What Is BPC-157?

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide consisting of 15 amino acids. It is a partial sequence derived from a protective protein found in human gastric juice, first characterized in peer-reviewed literature in the 1990s by researchers at the University of Zagreb School of Medicine.

Unlike many peptide research compounds, BPC-157 is water-stable at physiological pH — a property that distinguishes it from most growth-hormone secretagogues and simplifies in vitro reconstitution procedures.

Research Context (Per Source Summary)

Note: The following is a neutral summary of findings published in peer-reviewed journals. All studies referenced were conducted in animal models or cell culture (in vitro). No human clinical trials have been completed.

Published pre-clinical research has examined BPC-157 in the context of:

  • Tendon & ligament healing — accelerated recovery in rat Achilles tendon transection models (Staresinic et al., J. Orthopaedic Res., 2003)
  • Gastrointestinal protection — cytoprotective effects in NSAID-induced gastric ulcer models (Sikiric et al., Curr. Pharm. Des., 2018)
  • Wound healing — enhanced collagen synthesis and angiogenesis markers in excisional wound models
  • Neurological research — dopamine system modulation studied in rodent models (Sikiric et al., J. Physiol. Pharmacol., 2016)

Proposed mechanisms in the literature include upregulation of growth hormone receptor expression and activation of the FAK-paxillin pathway relevant to cell migration.

Reconstitution Mathematics

Accurate reconstitution is critical for consistent dosing in any laboratory protocol. The interactive calculator on this page handles all the arithmetic — but understanding the underlying formula is useful for verification:

Concentration (mg/mL) = Vial Size (mg) ÷ BAC Water Added (mL)
Dose Volume (mL)      = Desired Dose (mg) ÷ Concentration (mg/mL)
Syringe Units (IU)    = Dose Volume (mL) × 100   [for U-100 insulin syringe]

Common laboratory reconstitution examples:

Vial SizeBAC WaterConcentration250 mcg dose
5 mg2 mL2.5 mg/mL10 IU
5 mg5 mL1.0 mg/mL25 IU
10 mg2 mL5.0 mg/mL5 IU

Use the interactive calculator on this page for any custom vial size, water volume, or dose.

Stability & Storage (Laboratory Protocol)

StateTemperatureDuration
Lyophilized (dry powder)−20°C (freezer)24+ months
Reconstituted in BAC water2–8°C (refrigerator)Up to 28 days
Reconstituted, room temp20–25°C48 hours maximum

Bacteriostatic water (BAC water, 0.9% benzyl alcohol) is the standard diluent for reconstitution because benzyl alcohol acts as a preservative, extending the usable life of the reconstituted solution.

Reconstitution procedure (standard laboratory protocol):

  1. Allow vial to reach room temperature (~15 minutes)
  2. Wipe septum with 70% isopropyl alcohol
  3. Draw desired BAC water volume into a sterile syringe
  4. Insert needle at a 45° angle and inject slowly along the vial wall — do not inject directly onto the lyophilized cake
  5. Gently swirl (do not shake or vortex) until fully dissolved
  6. Label vial with date and store per table above

Frequently Asked Questions

How many units do I draw for 250 mcg of BPC-157?

It depends on your reconstitution ratio. With a 5 mg vial in 2 mL BAC water (2.5 mg/mL concentration), a 250 mcg dose = 10 units on a U-100 insulin syringe. Use the calculator above for your specific setup.

Can BPC-157 be combined with other peptides in the same vial?

In laboratory settings, BPC-157 is sometimes studied alongside TB-500 (Thymosin Beta-4). Peptides should only be combined if their stability profiles are compatible. Use the multi-peptide mode in the calculator to compute combined injection volumes.

What is the difference between BPC-157 Acetate and BPC-157 Arginine Salt?

The arginine salt form is reported to have improved water solubility. Both are the same active peptide sequence; the counterion affects dissolution speed but not the reconstitution mathematics presented above.

What concentration is standard for BPC-157 laboratory protocols?

Published rodent studies most commonly report doses expressed per kilogram body weight. The calculator above is designed for computing human-scale reconstitution mathematics for reference purposes only.
