over the last 20 years or so i have used nearly everything that hit the market. starting back long before the china scene was even on the radar. During those days we used serostim/humatrope mostly. I used alot of chinese generics in the years following and just never felt the same...until i started mexis greens...they are every bit as effective (anecdotally of course) then anything i have ever used. I would give them 3 thumbs up but i only have two.
I'm taking mexi's greens by themselves (no aas) and I constantly get accused of being on juice. I'm super lean, holding my size, and getting a nice little pump when I lift. I'm about to see how they compare to Humatrope.
Everyone's immune system responds differently. One person may over react as another, may not at all. This however does not negate the contamination the one person's body picked up on. There was something there that the body said, "Uhh, get out!" and fought against it.
