L-Leucine, Worth it?

Hey everyone, i just wanted to open up a thread discussing L-Leucine.

Alot of hype around it recently i have noticed especially pre-peri workout.

I am wondering, have people been using L-Leucine? Is it worth the cost?

Thinking of a periworkout approach like:
60g Glucose, 10g Creatine, ~50g whey all mixed in a shake, half about 20 mins prior to training half about midpoint in the workout.

Just wondering if 10g L-Leucine would aide this protocol?

Thanks for your opinions and insights!

Just my opinion, from casual reading… you already get a good dose of Leucine in your whey protein. Would additional Leucine make your plan even more awesomer? I don’t know. I doubt it though.

BTW I had the same idea as you… I started adding Leucine to my peri-workout shakes. Does it speed up my recovery? I have no idea. But after this tub runs out, I will not re-stock up on Leucine.

I am under the impression that a good use of Leucine would be to supplement a less-than-great meal (bean burritos for example). In other words, the better your protein sources for any given meal, the less you might benefit from supplementing that meal with Leucine. Because it doesn’t mix well and tastes like ass, I only add Leucine to protein shakes (I never gag it down solo) and I eat plenty of top quality protein from a wide variety of sources (no tofu stir fry, or bean burritos) so it really doesn’t seem like I need it - I’m getting lots of Leucine and BCAA in my whey. Just my amateur opinion and YMMV.

Taking straight Leucine is always better than waiting for it to be ‘liberated’ from a protein source (I got this tidbit of info from the guy who was actually involved in the study that everyone else quotes -lol). The rationale for taking Leucine, or BCAAs in general, is for that instant access that you do not have when you are waiting for digestion, even from a ‘fast’ protein source such as whey.

What about adding it to a whey protein drink - seems unnecessary to me - the presence of whey might blunt the effects of an isolated amino. For that matter, so would any other type of protein feeding, no? Or can this ‘free’ amino access happen simultaneously along with food sources present?

leucine is included in the annconda protocol. along with beta aline, i think its one of the key ingredients in annconda.

someone write that there was an extra 6 grams in the protocol, but may be more.

I have been feeling that i don’t see it as all that useful to add to my protocol because i think anaconda uses it mostly for insulin effects it has and for the perfect amino combos.

Also i know CT uses it for pulsing 20-30 mins before a meal containing protein in order to maximize protein synthesis with his amino spiking idea.

Feel free to add more guys! Thanks for the contributions and STU grats on the pro-card man!
