1. Draw 1 mL bacteriostatic water with a sterile syringe.
2. Inject slowly down the vial wall; avoid foaming.
3. Gently swirl until dissolved (do not shake).
4. Label and refrigerate at 2 to 8 °C, protected from light. At 10 mg/mL, 1 unit = 0.01 mL » 100 mcg on a U-100 insulin syringe.

BPC-157 is a synthetic peptide corresponding to a partial sequence of human gastric juice protein. Preclinical studies suggest it modulates nitric oxide pathways and growth-factor expression to promote angiogenesis and collagen deposition in damaged tissues. Animal models report accelerated healing of gut, tendon, ligament, and muscle injuries. A Phase I oral safety trial has been completed, and a small human case series reported improvements following intra-articular administration; however, large-scale controlled human efficacy data are not yet available.

• Supports tissue repair in gut, tendon, muscle, and skin injury models (animal data).
• Demonstrates anti-inflammatory and cytoprotective properties in preclinical settings.
• Phase I safety studies report good tolerability with no serious adverse events at tested doses.
• Occasional mild injection-site reactions (redness, itch) may occur with subcutaneous administration.
• Long-term human safety and efficacy remain under investigation.
