Tesofensine is a small-molecule drug, not a peptide, that blocks the reuptake of noradrenaline, dopamine and serotonin in the brain. It was developed for Parkinson’s and Alzheimer’s disease, failed there, and was redirected to obesity after trial participants lost weight; a 2008 phase 2 trial reported about 10% weight loss over 24 weeks, but the trial was later the subject of an expression of concern and an author correction about under-reported adverse effects. As of September 2026 it is not an approved medicine anywhere we could confirm, it is prohibited in competition by WADA, and it is sold online as a supplement and as a “research” product, neither of which is a licensed medicine. Read the full Tesofensine guide, with the published research and references.

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.
For what Tesofensine is and what published studies have found, see our Tesofensine guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in the US? and see all suppliers serving the US.
How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.
Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.
11 of the suppliers PepFinder tracks list Tesofensine and are based in or ship to the US. The highest rated are BioPep, Cenexa Labs, RCHQ. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews, with stores based in the US placed before those shipping in from abroad; nobody pays to be included or to rank higher.
Listed prices in USD run from US$109.98/mg to US$398.00/mg, median US$271.69/mg, across 10 listings from 8 suppliers. Compare price per mg rather than price per vial, and only within one currency; a price far below the rest is more often a warning than a bargain.
Suppliers on this page list Tesofensine in 218.6 mcg, 250mcg, 500mcg, 500 mcg, 1 bottle, 2 bottles. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.
The FDA treats research peptides sold for human use as unapproved new drugs and has said in 2026 warning letters that research-use-only labels do not change that. Our page on whether peptides are legal in the US sets out the rules with a link to every source. This is general information, not legal advice.
The FDA says it is illegal in most circumstances for individuals to import drugs for personal use, and shipments it considers unapproved drugs can be refused entry. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.
Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for Tesofensine from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list Tesofensine on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
