The whole point of those supplements is to increase T and control E, the same objectives of TRT if done right.
450 is not low by TRT standards. If the androgel is effective it will shutdown your HPTA and might produce T levels near where you are now. And if E2 is not controlled, you could feel worse. The outcome depends on how much androgel was prescribed. 5gr/day may not make you any better. And some simply do not respond to transdermals at all.
There is a need to do TRT right and TRT without E2 control is often the road to poor results.
At your age, you do not want shrinking testicles and a real risk of infertility. To avoid that, you would need to inject 250iu hCG SC EOD. Applying a transdermal T product to avoid injections, then injecting hCG to save you testicles is silly. To do TRT and keep your testes healthy, you need to inject hCG and then injecting testosterone makes more sense than a transdermal.
I am not trying to drive your decision either way. You need to understand that you need T+AI+hCG if you do TRT at all.
You can try the supplements and use them as long as you feel that they are of benefit. Meanwhile, you can keep reading and understanding the issues, and start getting aware of what doctors in your area might be able to do TRT right.
And of note, most TRT docs will not start you on TRT at TT=450 unless your FT is very low or you have some strong symptoms of T level problems.
