Honestly? They have a bad reputation, but they really, seriously do TONS of research on their products. I would bet a lot of money that they do more research than nearly every other supplement company combined. You know the pics of doctors in lab coats that look so fake in their ads? They aren't fake. They are doing researching with so many real universities and spending a lot of money to do it.
They do testing on EVERY batch to be sure that their label claims are accurate.
The feedback we get from customers is that their products do work. They were more expensive, but we just lowered ALL MuscleTech products prices on Monday by a good amount.
They have a bad rep because of their advertising. They actually do have substantation to back up their claims (we asked them for it once when we needed it for a lawyer and they had it all to us within hours). They are "gimmicky" in their ads, which WORKS but also pisses people off.
I would bet that 90% of the MuscleTech haters have never even tried a MuscleTech product.
Also, MuscleTech is different now than they used to be five years ago. They learned a lot.
The people at MuscleTech are great. You would be surprised.
