I used to use Muscle Milk all the time. It tastes great and has decent numbers, but Ive stopped using it as of late because of an article here on T-mag. In the article “The Naked Truth - Dangerous Creatine” by David J. Barr he talks about G-Amine, which is in Muscle Milk. In the article it states…
“But wait, there?s MORE! Order now and you?ll get another potentially dangerous ingredient for free!” One particular supplement (“SWOLE”) combines GPA with another potentially dangerous substance known as Glycocyamine (G-amine). Sadly, G-amine (also known as guanidinoacetate) has been picked up by a few different supplement companies who obviously don?t do any research on what they?re getting people to ingest.
The reason G-amine is so popular (from a marketing standpoint, not from the consumers?) is because it is the precursor to creatine. Just like Testosterone can come from andro, creatine comes from G-amine. The theory is that you jack up G-amine levels and you get a whole bunch more creatine. The really asinine part is that, you can just directly take creatine!
Unfortunately, consuming this chemical seems to have the undesirable effect of elevating blood levels of a substance called homocysteine, which is a very strong risk factor for cardiovascular disease (Stead et al., 2001). Cardiovascular disease is easily the number one killer in the Western World, and the last thing we need to do is increase our risk for it. Conversely, taking creatine decreases homocysteine levels, raising even more therapeutic possibilities for this supplement. As if to spit on your grave, if you?re supplementing with creatine, G-amine may also decrease its uptake by muscles (Zugno et al., 2003)."
Take this information however you want. As for me, I threw out my Muscle Milk, and wont touch anything with these ingredients in them. I also dont want to touch anything from a company that doesnt do enough research on what they’re putting into their products. Now I just stick to Grow!. I know that Biotest looks into what they put into their products and I trust them.
Personally I’d rather have a healthy heart than a good tasting protein.
