Pre Mixing your Protein
I like to buy my protein in bulk. I also get annoyed with making a shake everytime I finish working out. I have lately been pre mixing my shakes and then just storing it in a jug in the fridge. I am sure this is ok but I have noticed some settling at the bottom. I don't want to lose any quality.

Also, what are you thoughts about putting your glutamine or creatine in with your protein. I have tried different routes?

I was always told not to premix your creatine. I yanked this from another site which should explain it:


When creatine sits in a liquid for any extended length of time it will breakdown into creatinine. Creatinine is the end result of catabolized creatine. You don't want this to happen because it will render the effects of creatine useless by this breakdown into creatinine. This is why the liquid creatine supplements were never successful. They were faulty by design because creatine is very unstable in a liquid.

Yeah I was aware of pre mixing creatine, I was talking about adding it with your protein or with your glutamine

There should be no problem there as long as its unflavored. Fruit punch and chocolate don't go well together :D
I mix my glutamine and micronized creatine into my PWO drinks too. Just make sure to get some dextrose or other simple carbs to help the creatine absorbtion.

Thanks for the info. I didn't know that about creatine. On occasion, I would pre-mix my protein drink, and creatine. I usually drink it within several hours.

Creatine is a pretty stable compound, it wont disintegrate that fast, as long as u r not keeping it in the cooler for more than 12 hrs, you will be ait.

I dont want u all to think that I am just saying stuff just because I want to. Here is a quote from David Tolson's CEE review.

The most common argument against creatine supplementation is that it has a low bioavailability. First, it is argued that creatine is unstable in solution, and particularly in acid, so only a small amount survives the gastrointestinal tract. This isn't true - "unstable" is a relative term, and the degradation half-life (the time it takes for 50% of the creatine to degrade) in the GI tract can still be expected to be in the range of a week to a few months. The authors of what is perhaps the most extensive review of the pharmacokinetics of creatine to date estimate that about 2% of a 5 gram dose would be converted to creatinine (the inactive creatine byproduct) in one hour in the conditions of the GI tract, so "the conversion of creatine to creatinine in the GI tract is probably minimal regardless of transit time" [1].

I used to do the same with my protien, but the longer it sits in the fridge the more nasty i thought it tasted. It used to get a hard film over the top after about 12 hours or so. but then again that is back in the day, when designer whey first came out.

as an aside, why do you guys even bother with glutamine ... its pretty much uselsess.
