I loved Thesis in the beginning

I loved Thesis in the beginning. I was a customer for 4 years. In March 2026, they changed their formula, changed from convenient packets to a glass bottle without child resistant lid, and raised their prices. It was already kinda pricey at $85 per month. It's my time to try something else.

Don’t do it

Decided to try a bottle to see what the hype was all about, huge mistake. This product is a complete waste of money… I get a better result from a cup of coffee. Don’t fall for the fake ads and reviews like I did. Also they auto-subscribe you so if you aren’t paying attention they will send you a new bottle with no refund options only store credit. Stay away

This is the best product I have ever…

This is the best product I have ever tried in my life. It’s the Motivation and Confidence blends for me. The Motivation blend keeps me focused on my task ALL day. I am knocking out to do list left and right. I had a supervisor that was a real B****. The Confidence blend kept me relaxed and calm on the days she was on her broom. When I applied for another position the last 3 days working for her would have been HORRIBLE but the Confidence blend kept me so calm everyday. I will continue to use Take Thesis to help me in my new position to help me through the rough days, whether I need to focus or need to stay calm I know the Confidence and the Motivation blends will get me through.

Clarity is great for my ADHD

I have ADHD and I’m prescribed Vyvanse. When pairing that with Clarity I feel it’s the ULTIMATE combination.

When I don’t have my Vyvanse because it’s always out of stock, I feel like Clarity gives me the boost I need to keep focused.

I really like the energy and sense of well-being that I get from Thesis. I've found the blends that work best for me, but it was interesting to try them all and to hear how others find the different blends work better for them. After trying it, I've stuck with it. I would say it's definitely worth a try for anyone.

I really love energy

I really love energy, it helps me with my midday slump, or if there's a bunch of chores i don't want to do, it helps give me the energy to tackle them

Way too expensive for nootropics

Way too expensive for nootropics. No noticeable effect aside from consistent caffeine/l-theanine. You can find similar blends online for a fraction of the cost if you’re interested. For the monthly cost you may as well get Actual Therapy or something similar

No more Adderal for me!!

No more Adderal for me! I've been able to successfully come off of adderal because of these blends. I feel a lot more like myself on them. I've been taking them since August 2023.

Stay away from this crappy company

Stay away from this crappy company. The pills don’t do anything and it’s impossible to unsubscribe. You can’t talk to a person only email and a phone number you can leave a message at. Definitely made to steal money. They say you can unsubscribe but there is no account you can login to. You need the receipt which they didn’t send by mail or email. Not even an email confirmation. Scammers!
