With a lack of reviews and a formulation containing some questionable ingredients that we could not find to benefit consumers, together with the possibility of the product being sub-standard, we placed this product in our # 4 ranking. Its redeeming features however, include the fact that they use all-natural ingredients plus, the price is cheap, if you are into taking a risk about the quality of the product.
Some people warn of the dangers of modafinil. There are anecdotal personal accounts online of people becoming dependent on this drug. Modafinil is the generic of the brand Provigil, a nootropic. Provigil is FDA-approved to stimulate wakefulness in people suffering from sleep disorders, such as narcolepsy and sleep apnea. Initially, Provigil was thought to have a benign, non-addiction-forming profile. As such, the Drug Enforcement Administration classifies Provigil as a Schedule IV drug, a category reserved for drugs with low abuse potential; however, recent research conducted by the National Institute on Drug Abuse (NIDA) has found that Provigil may in fact be addictive.
The principal metric would be mood, however defined. Zeo’s web interface & data export includes a field for Day Feel, which is a rating 1-5 of general mood & quality of day. I can record a similar metric at the end of each day. 1-5 might be a little crude even with a year of data, so a more sophisticated measure might be in order. The first mood study is paywalled so I’m not sure what they used, but Shiotsuki 2008 used State-Trait of Anxiety Inventory (STAI) and Profiles of Mood States Test (POMS). The full POMS sounds too long to use daily, but the Brief POMS might work. In the original 1987 paper A brief POMS measure of distress for cancer patients, patients answering this questionnaire had a mean total mean of 10.43 (standard deviation 8.87). Is this the best way to measure mood? I’ve asked Seth Roberts; he suggested using a 0-100 scale, but personally, there’s no way I can assess my mood on 0-100. My mood is sufficiently stable (to me) that 0-5 is asking a bit much, even.
Oxiracetam is one of the 3 most popular -racetams; less popular than piracetam but seems to be more popular than aniracetam. Prices have come down substantially since the early 2000s, and stand at around 1.2g/$ or roughly 50 cents a dose, which was low enough to experiment with; key question, does it stack with piracetam or is it redundant for me? (Oxiracetam can’t compete on price with my piracetam pile stockpile: the latter is now a sunk cost and hence free.)
Nootropics (/noʊ.əˈtrɒpɪks/ noh-ə-TROP-iks) (colloquial: smart drugs and cognitive enhancers) are drugs, supplements, and other substances that may improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals. While many substances are purported to improve cognition, research is at a preliminary stage as of 2018, and the effects of the majority of these agents are not fully determined.
