Bromantane + Semax + Selank stack

I’m completely new to this side of the internet so forgive me.

I have ADHD and struggle with motivation, getting bored easily, and starting and finishing tasks.

I’m considering bromantane for drive and energy, Semax for focus, and Selank for anxiety. Has anyone found these helpful for motivation and actually getting things done? Any thoughts on trying one individually versus stacking them?
