Complete BPC-157 dosing reference — how to reconstitute, optimal doses for different goals, injection sites, and what the research shows.

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide with an exceptional safety profile and extensive preclinical research showing accelerated healing across multiple tissue types. Here's how to dose and use it correctly.

What the Research Shows

BPC-157 is derived from a protein found in human gastric juice. Unlike many peptides that have only animal data, BPC-157's parent compound has a long history of human gastric secretion research. The synthetic form has been studied in hundreds of animal trials showing:

Standard Dosing Protocol

Systemic (whole-body) healing

Dose: 250 mcg, twice daily (morning and evening)
Route: SubQ (subcutaneous) injection — abdomen is easiest
Timing: On an empty stomach if possible
Cycle: 4–12 weeks

Local injury healing

Dose: 200–400 mcg, once or twice daily
Route: IM (intramuscular) injection near the injured site
Example: Rotator cuff injury → inject into the shoulder muscle near the damaged area
Note: Local IM creates higher local concentrations at the injury site

Gut healing (IBD, ulcers, leaky gut)

Dose: 250 mcg, twice daily
Route: SubQ OR oral (capsule/dissolved in water) — BPC-157 survives stomach acid, which is rare among peptides
Oral option: Dissolve reconstituted BPC-157 in a small amount of water and drink on empty stomach

How to Calculate Your Syringe Draw

The calculation depends on how much BAC water you added to your vial:

Formula: Draw (IU) = Dose (mcg) ÷ Concentration (mcg/mL) × 100

Example: 5 mg vial + 2 mL BAC water = 2,500 mcg/mL. For 250 mcg dose: 250 ÷ 2,500 × 100 = 10 IU on your syringe.

Reconstitution: Step by Step

  1. Swab the rubber stoppers of both vials with alcohol
  2. Draw 2 mL of bacteriostatic water into an insulin syringe
  3. Tilt the BPC-157 vial at 45° and inject water slowly down the glass wall
  4. Gently swirl — never shake — until fully dissolved
  5. Label with date and concentration (e.g., "BPC-157 2,500 mcg/mL — 3/25/26")
  6. Store refrigerated at 2–8°C — stable for 28–30 days

BPC-157 + TB-500 Stack

The most popular healing stack combines BPC-157 with TB-500 (Thymosin Beta-4 fragment). They work via different mechanisms — BPC-157 promotes angiogenesis and GH receptor upregulation while TB-500 regulates actin and drives cell migration — creating synergistic healing effects. Typical stack: BPC-157 250 mcg 2×/day SubQ + TB-500 2.5 mg 2×/week SubQ.

Frequently Asked Questions

What is a typical BPC-157 starting dose?
Most research protocols use 200-300 mcg (micrograms) once or twice daily, which translates to roughly 2.5-5 mcg per kilogram of body weight. Starting at the lower end allows you to assess tolerance before increasing. Doses above 500 mcg twice daily are uncommon in the available literature and not well-studied in humans.
How do I calculate BPC-157 dose from a reconstituted vial?
Divide the total peptide amount (usually 5 mg or 5,000 mcg) by the volume of bacteriostatic water added. For example, adding 2 mL of water to a 5 mg vial gives a concentration of 2,500 mcg/mL. For a 250 mcg dose, you would draw 0.1 mL (10 units on an insulin syringe). Use the Reconstitution Guide for step-by-step instructions.
Should BPC-157 be taken subcutaneously or intramuscularly?
Both subcutaneous and intramuscular injections are used in research settings. Subcutaneous injection near the site of injury is the most common approach in anecdotal reports. Some researchers also study oral administration, though bioavailability differs significantly between routes. The optimal route depends on the specific application being studied.
How long does a typical BPC-157 research cycle last?
Most protocols in the available literature run 4-6 weeks for injury-related research and 2-4 weeks for other applications. Some researchers extend to 8-12 weeks for chronic conditions. Cycling with equal time on and off is a common approach, though long-term safety data in humans is limited.
Does BPC-157 need to be refrigerated after reconstitution?
Yes. Once reconstituted with bacteriostatic water, BPC-157 should be stored in the refrigerator at 36-46 degrees F (2-8 degrees C). Reconstituted peptides typically remain stable for 3-4 weeks under proper refrigeration. Never freeze reconstituted peptides. See the Peptide Storage Guide for complete handling instructions.
