Dosing & Reconstitution Guide
Two reconstitution strategies with accurate daily dosing, step by step
Standard / Gradual Approach (3 mL = ~1,667 mcg/mL)
Reconstitute: Add 3.0 mL bacteriostatic water to one 5 mg vial → final concentration: ~1,667 mcg/mL.
Typical daily range: 200–300 mcg once daily across a 4–8 week course.
Easy measuring: At ~1,667 mcg/mL, 200 mcg ≈ 12 units and 300 mcg ≈ 18 units on a U-100 insulin syringe.
Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and use within ~30 days.
Advanced / Aggressive Approach (2 mL = ~2,500 mcg/mL)
Reconstitute: Add 2.0 mL bacteriostatic water to one 5 mg vial → final concentration: ~2,500 mcg/mL.
Typical daily range: 250 mcg per injection, 2× daily for those referencing twice-daily BPC-157 schedules.
Easy measuring: At ~2,500 mcg/mL, 250 mcg ≈ 10 units per injection on a U-100 syringe.
Note: Each injection volume stays well within a single 100-unit insulin syringe.
Compact volumes: mixing to ~2,500 mcg/mL keeps each injection at ~10 units when dosing 250 mcg twice daily. Splitting the daily total across two injections is common in twice-daily reference schedules.
Why BPC-157 draws research interest
These are the directions researchers and the peptide community most often explore BPC-157 for — so you know you’re in the right place. They describe what is being studied, not proven benefits, approved uses, or promised results.
Tissue repair
The primary reason people look into BPC-157: studied preclinically for how it may influence soft-tissue healing in animal models.
Injury recovery
Investigated in animal research on recovery from tendon, ligament, and muscle soft-tissue injury; not an approved human therapy.
Gut & GI protection
Derived from a gastric-juice protein and explored in preclinical work on protection of the stomach and intestinal lining.
Anti-inflammatory
Researched in animal-only studies for its effects on inflammatory and vascular responses; remains investigational, not approved.
Evidence ranges from early laboratory work to clinical trials depending on the use — the sections below cover the actual data and sources.
Important: Read the Prep & Injection Guide first — it covers the preparation and safety basics that every protocol on this site assumes.
Frequency: one subcutaneous (or intramuscular) injection each day. A moderate 200–300 mcg daily dose is the most commonly referenced range for tissue-repair protocols[3]. These figures come from reference protocols, not from approved human dosing.
Reconstitution Steps
Draw the chosen volume of bacteriostatic water (3.0 mL for ~1,667 mcg/mL, or 2.0 mL for ~2,500 mcg/mL) into a sterile syringe.
Release it slowly against the vial’s inner wall to reduce foaming.
Swirl or roll gently until fully dissolved — don’t shake hard.
Note the mixing date and store at 2–8 °C (35.6–46.4 °F), shielded from light.
Both concentrations keep each dose within a single U-100 syringe. Pick the ~1,667 mcg/mL mix for moderate once-daily dosing, or the ~2,500 mcg/mL mix for compact volumes when injecting twice daily.
Supplies Needed
Quantities below assume a 4–8 week course of daily injections at a moderate dose.
A single 5 mg vial covers part of a moderate daily protocol; higher or twice-daily dosing uses more.
- 6 weeks (200–300 mcg/day): ~2 vials
- 8 weeks (200–300 mcg/day): ~3 vials
- Advanced (250 mcg, 2×/day): ~6 vials
- Per injection: 1 syringe
- 8 weeks (once daily): ~56 syringes
- 8 weeks (twice daily): ~112 syringes
Use 3.0 mL (standard) or 2.0 mL (advanced) per 5 mg vial for reconstitution.
- 4 weeks (1–2 vials): 3–6 mL → 1 bottle
- 8 weeks (2–3 vials): 6–9 mL → 1 × 30 mL bottle
One for the vial stopper + one for the injection site each time.
- Per injection: 2 swabs
- 8 weeks (once daily): ~112 swabs → 1–2 boxes
Dosing Protocol
A suggested daily injection approach based on common reference doses.
- ▪Start: Begin around 200 mcg per day to gauge tolerability, then adjust as needed.
- ▪Cycle Length: Typically 4–8 weeks; some references extend to ~12 weeks.
Storage Instructions
Correct storage is what preserves the peptide’s stability and potency.
- ▪Lyophilized: Hold the dry vial frozen at −20 °C (−4 °F) until mixing; shield from moisture and light[11].
- ▪Reconstituted: Chill at 2–8 °C (35.6–46.4 °F) as soon as it’s mixed and use within ~30 days[11].
- ▪Handling: Let frozen vials warm to room temperature before opening so condensation won’t form; keep the solution clear of heat and direct light.
- ▪Freeze–thaw: Avoid repeated freeze–thaw cycles, which degrade the peptide[12].
Important Notes
Practical points that keep daily administration safe and consistent.
- ▪Daily consistency: Space injections evenly and keep to a steady schedule for the whole protocol.
- ▪Higher-frequency dosing: For advanced schedules, split the daily total across two or more injections rather than one large volume.
- ▪Side-effect monitoring: Watch for injection-site discomfort, headache or nausea; consult a professional if concerns arise, and consider cycling off after ~8 weeks.
How This Works
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide — a 15-amino-acid sequence derived from a protein found in gastric juice[3]. Nearly all of the evidence behind it comes from animal and in-vitro (preclinical) studies, not from completed human efficacy trials.
In those preclinical models it has been reported to promote angiogenesis — the growth of new blood vessels — through the VEGFR2–Akt–eNOS / nitric-oxide pathway, which may help explain its observed effects on healing[1][4].
Animal research has also described accelerated repair of tendon, ligament, muscle, bone and gut tissue, alongside cytoprotective and anti-inflammatory activity — particularly protection of the gastrointestinal lining[2][4].
Important caveat: human efficacy is unproven. The evidence base is overwhelmingly preclinical, and there are no completed, published Phase 2 or 3 human efficacy trials — only early-stage safety work[9]. Reported mechanisms should be read as hypotheses from laboratory and animal data.
BPC-157 is not an approved medicine. It is an unapproved research chemical presented here for research and educational purposes only and is not approved for general human use.
Lifestyle Factors
Habits that may support recovery alongside the protocol.
- ▪Nutrition: Eat a balanced, protein-forward diet to give tissue repair the building blocks it needs.
- ▪Activity & rest: Combine appropriate movement with adequate rest so healing tissue can recover.
- ▪Hydration: Keep fluids up across the protocol.
- ▪Sleep & stress: Aim for solid sleep and manage stress, both of which support recovery.
Potential Benefits & Side Effects
What preclinical research and anecdotal reports describe; human evidence is limited and individual results vary.
Potential Benefits
- ▪Tissue repair (preclinical): Animal studies report faster tendon, ligament, muscle and bone healing[4].
- ▪GI protection (preclinical): Reported cytoprotective effects on the gastrointestinal lining in animal models[2].
- ▪Anti-inflammatory signalling: Preclinical anti-inflammatory and angiogenic activity has been described[1].
- ▪Note on humans: These benefits are not established in humans — no completed Phase 2/3 efficacy trials exist.
Common Side Effects
- ▪Injection-site reactions: Discomfort, redness or soreness at the site can occur; rotating sites helps.
- ▪Other reported effects: Headache and nausea have been noted anecdotally.
- ▪Unknown long-term profile: Long-term human safety data is limited; caution and monitoring are advised.
Injection Technique
Subcutaneous (or intramuscular) injection technique, following established clinical practice and CDC guidance[13][14].
Pre-Injection Preparation
- ▪Wash your hands well with soap and water[14].
- ▪Wipe the vial stopper with an alcohol swab and let it air-dry.
- ▪Pick a site (abdomen, thigh, or upper arm) and wipe it with a fresh alcohol swab, letting it dry fully[13].
- ▪Carefully draw the intended dose, then check for air bubbles and push any out.
Injection Procedure
- ▪Pinch about a 1-inch fold of skin between thumb and forefinger[15].
- ▪Insert the needle into the pinch at a 45–90-degree angle (use 45 degrees if the fat layer is thin)[13][14].
- ▪Skip aspiration for subcutaneous shots — it isn’t needed and can add discomfort[13].
- ▪Press the plunger slowly and steadily until it’s fully down.
- ▪Pull the needle straight out and, if needed, press lightly with clean gauze.
Post-Injection Care
- ▪Drop the used syringe straight into a puncture-proof sharps container — never recap a needle[14].
- ▪Put the reconstituted vial back in the fridge right away.
- ▪Rotate the site with each injection (at least 1 inch over) to prevent irritation[15].
- ▪Watch the site for excess redness, swelling, or signs of infection.

BPC-157 — frequently asked questions
How do I reconstitute a 5 mg vial of BPC-157?
Wipe the stopper with an alcohol swab, then inject your bacteriostatic water slowly down the inside wall of the vial. Let it sit and gently swirl until dissolved — never shake. Store the mixed vial in the refrigerator and draw doses with an insulin syringe. Use the calculator above to turn any dose into syringe units.
How much bacteriostatic water should I add to BPC-157?
There is no single correct amount — more water simply spreads the same 5 mg of peptide across a larger volume, which makes small doses easier to measure accurately. 1 to 3 mL per vial is typical. Enter your chosen volume in the calculator above to see the resulting concentration and syringe units.
What do the "units" on an insulin syringe mean?
On a U-100 insulin syringe, 100 units equal 1 mL, so 1 unit equals 0.01 mL. The calculator above converts your draw volume into these units automatically so you can measure without doing the math by hand.
How should I store BPC-157 after mixing?
Keep the reconstituted vial refrigerated at roughly 2 to 8 degrees Celsius, away from light, and avoid freezing it. Reconstituted research peptides are generally used within a few weeks. Always follow the specific guidance supplied with your product.
How many doses does a 5 mg vial of BPC-157 provide?
Divide the vial strength of 5 mg by the amount you use per injection. The calculator above reports this as "doses per vial" the moment you enter a dose.
Is BPC-157 approved for human use?
No. BPC-157 is sold strictly for laboratory and research purposes and is not approved by the FDA or other regulators for human use. Everything on this page is research information, not medical advice — consult a licensed healthcare professional before any use.
