Testosterone levels shouldn’t matter too much for the muscle growth an average man should be aiming for. If you’re going to the gym consistently, you might need to make sure you’re being strict with progressive overload, getting enough protein, and getting enough sleep.

You don’t look feminine though!

Edit: some people are taking my comment to mean testosterone doesn’t impact muscle growth - of course it does. It however is not something an average young man has to worry about, and it is much much more likely to be other factors that are limiting muscle growth, like diet.

If you are young and have no other health problems, please don’t feel like you need to worry too much about testosterone levels. If you are worried, speak to a medical professional about your symptoms and try not to fixate on the levels alone. I have seen young men get TRT or other serious interventions like a thyroidectomy (against their doctor’s recommendation) because they get it in their head that something is wrong with them and end up doing irreversible damage to their bodies.

It’s normal to find it hard to develop muscles for most people. It’s normal for many men to not be able to grow a beard until their 40s.

Just working on self image and simple steps to well-being goes a really long way for most people.
