Body Protection Compound

BPC-157

A synthetic pentadecapeptide derived from a protective protein found in human gastric juice. One of the most-researched peptides in animal models for tissue repair, gut healing, and systemic recovery.

◆ Evidence Level: Primarily Animal ResearchThe majority of BPC-157 research comes from animal models. Only 3 small human pilot studies exist, totaling approximately 30 subjects. No randomized controlled trials have been published. See references →

What Is BPC-157?

BPC-157 (Body Protection Compound-157) is a 15-amino acid synthetic peptide derived from a larger protective protein found naturally in human gastric juice. It was first isolated from the stomach lining, where it plays a role in mucosal protection and gut repair.^[2]

In research settings, BPC-157 has demonstrated tissue-healing properties across multiple systems in animal studies^[1] – tendons, ligaments, muscles, the GI tract, and even the nervous system. It is one of the few peptides studied for both injectable (subcutaneous) and oral administration.

Mechanism of Action

BPC-157 operates through several interconnected repair pathways:

Angiogenesis: Promotes new blood vessel formation at injury sites, accelerating nutrient delivery and waste removal
Growth factor modulation: Upregulates VEGF, EGF, and other growth factors critical to tissue regeneration
Nitric oxide system: Interacts with the NO system to regulate blood flow, inflammation, and vascular tone
Tendon and ligament repair: Stimulates fibroblast migration and collagen production at connective tissue injury sites
Gut mucosal protection: Counteracts mucosal damage from NSAIDs, alcohol, and stress-induced lesions
Neuroprotective effects: Supports dopaminergic and serotonergic system function in animal models

Research Applications

Tendon, ligament, and muscle injury repair acceleration
Gut healing: IBS, leaky gut, NSAID-induced ulcer models
Post-surgical recovery and wound healing
Neuroprotection and traumatic brain injury research
Counteracting organ damage from toxins and medications
Synergistic stacking with TB-500 for systemic recovery protocols

Dosing Protocol

BPC-157 can be administered subcutaneously (near the injury site for localized effect) or orally (for gut-related applications). Dosing reflects commonly reported research protocols:

Protocol	Dose	Frequency	Notes
Standard SubQ	250–500 mcg	1–2x daily	Inject near injury site when possible
Systemic SubQ	500 mcg	Once daily	Abdominal SubQ for general healing
Oral (gut focus)	250–500 mcg	1–2x daily	On empty stomach for GI applications

For localized injuries, inject as close to the site as practical. Oral dosing is primarily used for gut-related protocols. Typical research cycles run 4–12 weeks. BPC-157 is frequently stacked with TB-500 for enhanced systemic recovery.

Preparation & Storage

Reconstitution

Supplies: peptide vial, bacteriostatic water, insulin syringes (29–31 gauge), alcohol swabs.

Clean both vial tops with alcohol swabs and let dry
Draw 2 mL of bacteriostatic water into the syringe
Insert needle into peptide vial at an angle against the glass wall
Let water run slowly down the side – never squirt directly onto powder
Gently swirl until fully dissolved – never shake
Solution should be clear – discard if cloudy or contains particles

Concentration: 10 mg in 2 mL = 5,000 mcg/mL

Storage

Unreconstituted: Room temp or refrigerated, stable up to 24 months
Reconstituted: Refrigerate at 2–8°C (36–46°F), use within 4–6 weeks
Protect from direct sunlight and heat
Do not freeze reconstituted solution

Cycling

Typical research cycle: 4–12 weeks. Results generally reported within 1–2 weeks.
