Testosterone Supplements

Does anyone here take testosterone supplements? If so, what kind do you take, and what are some things you’ve noticed change over the duration of your use? I’m interested in hearing pros and cons about these.

Background: I’m 28 and have never taken testosterone supplements but recently overheard my brother in law talking to his step father about them, and I engaged in the conversation and after some research I found that these can possibly be beneficial to me.

Where I’m most interested is the blood flow. Sometimes I have a hard time maintaining erections in certain positions, likely due to lack of blood flow in that position, so this can potentially be beneficial there.

I’m pretty healthy, I’m 6’0, 190lbs with 15% bf, have good muscle mass. I do 3 days of strength training, 1 day of cardio, and 1 day hiit. On top of that I’d say I eat pretty healthy from food to snacks and I’ll have a “cheat” meal on the weekend
