i'm planning to take some new supplements when I start lifting again. I planned on taking Ultra 4 and Density. Then I started reading up on Ultra 40. Since U40 has all the essential amino acids, would I even want to take Density? Does anybody know how those two compare? Also, could U40 alone replace U4? I know it has more B12, but how does it stack up for everything else? Would you take all three, just Ultra 40, or just Density/Ultra 4?

Well to keep it simple:

Density is best taken pre/post workout
when your muscles are in most need of aminos.

Ultra 40 would be taken with your meals,
many take Mass Aminos as they compliment
each other along with Ultra 4 (multi vitamin).

The idea is to spread out your intake of
amninos for muscle growth - that they
have aminos available to them around the clock.

I have been taking Bev products for 10 years.
I always take U40 and Mass aminos with meals.
At 8 weeks pre-contest diet I added Density at 2 per meal so, 12 a day. The results were awesome!!! If you can afford U40, Mass Aminos and Density definately do it!
I'm now on a lean gain and won't give up any of them!!
