I see vegetable glycerin mentioned a few times. What's the dose on this? Is it any way related to GMS?
Does any one know of a capped GMS source? The powder is really hard to get down.
I used to get the powdered version, but it was not water soluble by ANY means - felt like sand paper going down. I remember shaking the bottle before each sip, and it literally sounded like a baby rattler.
I wouldn't opt for the capped version of Glycerol Mono though, going with a pure Vegetable Glycerine is the best avenue to get in an appropriate dose, which also has a natural sweetness. Something interesting that I ran across in my research was actually in last month's Flex magazine - VG was given an entire side-column write up, in which they suggested 80g taken 1 hour before the workout, since it is slow to absorb and will peak roughly around "go-time."
I'm not sure however, if Flex's recommendation was based on 80g of total product, or carbohydrate content - but it would almost CERTAINLY have to be total product, since the carb content is not very dense at all. Also, something very helpful would be to drink it with a carbohydrate source, at least 30g. I found like Karbo-Lyn works perfectly for this purpose.
You'll know the VG is working when you start sucking down water during and after your workout like a prickly Caryophyllales in a Saharan rain storm!
Here is the exact item I have used for a very long time, with excellent results. I also use it prior to pre-judging with Creatine, Vitargo and Insulin:
