Buy bacteriostatic water in Canada
Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol that prevents bacterial growth after the vial is opened. This 10 mL vial is the mid-size option in our lineup, sitting between the 2 mL single-use vial and the 30 mL multi-use bottle. You buy bacteriostatic water in Canada when you need a reliable diluent for reconstituting lyophilized peptides, HGH, or other injectable compounds.
Who needs bacteriostatic water
You need it if you use any of these:
- Peptides like DSIP, ipamorelin, BPC-157, or cagrilintide
- Growth hormone like somatropin
- Weight loss peptides like tirzepatide or retatrutide
- Any lyophilized (freeze-dried) vial that requires reconstitution before injection
NOTE: If you only reconstitute one vial and use it within hours, sterile water works. But if you draw from the same vial across multiple days or weeks, bacteriostatic water is mandatory because the benzyl alcohol preservative prevents contamination between draws.
What makes it different from sterile water
Plain sterile water has no preservative. Once you puncture the vial with a needle, bacteria can enter and multiply. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth for up to 28 days after opening. That multi-use capability is why every peptide protocol specifies bacteriostatic water, not sterile water.
| Feature | Bacteriostatic water | Sterile water |
|---|---|---|
| Preservative | 0.9% benzyl alcohol | None |
| Multi-use safe | Yes (up to 28 days) | No (single use only) |
| Best for | Peptides, HGH, multi-draw vials | Immediate single-use reconstitution |
Which size do you need
| Vial size | Best for | Link |
|---|---|---|
| 2 mL | Single vial reconstitution, travel, trial runs | 2 mL vial |
| 10 mL | 2-4 peptide vials, standard HGH reconstitution | This product |
| 30 mL | Long peptide phases, multiple compounds, best per-mL value | 30 mL bottle |
How to reconstitute a peptide vial
- Wipe the bac water vial stopper and the peptide vial stopper with an alcohol swab.
- Draw the desired volume of bacteriostatic water into an insulin syringe (typically 1.0-2.0 mL depending on the peptide and your preferred concentration).
- Insert the needle into the peptide vial and inject slowly down the glass wall. Do not blast the water directly onto the powder.
- Gently swirl the vial until the powder is fully dissolved. Never shake.
- Store the reconstituted vial in the refrigerator (2-8 degrees C).
- Use within 28 days of reconstitution.
Storage
Unopened: Room temperature, away from direct sunlight.
After first puncture: Room temperature is acceptable, but refrigeration extends usable life.
Reconstituted peptide vials (mixed with bac water): Always refrigerate (2-8 degrees C), use within 28 days.
What bacteriostatic water is not
It is not injectable on its own. It is a diluent for reconstituting compounds, not a standalone product. It is not saline (no sodium chloride). And it is not a substitute for proper sterile technique. Always use alcohol swabs, clean needles, and a clean workspace.

Bacteriostatic Water FAQ
How much bacteriostatic water do I need per peptide vial?
Most peptide reconstitution calls for 1.0-2.0 mL per vial, depending on the compound and your preferred concentration. A 10 mL vial covers 5-10 peptide reconstitutions at standard volumes, making it the practical choice for multi-vial peptide phases.
Can I use regular water instead?
Only if you plan to use the entire reconstituted vial in a single session. For multi-day or multi-week peptide protocols (which is almost always the case), you need the benzyl alcohol preservative in bacteriostatic water to prevent bacterial growth between draws.
How long does reconstituted peptide last?
When reconstituted with bacteriostatic water and stored in the fridge (2-8 degrees C), most peptides remain stable for up to 28 days. Some compounds degrade faster. Check the specific peptide product page for storage guidelines.
Does the 10 mL vial have a rubber stopper?
Yes. The rubber stopper allows multiple needle punctures for drawing water across several reconstitutions. This is the key advantage over amp-format sterile water, which is single-use once opened.
Is USP grade important?
USP (United States Pharmacopeia) means the product meets published standards for purity, quality, and consistency. For anything you inject, USP grade is the minimum standard you should accept. This vial meets that standard.
Should I buy the 10 mL or 30 mL?
If you are reconstituting 2-4 peptide vials, the 10 mL is the right size. If you are running a longer phase with multiple compounds (HGH + peptides), the 30 mL bottle offers better per-mL value and fewer reorders. The 2 mL vial is for single-vial needs or travel.
Why buy bacteriostatic water in Canada at Roids101?
We stock USP-grade product, ship domestically with same-day dispatch, and carry everything else you need for peptide protocols: the peptides themselves, insulin syringes, alcohol swabs, and drawing needles. Build your full reconstitution kit in one order.
