Lots of guys blast and cruise, most of them just don't talk about it.
For your HGH, you're going to want to run 3-4iu/day to see anything. Do a 5-on 2-off protocol (meaning 5 days on, then off 2 days). It will take a few months to really notice a whole lot, likely 3-6 months. Just doing 1iu/wk was, like you said, a waste. If your joints start to hurt, back the dose down to 2-3iu/day. If you want to maximize it or don't want to run it that long, start if towards the end of your blast and continue on past it. It will help you keep your gains from the blast, as well as get you pretty lean.
You're already shut down from from years of TRT, no need for PCT any longer. It may be of some benefit to "taper" down to normal dose at the end of the blast. Adjust AI dose based on sides, keep HCG the same.
