Real listing aggregated from the vendor's public page. Buying happens on their site, never on VialGrade — outbound links stay off until the affiliate step is approved.
No independent test of PureRawz's Tirzepatide yet
- Tirzepatide generally tests around 99.8% purity across 29 independent certificates — but from other makers, so treat it as a benchmark, not proof of this seller's stock.
- We couldn't place this listing's price — its size isn't readable or the market's too thin — so there's no cheap-fake check here.
How to verify this yourself
To verify before you buy: ask PureRawz for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

What is Tirzepatide?
FDA-approved moleculea.k.a. Mounjaro, ZepboundThe dual GIP/GLP-1 agonist behind Mounjaro and Zepbound, studied heavily in weight and metabolic research.
Good to know: GI adverse events are the most common trial finding, and the source/purity of non-prescription 'research' tirzepatide is unverified.
How does Tirzepatide work?
A dual GIP/GLP-1 receptor agonist; activates both incretin receptors to enhance glucose-dependent insulin secretion, suppress glucagon, slow gastric emptying, and reduce appetite.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Tirzepatide researched for?
Studied for type-2 diabetes glycemic control and obesity/weight management, plus obstructive sleep apnea and other metabolic conditions.
- Weight & metabolicStudied in weight, appetite, blood-sugar, and fat-metabolism research.
How far has the research gone?
FDA-approved (for type-2 diabetes and obesity); approved as Mounjaro (2022) and Zepbound (2023), including a 2024 sleep apnea indication.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row answers a different question. Passing the identity test doesn’t mean it’s sterile or correctly dosed — we show each answer separately.
Identity — independent test
PartialThe vendor advertises third-party testing, but no independent record confirms it yet.
Measured purity (HPLC)
UnknownNo independent purity figure is on record for this listing.
Batch traceability
UnknownNo specific batch on this listing has been matched to an independent record.
Sterility & endotoxin
Not testedA purity COA does not measure sterility or endotoxins — no such test is on record.
Dose / fill accuracy
UnknownVialGrade does not independently measure vial fill or delivered dose.
These certificates are for Tirzepatide across every maker VialGrade tracks — not necessarily PureRawz’s own stock. This listing’s specific evidence is the matrix above.
Independent testing
Independent lab tests on record for Tirzepatide
Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.
How does this data get here?
Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.
Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.
We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.
What a certificate does & doesn’t prove
Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.
Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.

testing advertised, but not independently confirmed
This listing advertises testing, yet no independent record in our index references PureRawz for Tirzepatide. That doesn't prove the certificate is fake — but until it resolves at the lab, treat the testing claim as unbacked, not verified.
- Vendor claim. Advertises testing.
- Independent confirmation. No record found for PureRawz. Verify the certificate at the lab before trusting it.
- Compound-level evidence. We do hold 29 independent COAs for Tirzepatide (median 99.8%) — from other makers. Use it to judge this claim.
Cross-checks the vendor’s testing claim against independent lab records. Purity is read from the lab's certificate as issued — VialGrade doesn't re-run the assay or sample the vial. It reflects one lab's result for one submitted batch, not every vial. Never a statement that a product is safe, sterile, or correctly dosed.
This is a prescription drug in the US
This is the active drug in Mounjaro and Zepbound — an FDA-approved prescription medication. Buying a “research” version sidesteps the prescription requirement and the approved, quality-controlled supply chain. The FDA has warned about and acted against unapproved and compounded copies. Higher legal and safety exposure than an unapproved research peptide.
