BPC-157 Dosage Calculator
A 5 mg BPC-157 vial mixed with 2 mL of bacteriostatic water gives 2.5 mg/mL, so 250 mcg is 0.10 mL — 10 units on a U-100 insulin syringe.

BPC-157 is not an FDA-approved drug, and no human dose has been established. An FDA advisory committee voted in July 2026 to recommend it for the pharmacy-compounding list, but the FDA has not made a final decision. It is also prohibited in sport (WADA class S0). This page performs arithmetic on numbers you enter — it does not suggest, endorse or validate any dose. Discuss any use with a licensed clinician.

How Many Units Is 250 mcg of BPC-157?
In a 5 mg BPC-157 vial mixed with 2 mL of bacteriostatic water, 250 mcg is 10 units on a U-100 insulin syringe (0.10 mL). In a 10 mg vial with 2 mL it is 5 units, and in a 2 mg vial with 2 mL it is 25 units. The number of units always depends on how much water was added, so check your own vial in the calculator above.
How many units is 200 mcg of BPC-157?
8 units (0.08 mL) in a 5 mg vial with 2 mL of water. In a 10 mg vial it is 4 units with 2 mL, or 6 units with 3 mL.
How many units is 300 mcg of BPC-157?
12 units (0.12 mL) in a 5 mg vial with 2 mL of water. In a 10 mg vial it is 6 units with 2 mL, or 9 units with 3 mL.
How many units is 500 mcg of BPC-157?
20 units (0.20 mL) in a 5 mg vial with 2 mL of water. In a 10 mg vial it is 10 units with 2 mL, or 15 units with 3 mL; in a 2 mg vial with 2 mL it is 50 units.
How many mcg is 10 units of BPC-157?
250 mcg in a 5 mg vial with 2 mL of water. The same 10 units hold 500 mcg in a 10 mg vial with 2 mL, and about 333 mcg in a 10 mg vial with 3 mL.
The reason is simple arithmetic: 5 mg dissolved in 2 mL gives 2,500 mcg in every millilitre. A U-100 syringe divides one millilitre into 100 units, so each unit holds 25 mcg. Ten units therefore deliver 250 mcg. Change the water and every number shifts with it — which is why a “units” figure copied from a forum is meaningless unless you know the vial and water it came from.
BPC-157 Dosage Chart
Amounts most often cited in online protocols range from 200–500 mcg once or twice daily over 4–6 weeks. These come from community convention extrapolated from animal studies, not from human trials. The chart below shows what each amount looks like in syringe units. It is reporting, not a recommendation — the amount you use should come from a licensed clinician.
| Amount per injection | 5 mg vial + 2 mL | 10 mg vial + 2 mL | 10 mg vial + 3 mL |
|---|---|---|---|
| 100 mcg | 4 units (0.04 mL) | 2 units (0.02 mL) | 3 units (0.03 mL) |
| 200 mcg | 8 units (0.08 mL) | 4 units (0.04 mL) | 6 units (0.06 mL) |
| 250 mcg | 10 units (0.1 mL) | 5 units (0.05 mL) | 7.5 units (0.075 mL) |
| 300 mcg | 12 units (0.12 mL) | 6 units (0.06 mL) | 9 units (0.09 mL) |
| 400 mcg | 16 units (0.16 mL) | 8 units (0.08 mL) | 12 units (0.12 mL) |
| 500 mcg | 20 units (0.2 mL) | 10 units (0.1 mL) | 15 units (0.15 mL) |
Units on a U-100 insulin syringe (100 units = 1 mL). Concentrations: 5 mg + 2 mL = 2,500 mcg/mL (25 mcg per unit); 10 mg + 2 mL = 5,000 mcg/mL (50 mcg per unit); 10 mg + 3 mL ≈ 3,333 mcg/mL (about 33 mcg per unit). Twice-daily use doubles the vial consumption shown in the doses-per-vial table below.

| Vial + BAC water | Concentration | mcg per unit | 100 mcg | 250 mcg | 500 mcg |
|---|---|---|---|---|---|
| 2 mg + 1 mL | 2 mg/mL | 20 | 5 u | 12.5 u | 25 u |
| 2 mg + 2 mL | 1 mg/mL | 10 | 10 u | 25 u | 50 u |
| 5 mg + 1 mL | 5 mg/mL | 50 | 2 u | 5 u | 10 u |
| 5 mg + 2 mL | 2.5 mg/mL | 25 | 4 u | 10 u | 20 u |
| 5 mg + 2.5 mL | 2 mg/mL | 20 | 5 u | 12.5 u | 25 u |
| 5 mg + 3 mL | 1.67 mg/mL | 16.7 | 6 u | 15 u | 30 u |
| 10 mg + 1 mL | 10 mg/mL | 100 | 1 u | 2.5 u | 5 u |
| 10 mg + 2 mL | 5 mg/mL | 50 | 2 u | 5 u | 10 u |
| 10 mg + 3 mL | 3.33 mg/mL | 33.3 | 3 u | 7.5 u | 15 u |
| 20 mg + 2 mL | 10 mg/mL | 100 | 1 u | 2.5 u | 5 u |
| 20 mg + 3 mL | 6.67 mg/mL | 66.7 | 1.5 u | 3.75 u | 7.5 u |
“u” = units on a U-100 insulin syringe (100 units = 1 mL). Readings below about 5 units are hard to measure precisely on a 1 mL syringe.
How many doses are in a BPC-157 vial — and do they expire first?
The vial’s total micrograms divided by the amount per injection gives the number of doses. The column on the right is the one most calculators skip: a reconstituted multiple-dose vial is generally discarded 28 days after first puncture.
| Vial size | Doses at 100 mcg | Doses at 250 mcg | Doses at 500 mcg | Once daily at 250 mcg |
|---|---|---|---|---|
| 2 mg (2,000 mcg) | 20 | 8 | 4 | Used in 8 days |
| 5 mg (5,000 mcg) | 50 | 20 | 10 | Used in 20 days |
| 10 mg (10,000 mcg) | 100 | 40 | 20 | 12 doses past day 28 |
| 20 mg (20,000 mcg) | 200 | 80 | 40 | 52 doses past day 28 |
How the BPC-157 Reconstitution Math Works
Concentration (mcg/mL) = vial mg × 1,000 ÷ water mL
Volume (mL) = amount mcg ÷ concentration
Units = volume × 100 (U-100) or × 40 (U-40)
mcg per unit = concentration ÷ 100 (U-100)
Worked example (the calculator’s default)
- 5 mg vial + 2 mL water → 5 × 1,000 ÷ 2 = 2,500 mcg/mL
- 250 mcg ÷ 2,500 = 0.10 mL → × 100 = 10 units
- 5,000 ÷ 250 = 20 doses, used within the 28-day window at once daily
Mixing it with TB-500 (the “Wolverine” blend)
Many vials sold online combine BPC-157 and TB-500. In a 5 mg + 5 mg vial, both peptides are at the same concentration, so every unit carries equal micrograms of each. In a 10 mg + 5 mg vial, each injection contains half as much TB-500 as BPC-157. Blend mode shows this split automatically. If you dose by the TB-500 amount instead, use the TB-500 Dosage Calculator.
Why This Page Has No “BPC-157 Dosage by Body Weight” Calculator
Some sites ask for your weight and a goal, then output a daily microgram figure. I deliberately did not build that, and here is the reasoning.
The mcg/kg numbers come from rats
The best-known tendon and ligament studies gave rats intraperitoneal BPC-157 at 10 mcg/kg, 10 ng/kg or even 10 pg/kg — a millionfold spread that all produced reported effects. That pattern does not describe a human dose.
Scaling isn’t a dosing method
FDA’s body-surface-area conversion exists to choose a cautious starting dose for a first-in-human safety trial, with a safety factor applied on top. It was never meant to turn an animal result into a treatment dose.
The goal presets aren’t evidence-based
No controlled human trial has compared amounts for “injury”, “gut” or “wellness”. A tool that implies otherwise turns guesswork into false precision, which is the opposite of what a calculator should do.
What Human Research on BPC-157 Actually Exists
BPC-157 (Body Protection Compound-157) is a synthetic 15-amino-acid peptide based on a fragment of a protein found in gastric juice. Most of its research is in animals. When the FDA reviewed it in July 2026, the agency’s briefing identified only a handful of human reports.
| Research | Design | What it can and can’t tell you |
|---|---|---|
| Ulcerative colitis enema studies (PL 14736), early 2000s | Placebo-controlled; published as meeting abstracts | Never developed into a full published trial or an approved product. |
| Knee pain pilot, 2021 | Small, uncontrolled, retrospective | No placebo group, so improvement can’t be attributed to BPC-157. |
| Interstitial cystitis pilot, 2024 | Small, uncontrolled | Hypothesis-generating only. |
| IV safety pilot (Lee & Burgess, 2025) | 2 healthy adults, 10 mg then 20 mg by infusion | A tolerability check in two people — not an efficacy or dose-finding study. |
| Animal pharmacokinetics (He et al., 2022) | Rats and dogs | Half-life under 30 minutes in these animals; human pharmacokinetics are not established. |
Where the “250 mcg” figure comes from
Almost every BPC-157 calculator, including this one, uses 250 mcg as its example input. That number comes from online community convention, not from a human dose-finding trial. I keep it as the default only so the tool shows a realistic worked example — please don’t read it as a recommendation.
Is BPC-157 Legal? FDA Status in 2026
BPC-157 is not FDA-approved, and no approved BPC-157 drug exists. The question most people actually mean is whether a licensed pharmacy may compound it with a prescription — and that answer has been moving all year.
- 2023
FDA places BPC-157 in Category 2 — bulk substances that raise significant safety concerns — effectively blocking routine compounding.
- February 27, 2026
HHS announces that most peptides on the Category 2 list will be moved back for review.
- April 2026
BPC-157 is removed from Category 2 after its nominations were withdrawn. Removal alone does not make it eligible for compounding.
- July 23, 2026
The FDA’s Pharmacy Compounding Advisory Committee votes 8–6 (one abstention) to recommend BPC-157 for the 503A bulks list for ulcerative colitis, against FDA staff’s recommendation. Staff described the peptide as not well characterized and cited a lack of efficacy evidence.
- As of October 23, 2026
We found no final FDA rule. A committee vote is advisory; any listing would still need proposed rulemaking, public comment and a final decision.
Sport and military
BPC-157 is named in WADA’s S0 class (non-approved substances) and is prohibited at all times, in and out of competition. Athletes subject to testing should treat it as banned.
“Research use only” vials
Products labelled for research are not made or tested to pharmaceutical standards and are not intended for human use. Their real content, sterility and purity are unverified — the reason for the label-accuracy check in the calculator.
BPC-157 Safety, Storage and Reconstitution Basics
What is known about safety
- FDA’s July 2026 briefing noted three adverse-event reports after injection, including several days of redness and swelling at the injection site; whether BPC-157 caused them is unclear.
- BPC-157 influences blood-vessel growth (angiogenesis) in animal studies. Some experts have raised a theoretical concern for people with a current or past cancer; there are no human data to settle it.
- There are no data in pregnancy or breastfeeding, and drug interactions have not been studied.
- Contaminated or non-sterile products can cause infection regardless of the peptide itself.
Reconstitution and storage
- Bacteriostatic water (0.9% benzyl alcohol) allows a vial to be entered repeatedly; sterile water has no preservative and is meant for single use.
- Run the water slowly down the inside of the vial, then swirl gently — never shake.
- Keep the reconstituted vial refrigerated at 2–8 °C, protected from light. Do not freeze it.
- Under USP <797>, a preserved multiple-dose vial generally carries a 28-day beyond-use date after first puncture.
Oral vs injectable BPC-157
BPC-157 is sold both as capsules and as freeze-dried powder for injection. Animal studies used several routes, including drinking water, and the peptide is described as unusually stable in gastric juice. Human data for either route are minimal. This calculator applies only to reconstituted vials.
BPC-157 vs TB-500
They are different molecules. BPC-157 is a gastric-protein fragment; TB-500 is a synthetic fragment related to thymosin beta-4. They are often sold together in one vial, which is why this page includes a blend mode. Neither is FDA-approved. For TB-500 on its own, see the TB-500 dosage calculator.
Questions to Ask Your Doctor or Pharmacist
- Is there an approved treatment for my condition that has stronger evidence?
- Where is this product made, and is there a batch-specific certificate of analysis from an independent lab?
- Do I have any history — including cancer — that makes a growth-related peptide a poor idea?
- How will we judge whether it’s working, and when should I stop?
- Which syringe should I use, and can you check my first syringe reading with me?
- Am I subject to sports or workplace drug testing?

In a 5 mg vial with 2 mL of bacteriostatic water, 250 mcg is 10 units on a U-100 syringe. In a 10 mg vial with 2 mL it is 5 units, and in a 2 mg vial with 2 mL it is 25 units.
In a 5 mg vial with 2 mL of bacteriostatic water, 200 mcg is 8 units (0.08 mL) on a U-100 syringe. In a 10 mg vial it is 4 units with 2 mL of water or 6 units with 3 mL.
In a 5 mg vial with 2 mL of water, 300 mcg is 12 units (0.12 mL). In a 10 mg vial it is 6 units with 2 mL or 9 units with 3 mL.
In a 5 mg vial with 2 mL of water, 500 mcg is 20 units (0.20 mL). In a 10 mg vial it is 10 units with 2 mL or 15 units with 3 mL, and in a 2 mg vial with 2 mL it is 50 units.
It depends on the mix: 250 mcg in a 5 mg vial with 2 mL of water, 500 mcg in a 10 mg vial with 2 mL, and about 333 mcg in a 10 mg vial with 3 mL.
2 mL is the most common choice; it gives 2.5 mg/mL, or 25 mcg per U-100 unit. The calculator’s optimizer shows which volumes put your prescribed amount on a clear syringe mark.
Adding 2 mL of bacteriostatic water gives 5 mg/mL (50 mcg per unit); adding 3 mL gives 3.33 mg/mL. Inject the water slowly down the vial wall, swirl gently and refrigerate. At small daily amounts a 10 mg vial may not be used up within 28 days.
Divide the amount in mcg by the concentration in mcg/mL. With 2,500 mcg/mL, 250 mcg equals 0.1 mL. Multiply by 100 to get U-100 syringe units.
There isn’t one. BPC-157 is not an approved drug and no controlled human trial has established a dose. Online protocols most often cite 200–500 mcg once or twice daily for 4–6 weeks, but those figures come from animal studies and community convention. This calculator converts an amount your clinician specifies; it does not recommend one.
Per-kilogram figures come from rat studies, and converting them to people isn’t a validated way to set a treatment dose. That’s why this page does not offer a weight-based calculator.
It is not FDA-approved. In July 2026 an FDA advisory committee voted 8–6 to recommend adding it to the 503A compounding list, but as of October 2026 the FDA had not issued a final rule. It is also prohibited by WADA at all times.
Stability data for unregulated vials are limited. A preserved multiple-dose vial is generally given a 28-day beyond-use date after first puncture under USP <797>. Keep it refrigerated and protected from light.
Use Blend mode. Enter the BPC-157 mg and the TB-500 mg in the vial; the units are set by your BPC-157 amount, and the table shows how much TB-500 comes with it in each injection.
The amount doesn’t change if you read the right scale, but the numbers do. A U-40 syringe has 40 units per mL, so a 0.1 mL draw reads 4 units, not 10. Always select the syringe you are holding.
Then every calculation is off by the same percentage. A vial with 80% of its labelled content delivers 200 mcg when you expect 250 mcg. The label-accuracy check shows this range for your own numbers.
