BPC-157 Dosage Protocol

Body Protection Compound-157 · pentadecapeptide

BPC-157 is taken once daily under the skin in the reference protocol: 200 mcg for weeks 1–2, 400 mcg for weeks 3–4, then 600 mcg. With 3 mL of bacteriostatic water, a 10 mg vial is 3.33 mg/mL — so 200 mcg is 6 units on a U-100 syringe.

02 · HOW TO MIX

Mixing a 10 mg vial with 3 mL of BAC water

Using a 1 mL (100-unit) insulin syringe, 3 full draws of bacteriostatic water gives 3.33 mg/mL.

1
Add the water slowly
Wipe both rubber stoppers with an alcohol swab and let them dry. Draw 3 mL of bacteriostatic water and let it run slowly down the inside of the vial wall — not straight onto the powder.
2
Swirl gently
Swirl or roll the vial gently until the powder has dissolved. Give it a few minutes to settle if needed.
3
Don't shake it
Shaking can damage the peptide and cause foaming. Gentle swirling only.
4
Check it's fully clear
Only use it once it is fully clear with no particles. Label the vial with the date and 3.33 mg/mL, then store it in the fridge at 2–8 °C.

About BPC-157

Protocol overview

Starting dose: 200 mcg once daily
How it increases: 400 mcg in weeks 3–4, then 600 mcg from week 5
Frequency: Once daily
When to take it: Any consistent time of day
Cycle length: 8–12 weeks (up to 16)
Common mix: 3 mL BAC water → 3.33 mg/mL

Storage

Before mixing: Freezer (−20 °C), sealed and away from light.
After mixing: Fridge at 2–8 °C, protected from light. Follow the use-by period on the product label.
Never: Freeze and thaw it repeatedly, or use it if it is cloudy or has particles.

How it works

BPC-157 is a synthetic 15-amino-acid peptide based on a sequence from a protein found in stomach juice — the name stands for Body Protection Compound.

In animal studies it encouraged new blood-vessel growth, interacted with the nitric-oxide system and sped up tendon, ligament and muscle healing. None of these effects has been confirmed in human trials.

Illustrated mechanism explainer

What the research shows

A 2025 systematic review in orthopaedics found 36 studies: 35 were in animals and only one was a small human report.
A 2025 intravenous pilot gave 10 mg and 20 mg infusions to two adults with no measured side effects or blood-marker changes — far too small to show safety.
In rats and dogs, BPC-157 lasted less than 30 minutes in the blood (half-life).
A phase 1 oral safety study was registered (NCT02637284). US FDA reviewers found there is not enough human safety information, and BPC-157 is not an approved medicine in Australia.

Reported side effects

Human safety data are very limited.
Reports mainly describe redness or irritation where it was injected.
FDA reviewers flagged unknown risks of immune reactions and impurities in unregulated products.

Important notes

Not approved for human use in Australia — it is sold as a research product.
Prohibited in sport: WADA lists BPC-157 as a non-approved substance (S0).
There is no reliable human dosing data; the amounts above are community-reported.
Never use a mixed vial that is cloudy or has particles in it.

Injection basics

Use a new sterile 1 mL (100-unit) U-100 insulin syringe, 27–31G, every time — never reuse or share.
Wipe the vial stopper and the skin with an alcohol swab and let both dry first.
Inject under the skin (subcutaneously) of the abdomen, thigh or upper arm, and rotate sites.
Put used syringes straight into an approved sharps container — the NDSS lists Australian disposal options.
