Good product but does not mix well alone.  Add it to your protein shakes post workout.  *

Leucine is the main ingredient in signaling Muscle Protein Synthesis. Add 2.5g-5g right before each meal to ensure that the amount of protein in my meal reaches the threshold to spike Muscle Protein Synthesis. AllMax has the best prices and deals on Leucine anywhere else.*

It would not mix in water it just clumped up. Hand to god I tried one scoop and was so disappointed and upset I took the jar and threw it in the trash.  If there was 0 stars option I would have used it.  Honestly it doesn’t even deserve 1/2 a star.  *

Doesn't taste very good, and Doesn't mix well, or dissolve easily in juice, but I've been adding it to my protein shakes, and that works best for me, only been using for a couple weeks, so a bit to early to see if it's making a difference*

Probably one of the most important BCAAs. Leucine jumpstarts muscle protein synthesis. Definitely take this intra workout so it’s absorbed n assimilated before you hit your post workout shake / meal. Will definitely purchase again. Do not take more than 5 mg at once or risk some diarrhea . Some recent studies suggest a low isoleucine diet can improve lifespan. That’s hard to do ;so taking extra leucine- competes with isoleucine , limiting iso in your body*

AllMa Leucine is really good for treating muscle fatigue post workout, I mix it with Allmax Glutamine and protien powder and drink right after my last set. It also helps retain muscle when its time to some swimming,surfing or biking.*

The literature seems to support the use of leucine for increasing muscle size. Perhaps it is being older than age 60, but using leucine regularly for a year has made only slight difference for me. Yet, I will probably continue.*
