I’m not a Doctor, and you should consult with yours if you feel you have any signs of hypogonadism. It’s a serious thing that you’ll need to treat one way or another. Luckily, I don’t suffer from this and have used supplements, diet, and lifestyle hacks to get my testosterone levels where I want them.
My take on the use of testosterone gel is that the side effects aren’t crazy like they are with therapeutic injections. However, if you do suffer from any side effects, let them be known to whomever administered your gel use. You could have an allergic reaction, especially if you already did with testosterone therapy.
The fact that a variety of health issues basically make this option void for many potential users makes this a less popular therapy, and again, this is supposed to be used to treat hypogonadism. I keep seeing people post pictures on social media of them using this, presumably without any condition, and I do believe that’s highly irresponsible.
For my money, there is nothing better than a natural supplement, a mindset that focuses on strength, rest, and diet, and well, a positive attitude.
