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 UK? and see all suppliers serving the UK.
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.
6 of the suppliers PepFinder tracks list Tesofensine and are based in the UK. The highest rated are Biolabs, biolabsuk.co.uk, Precision Peptides Shop. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews; stores shipping in from abroad are not included in the UK's prices; nobody pays to be included or to rank higher.
Orbitrex Peptides lists the lowest validated single-vial price per mg in the UK, £199.98/mg for a 500 mcg vial, as last checked on 11 Nov 2026. The cheapest listing is not automatically the best buy: weigh it against the store's PepFinder Score, its test certificates and its customer reviews, all shown on this page.
Suppliers on this page sell packs of 100 vials, compared per mg of the whole pack rather than against single vials. Other forms on sale (capsules) are different products and are not compared per mg with vials. Most research peptides are sold as freeze-dried powder in sealed vials.
Most research peptides are not controlled drugs in the UK, but selling or supplying an unlicensed medicine is an offence under the Human Medicines Regulations 2012; growth hormone and HCG are Class C controlled drugs. Our page on whether peptides are legal in the UK sets out the rules with a link to every source. This is general information, not legal advice.
Non-controlled medicines can be imported for your own use without an import licence, but Border Force can seize quantities above reasonable personal use, and controlled drugs such as growth hormone and HCG cannot be posted to you from overseas. 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, with stores that have nothing on sale after those that do. Prices, sizes and stock are as each site listed them when checked and may have changed.
