    Exquisite product that performs precisely as advertised. Tons of resources are available from Sero on proper application so I was able to dose comfortably, no guess work. The bar is delicious and the experience it provided was enlightening and exciting. Highly recommend!!!!

    Wonderful company helping to relieve many from anxiety, depression and to find a more natural balance. I’m only speaking for myself but I am glad I found this option. They are also appreciative and communicate with thier customers on every purchase. Well done !

    This matcha star bar is pure magic. I took a few macrodoses with this and let me tell you – they all felt AMAZING. I felt like I reached expanded levels of consciousness and tapped even deeper into my authentic energy. Not to mention, it gave me all the feel-good, extra giddy, heightened vibes which helped me to just be present in my body. 10/10 would recommend.

      Incredible! Thank you so much for sharing your Star Bar experience, Lydia! Sounds like a beautiful adventure <3

    I love many of Hey Seros products. The matcha bar is one of my favourites. I love that you can micro and macro dose with this bar. I have bought it three times and will absolutely be buying it again! Hey Seros products have had a very positive impact in my life mentally and spiritually. The control of dosing is great with the star bar. I would highly recommend any of Hey Seros products.

      We LOVE to hear this! Figuring out how to dose our Star Bars was a tricky process and it means the world to know it suits you so well, Carly! Thank you for taking the time to write this kind review. ❤️ We appreciate you!

    The star bar is a great way to be introduced to mico and macro dosing, and the influence it can have on self in terms of mental health and gaining understanding. The “choose your own adventure” aspect of doses as well as additional information and tips provided makes it great to determine/guage your own comfortability and ensure a safe trip which is really nice! Flavour-wise, the matcha bar has been my fave go-to. Very smooth with subtle flavours that is very enjoyable. Overall, the positive mental and spiritual impact using sero products has had on me has been noticeable after the first couple of trips, eye-opening, and also kind…..if that makes sense ❤️ I would definitely recommend.

      Eye-opening and kind – so beautiful! Thank you for your thoughtful review, Shaelynn!

    I’ve tried all of Sero’s products & I am in love with these bars!! I love that the dosing for this bar allows you to “pick your own adventure” so to speak; with both micro-dosing & macro-dosing capabilities. Sero’s products changed my life by positively impacting my mental health & my emotional well-being since the pandemic. I am a huge fan of this company, their ethics & their formulations. This flavour is to die for if you are a matcha fan – good luck not eating the entire thing 😉

    • S E R O (verified owner)

      Your words mean so much to us, truly! Thank you Emma <3

    Been using this on and off for 6 months now. My relationship to myself has completely changed for the better and it’s reflecting in other relationships as well. I often come back to this when I need a reset. The Star Bar itself is smooth and balanced with great flavor notes. Amazing. Looking forward to the days in nature this summer!

    • S E R O (verified owner)

      This is incredible to read, Milanee. It’s amazing how when we work on ourselves, the world around us reflects back that growth. ❤️ Thank you so much for sharing. We’re grateful to be a part of your life and so happy you love Star Bar!

    I absolutely love this bar!!! It is so tasty. I take one square with a fresh cup of tea and it is such a special treat to kick start my day! Flavour is lovely, and it breaks apart perfectly. Definitely ordering again!

    • S E R O (verified owner)

      Oooo! Love this! We feel grateful that you’ve been starting your day with Sero – it sounds like a beautiful little ritual! Thanks so much for sharing. ❤️

  9. Tim (verified owner)

    This was my first purchase here. Will not be the last!

    • S E R O

      Love to hear that, Tim! ❤️ Appreciate the kind words.

  10. Galahad

    This matcha flavour is the bomb. So good. Also, the 250mg dosing per square is perfect for having a low key yet beautiful experience, and the ability to stack to greater doses is unbelievably convenient. The fact that this exists in chocolate is a game changer (especially if one needs to bring it around incognito). Phenomenal job guys!!

    • S E R O

      So happy to hear you love the matcha! It really is delicious (in our obviously bias, but honest opinion!). Also happy to hear you’ve found the dosing to be just right – it was our intention to offer something low, but buildable, so that you could experience different dosing levels. ❤️ Appreciate your kind words, Galahad!

  11. Daniel MacDonald (verified owner)

    Not only a perfect dosing method to gauge your trip, but the flavour is so delicious that it would be my go-to chocolate bar even if it didn’t have psilocybin.

    • S E R O

      We’re so glad the dosing method of Star Bar suits you well! We worked long and hard to build tasty formulations so it means a lot to hear these kind words. Thank you for sharing, Daniel! ❤️

  12. Aliya V. (verified owner)

    This bar is MAGIC! Tastes sooooo good and the dosing is great. Def recommend for people to start with one square. Can’t wait to try the other bar.

    • S E R O

      Ohhh! Our first Star Bar review! Glad to hear you love it as much as we do, Aliya. Great call on starting low and going slow. Appreciate your feedback, we look forward to hearing your thoughts on the Cacao!



Dose refers to the amount of magic mushrooms per square. 

You can also stack your squares (meaning up your dose) if you’re after a more ~magical~ trip. To learn more about the different levels macrodosing, please click here.


Note: Allow 1-2 hours for the full effects to kick in.




If you’re planning on exploring higher doses there are a few things to keep in mind:
As always, ensure you’ve got your set and setting on lock – macrodosing is a sacred experience to be treated with reverence.
After your trip, allow for proper integration with a practice such as journaling or discussing your experience with a friend.Should you feel called to explore macrodosing you can learn more about it here.

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

About Matcha

Matcha is a known for its rich antioxidant and amino-acid content, specifically L-theanine which has been shown to reduce stress. For this reason, it can be highly effective in supporting those with anxiety.

This is likely due to a trifecta of L-theanine, a major polyphenol called epigallocatechin gallate (EGCG) and caffeine. After consuming Matcha, you are able to stay focused and energized, but in a grounded and centered way.
