Good morning or evening depending on your time zone.

I have just started training again and I was curious what tips my brother's may have in regards to making fast gains? (With out illegal supplements)

Also what foods should I be eating that will yield the best results?

Last but not least. What is the best system for gaining muscle mass. Heavy weights low reps or lower weights and higher reps?

Any and all input is welcome.

Have a great day and let's keep strong.
