Injectable eaa

You know.... I've been trying to take leucine in with every protein meal as a number of respected people seem to suggest. I really do think it's helped with the protein absorption....

I think my multi has leucine so I might be doing this too inadvertently.

"Ingesting 23 g of protein with 5 g of added leucine achieved near-maximal FSR after endurance exercise, an effect unlikely attributable to mTORC1-S6K-rpS6 signaling, insulin, or amino acids. Translating the effects of protein-leucine quantity onprotein synthesis to optimizing adaptation and performance requires further research."

"Leucine co-ingestion with a bolus of pure dietary protein further stimulates post-prandial muscle protein synthesis rates in elderly men."
Leucine co-ingestion improves post-prandial muscle protein accretion in elderly men. - PubMed - NCBI

"We conclude that coingestion of protein and leucine stimulates muscle protein synthesis and optimizes whole body protein balance compared with the intake of carbohydrate only."
Combined ingestion of protein and free leucine with carbohydrate increases postexercise muscle protein synthesis in vivo in male subjects. - PubMed - NCBI


So, there's beyond enough evidence to support it's addition to protein intake....

The evidence posted here is on pretty weak footing 'Pus.

Study 1 compared 75g protein and 15g Leucine to 23g protein and 5g leucine and no protein/no leucine. It's to be expected that MPS will be higher when you basically triple one's protein intake.

Study 2 was done on very elderly patients who's needs differ from ours and again, compared leucine and protein to just leucine with no protein. Of course an extra 20g of protein is going to make a difference

Study 3 did protein infusion which significantly alters things when compared to getting protein in the diet.

I know myself as well as many others like Zilla, Rockwell, Dr. Scally and Jim, CBS, etc also have mentioned that taking results from studies in an acute setting and applying them to chronic,long term results can be tricky. The body has a way of compensating for these small differences in the big picture so while these studies are interesting of course, there's still a lot left to be desired.

This boils down to "does it hurt, or potentially help?" for me... Can leucine supplementation "hurt"? Probably not. Can it POTENTIALLY boost protein absorption -> synthesis? Maybe... Worth it? Totally.

Very little risk of it hurting you. You’d probably have to be taking gallons of the shit and be on dialysis for it to really hurt you.

Good luck, it tastes like camel's cunt... I have to plug my nose if I mix leucine and NaC in the same shake.
