This, in combination with Natural Stacks Serotonin, Ciltep and Smart Caffeine (they added L-Theanine so that one doesn't get jittery like some caffeine pills or nootropics), are an amazing way to start your day. Then, after lunch I take another of these, Dopamine, and another Natural Stacks Serotonin, and I am no longer drowsy in afternoons, nor am I irritable. These stacks by Natural Stacks aren't the big bang in the morning and afternoon, they are the smooth flow throughout my day. I stopped taking them for a while and that's when I noticed the difference in my life with Natural Stacks and without Natural Stacks, and I have to say that I prefer my life with Natural Stacks. I am a 55 yo woman, and I am a teacher - these products really help me to stay positive throughout the day, and again, the Dopamine and Serotonin shots in the afternoon help me to be the awesome, positive, teacher that I am in the morning. I am allergic to most prescription drugs and a few foods but I've not had one bad reaction to any of Natural Stacks products -this is probably due to the fact that they use non-GMO, all natural supplements (no synthetic ingredients) AND you will NEVER see the words "proprietary blend" on their ingredient list. I no longer trust "proprietary blend" because any dose can be in that blend - it seems that a lot of nootropics on the market have similar ingredients (I haven't seen any other nootropic out there using dried artichoke extract) but in dosages either too low to do any good, or too high which makes one a bit high - not in a good way Once you subscribe to their email newsletter you will get notice of flash sales, some are private to subscribers only- these are huge discounts that allow me, on my teacher's salary, to be able to afford continuing to take these stacks. I'm putting the Amazon link here for the CILTEP so that you can check out their flagship product which is made with 5 ingredients: artichoke extrace, Forskolin, L-Phenylalanine, Acetyl-L-Carnitine (ALCAR), and Vitamin B6. I won't be without Ciltep to start my day! It took me about 2 months to work out the perfect dosage for me - not everyone is the same, so try until you get it right for you. Ciltep Nootropic Stack - Natural Drug and Brain Booster for Optimal Mental Performance, Increased Focus, Improved Memory, Enhanced Motivation (2 Pack) I've read some of the other reviews - and everyone is different. But I will say that I've been researching and trying different nootropic stacks that are on the market, and for me, Natural Stacks is exactly what I wanted and needed. Thanks Natural Stacks for making great products. I was NOT paid, coerced, or given any future discounts to write this review. I wrote this review because, most of the time, I base new purchases on what the reviewers have to say about the product, and when a product is as good as this one, I want to tell the world about it.

Helps keep you going throughout the day. My bottle was sealed and intact, and there was nothing wrong with the capsules. Quality control got better I guess. Read more

I never take the time to write reviews but I have to for this dopamine brain food. I take medications that mess with my brain chemistry way too much. I've been exhausted, not excited to do anything and very sad. I've been taking this for about a week and already see a huge difference. I'm so much happier and definitely more driven. Keep in mind that everyone is different. I noticed that taking 3 at a time made me a little anxious. I now take 2 in the morning and 1 in the afternoon. I'm feeling more like myself for the first time in a very long time. If you suffer from exhaustion and zero drive, this is definitely worth a try. I hope this review helps you. Read more

Keep in mind there's no such thing as a supplement that contains Acetylcholine. The ingredients in the supplement cause the body to create acetylcholine. *My Experience* After taking the first capsule, I felt the effects within a couple of hours. I had more energy, more focus, and they seemed to stabilize my mood. After taking 1-2 capsules daily for about a week, I started getting really bad anxiety when trying to fall asleep. This is something I've never experienced before. Every time I was falling asleep my body would jerk and an intense fear would come over me. This would keep happening for several hours until I finally fell asleep. After doing some research, these were symptoms of too much acetylcholine. The half-life of Acetylcholine is about 13-15 days. Meaning once you get your reserves built up, you should stop taking these for about a month. Other symptoms experienced from too much Acetylcholine - Loose stools - Tight sore muscles - Jittery - Feeling like my muscles were vibrating under my skin. - Muscular fasciculation - small muscle contractions Due to the long half-life of Acetylcholine I suggest the following - Make sure to only take one capsule at a time. - Never take any after 3pm or you wont be able to go to sleep and will have the jitters. - Once you feel like you can focus discontinue use for a while.

Why did you pick this product vs others?: Be careful with this product. Within a week of taking this I was feeling really good— more focus, less anxiety, etc. However, after a couple weeks I started getting depressed and having darker thoughts. I did some research and it’s a known side effect of this supplement because it can cause some B vitamin depletion, among other things, so people recommend taking a B complex with this. I tried it and the dark thoughts seemed to subside a bit. Then I ran out of it and it took me 4-5 days before I could reorder. I took 3 pills the day I restarted taking them, and had a beer that night for my friends birthday, and had an awful reaction. I stared having intense suicidal thoughts and I just wasn’t myself. I had an anxiety attack and was hyperventilating and shaking. It was extremely concerning. This hadn’t happened before, either while drinking or drinking on this supplement, so I’m assuming it was because I took 3 after being off of them for 4-5 days. Proceed with caution. It does seem to work, but just be aware of this possible side effect. Read more
