The **shelf life of BPC 157** depends largely on its form and storage conditions. In its most common form, BPC 157 is supplied as a **lyophilized (freeze-dried) powder**, which is highly stable and can last **up to 24 to 36 months** when stored properly in a cool, dry place away from heat and moisture. This freeze-drying process preserves the peptide’s purity and potency over time by removing moisture that would otherwise promote degradation.
Once reconstituted (mixed with bacteriostatic water or another solvent for injection), the shelf life of BPC 157 significantly decreases. After mixing, it should be stored in a refrigerator at temperatures between **2°C and 8°C (36°F to 46°F)** to slow down peptide degradation and microbial growth. Under these refrigerated conditions, the reconstituted BPC 157 typically remains stable and effective for about **4 weeks**. It is important to avoid freezing the reconstituted solution because freeze-thaw cycles can reduce its efficacy.
During storage, whether as powder or solution, it is crucial to monitor the peptide for any changes such as discoloration, cloudiness, or precipitation, which may indicate contamination or degradation and signal that the peptide should no longer be used.
To summarize the key points about BPC 157 shelf life:
– **Lyophilized powder form:** Stable for **24 to 36 months** when kept sealed, dry, and refrigerated or frozen at around -20°C.
– **Reconstituted solution:** Stable for about **4 weeks** when refrigerated at 2–8°C; avoid freezing after reconstitution.
– **Storage tips:** Keep away from heat, moisture, and light; avoid repeated freeze-thaw cycles; use sterile techniques to prevent contamination.
This stability profile makes BPC 157 convenient for long-term storage in powder form, but users must be mindful of the much shorter shelf life once it is mixed and ready for use. Proper handling and storage are essential to maintain its therapeutic potential.
