A user shared their protocol for self-reconstituting bulk BPC-157 powder into sterile vials for long-term subcutaneous use. They described a multi-step process involving weighing the raw powder, dissolving it in bacteriostatic water, and passing it through a 0.22um hydrophilic sterile filter into a new sealed vial to ensure sterility. The user noted that purchasing the peptide in bulk was significantly more cost-effective (up to 10 times cheaper) than buying pre-made vials for a multi-month cycle.
