clareza mental com uma só

Posted by 5483186271661421948 on Apr 25, 2016

no incio do uso meu cerebro parecia rejeitar dava uma sensaçao de esforço mental e parecia nao ajudar muito, mas depois a clareza mental e foco melhoram sim, mas nao tanto a memoria digamos que, de 0 a 5, clareza: 4, foco:3.8, memoria: 2.8 ....mas resumindo o produto é bom! poderia ter um com vinpocetine, bacopa e huperzina A ai seria o TOP!

These pills made me dumb!

Posted by CurbAnxiety on Mar 22, 2016

It's interesting to notice how differently these brain enhancers affect to different people. For me they were everything else than brain enhancers! I became totally dumb after taking these. The longer I took them, the more foggy my brain was and the less I could think clearly. It was almost impossible to work and that really affected also to the quality of my work, I'm ashamed of that! Moreover, an hour or two after taking these pills I became so tired that I had to take a nap, there was no other way out. I took the pills two weeks, one pill every morning and then I simply couldn't stand anymore. One note: as I follow ketogenic diet my brains mostly use ketones as energy, not glucose like normally. I wonder if this had anything to do with the bad results. Anyway, I'm happy with my brains and don't need this product, just wanted to try out if it would have had any positive effect. I'm happy for those people who have found help from this product, I'm just not one of them.
