Noopept is fat soluble and takes a while for full effects to ramp up, you get some effects right away but others later. People taking it on empty stomachs may not be enabling noopept's efficacy. I had this crash thing too at first, then noticed that a vendor I buy other bulk powders from carries noopept and says is best to take with a bit of food. So I do that now, have a little something to eat with the pept.
This guy ^^^ up here read my mind. I stopped taking noopept by itself (which I did to see what would happen). I have a 70% cacao dark chocolate powder with tiny bit of caffeine (30mg) and green tea blend - I take half a scoop of nasty chocolate with noopept, with the 100mg theanine, 1.5g taurine, 100mg inositol, fish oil, 1g creatine, 400mg ALCAR I take most mornings and no crash, no irratibility. 2g lecithin, about 300mg choline bitartrate. Perfect. Sometimes another choline dose a few hours later is needed, or chocolate.
Yeah I think there's definitely a synergy between cocoa and noopept. By itself, a strong cup of cocoa is mildly energizing, but on a day when I've taken noopept (even many hours before) it makes me wide awake for an hour or two, but without the unpleasant overstimulated feeling that I'd get from a big cup of coffee.
Also the effects of cocoa synergize with the CILTEP stack, but that one is easy to explain - theobromine is a PDE and of course its stimulating effects would be drastically enhanced by forskolin.
But the noopept synergy? I have no clue. It feels subjectively different from cocoa + forskolin, so I highly doubt it's a simple potentiation of theobromine. Anybody want to speculate about the mechanism?
