Especially at 57, it would be worth going in to have some lab work done to see what your natural test levels are. If your test levels are low, you'll have a hard time maintaining gains after the cycle, but if you were on HRT, you would be able to do very well, long term. I can't make a suggestion for an oral only cycle that is going to be a great mass builder, but if you were to run a little test, even 250mg EW along with an AI, you could make some solid gains. If you don't need HRT, after you are done, be sure to do a solid PCT

I'd suggest you keep oral use to a minimum. They are a lot harsher on your body. Cholesterol gets thrown out of wack quickly as do liver values. For a few wks, not a big deal, but if you are using for long enough to build a decent physique, these things can become a problem
