Two initial 'concerns' I have about the time release's relevance. First, is 3gm of leucine over a 4hr+ window really going to make any non-trivial (ie significant) impact on mTOR/MPS? To me that quantity, over such a time span, seems insignificant (compared to a standard bolus dose). As a bolus that quantity makes sense, but 3gm time-released sounds like a miniscule trickle too small to have any long term impact. Secondly, and somewhat relatedly, how is it any different than diluting 3gm of leucine powder in water and sipping on that over the same length of time? Purely convenience?
ah, okay. Just to be absolutely clear...you are saying you will effectively get two 3gm leucine doses with the product, both bolus's? If so, I was mistakenly imagining the second 'dose' (the time released one) to be 3gm *gradually* over time, as opposed to all at once (relatively speaking).
It would be 2.5g immediate, 3g approximately 3 hours later.
If one eats every 3hrs, would the product be of little additional benefit?

Thanks, it would seem my initial reservations were perhaps unfounded. I can imagine scenarios where this time release may be of benefit, but what if you regularly eat every 3hrs or so, and these meals are already leucine rich? Any additional benefit?
In for more. Joined "the lab" earlier and I'm curious to see what the intro-deal will be![]()
this would be ideal for those who practice IF/LG as well 8)Could be for convenience factor if you don't have a high protein meal on you. Just my guess though
Contrary to our hypothesis, the W6+BCAAs treatment resulted
in MPS rates that were less robust than with W6+High-Leu and
W25 treatments. These differences occurred despite the fact that
supplemental isoleucine and valine attenuated the decline in
concentrations of these amino acids in the blood compared with
that observed after the W6+High-Leu treatment (Table 3); how-
ever, intracellular concentrations of isoleucine and valine were
not different between these treatments (Table 4). In addition, the
W6+BCAAs treatment was associated with a lower intracellular
leucine concentration at 1.5 h, a lower mean leucine AUC pos ,
a lower leucine C max , and a greater T max than with the W6+High-
Leu treatment (Table 3). We have shown that a rapid amino-
acidemia after protein feeding stimulates greater MPS rates after
resistance exercise than a slow protracted aminoacidemia (46).
Therefore, we speculate that the greater T max for leucine, iso-
leucine, valine and SEAAs after W6+BCAAs compared with
W6+High-Leu may partially explain the observed differences in
MPS rates. Because BCAAs share a common intestinal trans-
porter, differences in amino acid appearance profiles between
W6+BCAAs and W6+High-Leu treatments likely represents
antagonism between BCAAs for uptake from the gut, which is
congruent with data showing that isoleucine and valine compete
with and can impede leucine absorption (47). The same effect
could be true for the transsarcolemmal BCAA transport because
BCAAs share the same transporter at that site (48).
Myokem, to avoid confusion, the proper term for what you guys are achieving is "delayed release," not "time released"
I just joined the lab.

I would dump the Iso-Leucine and Valine, personally:

I thought this was just a marketing thing? Omega Sports Shred XT calls one of it's caffeine based ingredients time released, was the proper name for that actually delayed release? Guess it really doesn't matter one way or the other just curious Coop.
They mean two different things... "time released" would mean released consistently over time, whereas "delayed release" would mean some now, and some later in a bolus dose each time (this is the case here)

Maybe Coop can go argue with Compound Solutions on the accuracy of the name, but I have no control over the terminology given by them.
Well myself and many others thought time release meant a slow release (which it does). But a delayed release means an instant release several hours later, which this is.
Edit: Ah I see, whey out performed added leucine with BCAA vs added leucine with Whey.
Interdasting. I haven't read much literature on BCAAs and Leucine etc as I find it to be slightly tedious. I may need to read more
In any case, seems like a good idea.
YupAnd it ain't me saying it, it's Stuart Phillips and Co. - I just dork out on research
