Men often opt to treat their low testosterone in order to raise their energy levels or increase their libido. What they don't always realize is that treating their low testosterone tends to have other benefits, too. Here are some other surprising — and positive — changes you may start to notice after beginning testosterone replacement therapy.

Better Endurance

If you're someone who exercises regularly, you may notice that your endurance improves significantly after beginning low testosterone treatments. For example, if you used to feel tired after jogging two miles, you may suddenly feel like you can jog four comfortably. This is because testosterone supplements tend to boost your red blood cell production. With more red blood cells, your body is better able to carry oxygen and nutrients to its tissues, which improves your endurance. This can be a really positive change if you're someone who cycles, runs, or participates in other endurance activities.

Fewer Blood Sugar Crashes

Do you notice that after you eat sugar, you initially feel energized, but then you crash? This may change after you start taking testosterone supplements. You may find, for example, that you are able to eat more carbohydrates without feeling a lack of energy hours afterwards. This is because testosterone can improve your insulin sensitivity and lead to more stable blood sugar levels. If you're a pre-diabetic, beginning testosterone supplements may actually help you avoid developing diabetes — but check with your doctor before you take testosterone for this reason, alone.

More Relaxed Mood

Sometimes, men don't notice that their moods are a bit irritable and unstable, but those around you may notice this. They may even tell you about it, but you may feel like there's nothing you can do to change it. But once you take testosterone supplements, you'll likely find that this changes. You may find yourself slower to anger, and you may realize that you feel a sense of calm and relaxation a lot of the time. Testosterone can be a great mood regulator when you use it to correct low T. For some men, it works better than anxiety medications and anger management strategies.

If you start taking testosterone supplements, be prepared for your body and your mind to change. Often, the changes that occur are different from the ones you may expect. If you experience any of the changes above, you now know that you're not alone. Look into low t treatments near you.
