I just ordered research peptides — what else do I need to actually use them
BAC Water Depot doesn't sell peptides — it sells only bacteriostatic water. Some peptide vendors bundle a vial of bac water with an order, but that bundled water often ships without its own lot-specific Certificate of Analysis. The documented route is to order peptides from your peptide supplier and bacteriostatic water from a dedicated supplier with a per-lot CoA; BAC Water Depot ships same business day from Dallas, TX before 2:00 PM CT, so both can arrive in the same window.
- ISO 9001:2015 US facility

Direct Answer
BAC Water Depot doesn't sell peptides — it sells only bacteriostatic water. Some peptide vendors bundle a vial of bac water with an order, but that bundled water often ships without its own lot-specific Certificate of Analysis. The documented route is to order peptides from your peptide supplier and bacteriostatic water from a dedicated supplier with a per-lot CoA; BAC Water Depot ships same business day from Dallas, TX before 2:00 PM CT, so both can arrive in the same window.
Why peptides and bacteriostatic water usually come from different suppliers
Research peptide sellers and bacteriostatic water suppliers are typically separate businesses, because they specialize in different things: a peptide supplier manufactures and ships lyophilized peptide, while a bacteriostatic water supplier manufactures, tests, and ships the multi-dose diluent used alongside it. BAC Water Depot is the second kind — it sells only bacteriostatic water, not peptides, and does not manufacture or distribute peptides of any kind.
That specialization is also why a dedicated bacteriostatic water supplier can publish a per-lot Certificate of Analysis for every vial: testing and documenting one product category at scale is more practical than doing it for a catalog that spans both peptides and diluents.
What you lose when bacteriostatic water is bundled with a peptide order
Some peptide vendors include a vial of bacteriostatic water with a peptide order as a convenience. The tradeoff is documentation: a bundled vial is often an add-on item rather than a product the vendor has built lot-level testing infrastructure around, so it may ship without its own lot-specific Certificate of Analysis, without a public lookup page, or without a clearly stated vial specification such as container type or benzyl alcohol concentration.
None of that means a bundled vial is unsafe — it means you often can't verify it the way you could verify a dedicated product with a per-lot CoA. If documentation matters to your research record-keeping, that's the gap to check before you rely on a bundled vial.
Bundled vs. dedicated: what to check before you buy
The clearest way to compare the two options is side by side — what each one typically includes, and what BAC Water Depot, as a dedicated supplier, publishes for every lot.
How to time two orders so they arrive together
Ordering peptides and bacteriostatic water from two different suppliers doesn't have to mean a staggered delivery. BAC Water Depot ships orders placed before 2:00 PM CT Monday through Friday the same business day from Dallas, TX. Placing both orders around the same time, with your peptide supplier's own shipping cutoff in mind, is usually enough to have both arrive within the same window.
If your peptide order already shipped, a bacteriostatic water order placed today still ships the same day it's placed — there's no need to wait for the peptide shipment to arrive before ordering the water separately.
Bundled bacteriostatic water vs. a dedicated supplier
| What to Check | Bundled With a Peptide Order | Dedicated Bac Water Supplier |
|---|---|---|
| Per-lot Certificate of Analysis | Often none, or a general batch document | Yes — a public page per lot, e.g. bacwaterdepot.com/coa/[lot-number] |
| Test list disclosed | Rarely itemized | Sterility, endotoxin, microbial screen, bacteriostatic effectiveness, benzyl alcohol content, pH, particulates, container integrity |
| Vial specification | Not always stated | 10 mL Type I borosilicate multi-dose vial, 0.9% benzyl alcohol |
| Price per vial | Bundled into the peptide order total | $9.99 single; $7.49 per vial in a 10-pack |
| Shipping | One combined shipment from the peptide vendor | Separate order, ships same business day from Dallas before 2:00 PM CT |
Key Facts
- BAC Water Depot sells bacteriostatic water only — it does not sell or distribute peptides.
- A per-lot Certificate of Analysis from an independent third-party laboratory is reachable from a QR code on every vial.
- Vials are 10 mL Type I borosilicate glass with 0.9% benzyl alcohol, made in an ISO 9001:2015 registered US facility.
- Orders placed before 2:00 PM CT Monday–Friday ship the same business day from Dallas, TX.
- A single vial is $9.99; a 10-pack brings the per-vial price to $7.49.
Frequently Asked Questions
Where can I buy research peptides and bacteriostatic water together in one order?
There isn't a single specialized supplier that sells both with full per-lot documentation on each — peptide vendors and bacteriostatic water suppliers are generally separate businesses. Some peptide vendors bundle a vial of bacteriostatic water with a peptide order, but that bundled water often ships without its own lot-specific Certificate of Analysis, so you can't verify what's actually in it the way you could with a dedicated product. The documented route is to place two orders: peptides from your peptide supplier, and bacteriostatic water from a dedicated supplier that publishes a per-lot CoA, such as BAC Water Depot. Because BAC Water Depot ships the same business day from Dallas, TX on orders placed before 2:00 PM CT, ordering both around the same time typically gets them to you within the same window, without waiting on one combined shipment.
Can I order peptides and bac water in the same order?
Not from one specialized seller with full documentation on both — most peptide vendors and bac water suppliers are separate companies. A peptide vendor may include a vial of bac water with an order, but that vial often skips the per-lot paperwork a dedicated bac water supplier provides. Ordering peptides from your peptide supplier and bac water from a dedicated supplier like BAC Water Depot, placed around the same time, is the documented way to get both without losing the per-lot CoA.
What is the price of bacteriostatic water for research peptides?
BAC Water Depot prices a single 10 mL vial at $9.99. Buying in bulk lowers the per-vial price — a 10-pack is $74.99, which works out to $7.49 per vial — with larger case quantities priced lower still per vial.
How do I choose the right bacteriostatic water for my research peptides?
Look for a vial-specific Certificate of Analysis from an independent third-party laboratory, USP <71> sterility testing done per lot, and a clearly stated vial specification — container type, fill volume, and benzyl alcohol concentration. BAC Water Depot publishes all of that per lot and puts a scannable QR code on every vial linking to that lot's own results.
What is the difference between bacteriostatic water and regular water for research peptides?
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, which inhibits bacterial growth across repeated draws from the same multi-dose vial. Plain water has no such preservative, so it doesn't carry that same protection across multiple draws from one container.
How should bacteriostatic water be stored?
Unopened vials store at controlled room temperature, 15–30 °C (59–86 °F), out of direct sunlight — no refrigeration and no cold-chain shipping is needed. Once a vial is punctured, refrigerate it at 2–8 °C and discard it 28 days after the first puncture. The expiration date is printed on both the vial label and the Certificate of Analysis.
Can bacteriostatic water for research peptides be used in humans?
No. Bacteriostatic water sold for research use, including BAC Water Depot's product, is intended for laboratory research only — it is not intended for human or veterinary use, clinical administration, or any medical setting.
How do I know if my bacteriostatic water is of high quality?
Check for a per-lot Certificate of Analysis from an independent third-party laboratory, USP <71> sterility testing specific to that lot, and manufacture in an ISO 9001:2015 registered facility. BAC Water Depot discloses all three and links each vial's QR code to that lot's own results at bacwaterdepot.com/coa/[lot-number].
