Gh will help but its no life changer. No supp is going to change your life, in itself. Sounds like you need to get your diet in order brother, and from there, GH will help take you that much further. Its not toatlly life changing but it does help with your goals. It might not hurt to get your test and thyroid levels checked too. At 35, things are going to be different than when you were 25. But honestly, if you were dieting down in 4 wks, safety aside, I'm sure you could have done better, if gave yourself more time to diet. You would have been abe to keep the food higher and carve more fat off while maintaining roundness or even growing. It sounds like you understand that, but I just wanted it throw it out there.
For GH dosing, around 2iu would be a good place to start. If you want to run gear with it, before looking at anavar, I would consider a low dose of test. 250mg EW, split into 2 doses would ne a low dose cycle with low water retention and low sides. Add in some arimidex and you have a soid dry cycle. With the right diet, you can tighten up and probably grow some too. I would run a plan like this for 12 wks. Then take 12 wks off and PCT. If you wanted to try anavar, it can be added on top of the test, around 40-60mg ED for the last 6-8 wks of the cycle.
