BPC-157 Dosing Protocol: Ranges, Frequency, and Duration
Common BPC-157 dose ranges (200–500 mcg), once-daily vs twice-daily frequency rationale, typical protocol durations for injury vs GI use, units-to-draw reference table, and why fasting is not required.

What BPC-157 dosing protocols look like in practice
BPC-157 dosing protocols vary by prescriber, use case, and the animal literature being extrapolated from. There is no FDA-approved human dosing; the ranges below are from research protocols and practitioner reports. Your prescribing provider's instructions take precedence over any general reference.
Common dose ranges
| Protocol type | Dose per injection | Frequency | Total daily dose |
|---|---|---|---|
| Low / conservative | 200–250 mcg | Once daily | 200–250 mcg/day |
| Standard | 250–500 mcg | Once daily | 250–500 mcg/day |
| Twice daily | 250 mcg | Twice daily (AM + PM) | 500 mcg/day |
| Acute injury (early phase) | 250–500 mcg | Twice daily | 500–1,000 mcg/day |
The most commonly reported starting protocol is 250 mcg once daily. Some practitioners prefer twice-daily for acute injury in the first 2–4 weeks, then stepping down to once daily.
Why twice-daily doesn't mean double the effect
BPC-157 has a ~4-hour half-life. With once-daily dosing, the compound is effectively cleared within 20 hours — less than 3% remains by the next dose. Twice-daily dosing provides a second peak ~12 hours after the first, maintaining higher active levels during the day. Whether the second pulse provides meaningfully different outcomes than once-daily is not well established in human data.
The rationale for twice-daily in acute injury contexts: the tissue repair process is continuous, and maintaining active levels during both waking and sleeping periods may be advantageous during the acute phase. Once healing progresses and the acute phase passes, many protocols step down to once daily.
Protocol duration
Typical protocol durations from practitioner reports:
- Acute injury: 4–12 weeks, sometimes longer for significant musculoskeletal injuries. Protocol typically continues until injury resolution or plateau.
- GI applications: 4–8 weeks commonly reported; some practitioners run maintenance doses indefinitely for chronic GI conditions.
- General use / stacked with other compounds: Varies widely. Some practitioners cycle (8–12 weeks on, 4–8 weeks off); others run maintenance continuously.
Long-term safety data in humans is limited. Protocol duration is a clinical decision based on your use case and your provider's judgment.
Units to draw at common doses
For a 5 mg vial + 2 mL bac water (concentration: 2,500 mcg/mL):
| Dose | Volume | Units (U100 syringe) |
|---|---|---|
| 200 mcg | 0.08 mL | 8 units |
| 250 mcg | 0.10 mL | 10 units |
| 500 mcg | 0.20 mL | 20 units |
For a different bac water volume or vial strength, use the reconstitution calculator to get the correct draw for your specific setup.
Fasting: not required for BPC-157
Unlike CJC-1295/Ipamorelin, BPC-157 does not require fasted-state injection. Its mechanism (NO signaling, VEGF, cytoprotection) is not insulin-dependent. Inject at whatever time fits your schedule — morning with other SubQ injections is common for convenience, but there is no pharmacological benefit to fasting.
Site rotation with daily dosing
Daily injection demands rotation. Injecting at the same site daily causes lipohypertrophy — fatty tissue buildup that reduces absorption. With a ~4-hour half-life and no accumulation, impaired absorption directly reduces active levels.
A 6-site rotation (left/right abdomen × 2 zones, left/right thigh) gives 6 days between returns to any single site. Log each injection site so you can track which sites have been used recently. See the injection site rotation guide for the full zone map.
Frequently asked questions
- How much BPC-157 should I take per day?
- Common practitioner protocols range from 200–500 mcg once daily to 250–500 mcg twice daily for acute injury phases. The most frequently reported starting dose is 250 mcg once daily. There is no FDA-approved human dosing — follow your prescribing provider's instructions, which may differ from general community ranges.
- How long should a BPC-157 protocol last?
- Depends on the use case. Acute injury protocols typically run 4–12 weeks. GI applications commonly run 4–8 weeks. Some practitioners use maintenance dosing for chronic conditions. Protocol duration is a clinical decision for your provider based on your specific situation and response.
- Is once-daily or twice-daily BPC-157 better?
- No head-to-head human data compares the two. Twice-daily provides a second concentration peak ~12 hours after the first, potentially maintaining active levels through more of the day. Some practitioners use twice-daily during acute injury phases, then step down to once-daily. Your prescribing provider determines the right frequency for your protocol.
- Do I need to fast before injecting BPC-157?
- No. BPC-157's mechanisms are not insulin-dependent, so fasted-state injection is not required. Inject at a convenient time. This is different from CJC-1295/Ipamorelin, which does require fasted-state injection to maximize GH pulse amplitude.
- How many units do I draw for 250 mcg BPC-157?
- Depends on your vial concentration. For a 5 mg vial + 2 mL bac water (2,500 mcg/mL): 250 mcg = 10 units on a U100 syringe. For 1 mL bac water (5,000 mcg/mL): 250 mcg = 5 units. Use the My Pep Calc reconstitution calculator with your actual vial and bac water volume.
