This is a modified version of the 4 day advanced medium load Sheiko program with more reps in the 70-80% 1RM range and a greater focus on hypertrophy. There is a little more volume overall as well.
Here is the description from the Sheiko forum:
“Here is my Roberts Hypertrophy Program modified for more hypertrophy emphasis. I currently do something just like this and enjoy it very much. That said, I know people that this would be terrible for. Mainly because they are strong and have bad form.
It’s still pretty much the same but there are more lifts between 70-80% for the main lifts and more additional lift volume. Special exercises are left alone so they do what they are supposed to do without interference. 85% and above are left alone too. Reps go high enough to trigger a stronger metabolic response but not too high as to degrade form excessively and lengthen recovery. So it’s not a dedicated hypertrophy program, just one with an added hypertrophy emphasis” – Robert Frederick, Sheiko Forums
You can find the original version of the advanced medium load Sheiko program in the Sheiko program spreadsheet collection.
