okay kiddies chill with the seeds for a sec, you can buy them from the store but they have pesticides on them which can make you VERY VERY ILL trust me I've done it and it was the worst trip of my LIFE I'd suggest using the ones your friend has, and don't eat 300-500, crush them up in a coffee grinder and weigh out(with a digital scale) 7-10 grams, do not ingest over 25 grams(I saw the tox reports when I was in the hospital), that is the lethal dosage, I was in the hospital for 18 grams, so I suggest not to do more than that. I was seizing uncontrollably for about 5 minutes, not a fun experience. Umm I reccomend getting a very very sweet drink and once the seeds are compltely powder mix them with the drink(something like really strong kool-aid)

If you don't start to trip after an hour or so, try taking a walk around the block to get your blood moving, sometimes that helps. be careful with any hallucinogen

oh and its not that much money at some garden stores, it cost me 5 dollars to get 18 grams of seeds
