What will HGH do for me?
Nothing. A lot. It really depends on "you", your expectations, your training, diet, other supplementation use, etc..
By itself, HGH will induce more fat burning and muscle recovery than normal. However, even though HGH is cheaper now than it was years ago, it is still a rather expensive option for those just wanting to burn some fat. (adjust the diet, hit the cardio you fat slags).
Combining it with AAS is where it's real magic lies because of it's synergistic nature. Think of AAS as regular grade gasoline and HGH turning them into higher premium grade fuel. You can get better results from AAS while using a bit less norm just by incorporating HGH.
It will still increase fat burning, but the main advantage is in it's recovery support. You recovery faster, heal better and often old nagging injuries are reduced to a degree. Which basically comes down to a simple mathematical formula on why it is a great weapon in the chemical enhancement arsenal.
The faster you recovery = the faster you can work the muscle again = the more workout per year that muscle gets = the more growth that occurs.
If you work each muscle group once a week, that is 52 workouts per year. Which is 52 times you have the opportunity to induce growth. (Doesn't sound like much huh?)
Increasing your recovery ability to where you work each muscle group (or prioritize weak ones) twice every ten days will give you more workouts per year in the long run and more chances to induce growth.
HGH can also work along AAS and increase protein synthesis which helps you get the most from your diet. If you are going to suffer through bland food and low carbs, it at least makes sense to have something to work for your benefit right?
