To me the question is what do you want/expect from HGH?
Second, can you achieve that/those from a less expensive, easier to purchase, less sides product?
Third, do you have the patience and dedication to lift, diet etc. that is required for a long term product. That is why people say it is a failure, but the fact is they fail the product.
Another questions is, are you 35 or older and have higher than average income and want to look great and feel great and use as little as posible anabolic steroids?
To answer you questions more specificly:
1. I have read alot about human growth hormone,and it seems that it is unbelievable, i mean you can actually add muscle cells? Yes, you can add more muscle cells but be preparred to take it for 6 months. For muscle you would be looking at 4-6IU's per day. (No that is not excessive when looking for muscle gains) If muscle gain is your main concern than you would want to take between 8-12IU's 3 x week PWO
2. f human growth hormone - somatropin - is all that, why isnt every one using it then ? .
It is very expensive to take a minimum of 6 months correctly, not everyone takes it correctly they use 2IU's per day for 2-4 months, and they don't get the results they expected. People want the quick and easy there is no quick and easy with GH.
My question to you why would so many pro athletes use it if it was worthless?
Primordial: Why do you believe IM is better than SubQ?
