Bacteriostatic water is a sterile solution containing 0.9% benzyl alcohol, which acts as a preservative to inhibit bacterial growth
It is normal and not a sign of contamination
Peptides with sequences rich in hydrophobic residues, or those with a high proportion of basic amino acids (lysine, arginine, histidine) that require protonation for charge-mediated aqueous solubilisation, typically reconstitute cleanly and completely in 0.1% acetic acid water whereas the same peptides may form aggregates, gels, or turbid suspensions when reconstitution with neutral sterile water or bacteriostatic water is attempted first
For example, if you look on Clinicaltrials.gov, there are only two studies that even mention BPC-157, says Cushman
They work -- but they work by suppressing inflammation, not by repairing tissue
