I choose PA and have for the past 6+ months. My reasons for choosing PA over ARA are:Title sums it up -- you can choose only one which do you pick and why? Which is better in your opinion?
No accompanied joint pain, I have enough of that already (shoulder).
PA does not need to be cycled and does not lose its effectiveness.
It does not increase DOMS.
It is considered the healthier option.
PA is less expensive (Soy Lecithin granules )
