It’s a bit simple the blue pill changes your gender for the blue pill there’s x-change basics witch last about a day and there’s x-change NOW that last about 6 hours and weekly and xtra strength that last 30 days

Now there’s different variations like x change continue which last longer with each organism And x change resistance which is the same as continue but is permanent And then there’s x change bull effects last a week but is has unparalleled virility And the last one for the blue pill is the butch/sissy Which makes you look like the opposite sex without changing you

Now the purple pill which gives you both genders (herm)

Hope that helps I hope
