Its likely a bit of a coin toss what effects you get. If for some reason you're getting good aromatase activation, then extra T might convert into estrogens. But only way to really know is to try because of individual differences.

Another way is to train harder, age and lower T and HGH levels will cause your muscles athropy and exercise results come slower. I have never been "good" at building muscle, but I've had times of very rigorous exercise so I know the difference from T dominance (likely natuarlly low T though.) to fully female balance while on HRT. Diffference in strength seems to be liks 70% compared to before and endurance like 50%, to me endurance drop has been more significant than strength.

So perhaps add heavier or specific arm exercises if muscle definition is what you want? Do it body building style so that you maximise your chances of building muscle mass instead of just strength or endurance. And then try T boost? what do you have to lose to find out how it works for you?

Bad idea.
All lifting weights will do is raise cortisol (the stress hormone) levels, which will only speed up the aging of your body, reduce lifespan, and generally stress you out.
It won't raise T in any provable way.

Just like the best way to raise E is to eat ovaries, the best way to raise T is to eat testicles.
