A 5-pack is the simplest way to start a comparison: five different strains, one slide set each. A typical first set pairs two classic references (Golden Teacher and B+) with three Penis Envy family strains, so you can compare spore size, shape and colour between a heavy-spored strain and the PE family’s sparser deposits.
How to order
Choose 5 different spore syringes from the list below and write your choices in the order notes at checkout. If you don’t pick, you’ll receive a house selection. Every syringe is 10cc of sterile water with spores scraped from a spore print, prepared in our Ottawa lab under 99.99% HEPA-filtered laminar flow, for microscopy and taxonomy research only.

Working through a 5-strain set
Label each slide with the strain and date, resuspend each syringe before use, and measure at least 20 spores per strain with a calibrated reticle (How to use a spore syringe). Keep the syringes you aren’t using sealed in the main part of the fridge (storage guide).





Good quality, well packaged, good service, good price, what more can you want?
Super fast and well informed transaction. Actually arrived a day earlier than expected. Great to deal with and great products, tip top quality. Next purchase is days away!
I have ordered the 3 syringe pack from Sporesworldwide twice, and I’ve had great results from both orders so far. Sil is quick to respond to my questions and when there was a shipping delay (not his faults, covid and Canada Post) on the first order he offered a refund of the shipping cost. I would recommend his syringes, no issues so far and can’t beat the price
