Just a few thoughts:
Acromegaly is a disease. Either you have it, or you don't. Use of exogenous GH will not cause acromegaly...this is a myth, like the steroid horror stories we have all heard and disregarded. Individuals with acromegaly lack the feedback mechanisms that protect the normal body from producing too much GH.
Some individuals are GH deficient, on the other hand. Either their defense mechanism works too well, or the pituitary is diseased or aged. This is especially true in older people. By age 60, we produce 60% less than when we were younger.
Will higher doses yield better results? That depends on many factors. I am an old fart, so I get great results on relatively light doses. A younger lifter may need more. But, consider this......our normal GH production ranges from .5 to 1.5iu a day. Supplementing 4 or 6 or 8 iu is a huge bump. Can we use it all? Depends on how strong your body's feedback defense mechanisms are.
How to maximize results? I believe that insulin supplementation is essential with exogenous GH use. The body's main defense mechanism to what it senses to be too much GH is to down-regulate insulin sensitivity, and the production of IGF factors. Use an oral steroid in your stack. On the first pass through the liver, orals cause large releases of IGF-1,2,3 etc. And, of course, plenty of test.
Timing is important. Don't inject at bedtime despite what you have been told. During the first REM sleepcycle, we produce the bulk of our natural GH. This will be suppressed if an excess of GH is sensed in the system. Instead, inject during a "flat" period.... mid morning, late afternoon......and take advantage of your night time spike.
I was interested to hear that you had good results with the chinabase product, ripped. The reviews are mixed. I know 2 bros who had injection infections from chinese GH that arrived warm. I take it your cold-pack survived the trip. I prefer Sero or Huma, cause the handling is not near as tricky. To be fair, the chinaman will reship if there is a problem, but meanwhile, you are mid-cycle waiting on GH.
Moose, I use a 12 week cycle of GH 3 times a year. Month one - 4.5iu, month 2 - 6iu, month 3 - 9iu. So you can tell how i feel about GH supplementation. No way I stay big and lean at 52 without it.
