Bacteriostatic water by $/mL
Bacteriostatic waterSterile water with a small amount of benzyl alcohol, a preservative that slows bacterial growth; a common lab solvent. (and equivalent reconstitution solution) is the diluent used to reconstituteMixing a freeze-dried powder back into liquid so it can be measured and handled. pepmg gives no preparation or dosing guidance. lyophilized research peptides. It's a consumable priced per mL, not per mg — so we track it in its own category rather than forcing it into the $/mg index. Ranked by cost-per-mL alone; a vendor can't pay for the top spot.

Pharma-grade means a branded pharmaceutical vial — Hospira, Pfizer and similar — which is technically a prescription product. Generic means generic or research-labeled bacteriostatic water, the common vendor offering. This is a transparency label of what the product is, so you can compare like with like. It is not a quality, purity, or safety ranking: pepmg doesn't test these products and makes no claim that either is better or safer than the other.
"$/mL" is the vendor's list price ÷ total volume. Multi-vial packs and large vials are flagged bulk and never define the single-vial "cheapest". Where a pack's per-vial vs total volume isn't clear from the listing, we show n/a rather than guess.

concentration (mg/mL) and draw volume for laboratory handling.
All products listed are sold by third-party vendors for laboratory and research use only (RUO). pepmg sells nothing, ships nothing, and gives no medical, dosing, or human-use guidance. Listings are price-tracking data, not endorsements.
