Mex gear that i -ve used before - Salud Animal Lab(rate- 7 out of 10) - good shit, Nutrivet - garbage( 0 out of 10), DK - very good gains, but constant feeling of sickness , from start of cycle to the end ( rate - 6), pretty much - not a big fan of mex gear. However I've heart only good stuff about Stallion so far - and I hope it's really as good as people say....
