If you are considering using an hgh supplement to fight the effects of aging, there are several types to choose from.  Hgh supplements can be given orally or by injection.  The fastest results come from the injections, but they can be quite expensive and need to be administered two to four times a day.  Saizen hgh is a brand name of Somatropin.  Somatropin can also be found in generic form.  It costs less than the brand name drug, but is FDA approved so there is no concern about the safety or quality of the drug.  Genf20 is another popular anti-aging hgh supplement which is taken orally.  Whatever form you choose, be certain it is prescribed by a qualified doctor who will determine the correct type and dosage for you.
