you got it all wrong, dude...
The part with the bottom portion is about geared lifting, but not in the manner of enhanced with PEDs, but in the manner of using a suit for the Squat, Bench and Deadlift.
Geared lifter = lifter who is using PEDs
Geared lifter = lifter who is using a suit on the SBD
It's a method so it works when you are on steroids and when you are not on steroids (ofc there are different factors like recovery that play a role but in the whole of it, it's the same).
The difference when you are benching for example is that the suit helps you with the bottom portion of the lift, so you are better off focusing on your back so you can pull the weight to you, and on your triceps, so you can lock it out. When you are a raw bencher, your chest and delts need to do more work, and your lats are more of a stabilizer, instead of a mover.
