At a glance · 25 Sept 2026
FOXO4-DRI is a designed peptide that breaks the grip of the FOXO4 protein on p53 inside senescent cells, pushing those cells to kill themselves. It became famous after a 2017 Cell paper in which it restored fur density, fitness and kidney function in fast-ageing and naturally old mice. Everything known about it comes from cells and animals: no human trial of FOXO4-DRI has been published or registered, and at least one study found that removing senescent cells this way made pulmonary hypertension worse. Read the full FOXO4-DRI 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 FOXO4-DRI is and what published studies have found, see our FOXO4-DRI 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.
13 of the suppliers PepFinder tracks list FOXO4-DRI and are based in or ship to the UK. The highest rated are XL Peptides, Simply Peptides, Pioneer Research Peptides. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews, with stores based in the UK placed before those shipping in from abroad; nobody pays to be included or to rank higher.
Listed prices in GBP run from £4.50/mg to £19.50/mg, median £7.70/mg, across 11 listings from 11 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 FOXO4-DRI in 10mg. 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.
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 FOXO4-DRI from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list FOXO4-DRI 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.
