BPC-157 Dosage Calculator

Quick Reference: 5mg Vial + 2mL BAC Water

BPC-157 (Body Protection Compound-157) is a synthetic peptide derived from a protein found in human gastric juice. It has been extensively studied for its regenerative and healing properties, with over 100 published research papers covering tendon repair, gut healing, and neuroprotection.

Step-by-Step Reconstitution

• Step 1: Gather supplies — BPC-157 vial (typically 5mg), bacteriostatic water, insulin syringe, and alcohol swabs
• Step 2: Clean the tops of both vials with alcohol swabs and let dry
• Step 3: Draw 2mL of bacteriostatic water into the syringe
• Step 4: Insert needle into BPC-157 vial at a slight angle
• Step 5: Slowly inject water down the inside wall — never spray directly onto the powder
• Step 6: Gently swirl (do not shake) until fully dissolved — should be clear
• Step 7: Store in refrigerator (2-8°C). Use within 2-4 weeks

Storage & Stability

Unreconstituted (lyophilized) BPC-157 can be stored at room temperature for months, or frozen for years. Once reconstituted with bacteriostatic water, refrigerate and use within 14-28 days. Never freeze reconstituted peptides.

Injection Sites

BPC-157 is most commonly administered via subcutaneous injection. For localized injuries (tendons, muscles, joints), inject as close to the injury site as possible. For systemic or gut-related benefits, inject into abdominal fat. Rotate injection sites to prevent tissue irritation.

BPC-157 (Body Protection Compound-157) is a 15-amino-acid synthetic peptide derived from a protective protein found naturally in human gastric juice. Since its discovery, BPC-157 has been the subject of over 100 peer-reviewed studies, primarily in animal models, covering a wide range of regenerative and cytoprotective effects.

Key areas of research

Mechanism of action

BPC-157 appears to work through multiple pathways simultaneously. Research suggests it upregulates growth factor expression (including VEGF, EGF, and FGF), modulates the nitric oxide system, and interacts with the FAK-paxillin pathway involved in cell migration and tissue repair. Unlike many peptides that target a single receptor, BPC-157's broad mechanism may explain its effects across different tissue types — from gut mucosa to tendons to neural tissue.

It is important to note that the vast majority of BPC-157 research has been conducted in animal models (primarily rats). Human clinical trials are limited, and results from animal studies do not always translate directly to humans. For a deeper understanding of peptide preparation, see our complete reconstitution guide.

Some researchers combine BPC-157 with complementary peptides to address multiple aspects of tissue repair simultaneously. Below are the most commonly discussed combinations in the research community.

BPC-157 + TB-500 (Thymosin Beta-4)

This is the most popular healing peptide stack. BPC-157 and TB-500 appear to work through different but complementary mechanisms — BPC-157 primarily through angiogenesis and growth factor modulation, while TB-500 promotes cell migration and reduces inflammation through actin sequestration.

BPC-157 + GHK-Cu

GHK-Cu (copper peptide) is primarily studied for skin remodeling, collagen synthesis, and anti-inflammatory effects. Combined with BPC-157, this stack targets both deep tissue repair and surface-level wound healing.

Both BPC-157 and TB-500 can be reconstituted using standard procedures. Use our peptide calculator to determine exact syringe units for each peptide in your protocol.

BPC-157 is relatively stable compared to many other research peptides, but proper handling is still essential for maintaining potency throughout your research period.

Storage guidelines by form

Handling best practices

• Light sensitivity: BPC-157 shows minimal photodegradation compared to peptides like MT-II, but storing in the original amber vial or wrapping in foil is still recommended.
• pH stability: BPC-157 is remarkably stable across a wide pH range (pH 2-10), which contributes to its effectiveness when taken orally (surviving stomach acid).
• Freeze-thaw cycles: Avoid repeated freezing and thawing of reconstituted solution. Each cycle can cause partial denaturation. If storing long-term, consider splitting into multiple aliquots before freezing the lyophilized form.
• Reconstitution clarity: Properly reconstituted BPC-157 should be completely clear. Any cloudiness, particles, or discoloration indicates contamination or degradation — discard the vial.
