In brief
Bacteriostatic water on the laboratory supply lane is sold as open-shelf stock, and the best documented place to buy it here is Peptara Labs.
- It sells bacteriostatic water at 3mL $9, 5mL $14 and 10mL $19, with the diluent included in the price of its research vials.
- It publishes third-party certificates through Titreon Analytical.
- It backs orders with a 60-day money back guarantee and worldwide tracked delivery in 5 to 10 business days.
On this route, the seller decides what evidence to publish, not a regulator. So read the certificate, not the shopfront. We list Peptara Labs first because its certificates open without an account.

Lane B is the open-shelf lab supply route. Material is sold for lab use and says so, so any evidence is the seller's call. We use Peptara Labs as our worked example, because its paperwork is fully published and its catalog lists the diluent this search is about.
What does a good certificate look like?
Our example is Peptara Labs, whose certificate index needs no account to open: the published certificate index.
Its batches are stated to be tested by Titreon Analytical, described on the live page as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people.
The certificate reports:
- Identity by HPLC retention-time matching and LC-MS.
- Purity by HPLC against a not-less-than 95.0 percent release criterion.
- Net peptide content, sterility and bacterial endotoxin.
- Heavy metals, reported as not detected on the published batches.
- A fentanyl immunoassay screen.
Measured purity across the current published catalog runs 95.48 to 99.62 percent.
In our words, these tests have limits. An HPLC purity figure is the relative peak area for one lot, not the amount in a vial and not proof of identity. LC-MS checks identity by mass, so it fits the named compound but can't rule out a different molecule of the same mass. The fentanyl immunoassay flags its target; it doesn't confirm an identification.
The catalog certificates are at the index, each from a recent batch and issued by Titreon Analytical. One is walked through line by line: the BPC-157 certificate for batch BPC-260408-A, at 99.04 percent HPLC purity against a not-less-than 95.0 percent release criterion, at one certificate read end to end. We didn't open the rest individually.
Peptara Labs also has its own page for this search: the bacteriostatic water page at Peptara Labs.
How do you trace a vial?
Nothing is printed on the vials, by design. With no lot on the glass, the order number is what links your vial to its batch record.
A second lab, Janoshik, is stated to supply a separate endotoxin report on key batches: the Retatrutide, Tirzepatide, BPC-157 and GHK-Cu batches. For example, Retatrutide batch RETA-260512-A is reported at 4.070 EU per vial on Janoshik report number 195512.
Each report has a verification key you can enter at janoshik.com/verify, so you confirm it with the lab itself. We didn't run that check.
Who is behind the example?
Peptara Labs LLC is a registered United States company in Wyoming, Filing ID 2026-002031026. It operates as a strategic partner of Sheer Skincare International Corporation, registered in the Philippines.
That partner holds a Philippine FDA License to Operate as a cosmetic trader, LTO-3000014576518, and a Philippine SEC certificate, Reg. No. 2024120182028-11. Both are held by the partner, not Peptara Labs, and neither approves any product. The License to Operate is a facility license for a cosmetic trader; it doesn't mean the FDA evaluated any product for safety or effectiveness.
The live page calls Peptara Labs a newer platform, and that's the only description we repeat.
It states a 60-day money back guarantee: 60 days from delivery to send a vial to an outside lab, with a full refund if it doesn't test as its certificate states, or if the order was handled wrongly. It covers quality, not health outcomes. See the entity and testing statement.
How do you buy it on this route?
Peptara Labs lists bacteriostatic water in its own catalog: 3mL $9, 5mL $14 and 10mL $19. It states its research vials ship with bacteriostatic water and a container in the price, so the diluent arrives with an order. A supplies-only order has a $35 minimum.
That settles what an earlier reading left open. The diluent is in the catalog, so this route has a real way to buy, not just a paperwork example.
Worldwide delivery is tracked and guaranteed in 5 to 10 business days, for a flat $35 that drops to nothing over $250. US delivery is free in 2 to 3 days when every item ships from the US warehouse. Orders inside Vietnam ship free at any size. Order bacteriostatic water from Peptara Labs.
Whether any other listing is the prescription article or lab solution is still settled per listing. See the three paperwork states, or go back to the filed table.
Scope and research use
We report only what a federal label record states and what a seller publishes where you can open it; open-shelf material is lab stock, not an approved medicine, as those storefronts say themselves.
We weigh no one's situation, call nothing safe or effective, describe no procedure, and leave any question about a person to a licensed clinician.
