The other possibility is that your BPC 157 is from an unreliable source and is contaminated with a hormonally active substance
Storage Recommendations for Research Use: Store lyophilized BPC-157 at -20C in a sealed, desiccated environment Once reconstituted for laboratory use, maintain at 28C and utilize within established research protocol timeframes Avoid repeated freeze-thaw cycles to preserve peptide integrity for research purposes Keep away from UV light exposure during storage For reconstitution, use sterile bacteriostatic water
