Stacking Semax and Selank: Finding the sweet spot for focus and anxiety

I've been experimenting with a nootropic stack for about 4 weeks now to help with my high-stress job. I'm currently running 200mcg of Semax intranasally in the morning and 250mcg of Selank in the early afternoon. The mental clarity from the Semax is incredible—I feel like I can lock into deep work for hours without the usual brain fog. However, I've noticed that if I take the Selank too late in the day, I have a bit of trouble winding down at night. Has anyone else experienced this? I'm considering dropping the afternoon Selank dose to 150mcg or moving it up to lunch time. Also, with the recent Category 1 reclassification, it's such a relief to get these from a reputable compounding pharmacy again rather than sourcing from overseas. Any advice on timing or potential synergy with other cognitive enhancers would be appreciated.
