“The Blue Tops”: IGF-1 LR3
by Ronny Tober
In the previous issue of Body of Science we published an other analysis of a IGF-1 LR3 sample we bought in the Netherlands and that originated from China. It turned out it was a very dangerous item that contained rat insulin instead of IGF-1 LR3! This time we are back doing protein analysis. In this case, we are again looking at IGF-1 LongR3. We obtained this vial of IGF-1LR3 from China, the principle source country of all IGF-1LR3. We did our best to pick a product that was popular, and thus was representative of the quality of many IGF-1LR3 samples. The results were, again, concerning.
