From what I've encountered, gels and patches work well with the physiology of some persons, and poorly with others, as with everything else biochemical in life.
I've been on gel for the past year and a half. My body couldn't stand even the very lowest dose of T via injection (50), and I went into severe hypertension with my first shot. I was switched to AndroGel two weeks later, and my blood pressure evened out, settling higher than it was pre-T, but not nearly so dangerous as it had been. My T blood levels are about 600, just right, even though I use only gel.
The results may be a bit slower, I'm not sure. I'm not a very good judge of progress. After less than a year, I passed completely and no one ever mistook me for a female again. My voice is very low. I have thick muscle development, hair and an annoying beard, and my face has changed shape. These seem to me to be congruent with the average span of adolescence in biological males in comparison with my chart of time on testosterone thus far.
You should talk to your doctor extensively and consider all of your options thoroughly before coming to any conclusions. I speak highly of AndroGel because the thrill of constant T levels does wonders for me, and keeps my mind exactly where I want it. I recommend it for that reason to any tguy who is anxious about shots, or who needs a good mental balance.
