are you able to mix something like xtend with your Surge and take it during and post workout?
You should be fine, as long as whatever you want to mix in doesn’t have fiber. Fiber will slow down Surge’s digestion and spoil the flush-nutrients-into-muscles-quickly goal. Xtend looks fine to add to your Surge.
Surge has bcaa’s in it…
yes buyt itll add more to it
