people cross plants, and come up with their own strains all the time.
there very well could be a local strain by some grower which was named amsterdam goo.
names are names, they mean very little... there are HUNDREDS of strains. Only the big names are important, the rest are all just mixed and matched to form new ones, which are then mixed and matched again. In my opinions... who cares?!

smoke up buddy. The stuff sounds awesome
b0n3ZA Reviewed by b0n3ZA on . Amsterdam Goo fake or real? So theres this kid in my town (About 17ish id say) selling this crazy shit its sticky the crystals fall off when you shake it its like a neon green color and I must admit it fucked my day UP! But the only thing shady about him is its name... he calls it "Amsterdam Goo" Its some straight dank ass fire but the name is a little fishy imo... The price is 25/g or 70/8th so is this a real strain or is he just getting some dank dro and naming it what he wants to? Rating: 5
