72-99 Str in a month? Bandits?

Lol I could get a 99 from 70 via slayer non-no lifing within 1 1/2 - 2 months.

If I no lifed it constantly it'd take me like a month via pc.

He so could get 99 str in a month at bandits...Because if he were doing it the bandit way, he'd probably just leave it on all day and night - which means he'd probably get to 99 within a few weeks.
You'd get a random and die though, most probably.
And as Matty said, even doing it on slayer it wouldnt take longer than a few months.

What lvl are bandits and where can you find them.
