How the BPC-157 Dosage Calculator Works
BPC-157 (Body Protection Compound 157) is a synthetic pentadecapeptide studied for its role in tendon, ligament, and gut tissue repair. Research-grade protocols dose it by body weight at 2–7 micrograms per kilogram per day, with the exact range determined by what you're treating. Most adults end up in the 200–500 mcg per day window, split across one or two injections.
This BPC-157 dosage calculator runs that math instantly. Enter your body weight (lbs or kg), pick your goal, choose subcutaneous injection or oral capsules, and select your vial size and BAC water volume. The calculator outputs:
- • Daily total dose in micrograms, with the recommended midpoint plus a low–high range
- • Per-injection dose after splitting across the goal's recommended frequency
- • Injection volume in milliliters based on your reconstitution ratio
- • Insulin syringe units on a standard U-100 barrel — with a visual tick-mark indicator
- • Concentration in mg/mL after reconstitution
- • Doses per vial and days per vial so you can plan reorders
BPC-157 Dosage by Goal
BPC-157 dosing isn't one-size-fits-all. Acute injuries respond to higher doses on a shorter cycle, while gut and prevention protocols use lower doses over longer windows. Here's how the five common protocols differ:
| Goal | Dose | Frequency | Duration |
| Acute Injury | 4–7 mcg/kg/day | 2× daily | 4–6 weeks |
| Chronic Injury | 3–5 mcg/kg/day | 1–2× daily | 6–8 weeks |
| Gut Health | 2–4 mcg/kg/day | 1× daily (AM) | 6–12 weeks |
| Post-Surgical Recovery | 4–7 mcg/kg/day | 2× daily | 4–8 weeks |
| General Healing & Prevention | 2–3 mcg/kg/day | 1× daily | 4 wk on / 2 wk off |

| Body Weight | Low (3 mcg/kg) | Medium (5 mcg/kg) | High (7 mcg/kg) |
| 130 lbs (59 kg) | 177 mcg | 295 mcg | 413 mcg |
| 150 lbs (68 kg) | 204 mcg | 340 mcg | 476 mcg |
| 170 lbs (77 kg) | 231 mcg | 385 mcg | 539 mcg |
| 180 lbs (82 kg) | 246 mcg | 410 mcg | 574 mcg |
| 200 lbs (91 kg) | 273 mcg | 455 mcg | 637 mcg |
| 220 lbs (100 kg) | 300 mcg | 500 mcg | 700 mcg |
| 250 lbs (113 kg) | 339 mcg | 565 mcg | 791 mcg |
Daily totals shown. Most protocols split this across two injections per day for injury recovery, or one daily dose for gut and general wellness.
BPC-157 Dosing & Usage FAQ
01How do you calculate BPC-157 dosage by body weight?
BPC-157 is dosed by body weight at 2–7 mcg per kilogram per day, depending on your goal. Multiply your weight in kg by the mcg/kg target for your goal. For example, an 80 kg person treating an acute injury at 6 mcg/kg would take 480 mcg per day, typically split into two 240 mcg injections. The calculator above does this math instantly across five common protocols.
02What is the optimal BPC-157 dosage for injury healing?
For acute injuries (sprains, tendonitis, tears), most research protocols use 4–7 mcg/kg per day split into two doses, totaling roughly 250–500 mcg daily for an average adult. Chronic injuries respond well to 3–5 mcg/kg. The calculator on this page selects the recommended midpoint and shows the full low/medium/high range for your body weight.
03What is the typical BPC-157 dose for gut health?
For gastrointestinal issues — IBS, ulcers, inflammation, or leaky gut — researchers generally use the lower end of the dose range at 2–4 mcg/kg per day, taken once daily on an empty stomach. Most adults land between 200–400 mcg/day for 6–12 weeks. Oral capsules are often preferred for gut-localized effects.
04How much BPC-157 should I take orally vs subcutaneously?
Oral BPC-157 has lower systemic bioavailability than subcutaneous injection, so capsule doses are typically about 2× higher than the injectable equivalent. The exception is gut-specific protocols, where oral dosing acts locally on the GI tract and the higher dose is intentional. The calculator above automatically adjusts when you toggle the administration route.
05How long should a BPC-157 cycle last?
Cycle length depends on your goal. Acute injuries usually heal within 4–6 weeks, chronic injuries take 6–8 weeks, post-surgical recovery runs 4–8 weeks, and gut health protocols extend 6–12 weeks. For general wellness, many researchers use 4-week cycles with 2-week breaks between them to limit receptor desensitization.
06How many doses come out of one BPC-157 vial?
It depends on vial size, your dose, and how many times you inject per day. A 5 mg (5,000 mcg) vial at a 250 mcg dose yields 20 injections — 10 days at twice daily or 20 days at once daily. The calculator shows doses per vial and days per vial for your exact configuration.
07How do I convert my BPC-157 mcg dose into syringe units?
After reconstituting, divide your dose in mcg by the concentration in mcg/mL to get volume in mL, then multiply by 100 to get units on a U-100 insulin syringe. Example: 250 mcg ÷ 2,500 mcg/mL (5 mg vial + 2 mL BAC water) = 0.1 mL = 10 units. The visualizer on this page renders the exact tick mark to draw to.
08Should I inject BPC-157 near the injury site or systemically?
Both routes work. Subcutaneous injection into the abdominal fat is the most common systemic approach — BPC-157 travels through the bloodstream to the injury. Some researchers prefer injecting closer to the affected area (e.g., near a tendon or joint) for localized effect. There is no strong consensus that one approach is superior; pick whichever is most practical.
09Is the BPC-157 dosage calculator accurate?
The math is straightforward: weight × mcg/kg × bioavailability multiplier, divided by injection frequency and the vial concentration. The calculator uses widely cited research-protocol ranges (2–7 mcg/kg/day across goals). All output is for educational and research purposes — never use it as a substitute for medical advice.
10What are common BPC-157 side effects?
Reported side effects in research subjects are generally mild and include injection-site irritation, transient nausea, fatigue, or headaches. BPC-157 has not been approved for human therapeutic use by the FDA. Anyone considering supplementation should review the current research literature with a qualified clinician.
