I def agree with Slimmer Me and bass, besides u can always ask the dr. about a trial run and how that can be managed safely to get ur reg test to kick back in if u don't like it. I can't for the life of me see how u won't though. I bought my dad a few books about trt and hrt and the health benefits, etc before we had a major falling out a few months ago. He told me he bought some otc stuff to appease me, my hope is he would go for a trt route for a happier, healthier life in his golden yrs.
From my extremely limited knowledge of trt I would def go the test cyp route rather than a test patch or creme if ur dr is gonna give u that, but ur a grown man and obviously seem more than capable of making ur own decisions. Just offering input from my limited perspective.
