We guarantee 100% sterility for spore and culture products within 30 days of purchase, as long as items remain unused for a full refund.

While we maintain a strong track record, spores can't be made entirely sterile due to their nature. If you have quality concerns, email us at within seven days of receiving your order. Please avoid removing the syringe from its packaging until we assist you. We'll promptly replace it if needed and may provide a return label.

We're dedicated to top-tier microscopy specimens and happy to replace spore syringes for your satisfaction.

Do not contact us about cultivating P. Cubensis spores; they're for microscopy and taxonomic use only. Mentioning cultivation will cancel your order.

We primarily use white mailer boxes for USPS shipping. If your items arrive damaged, email a clear photo within 7 days, and we'll send a replacement within 24 hours.

Ensure accurate address info; we're not responsible for incorrect addresses. We provide tracking but can't cover lost or stolen packages.

If you're unsatisfied or made a research mistake, email us for a special replacement discount.
