I tried PEAK because I highly suspect I have undiagnosed ADHD. I read that these particular ingredients can help. I combine this wok Lion’s Mane and I notice a SIGNIFICANT increase in my ability to not only start tasks, but have the energy to follow through and finish them. I am able to focus!

I’m trying to cut down on coffee bc of its acidity is contributing to my reflux but I need the caffeine, so I’ve been taking Peak in the morning to give me the energy I need to get going. I’m sensitive to caffeine and only 1 pill gives me the energy for the day, without the jitters that sometimes I get from coffee. Peak is a good supplement to have in hand for the days that I’m doing intermittent fasting, too, bc it gives me the energy I need without the need to drink coffee

It gives me a steady run of energy throughout the day. I usually just take one in the morning and keeps me focused

I have been taking this as a way to skip the extra cup of coffee but get energy when I need it! I've noticed a total boost in energy and ability to work in my day to day AND I feel SO good without the crash. The l theanine really allows me to take this without the anxiety from the caffeine! 10/10 product!

I’m a legion athlete and recently gave these a try! Usually I never take caffeine, and when I do, I get these strange sensations and headaches. But not with Peak! I felt good natural clean energy, and it had transformed me into a regular caffeine user (mostly for athletics).

I get plenty of energy from Pulse for my morning workouts so I've been using Peak as a great afternoon pick me up. Being able to take 1 to 4 pills depending on how much energy I feel like I need too makes these a great option.

I really liked the boost of energy from this. I prefer to use on the days I dont go to the gym to help give the energy to do house or yard work but also use on cardio only gym days and it gives me the boost I need! Legion Athlete!!

I love peak! I’ve been looking to quit drinking energy drinks and this supplement helped me do just that! Caffeine + L-theanine. No more jitters or crash. I love how this makes me feel. Just good clean energy.

I love the combo of caffeine and L-Theonine. Pretty convenient in a pinch (like when traveling) but not quite as smooth as the energy/boost of Pulse. Would prefer a smaller pill. These are pretty big.

As a Legion athlete, I gave Peak a shot and I’m impressed. Clean energy, no crash, and it actually helps me push through that mid-day slump. My friend even said it was helpful for them since they love coffee midday!

I can tell a difference while using this product doing fasted cardio in the mornings 🙌🏽

I often feel fatigue throughout the day, so I was excited to see Legion was offering a product to supplement that. The first time I took them, I wasn't feeling any different than how I normally do. I attributed it to my body needing to adjust. After taking it a few more times, I still did not feel either instant burst or gradual building of energy. I know other people react differently so I think Peak just isn't for me.

As a legion athlete, I recently had the chance to try the Peak product. I usually hit a wall mid afternoon. I wanted to find something to replace my afternoon coffee with and peak intrigued me. I’ve been very pleased with it. It’s a much cleaner feeling burst of energy than you would get from the caffeine you get in coffee. And there is no crash afterwards either. Definitely recommend the product.

On days when I want a quick boost of caffeine these come in so handy. No jitters just good energy with no crash afterwards!

I love all of these products but this taken with the fat burner made me feel bloated and uncomfortable. Not sure which one it was. I stopped taking this though. ;/

I have been taking one capsule after lunch every day and I feel so much more energy to crush the second half of the workday. I love the Theanine mixed with Caffeine, I feel totally focused and calm with a laser focus. Highly recommend and super convenient!

I like drinking coffee for caffeine, but these are so convenient. They work almost immediately.

Really loving this. It’s the perfect afternoon supplement for me. When I still have a couple hours of work to do so need a little pick me up but not anything that will make me crash OR keep me up at night. I have this in my car, home, gym bag etc. So easy to take whenever needed!
