    I really like this product as a micro dose. I use it on days when I go to the gym and days I take off. I usually do the 5 on 2 off micro routine. Love my boomerang.

    Taking this before a workout is a game changer. I can push myself past mental barriers that used to tell me “you can’t lift that much,” or “you cant hold a plank for that long,” etc. I hope this product never stops being made LOL. Thanks Sero!

    I use micro dosing mainly to keep my cluster headaches away but after I found Boomerang from Sero…game changer!
    All the benefits of a regular dose with the added performance enhancement. My workouts are supercharged! It feels like I have a training partner pushing me to do more. Motivation and focus maximized.

    No need for pre-workout anymore. I’ve been involved in bodybuilding my whole life, and this product has my performance at the gym beyond anything I’ve ever felt in my life. I’m focused and determined. I have nothing holding me back, I push harder and lift heavier and I have unlimited energy throughout my workout and for the rest of the day after. I am able to put my ego aside and get my training done. Euphoric energy, you have to try it.

      Grateful for you Christina, thank you for sharing your experience with Boomerang with the world!




Many people report landing on 125mg for their ideal dose.  If the immediate effect is too much, we recommend dropping your dose to 75mg, if the immediate effect is entirely unnoticeable, experiment with going up to 250mg.  To learn more about dosing click here


125 mg / 250 mg / 75 mg refers to the amount of magic mushrooms per capsule.


Note: Taking your microdose on an empty stomach will increase its effects.



The most popular microdosing protocol is one capsule, two times per week. For example, Saturday and Tuesday mornings.


While twice per week is common, many find increased benefits when microdosing three (or more) times per week. You have the freedom to pick any schedule that compliments your personal goals and lifestyle. The only rule we suggest is to take at least two days off per week.  To learn more about protocol, click here. 




Always remember, you are your own guide and you are in control. While microdosing, intention setting is something we highly encourage – it really can be a game changer in improving your results.


What are you hoping to feel or accomplish? Where do you want to go? Who do you want to be?


Some examples of an intention could be:


I want to improve my mood and quell anxious thoughts. 

I would like to gain better mental clarity and better focus at work.

I hope to become a more patient and present parent.

I aim to better integrate my therapy sessions.

I want to grow as an individual and open my mind. 


This list is never ending and your intention will be deeply personal.

Golden Teacher 75mg or 125mg or 250mg (depending on your selection)

Golden Teacher is a magic mushroom strain of psilocybin cubenesis. This beautiful teacher is known to provide guided uplifting experiences. It is also known to boost energy and provide focus. When paired with Boomerang's other ingredients, these benefits are amplified to help create the ideal microdose blend for physical performance.

Red Ginseng

(Panax Ginseng) has been used in traditional Chinese medicine for centuries. Ginseng contains two significant compounds: ginsenosides and gintonin which are known to complement one another and provide some excellent health benefits. The two that most benefit Boomerang include increased energy and anti-inflammatory support.


(Lepidium Meyenii) is a vegetable, related to broccoli and kale. It has several health benefits - including increased libido and improving mood. Most notably for Boomerang though, is Maca’s ability to boost energy, stamina, concentration, and endurance.


(Rhodiola rosea) aka “golden root” is an adaptogen, meaning it helps the body adapt to stress. It is often used to support exercise performance as it is shown to reduce physical and mental fatigue while increasing antioxidant activity in the body.
