PER4M Sleep is designed to help you wind down, switch off, and wake up feeling refreshed. Whether you’re pushing through intense training or just struggling to relax after long days, this formula brings together calming ingredients — including Ashwagandha, L-Theanine, and Magnesium to support relaxation and rest.
Each serving also includes L-Tryptophan, 5-HTP, and Zinc, which contributes to normal cognitive function and the regulation of hormone activity, ideal for supporting your evening routine without leaving you feeling groggy the next day. Tart cherry extract and Valerian root round out the formula, traditionally used to support natural sleep rhythms.
If your mind races at night or you just need better recovery between sessions, PER4M Sleep is the easy way to support better nights and stronger days. No grogginess, no nonsense, just quality rest when you need it most.
