Thanks for your quick replies Christian and for providing the link to your other article, which I am going to read with interest now.
I apologize if I have misinterpreted your posts from October 2016 from this thread: Strength Requisite for Natty's? ("Best Damn Workout..."?) - #8 by Christian_Thibaudeau. You did say in there that you were at that point mixing 5/3/1 main lifts with assistance work following the Best Damn techniques and then in another post there you said that you did this 4x per week with another 2 trainings in a week (one covering olympic lifts and the other one hypertrophy). So, my, ‘idiotic’ brain put these two things together and I have wrongly assumed that you were doing 5/3/1 for main lifts, complemented with Best Damn for the assistance, while doing 6 trainings per week. But now you are saying that you personally could not do it, so forget it. 
Anyway, I didn’t mean to spread any false information whatsoever.
I also apologize for being imprecise with the used wording in my original post - I didn’t assume that you would be doing boring but big with 5/3/1 lifts, it was just me “thinking out loud” on what would likely be an overkill in terms of the volume (mixed with best damn for the rest of the workout and with 6 workouts per week). No need to immediately jump on me and get mad, use expressive words, etc.
To me, the real added value of this forum is to correct misinterpretations and false thinking - I hope that you agree that it is always better to ask when unsure than not ask and then do some stupid shit in the gym (and life). However, your rather direct/aggressive answers may put many people off from actually even asking. Anyway, you’ve got to do what you’ve got to do and as I said above, I highly appreciate, value and respect all your work, your results and knowledge. You are one of the best publishing coaches I have had a privilege to read (and now exchange few messages with). Peace.
