so 8 wks at 500mg per wk. You should have 4mls left if you had 2 bottles. I wouldnt bump the test for your next cycle, get your diet in check first bro because I had a friend that gained 17lbs from that same test only cycle. It's either diet or bunk gear. oh and another thing is vet grade is just as good as human grade gear. Human grade is like 99.999% pure, where as vet is like 98%. That extra 1mg wont make for a noticable difference.
