Every Tesofensine listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 10 are here: the last 4 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

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. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
Understand this compound
What is Tesofensine?
In clinical trialsa.k.a. Tesomet (fixed-dose combination with metoprolol)An appetite-suppressing weight-loss pill that raises three brain chemicals at once. It worked in trials but stalled in the US over raised heart rate and blood pressure.
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?
The science
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.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row is a separate question with its own answer — one green row never vouches for the rest.
Identity
UnknownNo independent test on record for this listing.
Measured purity
UnknownNo independent purity measurement on record.
Batch traceability
UnknownNo batch on this listing matches an independent record.
Sterility
Not testedA purity certificate doesn't measure this — no such test on record.
Dose accuracy
UnknownNot something VialGrade measures — no test on record.
No third-party testing to cross-check
This listing doesn't advertise independent lab testing, and we don't hold an independent record for Modern Aminos'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. Read from the certificate, not re-measured by VialGrade. Purity is not a grade. Never a statement that a product is safe, sterile, or correctly dosed. What “grade” actually means

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.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
