some guys have run it up to 3 months, then taken a month off, and are starting the product again..
I tend to do 2 bottles, then off for 1 month.. seems to still be effective..
I also ran it 6 caps the 1st time using it as my only pct, worked well, but not completely.. definitely helped allot in the libido area, and in increasing my testicle size
strength remained the same, and i lost no weight..
good luck
