Good information. My PCP would not prescribe injectable T because he felt it was too easily abused. I switched to a different provider and have been injecting for the last 8 weeks. Here's why I like injectable over gel. I should add that I do not have any experience with compounded cream.
I travel for a living and currently inject every 5 days, which means I rarely have to worry about it while on the road as I always inject at home. Also, I was applying two tubes of Testim on a daily basis, which was at least a 10 minute process including wringing out the tubes, using latex gloves, waiting for my skin to dry etc. While 10 minutes may not seem like much time, it adds up to 60 hours over the course of a year. Simply unacceptable. It takes me less than 3 minutes to inject 5 days worth of testosterone. Also, consistently applying my Testim while traveling all over the country was very difficult and it needs to be done daily.
Injectable is SIGNIFICANTLY cheaper than any gel on the market (testim, androgel). Unfortunately, there are no big drug companies pushing injectable treatment so it goes under the radar.
Those are the two big ones, but what else is there besides time and money. Why spend 60 hours doing anything when you can do it in less than 4?
Having experienced both, I prefer injectable T. Oddly enough, I was originally clued into injectable T by my pharmacist. I was actually quite irritated when she told me what the cost was and that I only had to inject once a week when my PCP had me going through this elaborate daily ritual, slathering stinky alchohol based Testim all over myself when all I had to do was inject 4 times a month.
