help me find a shrinking potion (reno nv)

i’m looking for a real working way to shrink. i know its very strange, but i’m serious, and i know that there must really be a way. i would like to shrink myself to 3 inches tall. no joke. lol. i’m a 24 year old male. i’d do anything, anything to get a hold of something that really honestly works. thank you!
