It means a group of us started lifting in school, same weight, skinny dudes, some took creatine, and put on a lot of muscle quick, but got no stronger, we lifted the same amounts, they weren’t better at our other gym activities either.
Sounds like they were retaining more water rather than quickly putting on a lot of muscle, which is common with creatine usage. I explained what actually happens in another reply.
