Been on t replacement for about 5 years. never had headache. But some other intersting advice. Consider ordering from life extension pharmacy. they can compound any rx and the cost is 49 to 59 dollars per 3 months ( if your doc will write a 90 day supply at once ) i was paying 240 for androgel with my insurance co-pay so i just pay the 59 out of pocket. im saving 200 every 3 months. Also they can adjust it to any icrement rather than the 2.5 ml increments you are limited to with androgel.
And lastly they can compound your dose into a very small amount of creme or gel so it makes application quicker, neater and easier.
I also take arimidex to prevent the test from converting to estrogen. I take it every other day because it's very potent, has a long half life and its enough to keep my estrogens in the low range.
Hope this helps,
Larry
