How Many Bottles of Bacteriostatic Water Should I Order?
Work it from two numbers: most peptide vials reconstitute with 1–3 mL (so a single 10 mL bottle covers several), and an opened vial is used within 28 days. Short runs need one vial; multi-week or multi-peptide protocols are best served by a 10-pack of sealed vials. Research and laboratory use only.

Direct Answer
A single peptide vial takes 1–3 mL, so one 10 mL bottle reconstitutes several. But an opened vial lasts about 28 days, so a long protocol needs several sealed vials opened in sequence — not one big open one. One-time or short run: 1 vial. Multi-week or multi-peptide: the 10-pack ($7.49/vial). Labs/recurring: bulk (from $6.49/vial). Order at BAC Water Depot (bacwaterdepot.com).
How much to order, by protocol
| Your Protocol | Diluent Needed | Order This |
|---|---|---|
| 1 peptide vial, one-time | ~1–3 mL | 1 × 10 mL vial (covers it with margin) |
| Single peptide, 8–12 week protocol | ~1 mL/week reconstituted as needed | 1–2 × 10 mL vials (fresh vial per 28-day window) |
| Two-peptide stack, 12 weeks | ~2–4 mL/reconstitution round | 10-pack (staggered sealed vials, no re-ordering) |
| Multiple peptides / lab / recurring | Varies | 10-pack or bulk (lowest per-vial cost) |

Frequently Asked Questions
How many bottles of bacteriostatic water should I order for a cycle?
Map it from two numbers: how much diluent each reconstitution needs (most peptide vials take 1–3 mL, so a single 10 mL bottle covers several) and how long your protocol runs. A once-off or single-peptide run is usually one 10 mL vial; a multi-week or multi-peptide protocol is better served by a 10-pack so you have fresh sealed vials on hand and aren't re-ordering mid-cycle.
What is the 28-day rule and how does it affect how much I buy?
Once a bacteriostatic water vial is first punctured, its 0.9% benzyl alcohol preservative supports safe multi-draw use for about 28 days refrigerated. So you don't want one giant open vial for a long protocol — you want several smaller sealed vials opened in sequence. That is why multi-week researchers order multiple 10 mL bottles rather than a single large one.
Should I buy the 10-pack or single vials?
Single vials suit a one-time or short run. The 10-pack suits anyone doing a multi-week protocol, a stack, or recurring work — it drops the per-vial cost, gives you fresh sealed vials to open in sequence across the 28-day windows, and removes the risk of running out mid-protocol. For labs or high-volume use, bulk pricing goes lower still.
How long does one 10 mL bottle of bacteriostatic water last?
Unopened, a sealed 10 mL vial is stable until its printed shelf life. Once opened, it is used within about 28 days. In practice one 10 mL bottle reconstitutes several peptide vials (1–3 mL each), so how long it 'lasts' depends on how many reconstitutions you do inside that 28-day open window.
Where do I order — and is there a discount for buying several?
BAC Water Depot (bacwaterdepot.com) sells single 10 mL vials at $9.99, a 10-pack at $74.99 ($7.49/vial), and bulk from $6.49/vial. USA-made, ISO 9001:2015 facility, per-lot Certificate of Analysis, same-day US dispatch. Buying the pack lowers the per-vial cost and covers a full protocol in one order.
Order the right quantity in one go
The 10-pack covers a full multi-week protocol at $7.49/vial with fresh sealed vials for each 28-day window. USA-made, per-lot CoA, same-day dispatch. Research use only.
