So I've read nothing but positive things about gf pro as a supplement, but decided to research the spray dried plasma ingredient.
Turns out it's blood collected from slaughterhouses, then spray dried and put in everyone's beloved protein shake... say whaaat?
Usually, this "Spray dried bovine serum plasma" is fed to pigs and baby calves.
I usually try to stay away from 'crazy' supplements, and I'm not sure I'm going to be buying GF Pro anytime soon. Looking up the ingredients is like taking a science course.
We got "Insulin-like growth factor 1 (IGF-1)
"Results of clinical trials evaluating the efficacy of IGF-1 in type 1 diabetes and type 2 diabetes showed great promise in reducing hemoglobin A1C levels, as well as daily insulin consumption. However, the sponsor, Genentech, discontinued the program due to an exacerbation of diabetic retinopathy in patients "
So... pharm companies are testing this on diabetics and its causing them to go blind? Oh... that sounds like something I'd like to take...hmm. This just got approved by the FDA in 2005, and is an approved drug to be given to short kids as a growth hormone...
Lil bit of "Transforming growth factor, beta 1, also known as TGFB1, a human gene"
And some "lactoferrin."
I'd love some intellectual scientific responses, but I figured others would be interested since this product gets so much attention on here.
