Well I do beleive the difference would be two things. The Alpha Male also has the benefit of having M as well as the TRIBEX and RED KAT combined so you have an anti E effect.
As for the dose effectiveness. I think that boils down to the superior delivery system. The Alpha Male is nano. dispersed. More bioavailable.
Sometimes MORE is not always better.
I will say I have tried TRIBEX and Alpha Male. While both are Great. Alpha Male is TOP DOG IMO.
Probably save you soe Jack as well then buying both. Leaving more $ for food and/or Grow!/Surge to feed the need.
Ya Know. That boosted T wont be worth a Darn without nutrients to back it up.
Hope that helps,
