BPC-157 / TB-500 Blend Dosing Calculator & Reconstitution Guide

A common approach is to add 3 mL of bacteriostatic water to a 10 mg vial, which gives 3.333 mg/mL. Add the water slowly down the vial wall, swirl gently rather than shaking, and let the powder dissolve fully before drawing.

At 3.333 mg/mL, 500 mcg equals 0.15 mL, which is 15 units on a U-100 insulin syringe.

Community and anecdotal reports commonly cite 500 to 750 mcg. These are figures people report, not a recommendation from Keel. This blend combines BPC-157 and TB-500, two peptides frequently studied together for tissue repair and recovery. The combined dose is typically expressed in total micrograms drawn per injection.

A U-100 insulin syringe is standard. A 0.3 mL (30-unit) syringe gives the most precise measurement for small draws, while a 0.5 mL or 1 mL syringe is better when the draw exceeds 30 units. Keel warns you when a dose is larger than the syringe you select.

Divide your dose in micrograms by the concentration in micrograms per millilitre to get the volume in millilitres, then multiply by 100 for units on a U-100 syringe. The Keel calculator does this for you and shows the draw on a to-scale syringe.

Reconstituted peptides are generally kept refrigerated and protected from light, with the unmixed powder stored cooler still. Follow the guidance from your supplier or a licensed healthcare professional for the specific compound.

Either use a larger insulin syringe or reconstitute with more bacteriostatic water to lower the concentration, which increases the volume per dose so it fits. Keel flags an over-draw and you can adjust the inputs until the draw fits.

No. The right draw depends on your vial size, how much bacteriostatic water you add, and your target dose. Always recalculate when any of those change, and consult a licensed healthcare professional.
