NOT all T boosters will work for everyone, and what would work for you best is probably a question of trial & error. Having said that, always try to buy a T booster which has several time-tested & scientifically backed ingredients that work via multiple mechanisms.

Here we try to compare the various ingredients in 3 popular Testosterone Boosters – Nugenix Total-T, TestoPrime and Prime Male. Every ingredient has a field “Ingredient Rating” on a scale of 1 to 5, on how likely is the ingredient going to help with boosting T levels (based on clinical evidence & user experiences). If you can’t see the “Ingredient Rating” on your device, click on the green “+” sign.
