Use the typical 5/3/1, BBB with FSL and follow the basic assistance guidelines - do this for 6 weeks.
After 6 weeks, do the PR sets, with 5x5 FSL and again, the basic assistance guidelines.
However, all of this is moot unless you are eating to gain, which I have found only a small (single digits) percentage seem to do. So eat red meat, eggs, milk if tolerable, potatoes, rice and fruit/vegetables. Try to get at least your bodyweight in whole food protein.
Your diet will make/break you unless you are a physical freak.
And when did getting bigger become removed from being stronger? Holy shit -you guys must stop reading the internet because it seems 99% of the shit you read sucks. Really sucks.
