I've been taking 5mg BCAA fasted pre-workout in the morning (along with some coffee or tea) and feel like it definitely helps my workouts. Right now I'm pretty much VLC Primal (eating cheese and other high-fat low sugar dairy) and have also noticed that BCAA seems to knock down the overall hunger/carb-cravings (likely due to gluconeogenesis).

I save the whey and/or casein (from dairy) for post workout as it has been shown to promote a positive nitrogen balance in numerous studies.

Bodybuilding.com has a pure BCAA powder by SciFit (what I bought) and it is a huge 2lb jug that was pretty cheap. They typically have prices about 50% off what you would find at GNC or any other brick-and-mortar store.

I just popped some BCAAs right before I clicked on Paleohacks. I take NSI from Vitacost just for cost reasons and they dont have additives. Now off to deadlifts, squatzzz, power cleeeans!!

I use BCAAs(Xtend), although I'm not planning on getting another container when I run out. I definitely notice an increase in energy, and my lifts, when I'm supplementing with BCAAs, both when I train fasted and not. I'm also doing keto right now, and I feel that BCAAs are very helpful on keto, but with carbs, I feel that the BCAAs don't help as much.

I'm planning on just taking a 21g of protein whey shake pre-workout, just to supply AAs during the workout. I've done it before with similar results to BCAAs.

i have been using Scivation Extend and No doze plus, fasted pre workout for a year now aka leangains and have noticed that i have more focus and energy.

i would recommend it for any metcon's as training fasted would give you some serious prowler flu.

currently im using purple wrath and 150 mg caffeine and have noticed that after 30 min my whole body startes tingling and my skin feels like its a bout to break out in a rash. i have been taking normal doses but i guess everyone is different.

all in all i rate Scivation as being my pic for BCAA's

I thought the purple wrath tasted disgusting. Xtend tastes much better but has AceK and Splenda in it. I take capsules now.

I see a lot of people using Xtend pre workout. I have always used it as recommended, intra workout. I have used Jack3d pre workout and it didnt help me much but did make my stomach hurt. I stopped using Xtend when I went Paleo due to the sweeteners but I may add it back in. I did notice a difference using it during a workout.

I take twin labs BCAA tablets as soon as I wake up with a glass of water, then with every meal.

I take one serving, four scoops, of scivation pre workout. This is NOT in a fasted state btw.

I've wondered about beta alanine though. I know some mixes have it, and some people dislike it cuz it makes your feel "tingly." I'd love to hear from users.

I like the scivation, feel like I get a little buzz of energy. Fake sugar sucks but it's such a small amount, it's worth it.

The best way to utilize BCAAs is pre-workout to preserve muscle mass, especially on a calorie restricted or low-carb diet. For example you could try, green tea and BCAAs on and empty stomach before a morning run, walk, or some resistance training?
