Im curious if anyone thinks supplementing Amino Acids is ok/beneficial. I was looking at the standard BCAAS ( http://www.bodybuilding.com/store/musclepharm/bcaa-3-1-2.html )but I also came across a few other that are made from grass fed beef liver/meat ( http://www.bodybuilding.com/store/musclemeds/carnivor-beef-aminos.html ) which has BCAAs plus essential and non essential aminos. Looking to take them pre and post workout particularly when training fasted.

I think they can definitely be beneficial, however I don't know if they are the most cost effective method of spiking protein synthesis and getting amino acids into the bloodstream. Amino acid supplements can get quite pricey. I personally buy whey protein and leucine powder in bulk from truenutrition.com I don't remember my last bill but my 3 month supply is probably equivalent in price to 1 month of BCAA's. Spike the whey with some leucine and you will get the insulinogenic and protein-synthesis spiking effects of BCAA's with the bonus of having a more complete and still fast digesting protein source. If price is no option, and you are looking to get the effects without the added calories of the protein, then my favorite is USP Labs modern BCAA because of it's very high leucine content (and great taste). Something else I just remembered. Beef Liver Tabs. They're horse pills and smell like dog food, but you get a good whack of amino's plus some B-vitamins, and they are dirt cheap. Universal Nutrition makes a good product.

I've never consumed BCAAs.
The only supplementary protein I've ever used is either whey isolate, or gelatin.

Pretty much any complete source of protein will contain BCAAs as well. The use for BCAAs is that they are highly insulogenic for a small amount of protein, so they signal muscles to avoid going catabolic when fasted.
If you already consume complete proteins, say from meat, or whey, you don't need additional BCAAs, and whey itself is already insulogenic enough. Use BCAAs when you work out fasted, something like 10g-15g.
Even so, unless you plan to do IFs every day, or IFs that are much longer than the standard 16h, you're not going to catabolize muscle anyway.
Here's another hint, you don't need insulin to drive protein (or carbs) into your muscles - muscle, liver, and fat tissues have various glucose transporters called GLUTs, one of which GLUT4s responds to insulin. You can still get plenty of nutrients such as glucose for energy, or amino acids for tissue repair into your muscles without insulin. It's just that if insulin is triggered, GLUT4s will work to bring in more.
tl;dr So save your money, use BCAAs only when training fasted as part of an effort to lean out and gain muscle, eat more steak, and if you must, have some whey, but try to keep with the grassfed stuff. :)
