Ive had good luck with mex... QV is pretty good mex IMO...I used a ton of the stuff
I noticed when I switched from galeneka to QV with the same mg, I felt a bit more lethargic and my sexual appetite went down..Ive heard galaneka was overdosed in some cases though so that might be it but I think most mex, your getting about 75% of what you pay for..But I get it cheap, so I just shoot a little more...
