Steriods will give you a massive physical advantage too. If you're not doing something with a governing body and get them prescribed you're golden.
If you have enough your own testosterone then doing TRT is more harm than good. But once you get older and don’t anymore - TRT is golden.
This is actually another growing problem: TRT clinics will prescribe testosterone to virtually anyone who requests it. Among new TRT patients, a large number of them didn't even have bloodwork drawn before receiving their first prescription.
Many of the TRT clinics also hide the fact that going on TRT results in testicular atrophy and lifelong dependence. The forums and Reddits are full of people who decided that injecting testosterone every couple days for the rest of their life isn't all it's cracked up to be are realizing that it's not so simple for everyone to get off of it, even with all the HCG, SERMs, and PCT in the world.
