Simply because I trust them. Marc Lobliner from MTS is the man and I have rolled with him several times, and Cellucor is a better replacement for Europe -- where the real problem is -- since they have an international presence.
Many people reading would likely ask "now what?" so they deserve an answer.
If you are asking if it's profit-driven, the answer is no. If someone bought MTS through our website, we'd actually make less than had they bought Dymatize. Same goes for Cellucor, depending on the product.
