For short-term use (days to weeks), refrigeration at 4°C (39°F) is acceptable.
Lyophilized peptides are typically stable at room temperature for several weeks, making it suitable for moderate-term storage.

Centered X Capsules is a PH Bio Labs research formula (Dihexa 2mg, Selank 0.3mg, Semax 0.3mg, and NAD+ 100mg). It is supplied for laboratory and in vitro investigation only. It is not for human or veterinary use.

This blend may support research into cognitive enhancement and neuroprotective mechanisms. Specifically, Dihexa has been studied for its potential to influence synaptic growth. Similarly, Selank and Semax have been studied for their potential roles in modulating neuropeptide signaling and stress responses. In addition, NAD+ may assist studies focused on cellular metabolism, energy production, and oxidative balance.
