I have been running it stand alone for 2 weeks now...bottom line is that this stuff rocks as a stand alone test booster.
My sleep is better, boys are fuller, confidence is higher, libido is up, erections are harder, etc. all signs of increased test. Best part is that I am leaning out quite a bit and my strength and stamina in the gym is up by about 50%. I am dosing 1 cap morning and 1 cap at night before bed; tried 2/2 but got very aggressive and easily agitated, but 1/1 is perfect for me. This stuff isn't overkill though as I still have some estrogen based on sex drive, no dry joints, etc.
This of course is my personal experience. I trust LG and don't have any bloodwork to prove my experience. However, I am 33 years old, and have enough history and experience to know my body and to know what certain "compounds" or supplements do or don't do to me mentally and physically.
I highly recommend formadrol extreme as a stand alone test booster!
