sketchy BAC on amazon?

BAC water from retailers is fine - the bacteriostatic agent is standard and most major online sources maintain sterility.
 
Clarity is visual but doesn't confirm sterility. Pharma-grade without dyes is the actual bar - specific brand matters less than that.
 
BAC water from reputable online retailers is fine - the bacteriostatic spec is what matters, not the brand. 1mL recon on R50 is standard.
 
The courier route works well for Canada - the cross-border logistics beat dealing with sketchy unknown sources directly.
 
The main concern with Amazon BAC is sourcing verification - benzalkonium chloride concentration varies, and off-brand options don't always match the label. Hospira or Pfizer are the community-standard picks for a reason.
 
The 'who to trust now' question after a problematic batch is where independent testing becomes the more practical answer than reputation tracking - batch-level problems mean any reputation-based recommendation is still subject to the next batch turning out differently. Testing as the constant rather than source reputation is the more reliable framework.
