PEAK ATP®

400 mg
PEAK ATP®️ is a clinically studied form of Adenosine 5’-Triphosphate (ATP), the body’s primary energy molecule.* It delivers immediate energy to muscle cells, helping fuel performance during exercise.* Supplementing with 400 mg of PEAK ATP®️ has been shown to increase muscular strength, endurance, lean muscle mass, and recovery.* It also promotes better blood flow, ensuring oxygen and nutrients reach working muscles more efficiently.* By enhancing both power output and recovery, PEAK ATP®️ helps you train harder and bounce back faster.*

Enfinity® Paraxanthine

200 mg
Enfinity®️ Paraxanthine is a purified metabolite of caffeine that delivers smooth, long-lasting energy without the typical crash or jitters.* At a clinically studied dose of 200 mg—the same amount found in Peak Energy—it has been shown to enhance focus, memory, and reaction time, while reducing cognitive errors by nearly 27%.* Unlike regular caffeine from coffee or energy drinks, paraxanthine provides cleaner stimulation and improved mental clarity.* It’s ideal for boosting both physical performance and cognitive function, helping you stay sharp, energized, and alert.*

Reviews

Best caffeinated coffee replacement

"I recently decided to try to decrease my caffeine intake and try to switch to decaffeinated coffee. I had read about Peak Energy and decided to incorporate it into my morning regime in conjunction with my decaf coffee and I experience NO HEADACHES as I gave up caffeine. I am thrilled. I don't have crashes anymore in the afternoon and I still feel energized and "awake" in the morning."

— Beth P. (5/5)

Peak Energy Has Been a Lifesaver!

"During perimenopause, I had a lot of problems with brain fog. I had tried another nootropic, which did help some. I decided to try Brain MD Peak Energy since I’ve followed Dr. Amen for a number of years and I really trust him. Peak Energy has helped me more than I could have imagined and my quality of life (and work!) has dramatically improved. I currently have a full-time job, teach at a university, and am starting a nonprofit so energy and focus are at a premium. I would highly recommend Peak Energy for anyone who struggles with brain fog in midlife. :)"

— Teri H. (5/5)

Afternoon pick me up

"I don't use Peak Energy every day. It is great for days when I am a bit short on sleep, or making a long drive late in the day. Alert energy without jitters or crashing. Highly recommend."

— Sharon P. (5/5)

Energized

"I've used Peak Energy by Brain MD, and it's been a consistent part of my supplement routine, What drew me in was the brand's focus on scientific based ingredients, and after a couple months of use. I can say it delivered where it counts most for me: focus and mental clarity."

— Pamela B. (5/5)

Really works!

"I'm on my second bottle of Peak Energy because it really works for me! Whenever I'm starting to feel that 3 pm slump, I take some Peak Energy and within 30 minutes or so, it perks me back up. And the brain energy lasts several hours too. I can't feel most supplements working, but this one I can feel. This is a supplement I will keep ordering."

— Carol V. (5/5)

Peak Energy powder

"I love this product. I drink it before and during my workout. Having said that, for some reason I am not getting credit for my product reviews. You reached out to me for a product review January 5th. I still have not received the credit for it."

— Peggy B. (5/5)

Makes workouts SO much easier

"This helped me with my super hard workout SO much. I’ve always avoided Bulgarian split squats because they were too hard for me. If I take this I can do as many as I need to, easy! I don’t notice a difference if I take it and don’t workout but I will never do another workout without it!"

— Jess (5/5)
