Fusion Mushroom Chocolate Bars UK

Fusion Chocolate Bars carry the heaviest per-bar load on the UK Shroom Bros shelf — 6g of active psilocybin per bar, 12 squares at 0.5g each.

What's inside Fusion Chocolate Bars

UK Shroom Bros stocks the rotating Fusion Chocolate Bars line-up: Dark Chocolate, Milk Chocolate, Cookies & Cream, Mint. Stock turns fast — if a flavour is sold out, check back within 5–7 days as we restock weekly direct from the brand. Every batch lands in the warehouse already lab-verified for psilocybin content and dose uniformity (±10% per unit).

How to dose Fusion Chocolate Bars

Start with the smallest unit — one square, one gummy or one lozenge — and wait the full 60-to-90-minute onset window before considering a redose. The most-common mistake new users make is redosing at the 30-minute mark before the active has fully kicked in, which doubles the eventual peak. If you are new to psilocybin entirely, read our microdosing beginners guide first and start with a sub-perceptual dose for your first two or three sessions.

A note on UK legality and harm reduction

Psilocybin and psilocin are Class A controlled substances under the UK Misuse of Drugs Act 1971. UK Shroom Bros operates discreetly within UK postal channels and customers are responsible for compliance in their own jurisdiction. Anyone with a personal or family history of psychosis, bipolar disorder or schizophrenia should not use psychedelic doses, and anyone taking SSRIs, MAOIs, lithium or tramadol should consult a pharmacist before any psilocybin dose. Never combine psilocybin with alcohol or stimulants, and never drive under the influence.
