Healthcare worker here. I want to address the BAC water specifically since that's the most critical supply.
The key spec to verify is the benzyl alcohol concentration: 0.9%. This is the FDA-standard concentration for bacteriostatic water. Too low and it won't adequately prevent bacterial growth. Too high and it could cause tissue irritation at injection sites.
GGPeps BAC water at 0.9% is correct. I've compared it to pharmaceutical-grade BAC water (Hospira brand) side by side and they look identical. Can't vouch for sterility without lab testing, but the proper benzyl alcohol concentration is a good sign of legitimate manufacturing.
One tip: NEVER use regular sterile water (without benzyl alcohol) for peptides you'll keep more than 24 hours. BAC water is essential for multi-dose vials. The preservative prevents bacterial growth in the vial between uses. 💉
