How to verify this yourself
To verify before you buy: ask EZ Peptides for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

Cheapest Tesofensine, by price per mg
Vials come in different sizes, so the sticker price lies. This ranks every listing by what a milligram actually costs — with independent test purity where we have it.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg.
Understand this compound
What is Tesofensine?
In clinical trialsa.k.a. Tesomet (fixed-dose combination with metoprolol)A triple monoamine reuptake inhibitor studied in appetite and weight research.
Good to know: Phase 2 data showed elevated heart rate and blood pressure, which is why US development stalled; cardiovascular safety remains the central open question.
How does Tesofensine work?
A triple monoamine reuptake inhibitor; blocks reuptake of serotonin, norepinephrine, and dopamine to suppress appetite and modestly raise energy expenditure.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Tesofensine researched for?
Studied for obesity and weight loss, typically as a fixed-dose combination with the beta-blocker metoprolol (Tesomet) to offset cardiovascular effects.
- Weight & metabolicStudied in weight, appetite, blood-sugar, and fat-metabolism research.
- Cognitive & moodStudied in memory, focus, mood, and neuroprotection research.
How far has the research gone?
In clinical trials outside the US; Phase 3 ongoing for the Tesomet combination, but there is no active US Phase 3 program and it is not FDA-approved.
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.

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
UnknownNo independent third-party COA is advertised or on record for this listing.
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.
No third-party testing to cross-check
This listing doesn't advertise independent lab testing, and we don't hold an independent record for EZ Peptides's Tesofensine. Absence of a certificate isn't proof of anything — but there's nothing here to verify.
- Independent testing. No third-party COA advertised or on record.
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.
Research-use-only — not FDA-approved
Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.
