What are the harms of having a TRT-like long cycle?

[dynamo_123]

In other words, why are test cycles usually recommended to last for just a few weeks?

If the cycle was longer, perhaps 1-2 years in the vein of a TRT-esque situation then would PCT just be stretched out more accordingly or are there other factors as to why this is one of the dumbest ideas to grace the planet?

The longer you stay on cycle the harder the recovery so your risking permanent damage staying on for 2 yrs.

personally i use steroids to put on more mass and i have found i dont continue to make gains after 8 to 10 weeks so i cycle my training and seroids so i can continue to progress.
