Do some reaserch on the affects of that stuff. Before I started my injections, I looked at all the different methods and I found that the injections were the safest. I started out at 1 ml every 4 weeks and then I would crash after the 3rd week. Then I moved to 1 ml every 3 weeks and I would start to crash a number of days before the 3 weeks were up for my next shot. Then I moved to 2 weeks and after a few times, I felt like I ODed on it. I was up in the middle of the night feeling like I had drank 40 cases of Coke and 40 shots of espresso. It sucked. I finally found that every 16 days is the right number for me and it has been working great. I don't have any highs or lows. You just have to find out what that number is for you. Took me about a year to get to that point but now that I'm here I'm glad I did it.
So yeah, just take a look at the other methods and which method is safest for T replacement therapy. I found numerous pages that said the injections were the safest.
Good luck!
