everybody has their own preferences..
here, Dex and I disagree..while I will grant that,
in general to build muscle, it is most optimal to have a feeding or two in prior to training, it does not have to be mandatory. you just need to have support supplements in place to ensure that you are not using muscle stores for energy. the A-Stack is golden for that!
I'll share my personal fasted training upon rising protocol with you, with those supps you mention:
wake, take AP, 3 PF, 3 Prime
15min later, begin sipping BCAA mix
[*this should be a powder mix like PurpleWraath or Xtend, and total consumption should be based on this formula:
bodyweight x .2g = total BCAA consumption pre/intra/postworkout]
15min later, begin training -- after having consumed 1/3 of BCAA drink to this point
drink another 1/3 of mix by halfway point of workout
at completion of training, finish last 1/3 of drink, and take another AP cap
15min later, have postWO nutrition/breakfast
while I use this particular schematic primarily for fat-loss, this will work for you to build muscle as well; protecting muscle stores/aid in recovery/induce growth due to AP's inducing fatty oxidization for energy..this will protect precious muscle tissue in a fasted state, and the BCAA's will act in synergism for this aspect as well as providing nutrients to cellular tissue.
waiting the 15min to eat after training will allow further absorption of aminos due to increased bloodflow, without disrupting the process by eating and hence directing bloodflow to the gut for digestion.
follow with a largfe breakfast.
