Some people might recommend strainly but be careful,if you do get from someone off there make sure you get from a company that has tons of good reviews both on strainly and other sites like reddit or forums like this. I got 2 different vials off a person with a fair amount of good reviews and it still wasn't viable.

Maybe try 7eastgenetics if you get from strainly. They are in canada but I've heard their pollen actually works.

Thanks
