How to Read Your Testosterone Labs (TRT or Restore Your Own?)

How to Read Your Testosterone Labs Before You Start TRT

Low testosterone on a lab report tells you almost nothing on its own, because the number that matters is what your brain is doing about it. Two men can walk in with the same total test of 340 and need completely opposite treatment. The difference shows up in two hormones most people never look at.

If you are in a position where you want to introduce drugs, TRT is the one thing that you can't do to come off of. Once you put exogenous testosterone in, your brain stops sending the signal to make your own, your testicles shrink from disuse, and restarting that system afterward is slow and often incomplete. So the order of operations matters more than almost anything else here.

Start with the whole chain, because the lab panel only makes sense if you know what it is measuring.

Your hypothalamus releases a pulse of something called GnRH, which is the starting signal for the whole system. That hits your pituitary, a gland at the base of your brain, and the pituitary responds by releasing LH and FSH into your blood. Those travel down to your testicles, where LH tells the Leydig cells to make testosterone and FSH handles sperm production. Then testosterone comes back up and tells the brain to ease off, which is why the whole thing runs as a loop and not a one-way street.

So a lot of times the first thing that we have to figure out with your labs in order to find out what the best approach for you is, we have to look at your LH, your FSH, your total test, your free test, your SHBG. If I look at your labs and your LH and FSH are normal or even high, but your testosterone is low, most of the time that's an indication that your testicles just aren't able to produce the testosterone that your body needs anymore.

Think of it like a thermostat calling for heat while the furnace sits there doing nothing. The signal is loud, and in fact it gets louder because the loop never gets the feedback it is waiting for, so LH climbs while testosterone stays flat.

In this case, this is called primary hypogonadism and what that means is it doesn't matter how much more of these natural optimizations we throw at it, your testicles just aren't going to respond, your test isn't going to see a meaningful increase. Sleep, lifting, cutting body fat, zinc, all of it is still worth doing for other reasons, but none of it adds signal to a system that is already shouting.

But in a situation where say we look at your labs and your LH and your FSH are low, now most of the time this is a pituitary related issue or a hypothalamus related issue. Low testosterone with low LH is the furnace sitting idle because nobody turned the thermostat up.

So this problem is occurring in the brain in this case we can look to optimize using drugs like clomophene, clomid, we can add kisspeptin which is a peptide to basically tell your brain to start sending more signal, in which case your testicles will convert more testosterone. Clomiphene works by blocking estrogen receptors in the hypothalamus so your brain reads estrogen as lower than it is and pushes more GnRH out. Kisspeptin sits one step upstream of that and stimulates the GnRH neurons directly.

Nine times out of ten this is lifestyle related, but if we add these serums or even the peptides to fix the problem, this isn't a long-term therapy, meaning you can come off of it and if you've optimized your lifestyle we've got our pituitary where it's functioning again, most of the time you're going to see a meaningful long-term increase in your testosterone as long as you maintain those lifestyle interventions that you applied in order to get the result.
