BPC-157 dosage calculator.

The BPC-157 dosing literature is mostly animal studies extrapolated to human research protocols. The two figures most-cited:

• 250 mcg/day — lower-end research-protocol dose, cited in multiple gastrointestinal-injury and tendon-healing rodent studies extrapolated to human research.
• 500 mcg/day — upper-end research-protocol dose, sometimes split into two 250 mcg administrations per day.
• ~2.5 mcg/kg/day — body-weight-scaled reference, derived from the rodent-study dose ranges. For an 80 kg subject this rounds to roughly 200 mcg/day; for 100 kg, 250 mcg.

These figures are research-protocol references, not clinical dosing instructions. BPC-157 is not FDA-approved for any human indication. The studies that produced these dose ranges are preclinical or limited-protocol.

Why 5 mg vials are common

Vendor catalogs cluster heavily on 5 mg and 10 mg BPC-157 vials. At a 250 mcg daily reference dose, a 5 mg vial yields 20 doses; a 10 mg vial yields 40. The 5 mg / 2 mL reconstitution at 250 mcg dose is 10 IU on an insulin syringe — a measurable, clean dose-volume that landed as the de facto research-protocol standard.

Reconstitution specifics

BPC-157 is stable in bacteriostatic water at refrigerator temperature (2–8°C) for up to 30 days post-reconstitution. Freezing reconstituted material is generally not necessary at standard-volume vials. Protect from light. The peptide is unusually stable for its class, which is part of why research-protocol literature frequently uses it as a proof-of-concept compound.
