPC-157 + TB-500 blend vials are pre-made combinations containing both peptides in a single vial. This allows researchers to administer both compounds with a single injection, which is convenient compared to drawing from two separate vials.
The typical blend ratio is approximately 4:1 TB-500 to BPC-157 by mass. In a standard 5mg blend vial, this often means 4mg TB-500 + 1mg BPC-157, or an even split depending on the vendor. Always check the specific ratio listed on your vial.
Read the table correctly: the volumes below assume the BPC-157 component of your blend is at 2,500 mcg/ml (a 5mg BPC-157 equivalent in 2ml). At that concentration, 0.10ml delivers 250mcg of the BPC-157 component plus the proportional TB-500 amount at the blend's stated ratio — you draw one volume and get both peptides. If your vial's total peptide content differs, use the calculator above with your own numbers: a "5mg blend" vial whose content is 1mg BPC + 4mg TB gives 2,500 mcg/ml of total peptide, which is not 2,500 mcg/ml of BPC-157. Confirm your supplier's per-component amounts before drawing.
Reconstitution is the same as for any other peptide — 2ml of bacteriostatic water for a 5mg vial gives 2,500 mcg/ml total concentration. The individual peptide concentrations will depend on the split ratio in your specific blend.

How this calculator works
Every result comes from the same three formulas used for any lyophilized peptide: concentration (mcg/ml) = vial mg × 1,000 ÷ BAC water ml; injection volume (ml) = desired dose mcg ÷ concentration; syringe units = injection volume ml × 100 on a U-100 syringe.
For the preset BPC-157 TB-500 Blend setup on this page: a 5mg vial mixed with 2ml of bacteriostatic water gives a concentration of 2,500 mcg/ml. A 250mcg dose then needs 0.10ml, which is 10 units on a 100-unit insulin syringe.

Accuracy & limitations
The arithmetic itself is exact — the same inputs always produce the same output. Real-world accuracy depends on things outside the calculator: actual vial contents can vary slightly from the labeled amount within manufacturing tolerance, the BAC water volume should be measured carefully, and syringe readings are taken at the bottom edge of the plunger. Reconstituted peptides also degrade over time (the common guidance is to use within about 28 days refrigerated), which the math does not model. This tool does arithmetic only — it does not recommend doses, and it is not medical advice.
