Can u build a tolerance to Letro?

[hulk0427]

I have been doing a blast and cruise for about 6 months now. Im prone to gyno so I always use letro. I was wondering if using it for long periods of time can you build a tolerance to it?
I know letro is the most powerful anti-e killing about 98% of estrogen in your body, but is it as effective on day one as it will be 6 months from now?

I have been doing a blast and cruise for about 6 months now. Im prone to gynecomastia so I always use Femera - letrozole - . I was wondering if using it for long periods of time can you build a tolerance to it?
I know Femera - letrozole - is the most powerful anti-e killing about 98% of estrogen in your body, but is it as effective on day one as it will be 6 months from now?

Well by how much? I mean will it go from knocking out 98% to just 90% or will it jump to like 50% estro down, you know what I mean?
