I have taken Instone Forza T several times.
It has Trib, 6-oxo, and ZMA in it.
I did have a blood test while I was on it and it came back around 800 whatevers.
Which I guess is on the high side for 30 somethings. Unfortunately I have never had a blood test while I was off so I cant compare, but I do notice that I get a bit leaner and stronger while on. Nothing crazy, but I know it works for me.
