Through some research I've discovered some important things about when and how to take Leucine.<br /><br />Do not's:<br /><br />1) Do not take before your workout. Leucine stimulates the production of glycogen from glucose, and simultaneously prevents glycogen's breakdown into glucose, so you won't be getting enough energy to your muscles during your workout.<br /><br />2) Do not take leucine without food or in a fasted state. if you want to prevent catabolism, or muscle breakdown, take HMB. Leucine should be reserved for times you want to promote muscle synthesis, or anabolism.<br /><br />3) Do not take leucine consistently throughout the day. Leucine can cause insulin resistance when taken in large amounts and too consistently.<br /><br />4) Do not take in the morning. This is not an optimum time to build muscle anyway, as your body's natural cortisol spike is then. Wait until afternoon/evening.<br /><br />Do's:<br /><br />1) Take leucine with meals. Leucine signals muscle synthesis, so making sure you have the protein, carbohydrates and nutrients to go along with that is key. Taking leucine with a meal ensures you'll get a useful spike in insulin, and the body can get straight to building muscle.<br /><br />2) Take leucine intermittently in spikes. Choose a large meal toward the end of the day to take your leucine so you're body will have a lot to build muscle with and can build it while cortisol is low in the evening and while sleeping. On days you workout, taking it with a meal after you workout and a meal in the evening can still make sense. Avoid taking it during every meal during the day to prevent insulin resistance.<br /><br />So, a proper dosing schedule would be a tablespoon with dinner, and on days you have an especially heavy workout, a tablespoon with a meal after working out and another teaspoon with an evening meal before bed.

I have been using several Bulk Supplements for years, including L-Leucine. My gains with the Bulk Supplement products have been equal to or better than when I try the big name/big cost supplements. I go each year to the gigantic expo at the Mr. Olympia and have come home with literally hundreds of supplements to try. None work any better than the Bulk Supplement products. I am 64 and a current NPC bodybuilding competitor and a Senior Olympics powerlifting competitor, so I pay a lot of attention to my supplements.

The exercise physiologists used to talk a lot about BCAAs and how important they are for muscle growth, fat loss, and even life extension, but it's now known that only one of the BCAAs is truly important: leucine. This leucine from Bulk Supplements is practically tasteless, so it can be added to almost any food, and at 250 grams worth, will last you awhile at say a couple grams a dose. Great value and product, I never hesitate to order anything from Bulk Supplements.

I add this right to my protein powder shake along with the BCAA's from bulk supplements. Very good product from bulk supplements. I've been doing this combo for about a week and I have seen and felt results with of course proper diet and a decent workout plan. The only thing I would complain about and bulk supplements should seriously consider this......is their zip lock packaging. I've never received anything busted however the zip lock never wants to seal. It's basically not functional at all. I dump them in another container all together. Huge inconvenience especially when your using more than one product. Still 5 stars tho.
