BPC-157 + TB-500 Blend Dosage Calculator
Your blend
Both peptides are reconstituted together in one vial, so one draw covers both. The volume is worked out from the BPC-157 dose; if the two vial sizes differ, the TB-500 amount in that draw is shown in the result.
Estimate only, not medical advice. Peptides are research compounds; dosing must come from a licensed clinician.
Example: 5 mg of BPC-157 and 5 mg of TB-500 in 2 mL of water is 2,500 mcg/mL of each, so a 250 mcg dose of each is 0.10 mL — 10 units on an insulin syringe — with 20 doses per vial.
Behind the numbers
How a BPC-157 + TB-500 blend is calculated
In a blend, both peptide powders go into the same vial and share the same water, so each peptide has its own concentration based on its own amount. When the two amounts are equal — the usual 5 mg and 5 mg — the concentrations match, and one drawn volume delivers the same micrograms of each. Divide the dose per peptide by the BPC-157 concentration to get the volume in mL, then multiply by 100 for insulin syringe units.
5 mg × 1,000 ÷ 2 mL = 2,500 mcg/mL for each peptide. Then 250 mcg ÷ 2,500 mcg/mL = 0.10 mL, and 0.10 mL × 100 = 10 units.
A few comparisons
Example doses
| Vial | Water | Dose | Concentration | Volume | Units | Doses per vial |
|---|---|---|---|---|---|---|
| 5 mg + 5 mg | 2 mL | 250 mcg each | 2,500 mcg/mL each | 0.10 mL | 10 | 20 |
| 5 mg + 5 mg | 2 mL | 500 mcg each | 2,500 mcg/mL each | 0.20 mL | 20 | 10 |
| 5 mg + 5 mg | 3 mL | 250 mcg each | 1,667 mcg/mL each | 0.15 mL | 15 | 20 |
| 10 mg + 10 mg | 2 mL | 250 mcg each | 5,000 mcg/mL each | 0.05 mL | 5 | 40 |
| 5 mg BPC-157 + 10 mg TB-500 | 2 mL | 250 mcg BPC-157 | 2,500 / 5,000 mcg/mL | 0.10 mL | 10 | 20 |
Measure twice, draw once.
Keep the two amounts equal unless a clinician tells you otherwise — equal vials mean equal concentrations, so one volume always gives the same dose of each peptide.
More water means a lower concentration and a larger draw for the same dose, which can make small doses easier to measure accurately.
On an insulin syringe, 100 units = 1 mL. A 0.10 mL dose is 10 units; mixing up units and millilitres is the most common measuring mistake.
Keep the reconstituted vial refrigerated and follow your supplier’s storage guidance, and never use a dose worked out here without a licensed clinician’s direction.
Good to know
Your dosage questions, answered.
Why combine BPC-157 and TB-500?
They are commonly stacked because they are studied for different aspects of recovery, but that is a research topic, not a recommendation. This calculator only does the blend math for two vials reconstituted together in one vial.
How does the blend math work?
Each peptide gets its own concentration: amount in mg × 1,000 ÷ water in mL. With 5 mg of each in 2 mL, both are 2,500 mcg/mL, so a 250 mcg dose of each is 250 ÷ 2,500 = 0.10 mL — 10 units on an insulin syringe.
What if my vials are different sizes?
Type each amount into its own field. The volume is worked out from the BPC-157 dose, and the result shows the exact TB-500 amount in that same draw, plus the doses per vial limited by whichever peptide runs out first.
