I got my Adamax, selank and celebrolysin order a week ago. I been using them intranasal and Adamax ceiling effect is longer but not instant like Semax. Yes it last around 12 hours. I was expecting semax instant kick with additional half life. Adamax needs momentum to reach ceiling effect. These past couple of days I used semax, adamax and selank together to start my morning. Semax for the quick start, adamax to go long and selank to tame them with all the compiled focus. lol Guys, I am still on them and its been past 24 hours, it is tapering very slowly. Must have been the second round of selank this evening. Today beside my charged latte I also used motsc 1.5mg, NAD 10mg, SS-31 1mg, essential amino acid, test booster, zinc, methyl B complex, essential vit and minerals. Yesterday I did coQ10, methelyne blue, magnesium complex, zinc and vit and minerals. Maybe they added to the effect. I been taking it easy with celebrolysin. I may need to water it down a little more 'cause it is a bit strong. At the moment celebro' needs to taper down to get to the sweet spot. I can only describe it as vivid clarity. No flow state yet. lol
