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.



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 [R].

Injecting dopamine blockers slows motivated reward-seeking behaviors [R].

Dopamine has also been highly accepted in reinforcement learning, a motivated learning process based on the incentive of reward [R].

Dopamine provides motivation due to an increased feeling of reward when tasks are completed [R].

How Humans Get Motivated

Cost-Benefit Analysis of Motivation Theory

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
  • Time
  • Loss of potential opportunities
  • Discomfort
  • 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 [R].

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 [R].

Apathy and disease-induced deficits in motivation are displayed in patients with disorders like:

8 Natural Drugs to Improve Motivation

1) Sunlight Improves Motivation

Sunlight exposure:

  • Increases available dopamine receptors, which helps increase dopamine levels [R]
  • Increases serotonin and its receptors, vital to mood and outlook [R]
  • Entrains the circadian rhythm and helps with sleep [R]
  • Raises endorphin levels, which increases motivation [R]
  • Increases productivity [R]

2) Flavonoids Improve Motivation

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.

In rats, cocoa flavonoids maintained high dopamine levels (urine) [R].

Blueberry flavonoids had an acute improvement of mood in children and young adults [R].

Flavonoid(s) Mechanisms

  • Increases dopamine by inhibiting the MAO enzymes [R].
  • In a rat model of Parkinson’s, some flavonoids (polymethoxylated flavones, procyanidins, and isoflavones) protected dopamine neurons [R].
  • Increases brain blood flow [R].
  • Prevents death of neurons [R].
  • Increases synaptic plasticity (the strengthening or weakening of synapses over time) [R].
  • May delay the progression of brain diseases [R].

3) Caffeine Improves Motivation

Caffeine is a brain stimulant and the world’s most widely consumed drug.

It enhances exercise capacity and reduces perceived efforts, suggesting that it can increase motivation to exercise in sedentary people [R].

Moderate doses of caffeine increased sexual motivation in female rats [R].

Caffeine improved motivation and cognitive performance in complex tasks (bees) [R].

Caffeine Mechanisms:

4) Pregnenolone Improves Motivation

Pregnenolone is a hormone that can increase reward-related processes and improve mood and motivation [R].

Rats’ motivational incentive increased after pregnenolone injections. They more easily found a reward in a new location [R].

Rats also had increased dopamine and dopamine responses to morphine (using pregnenolone sulfate) [R].

Pregnenolone reduced motivation deficits induced in mice (by a competitive NMDA activator) in active avoidance and lever-press learning tasks [R].

Pregnenolone Mechanisms

  • Increases steroid hormones such as allopregnanolone, which increases brain cell production, protects the brain and reduces cell death and inflammation [R].
  • Increases dopamine release and response [R].

5) Nicotine Improves Motivation

Nicotine potently activates the fight or flight nervous system and acts mostly on nicotinic acetylcholine receptors [R, R].

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 [R]:

  • Reinforcement of reward
  • Enhancement of performance

Nicotine is currently under investigation for the treatment of [R]:

  • Alzheimer’s disease
  • Parkinson’s disease
  • ADHD
  • Depression/Anxiety
  • Schizophrenia

Nicotine significantly improved motivation-driven behavior in rats [R].

Nicotine Mechanisms

  • Increases dopamine in the brain [R].

6) N-Acetyl-L-Tyrosine Improves Motivation

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, studies find that N-Acetyl-L-Tyrosine was the weakest of the tyrosine prodrugs [R].

NALT Mechanisms

  • Converts to dopamine through L-dopa

7) Rhodiola Rosea Improves Motivation

Rhodiola is often considered an adaptogenic drug (increases resistance to stress in nonspecific ways), used primarily for its cognitive and physical boosts [R].

In a study of 120 adults, 80% of patients reported “very good, or good” improvements in [R]:

  • Exhaustion
  • Decreased Motivation
  • Daytime sleepiness
  • Decreased Libido
  • Sleep disturbances
  • Cognitive impairments (concentration, forgetfulness, memory, stress, irritability)

In contrary, other studies (DB-RCT) failed to find significant differences between the effects of Rhodiola and placebos [R].

Rhodiola Mechanisms

  • Rhodiola inhibited MAOI-A and B in cell studies, which would lead to an increase in dopamine [R].
  • Stimulates the brain [R].
  • Prevents oxidative damage [R].

8) Tyrosine Improves Motivation

Tyrosine is the precursor to l-dopa, which converts to dopamine.

Dopamine is essential to motivation, cognitive deficits associated with depleted dopamine can be reversed with Tyrosine [R, R].

Tyrosine is unlikely to be effective unless you are lacking optimal dopamine levels, often correlated with psychiatric illnesses or drug abuse [R, R].

Tyrosine Mechanisms

  • Converts L-dopa to dopamine through the tyrosine hydroxylase enzyme [R]

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.

1) Adderall/Dextroamphetamine Improves Motivation

Adderall is a combination of amphetamine salts (25% Levoamphetamine, 75% dextroamphetamine) used in narcolepsy and ADHD.

Amphetamine increased user’s motivation to pick tasks with a higher workload with higher rewards compared to lower effort tasks with less compensation [R].

Due to stimulants’ ability to improve motivation, Adderall is currently used to treat apathy in brain disease and psychiatric patients [R].

Adderall can make some people more jittery, while dextroamphetamine can provide a more subtle mental effect.

Amphetamines are very addictive and should be used with caution. Abuse can lead to brain toxicity [R].

Healthy university students who used Adderall reported an increase in [R]:

  • 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

Adderall/Dextroamphetamine Mechanisms:

  • Increases dopamine by inhibiting dopamine reuptake [R].
  • Body and brain stimulation [R]

2) Methylphenidate (Ritalin) Improves Motivation

Methylphenidate is a brain stimulant commonly prescribed for ADHD and narcolepsy. It:

  • Improved attention in a study (DB-RCT) of children with ADHD [R]
  • Increased activation and connectivity of brain networks important to reward [R].
  • Increased motivation to perform an ongoing task [R]

Methylphenidate (Ritalin) Mechanisms

  • Increases dopamine in the brain [R].

3) Modafinil Improves Motivation

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 [R].
  • Modafinil enhanced highly-demanding cognitive performance in healthy individuals (DB-RCT) [R].
  • Modafinil (200 mg /day) notably increased task performance and enjoyment, as well as creative thinking in healthy patients (DB-RCT) [R].
  • Increased motivation in mice [R].

Modafinil Mechanisms

  • Inhibits dopamine transporters, preventing the decrease of dopamine [R].
  • Increases the histamine Orexin, which plays a role in reward [R, R].

4) Adrafinil Improves Motivation

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.

It is an analog of Modafinil [R].

Adrafinil may improve performance motivation and may increase libido [R, R].

Adrafinil in Animals:

  • Improved discrimination learning (in aged beagle dogs) [R]
  • Improved motivation and depression symptoms (in mice) [R]

Adrafinil Mechanisms

  • Inhibits dopamine transporters [R].

5) Bromantane/Ladasten Improves Motivation

Bromantane is a Russian drug with stimulating and anti-anxiety effects [R, R].

It does not possess any addictive potential and has no serious side effects [R].

Bromantane supplementation increases the ability to handle physical and mental loads [R].

Although Bromantane has few clinical studies, anecdotal results are available [R, R, R].

Bromantane/Ladasten Mechanisms

  • Increases dopamine through tyrosine hydroxylase and amino acid decarboxylase [R, R].
  • Reduces oxidative stress, which plays a role in motivational deficits and psychological disorders [R, R, R].

6) Selegiline (L-Deprenyl) Improves Motivation

Selegiline (L-Deprenyl) in smaller doses inhibits the enzyme MAO-B. In larger doses, it also inhibits MAO-A. This prevents the breakdown of dopamine and other neurotransmitters [R].

In Alzheimer’s patients, selegiline was more effective at improving cognitive functions and reducing impairments than oxiracetam [R].

Selegiline helped with:

  • Motivational incentive (in dogs) [R]
  • Severe apathy associated with traumatic brain injury [R]
  • Protecting dopamine neurons, and was shown to be well tolerated in Parkinson’s Disease [R].

Selegiline Mechanisms

  • Enhances Dopamine D1 and D2 receptors [R].
  • Increases dopamine [R].
  • At low doses inhibits MAO-B, preventing the breakdown of beta-phenylethylamine, dopamine, tyramine and benzylamine [R, R].
  • At higher doses inhibits MAO-A, preventing the breakdown of dopamine, serotonin, norepinephrine, and tyramine [R, R, R].

7) Semax Improves Motivation

Semax is a drug developed in Russia prescribed primarily for its cognition-enhancing effects.

Patients with motor neuron disease had a significant emotional and motivational increase after being administered semax [R].

Semax improved food motivation in rats that were isolated from birth [R].

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:

  • Overstimulation
  • Anger
  • Hair thinning
  • Headaches
  • Anxiety

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 [R].

Semax Mechanisms

  • Increases serotonin [R].
  • Enhances dopamine release when combined with d-amphetamine [R].

8) Tianeptine Improves Motivation

Tianeptine is an antidepressant.

In rats, tianeptine injections prevent stress-induced changes in the hippocampus, thus reducing the stress-induced reduction in motivation [R].

Tianeptine Mechanisms

  • Enhances dopamine release in the brain and increases dopamine receptor D2 and D3 activity [R].
  • Blocks stress-induced changes of long-term potentiation (LTP) in the brain (hippocampus, prefrontal cortex) [R]
  • Normalizes glutamate levels [R].

9) Sulbutiamine Improves Motivation

Sulbutiamine is a synthetic derivative of thiamine that crosses the blood-brain barrier better than thiamine. [R]

It is a rather subtle nootropic and may be best as an addition to a stack.

It has few clinically relevant studies, but user discussions are available: [R, R, R]

Sulbutiamine Mechanisms

  • Increases choline activity in the hippocampus [R, R].
  • Reduces dopamine release from the prefrontal cortex, increasing dopamine (D1 receptors) [R].

10) LSD-Microdose Improves Motivation

Lysergic acid diethylamide (LSD), also known as acid, is a psychedelic drug that in recent years has found potential as a treatment for conditions with micro dosages.

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)” [R].

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 acutely improved motivation. It could be that by making people happier/positive and less anxious, they become more motivated.

Racetam Drugs and Motivation

11) Phenylpiracetam (Phenotropil) Improves Motivation

Phenylpiracetam, prescribed as Phenotropil, is a more potent phenyl-derivative of piracetam.

It induced stimulant effects that lasted for approximately 4 hours (in mice) [R].

In patients with brain diseases, phenylpiracetam improved coordination, higher brain function, and attention [R].

In animals, Phenylpiracetam:

  • Increased the workload at which mice are willing to perform to obtain more rewarding drugs [R].
  • Reduced depression [R, R].
  • Increased exploratory behavior and movement in mice impaired by a dopamine blocker (Haloperidol) [R].
  • Improved operant conditioning (learning behavior modified by reward and consequences) in albino rats [R].

Phenylpiracetam Mechanisms

  • Phenylpiracetam selectively inhibits dopamine transporters releasing dopamine [R].

12) Oxiracetam Improves Motivation

Oxiracetam improved:

  • Reaction Time (in patients with degenerative dementia) [R]
  • Cognitive Function (in patients with degenerative dementia) [R]
  • Disturbances of the circadian rhythm (in rats with disease of blood vessels in the brain) which are associated with a reduced response to reward [R, R]

Oxiracetam studies in animals:

  • Improved performance in the multi-trial avoidance task (in mice) [R].
  • Improved both active and passive avoidance tasks when combined with nicotine (in mice) [R].
  • In rats with brain damage from an acetylcholine inhibitor, Oxiracetam significantly improved learning ability during active-avoidance (pole climbing) tests [R].

Oxiracetam Mechanisms

  • Enhances AMPA glutamate receptors in brain cells, which helps increase motivation [R, R].
  • Increases acetylcholine in the brain, important for mediating arousal [R, R]

13) Sunifiram Improves Motivation

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.

However, user anecdotes are available: [R, R, R, R]

Sunifiram Mechanisms for improving motivation are not clear.

Factors that Reduce Motivation

1) Poor Circadian Rhythm Reduces Motivation

circadian rhythm

Circadian Rhythm disruption is both a symptom and a pre-existing factor in many psychiatric diseases [R].

Circadian gene mutations have been linked to an unusual response to reward [R].

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 [R].

2) Sleep Deprivation Reduces Motivation

Sleep deprivation reduces dopamine function and dopamine receptors (D2) in the human brain (ventral striatum) [R].

REM sleep deprivation reduced motivation (in rats) [R].

Note: 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 [R, R].

    Thank you so much, just what I needed.

  • Neil

    You listed microdosing of LSD, but excluded microdosing of psilocybin?

  • Helen

    Caffeine blocks adenosine receptors, which can interfere with dopamine signalling and its receptors. When caffeine blocks A2A receptors, it can enhance dopamine receptors because D2 receptors are now free. We added another reference that talks about this. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4462609/

  • Coco

    why is ADHD not listed under the associated disorders/dis-eases when dopamine is the key element to it??? on the other hand AD(H)D is listed under nicotine? Is there a specific reason?

  • James Bond

    Where you state that caffeine leads to indirect increase of dopamine – the references text doesn’t say anything like this, can you clarify?
