Ordered 20 plates + Lions Mane culture. One plate had a tiny crack in shipping. Sent a pic to Roman, he shipped two replacements the same day. Culture is absolutely ripping — already on T3.

Best pre-poured plates I’ve bought in Canada. Thick agar, zero condensation, still perfect after 2 months in the fridge. Supportive little family company — highly recommend.

Golden Oyster syringe + 10 plates. Plates poured thicker than any US vendor I’ve tried. Very satisfied!

Blue Oyster liquid culture is stupid clean. One of the owners (Roman?) replied to my silly question in 3 minutes. You don’t get that from the big guys.

Black Pearl King syringe made trunks thicker than store-bought. Hand-written thank-you note in the box — nice touch from a family shop!

Montreal ⭐⭐⭐⭐⭐
Golden Oyster LC syringe turned 10 lbs of grain - snow-white in 13 days. They threw in free alcohol wipes and some extra needles — small gesture, big appreciation.

Ordered to the rock and everything survived the trip. Lion’s Mane plates are pouring out perfect cultures. Keep doing what you’re doing, fam!

Finally found a Canadian vendor with stable genetics. Got the Grey Oysters and it’s true to type. Roman spent 20 minutes explaining isolation technique to me — way more info than I expected.

Plates are poured thick and perfect. Asked Roman which agar recipe they use — he sent me the exact ratios plus malt percentages. Made my own batch and they’re identical. 10/10 service.

Mystery syringe sale turned out to be Shitake mushrooms. Growth is insane. Roman answered all my paranoid contamination questions at 2 a.m. You guys rock.

Fast shipping, but one sleeve of plates arrived with condensation. They told me how to fix it in the fridge overnight — saved the whole batch. Customer service is unreal.
