Alot of the QV products coming into my area are not what they are labeled to be. Having observed the side effects and gains vs. the dose used, I would say alot of the enathate here seems to be prop, or something else. A couple guys I know are claiming that the injection sites hurt, and they seem to retain ALOT more water and have more acne that one would expect on those doses unless they were actually injecting 600 mg of prop a week, all at once rather than a longer chain ester such as enathate. Others seem to do well though. Its popular with the broke college kids between 18 and 21, because QV products can be obtained very cheap.
