Anyone heard of GH3 & GH7?

I've recently done a lot of reading on anti-aging and came upon the site www.realgerovital.com which sells the anti-aging product GH3. i don't recall the site for GH7 but it is a 'new & improved' version of GH3.
These are both made with the base ingredient 'procaine' which is a safe, organic version of what dentists use to numb gums.
The testimonials about these products are truly amazing and the pictures on the sites prove that they actually do reverse aging.

GH7 claims to work better than GH3 being ingredients have been added to enable the body to utilize the procaine more efficiently thereby releasing more into the system.
The makers of GH7 claim that the testimonials on the realgerovital site are from people using the injectable GH3, not the tablets, and that GH7 (an oral preparation) has the same effect as injectable GH3. (GH7 has an ingredient added to support the liver.)

Is this type of anti-aging safe? Can it damage the liver? Should someone with liver problems take this? What side effects might it have on the system; long-term and otherwise? If both of these are unsafe; is there something safe out there that produces similar results?

If anyone has any knowledge of these products or, better yet, has used them-- Would you mind sharing your knowledge with me?

thank you. Tweet
