BPC-157 dosing is mostly about reco math + injection technique, get either wrong and your 250 mcg pin is actually 500 mcg on the same syringe mark. The math depends entirely on vial size and how much BAC water you added. This page runs the exact numbers for BPC-157's two common vial sizes (5 mg and 10 mg lyo) and includes a dose-to-units reference table plus a free calculator pre-filled with a typical reco protocol.
Key Takeaways
- —BPC-157 ships as 5 mg or 10 mg lyo vials. 2 mL of BAC water is the standard diluent for both.
- —Reco concentrations: 2,500 mcg/mL (5 mg vial) or 5,000 mcg/mL (10 mg vial).
- —The community-standard 250 mcg pin = 10 units on a U-100 slin pin (5 mg vial reco'd with 2 mL BAC).
- —A 5 mg vial yields 20 doses at 250 mcg; a 10 mg vial yields 40. A 6-week run at 250 mcg subq 2x/day needs 2x 5 mg vials or 1x 10 mg vial.
- —Reco'd solution holds 28 days at 2-8°C (Next Pep BPC-157 profile).
| Vial Size | BAC Water | Concentration | Notes |
|---|---|---|---|
| 5 mg | 2 mL | 2,500 mcg/mL | Most common; 10 units = 250 mcg |
| 5 mg | 1 mL | 5,000 mcg/mL | Double concentration; 5 units = 250 mcg |
| 10 mg | 2 mL | 5,000 mcg/mL | Most common for 10 mg vials |
| 10 mg | 4 mL | 2,500 mcg/mL | Matches 5 mg / 2 mL draw volumes |
Remember: a 5 mg vial means TOTAL, not per dose. The 5 mg + 2 mL reco is the default most protocols reference because it gives clean syringe marks for the 200-500 mcg range. Swirl gently after adding BAC water, don't shake.
Assuming a U-100 slin pin (100u = 1mL). All numbers below are for the standard 2,500 mcg/mL concentration (5 mg vial + 2 mL BAC water):
| Target Dose | Draw Volume | U-100 Units |
|---|---|---|
| 100 mcg | 0.04 mL | 4 units |
| 150 mcg | 0.06 mL | 6 units |
| 200 mcg | 0.08 mL | 8 units |
| 250 mcg | 0.10 mL | 10 units |
| 300 mcg | 0.12 mL | 12 units |
| 400 mcg | 0.16 mL | 16 units |
| 500 mcg | 0.20 mL | 20 units |
For the double-concentration 5,000 mcg/mL variant (10 mg + 2 mL, or 5 mg + 1 mL), halve the unit count: 250 mcg = 5 units, 500 mcg = 10 units.
The formula's straightforward: total cycle mg = daily dose mcg x doses per day x cycle length in days / 1,000.
Common BPC-157 protocols translated to vial counts:
| Protocol | Total Dose | 5 mg vials | 10 mg vials |
|---|---|---|---|
| 250 mcg subq 1x/day x 4 weeks | ~7 mg | 2 | 1 |
| 250 mcg subq 2x/day x 6 weeks | ~21 mg | 5 | 3 |
| 500 mcg subq 2x/day x 8 weeks | ~56 mg | 12 | 6 |
Always round up. Lyo vials hold for years at -20°C, so extra inventory isn't wasted, but running short mid-cycle means a repeat order and the 28-day rule clock resets on the new vial when you reco it.
The dosing calculator at /dosing-calculator supports deep-links, the link above opens the calculator with BPC-157's most common protocol already loaded (5 mg vial, 2 mL BAC water, 250 mcg target). It shows you draw volume in mL and slin pin units in real time as you adjust any input.

Three BPC-157-specific reco mistakes that show up over and over in posts:
For the typical 5 mg vial reco'd with 2 mL of BAC water (2,500 mcg/mL): 250 mcg = 10 units, 500 mcg = 20 units on a U-100 slin pin. Always recalculate if you switch vial size or BAC volume, the math doesn't carry across.
2 mL is the standard default, gives you 2,500 mcg/mL and clean syringe marks for 200-500 mcg pins. 1 mL doubles concentration to 5,000 mcg/mL; some people prefer it to cut injection volume, but small draws get harder to read accurately.
No. BAC water has 0.9% benzyl alcohol as a preservative, without it any multi-dose vial is bacterially contaminated within 24-72 hours of reco. Single-use draws can run sterile saline but you're wasting most of a 5 mg vial that would otherwise yield 20 doses.
28 days refrigerated at 2-8°C. Never freeze reco'd solution, freeze-thaw cycles wreck the peptide structure. Slap a date sticker on the vial when you first puncture it; toss after 28 days regardless of how it looks.
No formal upper-bound has been established in human trials, a 2025 IV safety study pushed up to 20 mg without adverse events in two volunteers. Community standard sits at 250 mcg subq 1-2x/day for 4-8 weeks, with total daily doses up to 1 mg split across multiple sites for stubborn injuries.

CJC-1295 with DAC has a 6-8 DAY half-life; Modified GRF (1-29) clears in ~30 minutes. Same modified GHRH(1-29) backbone, one bolt-on linker, ~1,000x PK difference.
TB-500 is a 7-aa fragment of thymosin beta-4 (43 aa, ~4,963 Da), not the full protein. Cross-COA review: ~67% of "TB-500" vials are actually full Tβ4.
