Larry had a newsletter back in the 80's-90's. Some of the best info I've ever seen on training were in those newsletters.
He also had an excellent protein, and also sold some equipment like his Scott-Bench, etc.
His protein was really good for the times, no bloat (no lactose) and tasted amazing...
(He modeled it after Blairs (He called it Hyper-Growth). I see it still being sold, but probably different and mass produced.
I think the 3 best proteins I've had are his, Drapers and Dr. Squats (Hatfield).
Just seemed to be of higher quality for some reason... (Again, no bloat)..
They didnt seem to have all the artificial stuff (or as much) and had the enzymes added to fight lactose...
