Apparently not according to this article over at T-Muscle:
Granted, there is a not so stealth attempt to pimp their own products (as in most of the articles on there) but there's some other good info. I'm interested to see what the other Primals think.
nb, that link is work safe, but there are quite a lot of figure model glute pictures on other parts of the site, for those that care.
I'm out of this one before it even starts. I'm not going here again.
