First of all, awesome rear double bi....I am in touch with the competitive circuit and if the rest of you looks as good, you should be on stage.
Back to your question, 10 plus IU's a day is definitely unhealthy, your organs and god knows what (cancer) else can happen. Having said that, if you are getting on stage, it is only about winning, not health. If you can afford 15 iu's of pharm, go for it. OK, back to the OT.
There have been a few good studies recently that can provide a good degree of info. One done on children found that going e2d preserved the bodies own ability to produce GH.
Other studies have looked at the potential of GH to cause cancer. The logic is simple, since GH makes things grow, it probably makes cancer cells grow, right?
Not really. First, the study showed that LOW GH is actually carcinogenic. The logic is that low GH means that the body is less able to produce antibodies to fight cancer cells.
Now, admitedly, this theory is something I extrapolated from several studies and logic. The safest amount of GH is a dosage that puts you in the high normal range. This range is based upon your IGF-1 levels. Yes, there is a lot of noise out there trumpeting HPCL testing, but IGF-1 is still the best measure going (especially if you also have blood serum and Mass specs). Real scientists doing real research still use IGF-1.
OK, so here is the theory: High normal levels make the immune system stronger, more able to fight off cancer, more able to heal injuries and in general have a more robust ability to heal and regenerate itself.
I am an old man, and I do every test possible to my GH, which is a Chinese generic. I do 3 iu's e2d, or 1.5 iu's a day. The IGF-1 range for my age is 60-190 ng.
I tested at an average of 70 ngs prior to GH. I have 3.5 years of data. My IGF-1 went up to 182ng.
Have I gained a lot of muscle? No, maybe 6-8 lbs in a year. But here is the crazy part: My worst body parts (chest bi's) have improved dramatically from GH.
Regular steroids make my strongest body parts (legs, tri's, back) improve more so than my weakest. I eat stupid amounts of food, porterhouse steak and a whole plate of Smores last night. My wife is in a perpetual state of shock, lol.
I plan on running low dose GH for the rest of my life.
So, to summarize: low GH, bad, high normal GH good.
Now OP, I need to know your plans: If you are after an IFBB pro card (and the pay is shit for every one but the top 10....you can make good money other ways) then yes, run 10 plus iu's. If you just have a particular amatuer show you want to win, go for it. No one can ever take away the fact that you are a champion, so IMO no price can be put on that.
If you are after long term health, want to be an athlete at age 65, then go low dose for the rest vof your life.
