Two popular nootropic stacks

I’ll start each nootropic post with the two paragraphs below.

Nobody should be putting anything into their body without weighing both the risks and benefits first. What I share on this site is only skimming the surface of nootropics. Nothing I share should be construed as advice. Do your own due diligence and educate yourself.

I want to make one point clear. The boost nootropics provide is only available with continued use. In other words, if you stop taking the nootropics the gains that have been made will begin to diminish back to prior levels.

Caffeine & L-theanine

I started with a simple stack (a stack is a combination of 2 or more supplements) of caffeine and L-theanine. My ratio was 2:1 in favor of L-theanine. I felt the best results with 200 mg of L-theanine and 100 mg of caffeine. At this level I experience the stimulating effects of caffeine but none of the irritating side effects like anxiety, increased blood pressure, and trouble sleeping.

In addition to neutralizing the common side effects of the caffeine, the L-theanine noticeably enhances my attention. I only take this stack when I’m really needing to focus on a project such as writing or research. I also won’t take this stack after 2 pm because I’ll have trouble getting to sleep that night and that is counterproductive in my book. The brain needs sleep.


Racetams are considered the oldest nootropics. Dr. Giurgea synthesized piracetam in 1964. However, not all racetams are nootropics. Here are the ones I’ve read about:

I took a stack of phenylpiracetam and choline for one month. I didn’t feel the effects until after taking it every day for ten days. The racetam needs to build up in your body so patience is needed as well as diligence in taking it daily. I noticed clarity of thought when taking this stack as well as an increase in mental endurance.

Choline is needed to help the racetams cross the blood/brain barrier ( choline is one of the rare substances that can cross the blood/brain barrier). Choline helps maintain healthy synapses and membranes in the brain which tend to deteriorate with age. It’s found naturally in many foods but sadly most people don’t eat a healthy diet (a pound of broccoli contains 180 mg of choline) so a supplement is needed.

I took 600 mg of Alpha-GPC once daily for the choline and 200 mg of phenylpiracetam twice a day with the first dose on an empty stomach. thing in the morning. The choline allows the stack to break the blood/brain barrier and thus effective. If you do not have enough choline in your system you either suffer a massive headache or not feel the effects of the stack.


  • If you take L-theanine with piracetam it will inhibit some effects from piracetam. L-theanine is a partial inhibitor of AMPA receptors.
  • Drink plenty of water (you should anyways) when taking piracetams as they have water soluble properties.
  • More is not always better, especially with nootropics. In other words, don’t take crazy amounts of racetams and choline expecting to instantly “feel” it.

Coming up next I’ll post about Forskolin & artichoke extract. Wait, what?
