BPC-157

Quickstart highlights

Dosing & reconstitution guide

Standard protocol (2 mL = 2,5 mg/mL)

A 5 mg vial dissolved in 2 mL bacteriostatic water gives a concentration of 2,5 mg/mL. Calculate your own dilution →

Reconstitution steps

1. Let the vial reach room temperature and wash your hands.
2. Disinfect both rubber stoppers with an alcohol swab.
3. Draw up 2 mL of bacteriostatic water.
4. Inject the water slowly down the glass wall, not directly onto the powder.
5. Swirl gently until clear — never shake.
6. Label the vial with date and concentration and refrigerate.

Supplies needed

• BPC-157 vial (5 mg)
• Bacteriostatic water
• Mixing syringe (1–3 mL) and U-100 insulin syringes
• Alcohol swabs and sharps container

Important notes

How this works

BPC-157 (Body Protection Compound-157) is a synthetic peptide consisting of 15 amino acids. The structure is derived from a protein found naturally in human gastric juice. It is studied for its potential protective and restorative properties throughout the body.

In preclinical studies, BPC-157 influences nitric oxide signaling, which helps relax blood vessels and regulate blood flow. It stimulates the expression of vascular endothelial growth factor (VEGF), leading to the formation of new blood vessels. This process, known as angiogenesis, is important for delivering nutrients to damaged tissue. Additionally, the peptide affects the function of fibroblasts, the cells responsible for collagen production in tendons and ligaments. Unlike many other growth factors, BPC-157 is relatively stable in gastric acid. The exact half-life in humans has not been definitively established, but in animal models, the compound acts briefly and locally.

Research into BPC-157 is largely in the preclinical phase, with extensive rat and mouse studies focusing on muscle, tendon, and gut wall repair. A Phase I human safety trial for inflammatory bowel disease has been completed, and small case reports exist regarding joint applications. Despite these findings, large-scale placebo-controlled clinical trials proving efficacy in humans are missing. BPC-157 is currently not an approved medicine and is on the WADA list of prohibited substances for athletes. It remains a research compound with unanswered questions regarding long-term safety.

Potential benefits & side effects

Effects described in research

• Support of tendon and ligament repair (animal studies)
• Protection of gastric and intestinal lining
• Stimulation of angiogenesis
• Possible anti-inflammatory effect

Common side effects

• Injection-site redness or itch
• Mild nausea
• Dizziness

Side effects in early studies are limited to mild complaints such as nausea, dizziness, or injection site irritation. Since no large-scale long-term human research has been conducted, the risks of prolonged use are unknown. Theoretically, stimulating new blood vessels could pose risks in certain existing conditions, but this has not been confirmed in clinical research.

Contraindications

• Pregnancy or breastfeeding
• Active or prior cancer
• Under 18 years of age

Lifestyle factors

• Pair with progressive loading and rehab-style exercise.
• Adequate protein (1.6–2 g/kg) and sleep support tissue repair.
• Some protocols avoid NSAIDs as they may slow repair.

Injection technique

• Choose a site with subcutaneous fat: abdomen (5 cm from the navel), thigh or back of upper arm.
• Disinfect, pinch a skin fold and insert at a 45–90° angle.
• Inject slowly, wait 5 seconds and withdraw.
• Rotate sites and use each needle once.

Recommended source

Quality varies widely between suppliers. Look for an independent HPLC/MS lab report per batch, purity ≥ 98% and clear storage and shipping conditions.
