A lack of motivation to complete tasks can block your ability to get ahead in life. In this article, we explain how motivation works in the brain, what could be the problem behind your motivational deficits, and which drugs to use to improve them.
What is Motivation?
If you’re looking to improve motivation, you should look into things that increase dopamine.
The dopamine pathway is strongly implicated in motivational processes. Motivation refers to an internal drive to engage in a specific behavior, typically in pursuit of a reward or reinforcer .
Injecting dopamine blockers slows motivated reward-seeking behaviors .
Dopamine has also been highly accepted in reinforcement learning, a motivated learning process based on the incentive of reward .
Dopamine provides motivation due to an increased feeling of reward when tasks are completed .
How Humans Get Motivated
Cost-Benefit Analysis of Motivation Theory
This theory says every decision has a cost and value that must be calculated, increasing your motivation towards tasks deemed more important to yourself .
The costs associated with motivated actions may include:
- Physical Effort
- Mental Effort
- Loss of potential opportunities
- Danger (perceived possibility of pain or death)
The benefits associated with motivated actions may include:
- Fulfilling physical and psychological needs
- Obtaining secondary reinforcement (to physical and mental needs)
- Escaping from harm
Motivation increases when the benefit of a task outweighs the costs.
Another theory of motivation (social-cognitive) is that if you think you are capable of getting something done, you’ll be more motivated to do it .
Diseases Linked to Low Motivation
Having a healthy brain will help with motivation. By protecting nerve cells, increasing blood flow, and preventing diseases, you can keep your motivation high .
Apathy and disease-induced deficits in motivation are displayed in patients with disorders like:
- Anxiety disorders
- Bipolar disorder
- Alzheimer’s disease
- Parkinson’s disease
- Huntington’s disease
8 Natural Substances to Improve Motivation
- Increases available dopamine receptors, which helps increase dopamine levels .
- Increases serotonin and its receptors, vital to mood and outlook .
- Entrains the circadian rhythm and helps with sleep .
- Raises endorphin levels, which increases motivation .
- Increases productivity .
Flavonoids are a class of plants and fungal secondary by-products. They can be found in many foods in a healthy diet, as well as supplemented with extracts.
There are thousands of different flavonoid extracts with varying effects, some having the potential to increase motivation.
Blueberry flavonoids had an acute improvement of mood in children and young adults .
- Increase dopamine by inhibiting the MAO enzymes .
- In a rat model of Parkinson’s, some flavonoids (polymethoxylated flavones, procyanidins, and isoflavones) protected dopamine neurons .
- Increase brain blood flow .
- Prevent the death of neurons .
- Increase synaptic plasticity (the strengthening or weakening of synapses over time) .
- May delay the progression of brain diseases .
Caffeine is a brain stimulant and the world’s most widely consumed drug.
Moderate doses of caffeine increased sexual motivation in female rats .
Caffeine improved motivation and cognitive performance in complex tasks (bees) .
- Blocks adenosine receptors (A1R, A2aR, A2bR, and A3R), leading to an indirect increase of dopamine [16, 17].
Pregnenolone is a hormone that can increase reward-related processes and improve mood and motivation .
Rats’ motivational incentive increased after pregnenolone injections. They more easily found a reward in a new location .
Pregnenolone reduced motivation deficits induced in mice (by a competitive NMDA activator) in active avoidance and lever-press learning tasks .
- Increases steroid hormones such as allopregnanolone, which increases brain cell production, protects the brain and reduces cell death and inflammation.
- Increases dopamine release and response .
It is an addictive drug. Non-smoking ways of consumption including snus, patches, gum/lozenges, vaporizing (reduces the danger of smoke exposure but does not remove the risk of addiction).
Nicotine can induce :
- Reinforcement of reward
- Enhancement of performance
Nicotine is currently under investigation for the treatment of :
- Alzheimer’s disease
- Parkinson’s disease
Nicotine significantly improved motivation-driven behavior in rats .
- Increases dopamine in the brain .
N-Acetyl-L-Tyrosine is a version of tyrosine thought to have superior bioavailability compared to L-Tyrosine alone.
Users report that N-Acetyl-L-Tyrosine gives them a better mood lift, more stimulation, and increased motivation over L-Tyrosine.
In contrary to user reports, one older study in mice found that N-Acetyl-L-Tyrosine was the weakest of the tyrosine prodrugs .
- Converts to dopamine through L-dopa
In a study of 120 adults (prospective cohort), 80% of patients reported “very good, or good” improvements in :
- Decreased Motivation
- Daytime sleepiness
- Decreased Libido
- Sleep disturbances
- Cognitive impairments (concentration, forgetfulness, memory, stress, irritability)
On the contrary, other studies (double-blind randomized controlled trial) failed to find significant differences between the effects of rhodiola and placebos .
- Rhodiola inhibited MAOI-A and B in cell studies, which would lead to an increase in dopamine .
- Stimulates the brain .
- Prevents oxidative damage .
Tyrosine is the precursor to L-dopa, which converts to dopamine.
- Converts L-dopa to dopamine through the tyrosine hydroxylase enzyme 
13 Synthetic Drugs That Increase Motivation
Caution: Selfhacked does not support or have a stance on taking these or any drugs. Do not take this post as promoting the use of these medications. It is for informational purposes alone. These are popular drugs, and people should know their uses, the evidence behind them, and their drawbacks. You should not take drugs without a doctor’s recommendation.
Joe does not use any drugs from this list because he likes to increase dopamine naturally.
The list was created from a nootropics survey and we are just providing the research behind why users might experience more motivation on some of these drugs. We are not advocating their use.
Amphetamine increased the user’s motivation to pick tasks with a higher workload with higher rewards compared to lower effort tasks with less compensation .
Due to stimulants’ ability to improve motivation, Adderall is currently used to treat apathy in brain disease and psychiatric patients .
Adderall can make some people more jittery, while dextroamphetamine can provide a more subtle mental effect.
Healthy university students who used Adderall reported an increase in :
- Energy levels (both body and brain)
- Sense of well-being
- Drive to complete a task or achieve a goal
- Interest and emotional investment in their work
- Enjoyment in the work
2) Methylphenidate (Ritalin)
- Improved attention in a study (double-blind randomized controlled trial) of children with ADHD .
- Increased activation and connectivity of brain networks important to reward .
- Increased motivation to perform an ongoing task .
Methylphenidate (Ritalin) Mechanisms
- Increases dopamine in the brain .
Modafinil is a wakefulness-promoting drug for treating excessive sleepiness. It is also widely used off-label as a cognitive enhancer.
- In non-sleep-deprived patients, Modafinil reduced fatigue levels and reaction time, while improving motivation and vigilance .
- Modafinil enhanced highly-demanding cognitive performance in healthy individuals (double-blind randomized controlled trial) .
- Modafinil (200 mg/day) notably increased task performance and enjoyment, as well as creative thinking in healthy patients (double-blind randomized controlled trial) .
- Increased motivation in mice .
- Proposed to weakly inhibit dopamine reuptake transporters, preventing the decrease of dopamine, however, this theory is controversial [R, R].
- Increases other neurotransmitters including the histamine orexin, norepinephrine, and serotonin .
Adrafinil is a discontinued, non-FDA approved wakefulness-promoting agent, formerly used in France to promote alertness, attention, wakefulness, and mood, especially in the elderly.
Adrafinil in Animals:
- Improved discrimination learning (in aged beagle dogs) .
- Improved motivation and depression symptoms (in mice) .
- Thought to work similarly to modafinil, but more research needs to be done to determine how it works.
It does not possess any addictive potential and has no serious side effects .
Bromantane supplementation increases the ability to handle physical and mental loads (actoprotector) .
- Increases dopamine through tyrosine hydroxylase and amino acid decarboxylase [58, 59].
- Reduces oxidative stress, which plays a role in motivational deficits and psychological disorders [60, 54, 61].
6) Selegiline (L-Deprenyl)
Selegiline helped with:
- Motivational incentive (in dogs) .
- Severe apathy associated with traumatic brain injury .
- Protecting dopamine neurons, and was shown to be well tolerated in Parkinson’s Disease .
- Enhances Dopamine D1 and D2 receptors .
- Increases dopamine .
- At low doses inhibits MAO-B, preventing the breakdown of beta-phenylethylamine, dopamine, tyramine, and benzylamine [69, 70].
- At higher doses inhibits MAO-A, preventing the breakdown of dopamine, serotonin, norepinephrine, and tyramine [69, 71, 72].
Semax is a drug developed in Russia prescribed primarily for its cognition-enhancing effects.
Patients with a motor neuron disease had a significant emotional and motivational increase after being administered Semax .
Semax improved food motivation in rats that were isolated from birth .
Users report benefits such as:
- A stimulation compared to mild Adderall
- More interest in things
- Removal of lethargy
- General enthusiasm
- Social motivation
- Decreased procrastination
Some side effects include:
- Hair thinning
Semax is generally well tolerated, and often side effects are from using too much or a stronger version like NA-Semax, or NA-Semax-Amidate .
Tianeptine is an antidepressant.
In rats, tianeptine injections prevent stress-induced changes in the hippocampus, thus reducing the stress-induced reduction in motivation .
- Enhances dopamine release in the brain and increases dopamine receptor D2 and D3 activity .
- Blocks stress-induced changes of long-term potentiation (LTP) in the brain (hippocampus, prefrontal cortex) .
- Normalizes glutamate levels .
It is a rather subtle nootropic and may be best as an addition to a stack.
- Increases choline activity in the hippocampus [85, 86].
- Reduces dopamine release from the prefrontal cortex, increasing dopamine (D1 receptors) .
LSD-Microdosing has Little Clinically Relevant Studies, but User and Researcher Discussions are Available:
“I’ve micro-dosed with LSD quite extensively and it yields the best results akin to a cup of coffee in wakefulness and a similar boost in creativity as weed (without the lethargy of course)” .
It was ranked 8th in terms of the impact it had on motivation by redditors in nootropics.
LSD Microdosing Mechanisms of Action for Improving Motivation are not clinically clear.
Joe has tried micro dosing and did not see improved acute motivation. It could be that by making people happier/positive and less anxious, they become more motivated.
Racetam Drugs and Motivation
11) Phenylpiracetam (Phenotropil)
Phenylpiracetam, prescribed as Phenotropil, is a more potent phenyl-derivative of piracetam.
It induced stimulant effects that lasted for approximately 4 hours (in mice) .
In patients with brain diseases, phenylpiracetam improved coordination, higher brain function, and attention .
In animals, Phenylpiracetam:
- Increased the workload at which mice are willing to perform to obtain more rewarding drugs .
- Reduced depression [91, 89].
- Increased exploratory behavior and movement in mice impaired by a dopamine blocker (Haloperidol) .
- Improved operant conditioning (learning behavior modified by reward and consequences) in albino rats .
- Phenylpiracetam is thought to act by selectively inhibiting dopamine transporters, which increases dopamine levels and improves mood and motivation [94, 95].
- Reaction Time (in patients with degenerative dementia) .
- Cognitive Function (in patients with degenerative dementia) .
- Disturbances of the circadian rhythm (in rats with a disease of blood vessels in the brain) which are associated with a reduced response to reward [97, 98].
Oxiracetam studies in animals:
- Improved performance in the multi-trial avoidance task (in mice) .
- Improved both active and passive avoidance tasks when combined with nicotine (in mice) .
- In rats with brain damage from an acetylcholine inhibitor, Oxiracetam significantly improved learning ability during active-avoidance (pole climbing) tests .
- Enhances AMPA glutamate receptors in brain cells, which helps increase motivation [101, 102].
- Increases acetylcholine in the brain, important for mediating arousal [100, 103].
Sunifiram is a research chemical with a significantly higher potency than Piracetam.
It has not been tested for safety, or been in any human clinical trials, and is not approved for use anywhere in the world.
Sunifiram mechanisms for improving motivation are not clear.
Factors that Reduce Motivation
1) Poor Circadian Rhythm
Circadian gene mutations have been linked to an unusual response to reward .
Changing your sleep schedule on different days was associated with reduced responses to reward.
Nearly 43% of the mammalian genome is estimated to be rhythmic clock-controlled-genes critical to mood and reward .
2) Sleep Deprivation
REM sleep deprivation reduced motivation (in rats) .
Avoid room light exposure, and blue light (tv, phones, computers) before bedtime as light is associated with a decrease in melatonin onset and duration, and negatively affects sleep, and the circadian system [110, 111].
