Anyone who's done some semi serious lifting and then gone on a long break to return will know that progress is much faster the Nth time around.
This explains why those who have taken steroids will have a life long advantage:

I also understand that the male puberty imprints into the muscle development for life.
As such, two opinionated observations:
1) Once you've done steroids you should be banned from high level competitions for life, not just 4 years or what.
2) Allowing someone who has experienced and lifted weights through and after male puberty to compete against those who have not is grossly unfair to cisgendered female lifters. See point 1.
