BPC-157 Dosage Calculator (mcg & mL)

Getting the right dose from your BPC-157 vial doesn't have to involve confusing math. A BPC-157 dosing calculator takes three simple inputs) vial size, water volume, and desired dose (and tells you exactly how much to draw. No more second-guessing your syringe markings. No more wasted peptide from measurement errors.

Whether your provider prescribed 250 mcg or 500 mcg, knowing the exact draw volume matters. Too little and you may not get the full benefit. Too much and you run through your vial faster than planned. This guide breaks down the math behind the calculator and gives you quick-reference tables for the most common setups.

How the BPC-157 Dosing Math Works

The formula behind every dosing calculator is simple. Once you understand it, the numbers make sense.

The formula:

Draw Volume (mL) = Desired Dose (mcg) / Concentration (mcg per mL)

And concentration is:

Concentration (mcg/mL) = Total Peptide in Vial (mcg) / Volume of Water Added (mL)

"Compounding pharmacies serve a critical role in healthcare, but patients need to understand the difference between a properly regulated 503B facility and an unregulated operation. Ask about PCAB accreditation and third-party testing.") Dr. Scott Brunner, PharmD, Alliance for Pharmacy Compounding

Let us walk through the most common example. You have a 5 mg vial of BPC-157. That equals 5000 mcg. You add 2 mL of bacteriostatic water. Your concentration is 5000 / 2 = 2500 mcg per mL.

If your prescribed dose is 250 mcg, divide 250 by 2500. That gives you 0.1 mL. On a standard 1 mL insulin syringe with 100 unit markings, 0.1 mL equals 10 units.

It's that straightforward. But when you're dealing with different vial sizes or water volumes, the numbers shift. That's where a calculator saves time and prevents errors.

Patient Perspective: "I tried BPC-157 for a chronic rotator cuff issue after 8 months of physical therapy with minimal improvement. Within 3 weeks of a BPC-157 protocol alongside continued PT, I noticed significantly less pain during overhead movements. I can't say for certain what caused the improvement, but the timeline was notable.", Chris D., 38, FormBlends patient (name changed for privacy)

5 mg vial (5000 mcg) with 2 mL BAC water = 2500 mcg/mL

Desired Dose	Draw Volume	Syringe Units	Doses Per Vial
250 mcg	0.10 mL	10 units	20 doses
500 mcg	0.20 mL	20 units	10 doses

5 mg vial (5000 mcg) with 1 mL BAC water = 5000 mcg/mL

Desired Dose	Draw Volume	Syringe Units	Doses Per Vial
250 mcg	0.05 mL	5 units	20 doses
500 mcg	0.10 mL	10 units	10 doses

10 mg vial (10000 mcg) with 2 mL BAC water = 5000 mcg/mL

Desired Dose	Draw Volume	Syringe Units	Doses Per Vial
250 mcg	0.05 mL	5 units	40 doses
500 mcg	0.10 mL	10 units	20 doses

Using less water creates a more concentrated solution. This means smaller injection volumes, which some people prefer. Using more water makes it easier to measure smaller doses accurately. Your provider can recommend the best setup for your protocol.

How Many Days Does a Vial Last?

This depends on your dose and how many times per day you inject. Here is a quick breakdown for the most common protocol.

Standard protocol: 250 mcg twice daily (500 mcg total per day)

• 5 mg vial: 10 days
• 10 mg vial: 20 days

Higher-dose protocol: 500 mcg twice daily (1000 mcg total per day)

• 5 mg vial: 5 days
• 10 mg vial: 10 days

Knowing how long your vial lasts helps you plan ahead. If you're running a 4-week protocol at 250 mcg twice daily, you need about three 5 mg vials. Planning this in advance ensures you don't run out mid-cycle.

For help managing your protocol timeline, the lets you log each dose and track how many days remain in your current vial. It takes the guesswork out of reordering.

Frequently Asked Questions

What if I add the wrong amount of water to my vial?

If you add more water than planned, your concentration is lower. You'll need to draw a larger volume for the same dose. Use the formula above or the to recalculate based on your actual water volume. The peptide is still usable.

Can I use a different syringe size?

Yes. Most people use a 1 mL (100 unit) insulin syringe for subcutaneous BPC-157 injections. Some people prefer 0.5 mL (50 unit) syringes for more precise measurement of smaller volumes. The key is matching your draw volume to the syringe markings.

How do I know my prescribed dose is correct?

Your licensed provider determines your dose based on your health goals, weight, and the condition being treated. Common BPC-157 doses range from 250 to 500 mcg once or twice daily. Never adjust your dose without talking to your provider first.

What happens if I accidentally draw too much?

If you draw slightly more than intended, the difference is usually small and well within safe ranges. But try to be as accurate as possible. Good lighting, steady hands, and the right syringe size all help. If you consistently have trouble measuring, ask your provider about switching to a more concentrated reconstitution ratio that requires larger, easier-to-read draw volumes.
