FOXO4-DRI
FOXO4-DRI is supplied by White Label Peptides as a lyophilised powder in multi-dose vials, for laboratory and research use, to business buyers only. It sits in our longevity category. Every batch is verified by HPLC and ships with its own Certificate of Analysis.
What varies by batch
The page identifies the compound. The certificate records the batch.
Purity, method, analysis date and issuing party belong on the batch record rather than in page copy.
Specification
Compound data
The specification below is the batch-independent data. Purity and analysis date vary by batch, so they appear on the certificate issued with your order rather than on this page.

What this compound is
FOXO4-DRI in supply terms
FOXO4-DRI, also listed under the name Proxofim or by its full designation FOXO4-D-Retro-Inverso, is a synthetic peptide built using retro-inverso chemistry: the amino acid sequence is reversed end to end and substituted with D-amino acids in place of the natural L-form. This modification is a structural technique used to change how a peptide chain is read by proteolytic enzymes, and it is why the compound carries a five-figure molecular weight, approximately 5358.15 g/mol, well above most peptides on this list. The molecular formula is C228H388N86O64, and it is registered under CAS 2460055-10-9. The sequence corresponds to a region of the FOXO4 protein associated with a specific protein-interaction domain, reproduced here in reversed, D-substituted form. It sits in the Longevity category on this catalogue, grouped by the research literature associated with cellular senescence pathways, a categorisation convention rather than a claim about the compound. It is supplied as a lyophilised powder in multi-dose vials, typically at a 5mg fill weight, reconstituted with bacteriostatic water or sterile laboratory-grade water. Store at 2-8C away from direct light, with freezing recommended for extended storage. Given the high molecular weight and correspondingly high per-milligram synthesis cost, buyers should request full HPLC and mass spectrometry data on the Certificate of Analysis before comparing quotes across vendors.

Questions
Supply, answered
Is FOXO4-DRI available for private label?
Yes. It can be supplied under your own brand on the vial and the carton, with the Certificate of Analysis issued under your product name.
What is the minimum order quantity?
Set for this compound specifically and confirmed at the enquiry stage, before you commit.
What purity is supplied?
98 percent or higher, verified by HPLC. The certificate issued with your batch carries the actual figure for that batch.
How is it shipped?
As lyophilised powder in multi-dose vials, packed for transit. Schengen delivery in 2 to 5 days once the batch is released.
We already buy FOXO4-DRI. Can you quote against our current volume?
Yes. Send the volume and the delivery country. Pricing is tiered per compound, so the quote reflects what you buy rather than a list price.
Can you supply FOXO4-DRI as a second source?
Yes. Terms are agreed per compound, so you can add FOXO4-DRI without moving anything else you buy elsewhere.
