What is the downside of nootropics?

Four currencies for one category: the stimulant invoice and the stack invoice, which most lifters are already paying

What is the downside of nootropics is a question usually answered with a side-effects list, and a side-effects list is the smallest of the four bills the category sends, because nootropics charge their users in four different currencies and the lifter who checks only the one column pays the other three without noticing. The first is the stimulant invoice, and most lifters pay it daily without calling it a nootropic cost, because the one nootropic that works for everyone is caffeine and caffeine charges for its work. It charges sleep: with a half-life of five to six hours, a 200mg dose at three in the afternoon leaves around 70mg in the blood at eleven, enough to lengthen the time to fall asleep and shallow the first part of the night in people who swear it does not affect them, which the sleep laboratories have measured and the sleepers have not noticed. It charges anxiety and arousal: self-reported anxiety, heart rate and restlessness rise with the milligrams in a dose-dependent way, more steeply in sensitive people and in anyone already anxious, so that the pre-workout scoop that makes one lifter sharp makes another jittery and short-tempered for the afternoon. It charges tolerance: regular use blunts some of caffeine's effects, so the lift that a cup produced in January needs two cups by June and the habit escalates to stand still. And it charges withdrawal: abrupt cessation produces a recognised syndrome of headache, fatigue and low mood that peaks at one to two days and clears within about a week, which is why the first day of a deload or a holiday without coffee feels like illness. None of this makes caffeine a bad nootropic; it makes it one with an invoice, read in milligrams and hours. The second is the stack invoice, charged by the multi-ingredient focus, brain and nootropic products that make up most of the shelf. A proprietary blend charges hidden doses, a single total in milligrams for a dozen named ingredients with no figure for any of them, so that the buyer cannot know whether the B vitamins reach the register threshold, whether the botanical is at a trial dose or a token one, or whether the lion's mane inside is a stated extract or a powder. It charges an unreadable caffeine figure, since a blend's caffeine from guarana, green tea and coffee bean is often undeclared in milligrams and cannot be added to the day's census, which is how a stack pushes a lifter past 400mg without a decision. It charges combination risk: a dozen ingredients in one capsule is a combination no trial has tested and no pharmacist has assessed, and the interactions that matter for a lifter on medication are multiplied by the count. And it charges the inability to stop one thing at a time, so that a buyer who feels wrong on a stack cannot tell which ingredient to drop and drops the lot or none.

The grey-market invoice, the opportunity invoice, and which bills a food-law supplement like lion's mane actually sends

The third is the grey-market invoice, and it is the one that costs health rather than sleep or money, charged to the lifter who leaves the shop shelf for the websites that sell the compounds the forums discuss. It charges unknown contents: products from unregulated online sellers are mislabelled, under-dosed, over-dosed or adulterated at rates the medicines regulator warns about, so that a buyer does not know what they have taken, in what dose, with what else. It charges the law: a prescription-only medicine bought without a prescription is unlawfully supplied and its import is the buyer's own exposure, and a compound caught by the Psychoactive Substances Act is unlawful to supply or import whatever a website says. It charges dependence in the specific case of phenibut, a compound sold as a calming nootropic for which case series document physical dependence and a withdrawal syndrome severe enough to need medical management, which no food-law supplement has ever produced. And for the unprescribed stimulants, methylphenidate and modafinil bought online, it charges the cardiovascular and psychiatric effects that a prescriber would have weighed and nobody did. The fourth is the opportunity invoice, and it is the one every nootropic sends, the harmless ones included. Every pound spent on the shelf and every hour of attention spent reading it is taken from the three cognitive enhancers with the evidence, sleep, where restriction impairs attention and learning dose-dependently and extension restores them; training, which improves executive function and memory and which a lifter is already doing; and a blood test, which finds the iron, B12 or thyroid problem that a nootropic was bought to paper over. A lifter who buys a stack to fix the focus that six-hour nights destroyed has paid the fourth invoice in full and received nothing, and the stack's marketing is designed to send exactly that bill. Which invoices a food-law supplement like lion's mane actually sends is now easy to state. The stimulant invoice: none, since it is caffeine free. The stack invoice: none for a single-species stated extract, and all of it for a blend. The grey-market invoice: none, since it is a culinary mushroom sold lawfully as a food. The opportunity invoice: yes, in full, since 13p a day and the attention to buy it are spent on a sixteen-week trial in thirty older adults and a young-adult pilot, with mild stomach complaints and rare allergy the only physical entries in the trial and case report record, and the exclusions, pregnancy, breastfeeding, fungal allergy and under-18s, and the three pharmacist mentions standing as they do for any supplement. The downside of nootropics, then, is mostly not the one in the side-effects column: it is lost sleep and tolerance from the stimulant, hidden doses from the stack, real harm from the grey market, and, for the harmless majority of the shelf, money and attention diverted from the things that work. A food-law supplement whose invoice is mostly the fourth kind: a stated 5:1 fruiting body extract labelled 1500mg mushroom equivalent, 120 capsules for £15.49, 120 days at 13p, vegan shell, UK made under GMP and BRC, independently lab tested, caffeine free, bought after the sleep, the training and the blood test and not instead of them.
