The Basics

What are nootropics, and how do they work?

Nootropics are a class of compounds that enhance cognitive function by helping to promote neurotransmitter activity to support motivation, mood, memory, and focus. Some of the most widely consumed nootropics are caffeine and L-theanine, found in coffee and tea.

Whether you’re looking to enhance your productivity, maintain mental sharpness, or improve working memory, nootropics can offer a range of benefits to support your cognitive goals.

What is personalized about your nootropics?

We developed six unique nootropic blends designed to cater to different cognitive goals. Our quiz assesses various traits to pinpoint areas with the greatest potential for improvement (e.g., focus, energy, motivation, etc.).

Based on your quiz results, we make personalized recommendations to match you with the four blends we think you’ll experience the most benefits from. The Starter Kit contains four blends, designed for you to try a new blend each week, moving you closer to the blend that best complements your personal brain and goals.

Can I select my blends instead of getting a Starter Kit?

Yes. If you have a clear idea of which blend(s) you want to try, you can customize your next refill on the Build Your Box page.

If you already took the quiz and want to adjust your blends but the order has already been processed, contact us right away at 646-647-3599 or email us at so we can help.

Do you offer caffeine-free blends?

Yes! You can choose to receive a caffeine-free version by selecting the Caffeine-free toggle on the Build Your Box page.

If you would like to make adjustments to your blends after taking the quiz, please email us at so we can update your order to caffeine or caffeine-free.

If you’ve already received the caffeinated blends and do not want the caffeine, you can simply remove the white capsule from each packet, which contains all the caffeine content within each blend.

Where can I find more information on each ingredient?

If you want to learn more about the science behind each ingredient, check out the Ingredients page on our website.

To discuss the function or science behind our ingredients, speak with any of our Coaches by calling us at 646-647-3599 or emailing us at

Can I open the capsules and pour them into water?

You can — but we don’t recommend it. We encapsulate the ingredients because they have a strong, unpleasant taste. If you have a hard time swallowing capsules, it is perfectly safe to mix the contents into a smoothie, juice, or flavored drink to help mask the taste.

I want to try before I buy. Do you offer free samples?

We don’t offer free samples. However, if you aren’t happy with Thesis, we will offer a refund within 30 days of your first delivery.

Month 1: What to Expect

How does the Starter Kit work?

The Thesis Starter Kit introduces you to four unique blends, each designed to be tested over one week, helping you discover which blend best aligns with your neurochemistry and goals.

You can begin your Starter Kit journey with any blend. Start by taking one full packet each morning for six consecutive days, followed by one day off, before moving on to the next blend.

It's important to monitor how each blend affects you, tracking changes across traits like memory, alertness, mood, and productivity. At the end of the four weeks, the goal is to identify the one or two blends that benefited you the most.

For subscriptions, remember to customize your next box through your Thesis Account before your next shipment.

If you opted for a one-time purchase, you can select your preferred blends for your next order by visiting the Build Your Box page.

Should I take Thesis blends with food or on an empty stomach?

We recommend taking Thesis blends on an empty stomach to maximize the effects and absorption of the ingredients. However, if you have a sensitive stomach, your blends can be taken with a meal or light snack to make them more tolerable.

Can I still drink coffee?

Yes. For most Thesis users, you can continue to enjoy coffee even if you’re taking our caffeinated blends. Keep in mind, that our caffeinated blends contain 100 mg of caffeine and 200 mg of L-theanine, which is roughly equivalent to a cup of coffee, so depending on your sensitivity, you may want to monitor your total caffeine intake.

Many Thesis users have even reported that their coffee consumption has gone down and become less reliant on coffee to energize them throughout the day.

If you’ve received the caffeinated Thesis blends and do not want the additional caffeine, you can simply remove the white capsule from each packet, which contains all caffeine content within each blend.

How long until I start seeing results?

Many Thesis users will begin to notice the initial effects within 60 to 90 minutes after taking it. But depending on your body's metabolism and your familiarity with nootropics, it could take a few days of consistent use for the full effects to ramp up. So, patience is key!

For long-term improvements in cognitive performance, consistent use is crucial. Once you've found the blend that best suits your brain chemistry, give it about 4-6 weeks to gauge the true changes and benefits.

Are there any known side effects?

Experiencing side effects like headaches, nausea, anxiety, or agitation can occur. If discomfort arises it's important to listen to your body; this could mean adjusting the dosage, spacing out the intake, or switching to another blend. Identifying what doesn't work is just as important as finding what does.

It’s important to remember that everyone responds differently to supplements, so we recommend you discuss any effects you may experience with your doctor.

If you would like more information, contact us at 646-647-3599 or email us at to speak with one of our Thesis Coaches.

What happens if I don’t like one or more of my blends?

Discovering that a blend isn't right for you is normal and a positive step forward! It's all part of the optimization process to help you pinpoint the nootropic blend(s) that best enhances your cognitive function.

If you aren’t noticing any effects from a blend after taking it for six consecutive days, it's a sign to adjust your selection for the next month.

If you need more guidance on assessing the effectiveness of each blend, our Thesis Coaches can provide recommendations and tools to make this process easier. Give us a call at 646-647-3599 or send us an email to

Do I need to take all of the capsules in a packet?

While the capsules in each packet are based on dosages shown to be effective, we understand that everyone's body reacts differently.

The nootropic ingredients are evenly distributed across the brown capsules, allowing you to adjust your dosage by adding or removing these capsules. The white capsule in each packet only contains caffeine and L-theanine, giving you more flexibility on what you need each day.

If you’re interested in increasing the dosage beyond the recommended capsules in each packet, please consult with one of our Coaches by calling us at 646-647-3599 or emailing us at

I finished my Starter Kit. What do I do now?

Congrats! Finishing your Starter Kit is a significant milestone towards helping to improve your cognitive performance.

The next step is selecting the one or two blends that benefited you the most, even if the changes were subtle. Now, you can start fine-tuning your experience, using your blends based on what you need that day (e.g., mental clarity, energy, motivation, and so on).

During the second month, continue to pay attention to the changes in your cognitive performance and well-being. Before long, you'll find yourself settling into a rhythm that feels right.

Month 2+: What's Next

Can I try the blends that were not included in my Starter Kit?

Absolutely! We have six unique nootropic blends, so if you’re interested in trying the remaining blends that weren’t in your Starter Kit, we encourage you to keep experimenting.

If you choose to go with a new blend, the same recommendations apply: use the blend for six consecutive days to allow your brain and body to adapt to these new ingredients before determining its effect.

How often should I take my blends?

Thesis is designed for daily use–with intentional rest days built in. Incorporating 1-2 days off per week can prevent building up a tolerance to your blends and allows you to reassess your baseline.

If you have a very busy week, you can take your blends all seven days; just adjust for next week by taking two rest days.

What happens if I take more than the recommended dose?

Although our blends were formulated to be taken once daily, we understand some days require extra support. If you need to extend past the typical 4-6 hour half-life, taking a second packet four hours after the first is safe. Of course, everybody responds to supplements differently, so please listen to your body.

Please don’t exceed two packets in any 24-hour period. Additionally, be mindful of taking a packet within eight hours of your planned bedtime as disturbing your sleep is counterproductive to your cognitive health.

Can I take more than 1 blend per day?

Yes. While Thesis aims to identify your single optimal blend, we know for some, two blends might be needed to cater to different requirements throughout the day.

If you choose to take two blends in a day, we recommend spacing them at least four hours apart to prevent any potential interactions or absorption issues.

For personalized advice on combining blends safely and effectively, please speak with one of our Coaches who can help tailor recommendations to your specific needs and goals.

What are the long-term effects?

In clinical trials, none of our ingredients show negative long-term effects. Many nootropics become more effective over time due to the compounding effects on brain health and the structural integrity of neurons.

Early research studying the long-term effects of certain nootropics ingredients shows improvement in cognitive traits like memory retention, cognitive flexibility, and focus following persistent use.

Do benefits continue even after I stop taking my blends?

One of the remarkable benefits of nootropics is the neuroprotective effects that promote the long-term health of our brains.

For example, by increasing Brain-Derived Neurotrophic Factor (BDNF) in the brain, nootropics promote adaptability to improve traits such as attention, learning, and emotional regulation–when paired with deliberate effort, such as challenging yourself with complex puzzles, practicing a skill, or trying to remember information without looking it up.

For a comprehensive overview of our ingredients, their respective benefits, and the latest clinical research, please visit the Ingredients page on our website.

Will I become reliant on taking my blends?

No, you won’t develop a dependency on any of our blends. Because nootropics are non-habit-forming compounds, you have the flexibility to pause or stop taking them without experiencing unwanted side effects.

Quality Control & Manufacturing

Where do you source your ingredients from?

Our ingredients are globally sourced to ensure we're using the best available, but all our products are manufactured right here in the U.S.

We utilize a combination of natural and synthetic ingredients for consistency and control, like our lab-created caffeine, which reduces batch variability.

How do you test for purity and potency?

To guarantee each blend meets our high standards for purity and potency, we conduct regular third-party lab testing. Unlike many supplement brands, our blends contain minimal fillers and always use the most bioavailable form of active ingredients.

Do you have third-party testing?

We rely on third-party labs for detailed testing to ensure each ingredient and finished product matches our standards for concentration and purity.

All of our products go through rigorous quality control testing, as well as batch-specific COAs (Certificate of Analysis) for all raw ingredients and finished goods, emphasizing our commitment to consistency and safety.

What is the shelf-life of your blends and how should they be stored?

Our blends have a two-year shelf life and maintain their efficacy when stored at room temperature.

Are your ingredients allergen-free and/or vegan?

All our ingredients are vegan and free from gluten, eggs, and nuts. While our manufacturing process is designed to minimize any cross-contamination, our facilities process other products, so we cannot offer certified vegan or gluten-free guarantees.

Are your blends FDA-approved?

In accordance with manufacturing practices in the United States, dietary supplements do not go through pre-market FDA approval. Thesis follows current Good Manufacturing Processes (cGMP), which are maintained by the FDA to ensure proper supplement manufacturing. FDA regulates everything from raw material selection to product safety to labeling.

All of our ingredients are classified by the FDA as Generally Recognized as Safe (GRAS) or have undergone phase III clinical trials, which both establish measures of safety.

Subscriptions & Shipping + Orders

How does my subscription work?

At checkout, you have the option of selecting the subscription model priced at $79 or opting for a one-time purchase for $119.

By selecting the subscription option, a new order will be shipped to your address every 28 days unless any adjustments have been made to your subscription in your Thesis Account.

You can select or update your blends or reschedule your next order if you're traveling or have simply fallen behind on taking them and have a surplus of packets.

Can I pause my subscription?

You can do this by logging into your Thesis Account, selecting "Manage Subscription” in the “My Subscription” tab, and scrolling to the bottom of the page.

Do you offer refunds or returns?

Yes. If you are not 100% satisfied with your purchase, you may request a refund within 30 days of delivery of your first order. We’ll refund you for the full cost of the product, including shipping.

Refunds apply to your first order only. For subsequent orders, you may reschedule, skip, or cancel at any time in your Thesis Account.

Expedited shipping methods are available for one-time purchases on our website, however, if you’re a Thesis subscriber and would like an expedited shipment, please email us at or call 646-647-3599.

For all standard and expedited shipping methods, orders placed on Friday after 12 PM ET will be processed on Monday to ship.

How can I track my order?

By logging into your Thesis Account and navigating to the Order History tab, you’ll be able to track your order by clicking on the order number.

If you’re experiencing issues finding the tracking information, please contact us at with your order number.

Why hasn’t my order tracking updated?

Movement on your tracking link can take up to 24 hours to update. If you continue to see no movement after 24 hours please contact us at with your order number and we will look into it further.

Why does the DHL tracking show a different date from USPS tracking?

DHL tracking updates are based on USPS updates. In some cases, the DHL tracking will show a later delivery date initially and then update once USPS has a more accurate estimate.

Additionally, DHL hands off the package to USPS in the last leg of delivery, so when this happens your order is often delivered within a couple of days.

Why does my tracking link show it was delivered, but I didn’t receive it?

Please check in and around your mailbox, or check with your neighbors to see if the package was mistakenly delivered to them.

If you still can’t locate your package after 48 hours, please contact us at

Do you ship internationally?

Due to complexities with various customs regulations, we don’t currently ship internationally.

We do, however, ship to all 50 U.S. states and the five major territories (American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and U.S. Virgin Islands).

Can I change my shipping address after placing my order?

We’ll do our best to make any updates to your order before it has left our fulfillment center.

The fastest way to contact us is by calling 646-647-3599 between 10 am - 5 pm ET or sending us an email at, with your order number, original shipping address, and the new address you wish to change to.

Health & Safety

Can I take Thesis while on antidepressants, stimulants, and non-stimulant medications?

Psychopharmaceutical medications, including antidepressants, stimulants, and non-stimulants, may interact with ingredients in Thesis, potentially leading to adverse or combinatorial effects.

It’s important to speak with your primary medical provider before starting any new supplement or altering any course of medication. They will be able to provide the best advice regarding the safety of adding Thesis to your routine.

Are there any pre-existing conditions that make someone ineligible to take Thesis?

You should consult your primary medical provider before taking Thesis blends, especially if you are pregnant, planning to become pregnant, are breastfeeding, or have a history of any of the following: high blood pressure, heart disease, chest pains, stroke, seizures, high cholesterol, obesity, psychiatric conditions, if you smoke, or have a health problem that could be made worse by a change in diet or supplement routine.

Does Thesis replace my ADHD medication?

Our blends and many stimulant or non-stimulant medications will impact the same neurochemical systems (e.g., dopamine, norepinephrine, and serotonin) involved in mood, attention, energy, and focus.

While Thesis may support cognitive function, it is not designed to treat, cure, or replace medication for ADHD or any other medical condition. Discuss with your healthcare provider for guidance tailored to your health needs.

Can I take Thesis if I’m under 18?

Our product is one of the most comprehensive nootropics systems on the market and our ingredients are backed by hundreds of clinical research papers.

Unfortunately, the research conducted on these ingredients did not include participants who were under the age of 18. We advise against children taking our product and encourage you to consult a pediatric healthcare provider for advice tailored to minors.

Is it safe to take if I’m pregnant or breastfeeding?

Our product is one of the most comprehensive nootropics systems on the market and our ingredients are backed by hundreds of clinical research papers.

Unfortunately, the research conducted on these ingredients did not include participants who were pregnant, nursing, or breastfeeding. For that reason, you should always consult your healthcare provider before starting any new supplement to ensure it is safe for you and your baby.

Can I use my HSA or FSA account to pay for Thesis?

Most FSA and HSA programs will cover the cost of prescription medication; however, since our supplements do not fall into the prescription category, you may not be eligible for reimbursement through your FSA or HSA program.

Consult your HSA or FSA plan administrator to confirm which types of supplements, if any, are eligible for reimbursement under your specific plan.
