For the longest time I always felt weird about trying a HGH supplement. Then after overhearing a conversation at my gym where some guys were talking about HGH-X2, I started doing some more research. Once I understood that HGH supplements were meant to support and improve your body's natural HGH production, I felt less weird about it. So I went ahead and gave HGH-X2 a try. It's given me that extra edge that I always felt I needed. Plus, I've noticed my recovery time has seriously improved. All I can say is that if you're even a little curious about HGH, the only way to see if it's right for you, is to try it. I did! And I don't regret it.
Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes. 
How it works: In the stomach B-vitamins will release and control gastric juice, help absorb and digest macronutrients, which in turn get more out of the things you eat. Next to that all of them have a host of individual properties. B6 is a good liver-protector, B9 is good for absorbing things in cells, B12 is needed for energy and so on and so on. If we could get all our nutrients from food easily and eat enough, this would no doubt be my Nr2 supplement. If you are a person who can eat big and watch his grocery bill and you have decent genetics, a B-complex and multi-vitamin is all you really need to grow.
