Too Much or Too Little Testosterone? How to Tell While You’re on TRT

So you’re on testosterone. Great. But here’s the question nobody really answers for you — how do you actually know if your dose is right? Because your lab number is one thing. How you feel is another thing entirely. And I’ve had guys walk in with a “perfect” level who feel terrible, and guys at the low end who feel fantastic. So let’s talk about how you actually read your own body.

Let’s start with too little. If you’re underdosed, honestly, you feel like you did before you started. The fatigue creeps back. Brain fog. Motivation’s gone. Libido drops off. You’re not recovering from workouts. And here’s the classic pattern — and this is a big one — you feel decent for the first few days after your shot and then by day six or seven you crash. That’s not a dose problem necessarily. That’s a frequency problem. Your level is peaking and then falling off a cliff. Which is why I’m a fan of smaller, more frequent injections instead of one big dose every two weeks. Smoother levels, fewer roller coasters.

 

Watch: Too Much or Too Little Testosterone | Know the Signs!

Now too much. What does that look like? Irritability — and it’s often your wife who notices before you do. Trouble sleeping. Acne, oily skin. Water retention, puffiness in the face. Sometimes anxiety, sometimes a racing heart. Some guys get aggressive, short-fused. And weirdly, too much testosterone can lower libido too, because it converts into more estrogen. So high and low can look similar. That’s why you don’t guess. You test.

Which brings me to the two things I watch most closely. Hematocrit and estradiol.

Hematocrit — that’s the percentage of your blood that’s red blood cells. Testosterone tells your bone marrow to make more of them. That’s normal. But if it climbs too high, your blood gets thick. Like syrup instead of water. And thick blood is harder to push, it strains your heart, and it raises clotting risk. Symptoms? Headaches. Flushed red face. Dizziness. Ringing in the ears. High blood pressure showing up out of nowhere.

So how do you manage it without extra medication? First — hydrate. Seriously. Dehydration alone concentrates your blood and fakes a high hematocrit. Second — smaller, more frequent doses. Those big peaks are what drive red cell production. Third — check for sleep apnea. This one gets missed constantly. If you’re snoring, if you’re waking up tired, low oxygen at night raises hematocrit on its own, and testosterone makes it worse. Fourth — donate blood. That’s it. Regular donation, and you’ve solved it. And go easy on nicotine, and get your dose right in the first place.

Now estradiol. Everybody’s terrified of estrogen. Don’t be. You need estrogen. It’s what protects your bones, your brain, your heart, and it’s a big part of your libido. Crushing it with anastrozole is one of the most common mistakes I see, and guys end up with joint pain, no sex drive, depression, and long term, bad bones.

So how do you manage estradiol without a drug? Body fat. That’s the answer most guys don’t want to hear. Fat tissue is where aromatase lives — that’s the enzyme that turns testosterone into estrogen. More belly fat, more conversion. Lose the fat, the problem often fixes itself. Then again — dose and frequency. Big peaks drive big conversion. Support your liver, because your liver clears estrogen. Cruciferous vegetables help. Alcohol hurts, a lot. And keep your gut healthy, because that’s where estrogen gets eliminated.

Do the boring stuff first. Most of the time you don’t need the extra pill.
