I am 32 years old and because of mistakes I have made using gear, I now have to do lifelong HRT. I am not thrilled about this but at age 19 there are so many alternatives that can help produce more test naturally. Anabolic eating is where I would start as well as squats and deadlifts. Why not take advantage of those great compound movements that are proven to raise level.
For me, the quality of life is what i am after I have had many test that result in levels at or below 200. Depression, fatigue loss in libido are all things that i have experienced. I had low levels in my early 20's and insisted on HRT, only compounding the situation because my doctor(who is in jail now, haha, not because of me) didn't administer properly. While I am getting honest, I am sure i did things to enhance what little supplementation he had to offfer.
I just wish I took the time to really get educated before using certain compounds. Androgels definitely worked for me but only help a 200 range turn into just below 600. I was grateful for the help but still wasn't optimum range for me. I would love to be in the low 700, but I think its gonna be a miracle to happen naturally.
