EQ takes a long time to work. i would use it for at least 12-14 wks. ideally, i would run it for 16 wks. still, it isnt as though you will get no benefits at 10 wks. i just feel that it doesnt start physically showing results for much longer than most AAS. the gains will come on slow but consistently.
personally, i don't like using water based injections, as it is a lot easier for bacteria to thrive in water vs oil. injectable winny may be less toxic on the liver, as it misses the liver on it's first pass into the blood stream, but ovreall, it is the exact same compound. results should be the same, but IME, injecting seems to have a slightly stronger effect
