I’ve used Lambda and Lab1 Research H2O (neither of which is currently offered now). I have Hospira now (from Injection Shop), but nice having options in case things change, which seems like the rule rather than the exception around here.
This data came from one of the "chicken embryo" sites that I can't post:
Several brands; Research H₂O, Quality Research, and Peptide Crafters met USP expectations for chemical parameters only (%BA and pH) but were not tested for sterility or endotoxins in the PTDS dataset.While their preservative strength and pH were compliant, their microbiological and pyrogen safety cannot be determined from available data.
Lambda Water passed %BA, pH, and sterility, but failed endotoxin testing (0.765 EU/mL, > USP ≤0.25 EU/mL)** This shows that even chemically acceptable formulations can still pose pyrogen risk.
In contrast, several brands showed critical failures:
Harmonify and Aqua Science (same manufacturer) had severely under-strength BA (0.087–0.23%), failed sterility, and had very high endotoxin levels (>5 EU/mL).
DNA Labs and Clear Choice showed unacceptable BA concentrations (too low or excessive).
Generic BAC0129 had near-spec BA (0.86%) but
extremely alkaline pH (8.84) outside USP limits.
Pure Labs contained
0.00% benzyl alcohol, meaning the product was chemically equivalent to sterile water for injection (SWFI) despite being sold as BAC water, indicating **mislabeling or formulation failure
Bottom line: go with Hospira
