Gorilla Glue 4 vs Gorilla Glue-ILGM

I see a lot of people posting about growing GG4 on the forum. Typically are they growing GG4 or GG-ILGM? Other than the breeders, could someone explain the difference between the two?

I questioned ilgm awhile back and they said gorilla glue by ilgm is very similar to gorilla glue #4


Like any thing else, I bet they sued over the name, the Gorilla glue trademark. Like girl scouts did over the cookie name.
Genetically the strains are bread from the same plants. The names have been changed to protect the innocent…
