Complete BPC-157 dosage guide covering research protocols, reconstitution, injection timing, and cycling.
BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in gastric juice. It is one of the most studied research peptides for tissue repair, with a well-established dosing range across preclinical and anecdotal human research.

| Protocol | Dose | Notes |
|---|---|---|
| Conservative | 250mcg/day | Starting dose for new researchers. Effective for systemic effects and gut healing. |
| Standard | 500mcg/day | Most commonly reported dose. Split into 2x 250mcg injections for consistent blood levels. |
| High | 1000mcg/day | Used for acute injury protocols. Not recommended for extended periods. |
Reconstitute with bacteriostatic water. For a 5mg vial: add 2.5mL BAC water for a concentration of 2mcg/μL (200mcg per 0.1mL/10 units on a 100-unit insulin syringe).
Twice daily injections (morning and evening) maintain more stable blood levels than a single daily dose. For gut healing, oral administration in water is also used.
Typically run for 4–12 weeks. A 4-week break between cycles is common, though some researchers run it continuously for chronic conditions.
Lyophilized powder: refrigerate at 2–8°C. Reconstituted: refrigerate, use within 30 days.

The most commonly reported research dose is 250–500 mcg per day, split into two injections. 500 mcg/day is the standard for injury protocols. Oral administration typically uses 500 mcg–1 mg per day in divided doses.
Add bacteriostatic water slowly to the lyophilized powder. For a 5 mg vial, 2.5 mL of BAC water gives a concentration of 2 mcg/μL — 250 mcg = 0.125 mL = 12.5 units on a 100-unit syringe. Store reconstituted peptide refrigerated and use within 30 days.
Most protocols run 4–12 weeks. Acute injury protocols often see results within 4–6 weeks. Chronic conditions may benefit from longer cycles of 8–12 weeks, followed by a 4-week break before resuming.
Injectable BPC-157 produces systemic effects and is preferred for tendon, muscle, and joint injuries. Oral BPC-157 is preferred for gut-related conditions (leaky gut, SIBO, IBD) as it acts locally in the GI tract. Both routes are used in research.
Most research protocols inject BPC-157 twice daily — once in the morning and once in the evening — to maintain stable plasma levels. Injecting near the site of injury (local injection) is preferred for musculoskeletal conditions.
Yes — BPC-157 and TB-500 are commonly stacked in research protocols for synergistic injury recovery. BPC-157 promotes angiogenesis and collagen synthesis locally, while TB-500 promotes systemic tissue repair via actin regulation. The combination is often called the 'healing stack.'
Research subjects typically report initial effects within 1–2 weeks for acute injuries. Gut healing protocols show measurable improvement in 2–4 weeks. Full tendon and ligament repair typically requires 6–12 weeks of consistent dosing.
BPC-157 has a favorable safety profile in animal studies with no observed toxicity at research doses. The most commonly reported effects are mild nausea and dizziness, which are transient and typically resolve within the first week. No serious adverse events have been reported at standard research doses.
