The next cheap proposition to test is that the 2ml dose is so large that the sedation/depressive effect of nicotine has begun to kick in. This is easy to test: take much less, like half a ml. I do so two or three times over the next day, and subjectively the feeling seems to be the same - which seems to support that proposition (although perhaps I’ve been placebo effecting myself this whole time, in which case the exact amount doesn’t matter). If this theory is true, my previous sleep results don’t show anything; one would expect nicotine-as-sedative to not hurt sleep or improve it. I skip the day (no cravings or addiction noticed), and take half a ml right before bed at 11:30; I fall asleep in 12 minutes and have a ZQ of ~105. The next few days I try putting one or two drops into the tea kettle, which seems to work as well (or poorly) as before. At that point, I was warned that there were some results that nicotine withdrawal can kick in with delays as long as a week, so I shouldn’t be confident that a few days off proved an absence of addiction; I immediately quit to see what the week would bring. 4 or 7 days in, I didn’t notice anything. I’m still using it, but I’m definitely a little nonplussed and disgruntled - I need some independent source of nicotine to compare with!
Traditional Chinese medicine also has a long, well-established relationship with nootropic herbs and plants. One of the most popular and well-known is ginkgo biloba, derived from the Chinese maidenhair tree, a relic of the ancient world. The maidenhair tree is the last living species of the division Ginkgophyta>. Some believe that the name ginkgo is a misspelling of the original Japanese gin kyo, meaning “silver apricot”. It’s seen as a symbol of longevity and vitality and is known to be effective at stimulating the growth of new neurons. Researchers have demonstrated that ginkgo flavonoids, the main constituents in ginkgo extract, provide potent anti-Alzheimer’s effects via antioxidant activity in the brains of mice and also stabilize and improve the cognitive performance of Alzheimer patients for 6 months to 1 year. Effective doses range from 120 to 240 mg one to four hours before performance, and for older adults, doses range from 40 to 120 mg three times a day.

This doesn’t fit the U-curve so well: while 60mg is substantially negative as one would extrapolate from 30mg being ~0, 48mg is actually better than 15mg. But we bought the estimates of 48mg/60mg at a steep price - we ignore the influence of magnesium which we know influences the data a great deal. And the higher doses were added towards the end, so may be influenced by the magnesium starting/stopping. Another fix for the missingness is to impute the missing data. In this case, we might argue that the placebo days of the magnesium experiment were identical to taking no magnesium at all and so we can classify each NA as a placebo day, and rerun the desired analysis:

Growing up, Joe was plagued with a myriad of health issues such as gut problems, autoimmune issues, chronic fatigue, brain fog, insomnia, and general inflammation. Both conventional and alternative doctors weren’t able to help him, so he decided to fix himself. With lots of health questions and few satisfying answers, Joe decided to read every research paper he could get his hands on and conduct thousands of experiments on his own body in order to fix his health issues. Joe started SelfHacked in late 2013 when he successfully fixed all of his issues, and now it gets millions of readers a month looking to educate themselves about how they can improve their health. Joe is now a thriving author, speaker, and serial entrepreneur, founding SelfDecode & LabTestAnalyzer.
"More and more of our young people are using these drugs to help them work. They've got their laptop, their iPhone, and their Adderall. This rising generation of workers and leaders may have a subtly different style of thinking and working, because they're using these drugs or because they learned to work using these drugs, so that even if you take the drugs away they'll still have a certain approach. I'm a little concerned that we could be raising a generation of very focused accountants."
Next generation medical imaging and genomic sequencing studies, including my own work, have helped reveal that some foods are neuro-protective, literally shielding the brain from harm and supporting cognitive fitness over the course of a lifetime. Conversely, other foods are harmful for the brain, slowing us down in general, making us feel sluggish and tired, while at the same time increasing our risk of dementia.

The exact moment when science morphed into science fiction was when so-called climate scientists (formerly known as weather forecasters) realised that some people could be conned into believing in man-made global warming and pumping fortunes into university departments to prove it. Now, they're all at it.Come back Arthur C Clarke. Your country needs you now.


I have been taking these supplements for almost three weeks now. What I have noticed is there is a marked difference in the decrease of my daily brain fog. This was huge for me! However, I gave the product 4 stars because of my concern about the high count of vitamin B6. I think this should have been addressed in a disclaimer for concerned consumers
In 2011, a story surfaced that struck fear into many: A woman was being treated for brain and memory disorders, when in reality she was just incredibly low in B12 stores. Turns out, this isn’t uncommon; many physicians don’t run routine blood tests for the nutrient, which is especially troublesome considering that our ability to absorb B12 is dramatically reduced with age. Over time, low vitamin B12 can do a number of your cognition.
Factor analysis. The strategy: read in the data, drop unnecessary data, impute missing variables (data is too heterogeneous and collected starting at varying intervals to be clean), estimate how many factors would fit best, factor analyze, pick the ones which look like they match best my ideas of what productive is, extract per-day estimates, and finally regress LLLT usage on the selected factors to look for increases.

The fact is, many of these compounds in small amounts and less frequent use can be relatively safe, but as you’re probably not surprised to hear, I’m not 100% convinced of the overall long-term safety or efficacy of most smart drugs used frequently or in moderate to high dosages for the reasons stated above. It is true that some are slightly less risky than others and are increasing in popularity among biohackers and medical professionals. They’re also becoming used with high frequency by students, athletes and e-gamers, three populations for which smart drug “doping control” is becoming more frequently banned and considered to be illegal use of performance-enhancing drugs. Yes, “brain doping” and “brain PED’s” (brain Performance Enhancing Drugs) are now a thing. But I’d consider carefully the use of smart drugs as daily go-to brain enhancing supplements, especially in light of the safer alternative you’re about to discover: the entire category of natural and synthetic nootropic compounds.
Methylphenidate – a benzylpiperidine that had cognitive effects (e.g., working memory, episodic memory, and inhibitory control, aspects of attention, and planning latency) in healthy people.[21][22][23] It also may improve task saliency and performance on tedious tasks.[25] At above optimal doses, methylphenidate had off–target effects that decreased learning.[26]
