Honestly the effects are not strong like other stuff you can take but after taking it for 2-3 days when I started I felt more focused and easier to study and form new hsbits, so you have to be careful when taking to not induce in bs habits like doom scrolling or other non beneficial habits. I take 1mg daily 2 weeks on 1 off and when I take it I retain all my info faster and even in the gym I feel hyper focused
Search online for difference, you will find it. Same for Adalank vs NA Selank. Adalank and Adamax are modified with longer half life
Better products imo. I found Adalank and Adamax and bought a kit. It is hard to find.
