It is true enough that people react differently to hormones ..... as well as any medications. My brother-in-law is working with a 10 year old patient right now that merely went in to have a mole removed from his back. He had a really bad reaction to the anaesthesia and now his fingers, toes, and other body parts are rotting off.
So yes, any advice has to be given a disclaimer......even if you are going to take an aspirin or tylenol, or .....etc. The only advice that we can give is general consensus. I personally experiment on myself and poke myself monthly to do bloodwork to test what effect different combinations and doses of hormones do.
My comments are from results on myself and my close circle of friends that also serve somewhat as guinnea pigs.
With regard to HGH, I have monitored myself and friends, and my comment on dose is based on what I have found to be the case from my own experimentation and from that of my friends....all of whom have been poked, x-rayed and otherwise monitored beyond what any person should have to endure
Bask8kase's point is well taken though.....be careful out there. Get monitored from time to time. Watch out for any weird effects.
