Terms & Conditions.

1. Who we are and how to reach us

This website is run by Mylocybe, a partnership registered in Scotland, trading as Cylocybe. Throughout this page, “we”, “us” and “our” mean Cylocybe, and “our site” or “the site” means this website.

The best way to contact us is through our contact form. If we need to reach you, depending on the type of account you have, we will either write to the email address you gave us with your order, send you a message within your Cylocybe account or send you a Signal message if you have it linked to your account.

2. This agreement covers two things

One, using the website itself. Two, buying products from us. By visiting the site you accept these terms. If you place an order, you also accept the purchase terms further down. If you do not agree with any of it, please do not use the site.

It is worth keeping a copy of this page for your records. We may update these terms now and then (for example, to reflect changes in our services, in how people use the site, or in the law), so it is a good idea to glance at it each time you use the site. The date it last changed is at the bottom. If you think there is a mistake in these terms, please tell us so we can sort it out.

A few related policies sit alongside this agreement and form part of it: our Privacy Policy (how we handle your personal data), our Cookie Policy (how we use cookies), and the rules on acceptable behaviour set out in section 4 below. We will only ever use your personal information in line with our Privacy Policy.

3. Are you a consumer or a business?

Some of your rights depend on which one you are, so it matters.

You are a consumer if you are an individual buying mainly for personal use, not for your trade, business, craft or profession. As a consumer, our site is for your private, domestic use only, and you agree not to use our products for commercial, business or resale purposes.

If you are a business customer, this agreement is the entire agreement between us about your purchase. You confirm you have not relied on any statement, promise, representation, assurance or warranty that is not written here. The rules that apply only to business customers are in section 14.

4. Using the site responsibly

You may use the site only for lawful purposes. Please do not:

• Use it in any way that breaks any law or regulation, or that is unlawful or fraudulent in any way.
• Try to harm anyone, or harass, upset, embarrass, alarm or annoy anyone.
• Send spam (unsolicited or unauthorised advertising or promotional material).
• Knowingly send, receive, upload, download or reuse any material that does not meet the content standards below.
• Knowingly send or upload anything containing viruses, trojans, worms, time-bombs, keystroke loggers, spyware, adware or any other harmful or malicious code.
• Access without permission, interfere with, damage or disrupt any part of the site, the servers and networks it runs on, the software behind it, or any equipment, network or software belonging to anyone else.
• Reproduce, duplicate, copy or resell any part of the site except as the intellectual property rules in section 6 allow.

You are responsible for making sure anyone who uses the site through your internet connection knows about these terms and follows them.

If you post or contribute anything

From time to time we may offer interactive features, such as commenting on products, joining our blog, or live chat with our team. Where we do, we will tell you clearly what the feature is and whether (and how) it is moderated, for example whether moderation is by a person or done technically. We are not obliged to monitor or moderate these features, and we are not liable for loss caused by someone misusing them against these rules, whether the feature is moderated or not.

Anything you contribute must follow these content standards, in spirit as well as to the letter. We decide, at our discretion, whether a contribution breaks them. A contribution must be accurate where it states facts, genuinely held where it states opinions, and lawful in Scotland and in any country it is posted from. It must not:

• Be defamatory of anyone, or obscene, offensive, hateful, inflammatory or sexually explicit.
• Promote violence, or discrimination based on race, sex, religion, nationality, disability, sexual orientation or age.
• Infringe anyone’s intellectual property, or breach a legal duty owed to someone else (such as a duty of confidence or a contract).
• Promote any illegal activity, or advocate, incite or help anyone commit an unlawful act such as copyright infringement or computer misuse.
• Be in contempt of court, threatening, abusive, invasive of someone’s privacy, or likely to cause needless annoyance, inconvenience or anxiety.
• Impersonate anyone, misrepresent who you are or who you are connected with, or give the false impression that it comes from Cylocybe.

If you break these rules

If we decide you have broken the rules in this section, we may take whatever action we reasonably think is right. That can include warning you, removing your contributions, suspending or permanently withdrawing your right to use the site, taking legal action, and passing relevant information to law enforcement where we reasonably need to or the law requires it. We are not liable for the actions we take in response to a breach, and we are not limited to the steps listed here.

5. Your account and security

If we give you a username, password or other security details, keep them confidential and do not share them with anyone. If you think someone has accessed your account without permission, tell us straight away through the contact form. We can disable any account or password at any time if we believe you have not followed these terms.

6. Availability, content and other people’s sites

The site is free to use. We do our best to keep it running, but we cannot promise it will always be available without interruption. We may suspend, withdraw or restrict access to all or part of it for operational or business reasons, and we will give reasonable notice where we can.

Everything on the site (text, images, design and other content) is owned by us or licensed to us, and protected by copyright worldwide. You may print or download extracts for your own personal use and share them within your organisation, as long as you do not change them and do not pull graphics, images or media out of their accompanying text. You must not use any of our content for commercial purposes without a licence from us or our licensors. Unauthorised use ends your right to use the site immediately, and you must destroy or return any copies if we ask.

The information on the site is for general guidance only and is not professional advice. Nothing here is medical, legal or financial advice. We work to keep it accurate and current, but we make no promises about its completeness, accuracy or reliability, so please do not rely on it as advice.

The site may link to other websites. Those links are there for convenience and are not an endorsement. We are not responsible for the content or availability of any site we do not run. We may also use third-party services (for example, YouTube API Services) to provide certain features. If you use those features, you also agree to the relevant third-party terms, including the YouTube Terms of Service and the Google Privacy Policy.

Linking to us

You may link to our home page in a fair and lawful way, as long as it does not damage our reputation or suggest an association or endorsement that does not exist. Please do not frame our site within another, or link to any page other than the home page, without our written permission first. We can withdraw permission to link at any time without notice.

7. Who can buy, and staying on the right side of the law

You must be at least 18 years old to buy from Cylocybe.

Here is the honest legal position, because it matters. In the UK it is illegal to cultivate, possess or supply mushrooms containing psilocybin. Psilocybin and psychedelic mushrooms are controlled under the Misuse of Drugs Act 1971. Our magic mushroom spore products are sold strictly for legitimate purposes such as microscopy, research and collecting, and they are lawful because a dormant spore contains no controlled substance. They are not sold as a way to grow anything, and must never be used to cultivate a psilocybin-containing species. Our gourmet (edible) mushroom supplies are for growing legal, non-psychoactive species.

It is your job to check the law where you place the order and where it is being delivered, so that buying, possessing or using our products does not break any law or regulation. By ordering, you promise that:

• You will not use our products for anything illegal, including growing any species that contains psilocybin.
• It is lawful for you to buy and possess our products where you are, and lawful for the recipient to receive them at the destination.

If you break that promise, we may end our contract with you. We can also refuse or cancel any order we believe may be used for an illegal purpose, and we may close any account that tries to involve us in unlawful activity. We will never advise you to break the law.

8. Ordering and our contract with you

How an order becomes a contract

You can place your order online. We will acknowledge your order by email. The contract is formed when we email to confirm acceptance and that your order has been dispatched to the address you gave us. We will give you an order number in that email, so please quote it whenever you get in touch about your order. If we cannot accept your order, we will tell you in writing and you will not be charged.

Changing an order

If you want to change something before dispatch, contact us as soon as you can. We will tell you whether the change is possible, flag any effect on price or timing, and ask you to confirm before we go ahead.

If we need information from you

If we need details from you to deliver your order and you do not provide them within a reasonable time, we may cancel the contract and deduct our reasonable costs.

Changes to products

We may change a product to keep up with the law or regulatory requirements, or to make minor technical tweaks and improvements. We do not expect these changes to affect how you use or enjoy the product.

9. Our products, prices and payment

• Appearance. Products may look slightly different from their photos. Images are illustrative, and colours can vary by screen or device.
• Packaging. Packaging may differ from what is shown, depending on the product.
• Measurements. Sizes, weights, capacities and dimensions carry the small tolerance the law allows, so please treat them as a guide rather than an exact figure.
• Prices. The price of a product is the price shown on the order pages when you place your order, and prices can change from time to time. Prices do not include delivery, which is shown separately at checkout. We take reasonable care to get prices right, but if we spot a pricing error we will contact you before accepting your order for instructions, or cancel the order if we cannot reach you.
• Payment. We accept payment by bank transfer, Proton Wallet and cash in post. Some methods may not always be available, and the options open to you are shown at checkout. If you are a business customer, you must pay all amounts in full without any set-off, counterclaim, deduction or withholding, except any tax you have to deduct by law.

10. Delivery

Delivery costs are shown on the site and at checkout, and we will tell you during the order process when we expect to get your products to you. Delivery is complete and the products become your responsibility when the courier delivers them to your provided address or you, or someone acting for you, collect them from a specified delivery point. You have full ownership of the products at this point.

If nobody is at your delivery address to accept the parcel, the courier may leave it in a safe place, with a neighbour or leave a note with redelivery instructions, depending on the service used. If you do not rearrange delivery or collect from a delivery point/depot as instructed, the parcel will be returned to us by the courier. At the point we receive the parcel back, we will contact you to discuss how you would like to proceed. You are responsible for any fees applied by the courier and further delivery costs, should you request the parcel to be sent out again.

If a delay is caused by something outside our control, we will let you know and do what we reasonably can to keep it short (see section 15). If we miss a delivery deadline we agreed, you can cancel if we have refused to deliver, or if you told us before we accepted the order that delivery by that date was essential. Otherwise you can set a reasonable new deadline and cancel if we miss that too.

International delivery

We deliver worldwide. The shipping options for your country appear at checkout once you enter your address. International orders may attract import duties, taxes and administration charges at the destination, which we cannot control or predict. Those charges are the recipient’s responsibility, so please check with your local customs office before ordering. You must comply with the laws of the UK, the country you order from, and the destination country, and we are not responsible if you break any of them. If you choose a delivery method where risk passes to you when the goods are handed to the international carrier, the goods travel at your risk from that point.

11. If you change your mind (your right to cancel)

As a consumer, you have a legal right to change your mind. You can cancel within 14 days of receiving the goods, and your cancellation takes effect on the day you send it. Just tell us through the contact form, including your name and order details, and we will acknowledge it. Where an order is delivered in one go, the 14 days run from the day you receive the goods; if items arrive on different days, they run from the day you receive the last item.

If you cancel because you have changed your mind and the item is eligible, we will refund the price you paid plus delivery, calculated at the least expensive delivery method we offer (so if you paid for a premium option, we refund the standard cost, not the extra). You must send the goods back within 14 calendar days of telling us, and you pay the cost of return postage. We can reduce your refund to reflect any drop in value caused by handling the goods more than you would need to check what they are and how they work. We process the refund after we receive the return, back to the payment method you used.

The right to change your mind does not apply to everything. It does not cover products made fresh to order, products sealed for contamination protection once you have unsealed them, or any item with a broken or removed seal. In particular, it does not apply to spore products or grow kits (see below).

Returns on specific products

Because of what they are, some products have their own rules. Before sending anything back, email us your order number and a short description of the issue, and wait for us to confirm the next steps. Returns and replacements are at our discretion. Please do not return spore products or grow kits unless we explicitly ask you to.

• Spore products are sold for microscopy and genetic preservation only. For safety and quality reasons we do not accept returns of spore products and we do not refund them. Where there is a problem, we handle it by replacement or resend at our discretion.
• Psilocybe cubensis spores (syringes, prints, swabs, vials) are guaranteed for authenticity and viability for that purpose. If you believe a product does not meet that standard, you can ask for a replacement at our discretion within 6 weeks (42 days) of dispatch.
• Other (wild-sourced) spore species. Many species are wild sourced (unlike lab-produced species such as Psilocybe cubensis) and can contain natural hitchhikers, so for these we offer no replacements, no refunds and no returns.
• Liquid culture syringes are for gourmet cultivation and guaranteed for viability and authenticity for that purpose. They are handled by replacement only, at our discretion, within 3 weeks (21 days) of dispatch. Refunds are not offered on them.
• Grow kits are perishable and cannot be resold. Once used they cannot be replaced or refunded, and we do not offer refunds on grow kits. If you notice an issue before use, contact us straight away.

12. If something is wrong with your order

Nothing in these terms affects your legal rights. If a product is faulty, not as described, damaged in transit, or the wrong item, you have a legal right to reject it. Please tell us within 72 hours of delivery through the contact form. Depending on the situation, we will refund the price you paid, the delivery charges and reasonable return costs, or repair or replace the item, as appropriate. We process refunds or replacements after we have received and inspected any returned goods, using the method we have confirmed with you, and refunds go back to the payment method you used.

For change-of-mind cancellations you cover return postage. In other cases the customer generally pays return shipping unless we confirm otherwise in writing, but where an item arrives damaged or is not as ordered, we will confirm whether we are sending a prepaid label or reimbursing reasonable return costs. If you are returning something from outside the UK, you are responsible for any customs duties or tariffs on the return unless we agree otherwise in writing.

13. Our responsibility to you as a consumer

We do not exclude or limit our liability to you in any way where it would be unlawful to do so. That includes liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for breach of your legal rights as a consumer, and for defective products under the Consumer Protection Act 1987.

We are responsible for loss or damage you suffer that is a foreseeable result of us breaking this agreement or failing to use reasonable care and skill. Loss or damage is foreseeable if it is obvious that it will happen, or if, when the contract was made, both we and you knew it might happen. We are not responsible for loss or damage that is not foreseeable.

Some products carry warnings about how, and by whom, they should be used. We are not responsible for loss or damage caused by ignoring a warning that is reasonably obvious on examination. As a consumer you agree not to use our products for commercial, business or resale purposes, and we are not liable for any business losses.

The information and content on the site is for general use, not for any specific purpose you might rely on it for. It is not medical, legal or financial advice. Always get proper professional advice before doing or not doing something based on what you read here.

14. If you are a business customer

This section applies only if you are buying as a business.

We warrant that, on delivery and for one month afterwards, the goods will match their description and any relevant specification in all material respects, be free from material defects in design, materials and workmanship, be of satisfactory quality, and be fit for any purpose we have stated. If you tell us within a reasonable time, give us a fair chance to examine the goods, and return them at our cost when asked, we will (at our option) repair them, replace them, or refund the price. This warranty does not apply if you keep using the goods after telling us about a defect, do not follow our instructions, alter or repair them without our written consent, or where the problem comes from fair wear and tear, wilful damage, negligence or abnormal storage.

To the fullest extent the law allows, all terms, warranties and conditions implied by statute or common law are excluded. We are not liable to you for loss of profit, or for any indirect or consequential loss. Our total liability to you for any loss or damage arising under or in connection with the contract, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the greater of GBP 100 and 100 percent of the net amount you paid for the products in question. None of this affects our liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for breach of the title guarantees, for defective products under the Consumer Protection Act 1987, or for anything else that cannot lawfully be limited.

15. Events outside our control

Sometimes things happen that no one can reasonably control. If an event like that stops us doing what we agreed, we are not responsible for the delay, but we will contact you as soon as we can and do what we reasonably can to reduce it. If there is a risk of substantial delay, you can contact us to end the affected order and get a refund for anything you have paid for but not received.

16. Ending the contract

We may end the contract by writing to you if you break it in a serious way, for example by not paying when payment is due, by not giving us information we reasonably need to fulfil the order, or by breaking the promises about lawful use in section 7. If we end the contract for one of those reasons, we may keep or charge reasonable compensation for the net costs we lose as a result. If we need information from you to deliver a product and you do not provide it within a reasonable time, we may cancel the contract and deduct our reasonable costs.

17. Complaints, and the law that applies

If something goes wrong, please tell us first through the contact form so we can try to put it right. We take complaints seriously and will do our best to sort things out quickly and fairly.

If you are a consumer, these terms are governed by Scots law. You can bring proceedings in the Scottish courts, and depending on where you live in the UK you may also be able to bring proceedings in England and Wales or in Northern Ireland. If you are a business, these terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.

18. If you are outside the EU

This section applies only if you are located outside the European Union. Everything else on this page still applies to you. If you cancel an eligible order, refunds follow the consumer rules above, except that we cannot refund postage or packaging, or any import duties, taxes or administration fees incurred on delivery or return. If we later find a product was not returned, or came back damaged, you must pay us an appropriate amount. Refunds go back to the original payment method. If you receive a faulty, misdescribed or wrong product, we will refund the full price, the delivery charges you paid and reasonable return costs, or repair or replace it, as appropriate.

19. A few legal odds and ends

• We may transfer this agreement. We can transfer our rights and obligations under it to another organisation. This will not affect your rights.
• You need our consent to transfer your rights. You can only pass your rights or obligations under this agreement to someone else if we agree in writing.
• No third-party rights. This agreement is between you and us. No one else has any right to enforce it.
• If part of it does not hold up. Each paragraph stands on its own. If a court decides any part of this agreement is unlawful, the rest of it keeps working.
• Not enforcing something is not giving it up. If we delay in enforcing any part of this agreement, that does not stop us enforcing it later.
