I think this is a good example of something looking far different on paper than it actually is. I've had these discussions many times, but the fact is that I've used a lot of prop, enth, cyp, etc. and in every single case you feel the effects of the prop much sooner. the same effects were experienced by everyone that I've trained or helped through cycles. on paper the enth may be reaching peak levels quicker, but you simply don't feel it sooner, it takes much longer than with prop to feel the effects. perhaps it has to do with the rate of release, I couldn't really say being that I lack the formal education to explain it, I just know from experience how it works.
