    I have ADHD so j’ai commandé Connect four pour être plus focus. And It’s given me focus and a sense of calm. Je ne pourrais pas remplacer ma médication TDAH par Connect four, mais pour prendre une pause et être capable de me concentrer, ça le fait vraiment. I can say it has helped with focus and is also calming my anxieties. I really need that. C’est vraiment une belle option. Je le recommande. Et l’équipe de SERO est vraiment nice. Ils et elles répondent rapidement 🙂

    Works! I’ve been looking for this blend ever since I heard Paul Stamet discussing it. When a man wears a mushroom cap like that you listen close 🙂 What a happy surprise when I found the blend sold by Sero.
    CONNECT FOUR has quality ingredients. Well formulated, and with no shortcuts or junk added. I’ve been taking it for months now and feel renewed. Can focus and remember better. From my experience it is safe and effective. I trust this product and will recommend it.

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.

Lions Mane/Hericium erinaceus (315mg)

Our Lions Mane mushroom extract is a high potency dual-extract of fruiting body and mycelium. As well as the immune-enhancing beta-glucans, this extract has neurotrophic properties leading to Nerve Growth Factor (NGF) stimulation. This increases the growth and repair of neurons.

Niacin/Vitamin B3 (10mg)

Niacin is a specific type of vitamin B3 known to take GABA over the blood brain barrier with the goal of boosting neurogenesis. What’s GABA? Well it’s considered an inhibitory neurotransmitter because it blocks, or inhibits, certain brain signals and decreases activity in your nervous system.
