I never was a fan of going beyond failure or doing forced reps, it seems like it caused myself and others i trained with more nagging pains and injuries to the joints. I used to rupture fibers in my triceps doing forced reps with dips, skull crushers and bench presses. I think HIT is a good protocol for certain people, but I can't say I'd recommend it to the average lifter. I would think a more advanced lifter would benefit from it more as they already know their body and need help breaking through the next barrier, so to speak.
What i used many years ago that was similar to HIT, was Max-OT. It was a bunch of "assimilation" sets and then 2-3 very intense sets to positive failure in a low rep range. It actually worked very well for me and a few other people I introduced it to. The only thing I retained from it that I still do today are the assimilation sets; I'll do 3-4 slow controlled warm up sets that are only 3-4 reps while increasing weight, just to let my body get used to a new load, but not tax the muscles. I mainly do this on compound movements like presses, rows, squats, etc. not really needed for cable flyes and stuff like that IMO. What this does for me is warm up while keeping a ton of energy left in the tank, so I can do 4-5 working sets with more intensity, which is important because that is where you want the energy to spend.
To answer your question, I would never recommend HIT unless someone needed it to break past a plateau. I just never found it to work for myself or anyone else, juiced or natural didn't matter. I've been training seriously for about 20 years now and volume is king, the biggest I've ever been was when i was training high volume in the 10-15 rep range, up to 5 working sets per movement. I was in the best shape of my life benching 275 for sets of 12 instead of pressing high 300's for a few reps in years past. I think training heavy helped build my base, but the last 6 years or so i haven't even once tried to do less than 5 reps or go past positive failure, mainly due to training alone and having a ton of nagging injuries. I look more like a bodybuilder from to 60-70's and that's what i wanted, i stay around 10-12% BF and rarely get over 210 pounds at 5'11".
Now i don't think training for a "pump" is the answer, but i believe there is a happy medium between volume and overload, you need both to an extent. Even doing high volume I train with intensity and push near failure, but i don't really go beyond what i can do with good form. I've been using AAS for over 10 years, so that may factor into it to some extend, but I don't use much more than TRT doses these days and I'm built better than I was 8 years ago using high doses.
