The product is good. No questions about that. What makes this a 4 star instead of a 5 start is their refill process. They refill you so often, before you could ever use the supplement you have on hand... Toon meer

I loved Thesis in the early days. I felt that I knew the ingredients and benefits of each variety, and I tried several before landing on my choice, Clarity, which strongly featured Lions Mane. But aft... Toon meer

The Clarity blend has always been my favorite, and it the only one I'm still currently taking. After about 3 years of taking this, I'm so much better at speaking and thinking deeply about everything.... Toon meer

First and for-most the blends work

First and for-most the blends work. On the rare occation I ran out...I felt the absence within two days. Additionally, customer support is quick, courteous and phenominal. I tell my friends about Thesis regularly.

Clarity seems to be the only thing that works for me.

I have apparently have ADHD. I've tried numerous supplements and Thesis - Clarity seems to be the only one that has worked for me. When I stop taking it within a day or so I begin to feel anxious and overwhelmed. I just wish it was less expensive, which is why I aways try to buy it when it's on sale.

I take it everyday

I take it everyday. I've tried so many different products to help with focus but this is the one that I actually stick with. It's been a few years now and it still works great!

Communication is hard

Communication is hard. Website is less than average, hard to navigate and use. Contacting company hard. Big disappointment from where Thesis was.

The product really works

The product really works. I find that I am much more productive and with less anxiety when I take Logic. And Clarity is wonderful before a performance or a long drive.

Customer service is always helpful!

I have been on another blend for a few…

I have been on another blend for a few months now. I cannot say that I am "exploding" with mental clarity and or memory. I have felt more cloudy when I missed two days in a row (Saturday and Sunday). This doesn't happen often but it has happened. When I am on it, I am not necessarily expedome of clarity and focus. I still get distracted, wondering if I should stay the course.

An appreciated support for my lifestyle

After a while of routinely using my preferred Thesis formulations, I found I could rely on them as needed based on what I was doing. I'm a very engaged DIY-er who, although retired and self-scheduling, benefits from the added support of Thesis - especially when I'm challenged to apply motivation, creativity, or logic to my projects. I highly recommend for anyone wanting to expand their toolkit of options for successful living.

As advertised

I really like the stress reset. This stuff works. I’ve found myself better able to relax, switch tasks, deal with stress, etc… I received a sample pack of the stasis nighttime and highly recommend as well. I’d like to try the clarity as I’m considering switching after 3-4 months of the stress reset

Thesis-5 stars. Their shipping company-0

My issue is not with Thesis as a company or the product they provide, it is with the shipping company, SpeedX, that they use to ship the product to me. From the time its shipped it always takes over a week to get it. Every month I always go in and have my shipment sent out a few days early to try to compensate for their incompetence but 2 times now in the last 6-8 months the shipment has just gone missing altogether and never arrived. Its very frustrating but I will say Thesis has been great both times in sending out another order free of charge. My review for Thesis would be 5 stars, the shipping company gets 0.
