p90x multi's and shakes?

I didn't buy and supplements or shakes etc other than protein from my local store.

First, congrats with your new purchase of the P90X program. I absolutely love it!

I did 2 days with no suppliments, could barely lift my arms for the next couple of days.

I then started having whey protein shakes/smoothies. I also got some creatine for post workout recovery. I've sampled around and now here's what I do...

Shakeology - meal/protein shake late morning snack.
Whey Protein smoothie - late afternoon snack
Pre workout - C4 Extreme or Jacked3d
Post workout - MuscleTech Cell Tech creatine
Post workout - EAS Myoplex 42g protein RTD (ready to drink) shake
Rainbow light mens mutli vitamin

I'm a little over halfway thru my first round of P90X. Week 5 I did an experiment, I stopped taking my suppliments, besides the protein (Shakeology, Whey Protein smoothies and EAS Myoplex) as these are used as meals and protein sources more than anything else. I found I wasn't bringing it as hard as when I took my pre workout suppliment, nor did my body recover as quickly (a lot more sore the next day(s) when I dont take my post workout suppliment).

That has been my experience, to each their own...as to answering your question "Are these necessary" - That will depend on your body and its' needs and what your goals are with the program.

Cheers!

Chin up bar, push up handles, good mix of weights that you can quickly interchange, resistant bands, yoga mat, and a yoga block. Food wise, just try to eat from the Tier 1 & 2 and lightly Tier 3. Good luck

Oh...and I just used whey protein w/ chocolate milk.
