The only reason I wouldn't suggest GH for someone at 50, is if they have a histroy of cancer. Other than that, it will be a GREAT idea. For HRT purposes, I would suggest running about 2iu ED, IM, using an insulin needle. You will mix it with bacteriostatic water, which can be purchased all over the net, without a ton of digging. I would continue to run GH for as long as you can. Along with test, you will be running a powerhouse HRT program. I would expect a better quality of life. If cost is an issue, you can run it 5 days on, 2 off. As for brands, you will get the best effect from hyge's.
