Clinical Studies


Can higher levels of IGF-1 mean higher levels of HGH? By now you’ve probably done your research and discovered the amazing benefits of HGH.

But there’s another exciting “abbreviation” that you should know about, and that’s IGF-1. IGF-1 stands for Insulin-Like Growth Factor, but that’s not the important part.

The important part is researchers discovered when HGH is naturally secreted in the pituitary gland that the production of IGF-1 is initiated. They also discovered that injecting HGH increases the production of IGF-1.

Are you starting to see the link?

That means, according to medical research, higher levels of IGF-1 could indicate higher levels of HGH. Read on to learn about an interesting study.

12-Week Study Shows 28.57% Increase of IGF-1 Levels

In a 12-week, double-blind, placebo-controlled clinical trial, 61 participants were split into two groups.

The first group received the GenF20® Plus system, the spray and tablets, for increasing HGH production and the second group got a placebo.

The group taking GenF20® Plus was given the suggested serving amount.

At the end of the 12 weeks, the researchers measured the IGF-1 levels of each participant.

The placebo group didn’t see any increase.

But the researchers were astonished when they discovered that the participants who received GenF20® Plus showed a 28.57% increase of IGF-1.

Note: This study did not measure HGH levels directly. This clinical trial measured IGF-1. It’s scientifically shown that IGF-1 levels increase when there’s more HGH production.
