Which vendors sell FOXO4-DRI with independent COA testing?

9 vendors in the Merit Verified directory have independent COA evidence on file for FOXO4-DRI — 20 COAs total. COA coverage and test dates are listed on the FOXO4-DRI page at https://meritverified.org/peptides/foxo4-dri.

How do I verify the quality of FOXO4-DRI from a vendor?

To verify FOXO4-DRI quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for FOXO4-DRI at https://meritverified.org/peptides/foxo4-dri so you can compare evidence across vendors before buying.

What is the regulatory status of FOXO4-DRI?

FOXO4-DRI is tracked in the Merit Verified registry. Regulatory status for research peptides in the US has been evolving — the FDA has reclassified a number of peptides out of the 503A compounding ingredient list since 2025. Merit Verified does not provide legal or regulatory advice; check official FDA sources or consult a licensed professional for the current status of FOXO4-DRI in your jurisdiction.

FOXO4-DRI

Also known as: FOXO4-D-Retro-Inverso

FOXO4-DRI is a D-retro-inverso peptide designed to disrupt the FOXO4-p53 interaction in senescent cells. It is studied as a senolytic agent that selectively induces apoptosis in senescent cells while sparing normal cells.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.
