Working out for an hour and a half isn’t necessarily stupid. To discount anything simply because you disagree with it is ignorant, and this site is notorious for doing so.
It stimulates your body differently than the short workouts based soley on power movements. it encourages growth as long as the workouts have been changed up so the body doesn’t adapt to any one particular routine. The only thing you have to worry about with intensity is your glycogen levels, so carb up before and during long workouts. working with giant sets, drop sets, and supersets is going to activate the slower twitch muscles and build that coveted density as opposed to the fast twitch “size” muscles. Both are important and neither should be neglected.
you have to know the parameters as well. rest periods, types of exercises, full body vs. split, number of partners, etc. even if rest periods were relatively low, it is very possible to do even a split routine for that long without overtraining. you just have to know your body and treat it right, take the right supplements, eat the right food, and get the rest you need to maximize recovery.
in any case, gakic works when you work inside its parameters. it is one of the few supplements besides the basics that works like its supposed to. if you don’t do long workouts or you don’t get the lactic acid buildup, then it seems rather pointless to spend 70 or 80 bucks on a supplement that you won’t get any benefit from.
again, the powder tastes like dogshit but works (unless you don’t get the lactic buildup like i said earlier). pills either don’t work at all or at best still not as good as the powder.
