Ammo being given to players upon spawn

I get the feeling this is related to the fact that I recently installed ULX on my server, but whenever players spawn in it seems that they get 9999 ammo in the AR2, SMG and shotgun ammo sections. Is this something ULX does or is it a Gmod command? I’m running Nutscript 1.1 on a custom schema.

I never used NS before, you should look through the whole code, to look for the “PlayerSpawn” Hook, and look inside of the function, if the ammo is given, if not, maybe some addon of you got an backdoor.
