What treatment changes

What it does, and when

No before-and-after photographs, because they prove nothing about hormones. What follows is the timeline the research supports and the honest limits on it.

If treatment is indicated, the usual order
3 to 4 weeksSexual interest and morning erections. The earliest thing to move.
6 weeksMood and irritability. Often the change other people notice first.
3 monthsEnergy through the afternoon. Red cell count rises, which is why we recheck it.
3 to 6 monthsStrength, if you are training. Testosterone does not lift the weight for you.
6 to 12 monthsBody composition. Fat down, lean mass up, slowly and not dramatically.
12 months and beyondBone density. Real, measurable, and the least visible thing on this list.

What it will not do

It will not make you younger. It corrects a deficiency, and that is a different claim.

It will not fix a problem that was never hormonal. If your testosterone is normal, low testosterone is not what is wrong, and treating it anyway wastes a year.

It will not replace sleep, food or training. Men who fix those alongside treatment do markedly better than men who do not.

It will not preserve your fertility. Testosterone suppresses sperm production. If you want children, say so before we start -- there are other routes, and enclomiphene is one of them.

It is not a weight loss drug. Body composition shifts. The scale often does not.

The honest part

Roughly a third of men who come in convinced they need testosterone do not have low testosterone. Two morning draws is how we find that out. Being told no is a result, and it is cheaper than a year of treatment that was never going to work.
