FAQ
- What does D-retro-inverso mean in FOXO4-DRI?
- The peptide is built from mirror-image (D-configuration) amino acids arranged in reverse sequence, increasing resistance to protease degradation compared with natural L-amino-acid peptides.
- How is FOXO4-DRI reconstituted for laboratory use?
- Dissolve the lyophilized powder in bacteriostatic water. Divide mg of peptide by mL of solvent to get mg/mL. A 10 mg vial with 2–3 mL of bacteriostatic water yields roughly 3.33–5 mg/mL.
- What is FOXO4-DRI's regulatory and sport status?
- It is not approved by any regulator for any use and is not a licensed product. Under the WADA Prohibited List it is classified as an S0 Non-Approved Substance, banned at all times both in and out of competition.
