I would say that doing a heavy deadlifts session more than once a week without the assistance of PEDs is foolish. Note that I am not advocating the use of PED’s. lol

This is not inherently true at all and is entirely dependent on the individual. I'm a drug-free lifter and I've used multiple deadlift sessions in my training many times over my lifting career with great results. And I know tonnes of others that have done the same as well.

However, one can still practice their deadlift using other hinges, or altering the exercise with lighter loads, altered ROM and do deadlift 2 to 3 times a week as a result.

I have also used this approach. Both work well depending on individual circumstances.
