It is a clinical decision that depends on what you are trying to treat, how your body processes the peptide, and whether the product you are using is actually safe for human administration
The reversed sequence combined with D-amino acids produces a mirror-image topology that is functionally equivalent to the native FOXO4 binding domain for protein-protein interaction disruption, a design strategy validated in the landmark 2017 Cell study

That's why peptide therapies, I believe, are growing in popularity
632 Di-Huang-Yin-Zi effectively decreases ROS and MDA levels in prefrontal cortex, increases the expression of ferroptosis-related markers GPX4 and SLC7A11 and, and decreases iron deposition, thereby improving depressive symptoms and synaptic ultrastructure of cortical regions in post-stroke depressed (PSD) rats, suggesting that Di-Huang-Yin-Zi can reduce the symptoms and enhance function in PSD rats by inhibiting ferroptosis through SLC7A11/GPX4 pathway
