we do not rec amend taking it longer then 4 weeks unless you are using the new
derma sustain witch you can use as long as you like....I am 197lbs and I went as low as 3 pumps a day and you can see that in my thread it raised by test 100%
how ever I think its optimal dose is 4-5 pumps for a man my size or lager,and only for 4 weeks followed by derma sustain for as long as you like or just use derma sustain
btw bro I am glad you loved it just like every one else that has tried it.....just one more person to add to the list of many people that have tried and loved what it can do for them.
lol see i can have fun to.
