@NYOBUNKNOWED We have plenty of trainers available here: https://www.gta5-mods.com/scripts/tags/trainer. If you're talking about a multiplayer mod menu, that's against our upload and forums policies.
This. Rockstar sends out C&Ds to whoever violates their terms of service (One map maker for FiveReborn, a multiplayer mod for GTA 5 got a Cease and Desist from Rockstar. Thus, he was forced to stop making maps.)
Likewise single player mods are fine, just stay out of Online.
