Lyophilised (freeze-dried) research peptides have to be dissolved before laboratory use, and the solvent you choose matters as much as the peptide. If you need to buy bacteriostatic water, the easiest and cheapest way is to add it to your peptide order so everything arrives in one tracked parcel. This guide explains the three solvents we stock, when each is used, and what they cost.
What is bacteriostatic water?
Bacteriostatic water is purified water with benzyl alcohol added as a preservative. The benzyl alcohol slows the growth of bacteria, which is why it is the usual choice when a sealed vial will be opened and drawn from more than once. In the laboratory it is used to reconstitute (dissolve) freeze-dried research peptides.
Bacteriostatic water vs sterile water vs acetic acid water
| Solvent | What it is | Typical laboratory use |
|---|---|---|
| Bacteriostatic water | Water with benzyl alcohol preservative | Vials opened and drawn from more than once |
| Sterile water | Sterilised water with nothing added | Single use, or where a preservative is not wanted |
| Acetic acid water | Dilute acetic acid in water, typically 0.6% | Peptides that dissolve poorly in neutral water |
Because sterile water contains no preservative, a vial is normally used in one go once opened. Which solvent suits a given peptide depends on your protocol and the peptide’s properties; check the documentation for the compound you are working with.
Wholesale prices
Prices are per box of 10 vials in US dollars. The minimum order is 5 boxes per item, with lower prices at volume.
| Product | Vial size | 5–20 boxes | 20–50 boxes | 50+ boxes |
|---|---|---|---|---|
| Bacteriostatic water | 3ml | $6 | $5 | $5 |
| Bacteriostatic water | 10ml | $7 | $7 | $6 |
| Sterile water | 10ml | $7 | $7 | $6 |
| Acetic acid water | 3ml | $6 | $5 | $5 |
| Acetic acid water | 10ml | $7 | $7 | $6 |
That is as little as $0.50 to $0.70 per vial. Shipping is added on your invoice, so adding solvents to a peptide order costs you nothing extra to ship separately.
3ml or 10ml?
Choose the vial size that matches how much solvent each preparation uses. Smaller 3ml vials suit single preparations and reduce leftover solvent; 10ml vials suit work where one vial is drawn from several times, which is where the benzyl alcohol preservative in bacteriostatic water is most useful.
Order solvents with your peptides
Most customers add bacteriostatic water when they order peptides such as:
- BPC-157 and TB-500
- Semaglutide, tirzepatide and retatrutide
- GHK-Cu and the KLOW blend
See all reconstitution solvents, and keep your vials organised with our peptide storage cases.

Frequently asked questions
What is the difference between bacteriostatic water and sterile water?
Bacteriostatic water contains benzyl alcohol as a preservative; sterile water contains nothing added and is normally used once per vial.
How much does bacteriostatic water cost?
$6 per box of 10 x 3ml vials and $7 per box of 10 x 10ml vials for 5–20 boxes, at the time of writing.
When is acetic acid water used?
For peptides that dissolve poorly in neutral water, particularly some with many basic amino acids.
Can I buy just water without peptides?
Yes, with the usual minimum of 5 boxes per item.
