I think I may have tackled this one last week, but it could just be a similar question. You could add in 200mg deca to your HRT program for 12 wks, as it is. Or you could raise your test a little, if you would like to get a stronger effect. Something along the lines of 400mg Test, 300mg Deca would still be a very moderate dose and would give you a decent pop. As for the growth, it's a longer term commitment and depends on your goals with it. If you want to add it in as part of your HRT program, you could use 2-3iu a day. I would use it for at least 4-5 months. A year if you can afford to. Stay on for the rest of your life, if you can afford to and cycle off for maybe 1 month, every 12 months, just to take a break. With this dose, older guys seem to see more of a difference than younger guys that are already naturally producing a good amount of GH. You could increase the dose to 3-4iu to get a better impact. I would expect over the long haul, to see a better overall transformation. Better fat loss and improved muscle growth. The effect will never be as strong as that of a steroid cycle, but especially for older guys, it can improve quality overall.
