Need some help finding out what this is.

Just a little bit ago I requested valium from one of my dealers. He said he could help me out. So today I go up to his house and he's telling me he's got some really cheap pills that will do the same for 1$ a pop. I was wondering if you guys could help me out if you know what they are? Its a round white pill with F|L on one side and 10 on the other. I'll post pics later if needed. I just thought it was kind of shady of him to not tell me the exact name...
