Common questions

Which proteins & peptides form is best absorbed?

Whey Protein leads at 95% bioavailability. Absorption is the number that decides how much of the dose reaches you, so it matters more than the milligrams on the label.

What is the difference between proteins & peptides forms?

They deliver the same active compound but differ in absorption, tolerance and cost per month. The cheaper forms are usually the ones absorbed least.
