My brother has had "problems". He's on some prescription meds, but he's also had other stuff lying around in the past.

I found 3 pills with the following description:
- Round
- White
- "G" imprinted on one side
- What looks like "L" over "10" on other, possibly "1" over "10", or maybe upside down it's "OL" over "7"
- Not scored

I've seen many pills in my day, but never this. Given his history, I worry it might be an amphetamine, or even Ecstasy.

Any help would be appreciated!
