I need to get this out to everyone as fast as possible. I'm a nurse and I've been reconstituting my peptides with bacteriostatic water purchased from Amazon (brand: "PureFlow BAC Water" sold by MedSupplyDirect). After my last injection I developed a significant injection site reaction — redness, swelling, warmth, pain radiating outward. Much worse than normal. I've done hundreds of SubQ injections on myself and patients. This was NOT normal. I had a friend at a hospital lab run an endotoxin test (LAL test) on the BAC water. It came back POSITIVE for bacterial endotoxins at a level WAY above acceptable limits for injectable solutions. LAL Test Results: - Sample: PureFlow BAC Water 30mL, Lot# PF-2026-0187 - Endotoxin level: 14.7 EU/mL - USP limit for injectable water: <0.25 EU/mL - Result: FAIL — 58x above acceptable limit This water is basically contaminated with bacterial cell wall fragments. Injecting this can cause fever, inflammation, and in serious cases, sepsis. If you have this product, STOP USING IT IMMEDIATELY.

Oh no. I literally have this exact product sitting on my desk right now. Same brand, bought it 2 weeks ago. I've used it to reconstitute 3 vials already. I've had unusual redness at my injection sites but I thought it was just a reaction to the peptide. Now I'm realizing it might be the water. What should I do? Should I go to urgent care?

Don't panic, but do monitor yourself. If you have: - Fever over 100.4F - Increasing redness/swelling at injection sites - Red streaks extending from injection sites - General malaise, chills, body aches - Any signs of systemic infection Go to urgent care or ER immediately and tell them you may have been exposed to endotoxin-contaminated injectable water. If your symptoms are just mild redness that resolves within 24-48 hours, you're likely okay but STOP using that water immediately. Throw it out. Get BAC water from a legitimate medical supply company (not Amazon).

Microbiologist here. 14.7 EU/mL is genuinely alarming. To put this in perspective: - USP limit for bacteriostatic water for injection: 0.25 EU/mL - What this sample contained: 14.7 EU/mL - That's approximately 58 times the acceptable limit Endotoxins are lipopolysaccharides from gram-negative bacterial cell walls. They're heat-stable, meaning even if the water was autoclaved, the endotoxins can persist. They cannot be filtered out with standard sterile filters. The fact that this product is sold on Amazon as "bacteriostatic water" for injection is horrifying. It likely was never produced in a proper cleanroom environment with depyrogenation steps. This is why pharmaceutical-grade BAC water is manufactured in ISO 5 cleanrooms with LAL testing on every batch. Random Amazon sellers are not doing this.

I've been warning people about Amazon BAC water for months. Here's the thing everyone needs to understand: Amazon does not verify that "bacteriostatic water" sellers are licensed pharmaceutical manufacturers. Anyone can: 1. Buy bulk purified water 2. Add benzyl alcohol 3. Put it in a vial 4. List it as "bacteriostatic water for injection" on Amazon 5. Start selling There's no FDA oversight on the Amazon marketplace for this. It's the wild west. Buy your BAC water from: - Licensed compounding pharmacies - Established medical supply companies (Hospira, etc.) - Your prescribing clinic NEVER Amazon, eBay, or random websites.
