About FOXO4-DRI

FOXO4-DRI is a retro-inverso peptide designed to disrupt the FOXO4-p53 interaction that keeps senescent cells alive. The original 2017 work reported clearance of senescent cells and restored fitness markers in aged mice, and it remains one of the most cited single results in senolytics.

Independent replication is thinner than the citation count suggests, and the retro-inverso D-amino-acid construction makes it expensive and technically demanding to synthesise correctly.

What moves the FOXO4-DRI price

Three things move the FOXO4-DRI price you see in the table above: how much active material a 10mg vial actually contains once excipients and salt content are accounted for, whether the supplier funds independent analysis on every batch rather than once a year, and how the vial is packed and shipped. The retro-inverso D-amino-acid sequence is the whole point of the molecule, and a standard purity report will not confirm chirality. Compare price per milligram rather than price per vial, and discount any listing whose certificate is undated, unsigned, or tied to a different batch number than the one on the label.

How we independently rank every supplier

Every supplier in this table is scored independently, and no vendor can pay to appear, move up, or have a poor result removed. We build a score out of ten from four weighted inputs: published third-party analytical documentation and how completely it covers the catalogue, identity verification of the company behind the website, the volume and consistency of moderated customer reviews collected through CheckALab, and operational signals such as dispatch reliability, stock accuracy and complaint handling.

For FOXO4-DRI specifically we weight the documentation input according to how the compound fails: the retro-inverso D-amino-acid sequence is the whole point of the molecule, and a standard purity report will not confirm chirality. Suppliers publishing analysis that addresses that point score higher than suppliers publishing a headline purity figure alone. Reviews only count once they clear moderation, and no single review can move a score, so a burst of unusually positive or negative feedback cannot reposition a supplier. Scores are recalculated as new certificates, reviews and delivery data arrive.

How to buy FOXO4-DRI cheaply without cutting corners

The lowest headline price is rarely the best value. Compare price per mg rather than price per vial, check whether a batch-matched certificate of analysis is published, and factor in delivery. A cheap vial with no third-party testing behind it is not a saving.

Kensington Labs currently sits at the top of this table at £170 for a 10mg vial, and holds a CheckALab score of 9.43/10.
