"In conclusion, it is clear that leucine increases protein synthesis by increasing the activity of mTOR & the phosphorylation of eIF4G.
Leucine has a far greater stimulatory effect on protein synthesis than any other amino acid and it has been shown that protein synthesis increases similarly in response to a relatively small dose of leucine compared to a whole food meal.
It has also been demonstrated that adding leucine to a protein rich meal further increases the rate of skeletal muscle protein synthesis."

The one downfall in muscletechs
LEUKIC is that it lacks L-isoleucine and L-valine, its counterpart Branch Chain Amino Acids, which could lead to a defiency in the 2 BCAA's.
Personally, I use Scivation
Xtend which includes all 3 BCAA's and last 5 weeks if one took 6 scoops on workout days and 4 scoops on off days, a dosage of 15-20 grams of BCAA's is optimal,4-6 scoops.
(It also has 2.5 grams of glutamine and 1 gram of citrulline malate per 2 scoops) Hope this helps you out.
