What Hans said. I started competing in powerlifting (raw division) in 2012 at age 62. I've never used a squat suit to lift in nor even knee sleeves, although it's within the rules in the raw division. What I have seen are the poor unfortunate souls struggling to get into their squat suits and get them secured. Most of them needed 1-2 helpers, and it was a sweaty, red faced battle that couldn't help but remind me of the sculpture of Laocoön and His Sons getting enwrapped by serpents.

Equipped and raw are indeed two different beasts. Never having used "gear" of any kind, including drugs,
I'd be surprised if lifting equipped did anything for raw lifts.
