~95% of clinically significant LVH in AAS users happens in the context of elevated BP, high cholesterol. or stenosis (stiff valves, a process accelerated by high BP and cholesterol).
If you get your BP and lipids into ideal range, unless you have significant stenosis, you can almost certainly reverse most if not all the LVH (how many mm?) within a year or two and still use AAS with a very low risk of it returning.
We know what it takes to get those markers into ideal range, but an aggressive preventive cardiologist will be useful for accessing those meds and monitoring your progress. You'll also have to ditch the outdated "Pharmaphobia" that many still suffer from as a result of previous generation meds that had many "off target" effects and unknown outcomes.
The good news is this is likely a "near miss" that will get you to be serious about BP and lipids, and head those risk factors off earlier in life than most of your same age peers, preventing, and reversing damage that could ultimately safe you from a heart attack or stroke down the road.
Then you'll be the "I knew a guy who did tons of drugs, Coke, opioid, even steroids, and that fucker is 100 years old, so they must not be bad for you."
